Dear readers,

The construction and real estate economy are in a state o change: energy eciency,

resource protection, residential and workplace health, value retention and risk mitigation

are now in ocus. General conditions and market interests are changing. Thereore, in the

uture buildings will be planned, built and operated dierently.

Against this background, the German Sustainability Building Council (DGNB) together withthe Federal Ministry o Transport, Building and Urban Aairs (BMVBS) developed a voluntary

certication system or sustainable buildings. It was developed by experts rom the complete

value chain o the construction and real estate sector and gives a clear orientation or this

uture-oriented economical sector. We are pleased to present the certication system in this

brochure.

The 2008 version o the German certication system is available or oce and administra-

tion buildings. The practical experience gained during the certications test phase as well

as a numerous comments rom the proessional world will be included in the development

o the 2009 version. Parallel to this, the fexible rating system is being developed step-by-step or other construction types. As previously, experts will be involved in the development

process. This decision process is pushed orward by the non-prot-organisation DGNB as

driving orce and moderator.

The DGNB considers itsel to be the central organization or exchange o knowledge, proes-

sional training, and or a raising public awareness or sustainable construction in Germany.

The ocus o the DGNB is the development o the certication system that is described in

detail at the ollowing pages.

German Sustainable Building Certicate

Sustainable building means to build intelligently: The ocus is on

a comprehensive quality concept that serves the building and real

estate sectors, as well as society in general. Sustainable properties

are benecial to the environment, conserve resources, comortable

and healthy or their users, and t optimally into their socio-cultural

surroundings.

In the same way, they stand or economic eciency and long-termvalue-retention. Sustainable properties are cost eective due to

their lower operation and maintenance costs. The manageable ad-

ditional planning and construction costs will usually amortize in a

ew years.

The German Sustainable Building Certicate was developed by the

German Sustainable Building Council (DGNB) together with the

Federal Ministry o Transport, Building, and Urban Aairs (BMVBS)

to be used as a tool or the planning and evaluation o buildings in

this comprehensive perspective on quality. As a clearly arranged andeasy to understand rating system, the German Sustainable Building

Certicate covers all relevant topics o sustainable construction, and

awards outstanding buildings in the categories bronze, silver, and

gold. Six subjects aect the evaluation: ecology, economy, social-

cultural and unctional topics, techniques, processes, and location.

The certicate is based on the concept o integral planning that de-

nes, at an early stage, the aims o sustainable construction. In this

way, sustainable buildings can be designed based on the current

state o technology, and they can communicate their quality withthis new certicate.

X The German certicate makes sustainability measurable andcomparable.

For planning and ealuation o buildings, tere is a ne

and clearl structured tool: Te German Sustainable Build-

ing Certifcate. As meritocratic rating sstem, it coers all

releant topics o sustainable construction. Outstanding

buildings are aarded in te categories bronze, siler, or

gold.

Active Contribution to Sustainability

The certicate demonstrates, in a quantiable way, the positive e-

ects o a building on the environment and on society.

Cost- and Planning Certainty

The certication process provides, in the early planning stage, a high

degree o certainty that the perormance goals o a building can be

reached at the time o completion. For example, it helps reduce theenergy consumption and costs during operation.

Minimizes Risk

The certication process promotes integral planning during

construction. This leads to more transparency and well-dened

processes during planning and construction, opens up potentials or

optimization, and minimizes the risks during construction, opera-

tion, renovations, and removal.

Praxis-oriented Planning ToolThe certicate was developed by practitioners or practitioners. It

supports owners and designers in a goal-oriented way in develop-

ing sustainable buildings.

Focus on the Lie Cycle

The certicate is based on the lie cycle o a building, which is indis-

pensable or an evaluation o the sustainability.

Made in Germany

The certicate is optimally adapted to the German and Europeanbuilding environment. This includes building codes and norms, as well

as long-term market experience with energy ecient buildings etc.

Marketing Tool

The certicate serves as a communication tool or investors, owners,

and users it documents their commitment to sustainability. As a

sign o quality, it supports export, and it enhances the attractiveness

o the German real estate sector or investors.

Comprehensive Quality o a Property

The certicate enhances the chances or sale and rent. The certi-cation makes the high quality o a building tangible or owners

and users. Furthermore, it signals a perormance-enhancing work

environment as well as high user satisaction.

The Perormance is Key

The German certicate evaluates the buildings perormance and

not merely single measures. Owners and designers are given a large

leeway to achieve the targets.

More than Green BuildingThe certicate ar exceeds the ecologic aspects o green building

by also equally including the economic perormance, as well as

socio-cultural and unctional aspects o buildings.

Flexibility

The certicate system can fexibly be updated. It can easily be

adapted to technical, social, and international developments.

06


I an owner wants to gain a certicate or a planned building, he

assigns an accredited DGNB auditor who, due to his training, is

amiliar with the requirements o the German Sustainable Building

Certicate. The auditor accompanies the owner on his/her way to

certication. The auditor advises the owner on all issues concern-

ing sustainable construction, ormulates the goals or the planned

building, and makes sure that the planning team implements the

agreed-upon sustainability criteria. The auditor summarizes thegoals o the project in a comprehensive object-specic specication

sheet.

Registration

To start the certication process or the planned building, the audi-

tor registers the object at the DGNB website www.dgnb.de.

Issuance o the Pre-Certifcation

Ater registration at the website, the auditor submits the object

specic specication sheet to the DGNB. It contains the dataregarding all criteria o the German Sustainable Building Certica-

tion and is a binding declaration o intent by the owner to realize

the planned perormance goals. The DGNB checks the documents

submitted by the auditor. I they comply with the requirements o

the certicate, the owner receives a pre-certicate or his building.

He therewith assumes responsibility or the implementation o the

discribed measurements. At the same time he is entitled to use this

pre-certicate in gold, silver, or bronze or the promotion o his

property.

ThE PAThwAy TO CERTIFICATION

Documentation

On this basis, the building design and construction can be started.

The consulting auditor is to establish an accompanying planning

and construction documentation in accordance with the specica-

tions o the DGNB documentation guidelines.

Inspection o Conormity

Ater completion o the building, the DGNB checks i the specica-tions o the pre-certicate have been realized. An assessor perorms

a conormity inspection based on the DGNB documentation guide-

lines, makes plausibility checks, and takes control-samples.

Award o the Certifcate

Finally, the DGNB reviews i the entire certication process was ex-

ecuted properly. I all requirements are ullled, the owner receives,

depending on the degree o compliance, the gold, silver, or bronze

certicate rom the DGNB and BMVBS, consisting o a certicate

and a plaque or his building. He may use these in his marketingactivities.

Auditors

Auditors accompany the owners during the certication process. To

be ocially recognized as DGNB auditors, they have to participate

in a multi-week training by the DGNB or by educational institu-

tions that have been accredited by the DGNB, such as Universities

or Chambers. The modularly structured curriculum consists o an

introduction to sustainable construction; it also conveys the relevant

contents or the implementation o the certication system.

X The Seal is awarded in gold, silver, or

bronze.

METhODICAL PRINCIPLES OF ThE CERTIFICATION

SySTEM

The German Sustainable Building Certicate is a transparent

and comprehensible rating system that was developed based on

real-world circumstances. It denes the quality o buildings in a

comprehensive way, and enables auditors to conduct an evaluation

systematically and independently.

Supporting Sotware

User-riendly sotware supports the auditor with the documentationand evaluation process. The sotware visualizes the capabilities o

a building in a way that is concise and easy to understand. Already

during the planning process, it marks the infuencing parameters

were the building can be optimized with regard to sustainability.

Flexibility as Strength

The basis or the system was developed on the building type New

Construction o Oce and Administration buildings. On this basis,

urther systems or completely dierent building types will be

developed. As a second-generation certication system, the labelexcels with a high degree o fexibility. The basis o the evaluation,

which was developed with a wide consensus, is a list o topics and

the criteria or sustainable construction that are included within that

list. These criteria are weighted dierently, depending on the build-

ing type to be evaluated. Thus, each version o the system, hence

each building type, has its own evaluation matrix. An example is the

matrix or the evaluation o new oce and administration buildings

on page 11.

Te bencmarks or aarding te certifcate are orien-

tated on te current state-o-te-art and on an integral

planning statement tat includes te aims o sustainable

construction.

Clear Topics

During the evaluation, 6 topics are considered by the certicate:

Ecological Quality

Economical Quality

Socio-cultural and Functional Quality

Technical Quality

Quality o the Process

Quality o the Location

X The Certicate: For the evaluation o the buildings quality, ve

topics are considered. The quality o the location is presented

separately.

Te interested parties are included during te deelop-

ment o eac ne ersion o te certifcate rom te er

beginning.

The topics are weighted dierently in the overall assessment o the

building, depending on their relevance. For example, or the certi-

cate New Construction Oce and Administration, Version 2008,

both the economical and the ecological quality have the same

weighting (22.5% each). The quality o the location is not included

in the nal grade but is presented separately.

Conclusive Individual CriteriaEach topic is divided into several criteria. For instance, the energy

consumption, acoustical quality, or land consumption are consid-

ered or the evaluation o a building. For each criterion, measur-

able target values are dened, and a maximum o 10 points can

be assigned. The measuring methods or each criterion are clearly

dened.

Detailed Weighting

At the same time, each criterion has a weighting actor: it can fow

threeold into the evaluation o its respective topic. This way, orinstance, the energy consumption o an oce building is o more

importance than the acoustical comort. The weighting actor can

also be zero the consideration o motorway bridges does not

require the criteria or indoor air quality.

Clear presentation o Results

Each criteria fows into the overall result in a clearly dierentiated

way. A sotware-supported computation displays the buildings

perormance: by reaching a dened degree o perormance, it is

assigned the bronze, silver, or gold award. Furthermore, grades are

given or the total perormance o the building as well as or the

individual topics.

Praxis-oriented Continuing Development o the

System

On this basis, the German Sustainable Building Certicate can be

adapted, in a practicable way, to the individual requirements odierent building types. Similarly, it can be adapted to regional

requirements or social developments, or example to the increasing

importance o individual criteria like indoor air quality or CO2-

emissions o a building. The strength o the system is also based on

the involvement, rom the beginning, o interested parties during

the development o new variations. A supplementary commenting

procedure ensures that the requirements o the construction and

real estate sector are systematically queried and included into the

system.

The German Sustainable Building Certicate was initially developed

or new oce and administration buildings. In version 2008, which

emerged rom the pilot phase o the certication system, the sus-

tainability o oce and administration buildings is evaluated based

on 49 criteria.

The Topics

These criteria are distributed among the 6 topics o the system. Fiveo the topics fow into the nal grade: Ecological Quality, Economi-

cal Quality, Socio-cultural and Functional Quality, Technical Quality,

and Quality o the Process. The Quality o the Location is evaluated

separately. It is not included in the overall evaluation o the build-

ings quality, so that each building can be evaluated independent o

its location.

Evaluation Matrix

Each criterion can be assigned a maximum o 10 points, depending

on the documented or calculated quality. All criteria are weightedwith a actor rom 0 to 3, because individual criteria are treated

as either more or less relevant. The evaluation matrix on page 11

shows the structure o the system. The degree o compliance with

the requirements o the certication is calculated in accordance

with the evaluation matrix.

ECOLOGICAL QUALITy 12 CRITERIA

Criterion 01: Global Warming Potential (GWP)

J Goal

Reduction o the Global Warming Potential. The Global Warming

Potential is the potential contribution o a substance to warm the

near-surace air or the so called greenhouse eect. The contribu-

tion o the substance is indicated as GWP-value in relation to the

greenhouse potential o carbon dioxide (CO2). For the certicationthe GWP 100 value, which is the contribution o a substance to the

greenhouse eect over a period o 100 years, is used.

J MethodologyEvaluation o the greenhouse potential o the construction,

operation and disposal o a structure over a period o 50 years

(kg CO2-Equiv./mNFA*a). The input quantities can be gained rom

the operational phase o the energetic proo according to the Ger-

man regulation or energy saving in buildings and building systems

2007 (EnEV 2007 = in German: Energieeinsparverordnung 2007).For the identication o the ecological impacts o the buildings

construction, including its systems engineering, an eco-accounting

o the used materials and/or building parts according to DIN EN

ISO 14040 and 14044 is necessary. The required datasets or this

are provided via the inormation portal or sustainable building. For

the evaluation o the construction, including the systems engineer-

ing, reerence values are dened on the basis o an average oce

building. The evaluation o the Global Warming Potential criterion

is based on an average annual value o the realized building, which

is compared to the annual reerence value.

J Data BasisThe data identication (eco-balance as well as calculations o EnEV)

is largely the same or the criteria 01 to 05 and 10 to 11. By enter-

ing the building data into the appropriate sotware, the lie-cycle

costs can be calculated simultaneously.

Nutzungsdauern von Bauteilen

Criterion 02: Ozone Depletion Potential (ODP)

J GoalReduction o pollutant emissions that contribute to the destruction

o the ozone layer. Ozone is able to absorb short-wave UV-rays

and emit longer wavelength radiation omnidirectionally. The ozone

layer shields the earth rom a large part o the UV-radiation,

prevents excessive warming o the earths surace, and contributes

to protecting us rom UV-A and UV-B radiation. The accumulationo R

11-equivalent in the atmosphere contributes to the destruction

o the ozone-layer. Consequences are e.g. tumour generation in

humans and animals, as well as disruption o photosynthesis.

J MethodologyThe input quantities or the operating phase can be taken rom

the energetic documentation according to EnEV 2007. For the

determination the ecologic impacts o the buildings structure,

including the systems engineering, an eco-accounting o the used

materials and building parts according to DIN EN ISO 14040 and14044 is necessary. The required datasets or this are provided via

the inormation portal or sustainable building. For the evaluation

o the construction, including the systems engineering, reerence

values are dened on the basis o an average oce building. The

evaluation o the Ozone Depletion Potential criterion is based on

an average annual value o the realized building, which is compared

to the annual reerence value.



ing the building data into the appropriate sotware, the lie-cyclecosts can be calculated simultaneously.



Criterion 03: Photochemical Ozone Creation

Potential, POCP

J GoalReduction o photochemical ozone creation potential the mass-based equivalent o destructive trace gases (e.g., nitric oxide and

hydrocarbons). These, in combination with UV-radiation, contribute

to the ormation o near-surace ozone. The human- and eco-toxic

contamination o the near-surace air is called summer smog. It

adversely aects the respiratory system and damages plants and

animals.

J MethodologyThe lower the photochemical ozone creation potential (summer

smog) is, the better is the evaluation (in kg C2H4-Equiv./mNFA*a).The input quantity or the operating phase can be taken rom the

energetic proo according to EnEV 2007. For the classiying the

ecologic impacts o the buildings structure, including its systems

engineering, an eco-accounting o the used materials and/or o the

building parts according to DIN EN ISO 14040 and 14044 is neces-

sary. The required datasets or this are provided via the inormation

portal or sustainable building. For the evaluation o the construc-

tion, including the systems engineering, reerence values are

dened on the basis o an average oce building. The evaluation o

the Photochemical Ozone Creation Potential criterion is based on

an average annual value o the realized building, which is compared

to the annual reerence value.







Criterion 04: Acidication Potentialpotential

J GoalReduction o Acidication Potential. Acidication means rising o the

concentration o H-ions in the air, water and soil. Sulphur and ni-

trogen compounds rom anthropogenic emissions react in the air to

orm sulphuric and/or nitric acid that alls to the earth as acid rain

and negatively impacts water bodies, creatures, and buildings. The

sum o the individual acidication impacts leads to orest dieback

and sh mortality. Acidic precipitations corrode historical buildings(sandstone). The evaluation criterion or this environmental impact is

the acidication potential as is indicated by SO2

equivalents.

Criterion 05: EutrophicationPotential (EP)

J Goal

Reduction o Eutrophication. Eutrophication describes the transi-

tion o water bodies and soil rom a nutrient-poor to a nutrient-rich

(a.k.a..eutrophic) state. This state is mainly caused by supplying

phosphor- and nitrogen compounds. These compounds can getinto the environment via abrication o building materials and via

washing-o o combustion-emissions. The change in available nutri-

ents e.g., increases the ormation o algae in water bodies , which

can lead to higher sh mortality, among other things.

J MethodologyThe input quantity or the operating phase can be taken rom the

energetic proo according to EnEV 2007. For the classiying the

ecologic impacts o the buildings structure, including its systems

engineering, an eco-accounting o the used materials and/or othe building parts according to DIN EN ISO 14040 and 14044

is necessary. The required datasets or this are provided via the

inormation portal or sustainable building. For the evaluation o

the construction, including the systems engineering, reerence

values are dened on the basis o an average oce building (type-

representative). The nal evaluation o the Eutrocation Potential

criterion is based on an average annual value o the realized build-

ing (structure and use), which is compared to the annual reerence

value. The lower the eutrophication potential is, the better is the

evaluation (in kg PO4-Equiv./mNFA*a).



J Methodology

The lower the acid potential, the better is the evaluation (in kg

SO2-Equ./mNFA*a). The input quantity or the operating phase can

be taken rom the energetic proo according to EnEV 2007. For the

classiying the ecologic impacts o the buildings structure, including

its systems engineering, an eco-accounting o the used materials

and/or o the building parts according to DIN EN ISO 14040 and14044 is necessary. The required datasets or this are provided via

the inormation portal or sustainable building. For the evaluation

o the construction, including the systems engineering, reerence

values are dened on the basis o an average oce building. The

evaluation o the criterion Acid Potential is made by an average

annual value o the realized building (structure and use) that is

opposed to and adequate specic reerence value.

Criterion 08: Other Impacts on the Global

Environment

J GoalThe impacts o a building on the global environment shall be

reduced. A central aspect is the proo o the use o certicated

wood. Subtropical and boreal woods are only allowed to be used

i the supplier can certiy the controlled, sustainable cultivation othe orest o origin. Only certicates that are issued by the For-

est Stewardship Council (FSC) or certication authorities that are

accredited by the Program or Endorsement o Forest Certication

Schemes (PEFC) are accepted. The certication criteria o sustain-

able orestry established by the FSC have international consensus.

For the veriability, the supplier has to declare both the country o

origin and the woods species. An FSC-certicate is only valid in

combination with the appropriate FSC-trade certicate chain o

custody.

J Methodology

Action Level 1: No use o tropic, sub-tropic, or boreal wood. No

proo required.

Action Level 2: Use o at least 20% o FSC- or PEFC certicated

wood or wood-based materials, independent o country o origin or

wood species.

Action Level 3: Use o at least 50% o FSC- or PEFC certicated

wood or wood-based materials, independent o country o origin or

wood species.

J Data BasisThe quantication is taken rom the amounts provided in the

request or bids. The use o certied wood has to be veried by the

declaration o the products.





Criterion 06: Risks or the Local Environment

J GoalThe risks or the local environment are minimized through a pur-

poseul choice o building materials that come in contact with the

surrounding air, soil, and surace- and/or groundwater during the

operation o the building.

J MethodologyMaterials and substance types that can cause environmental risks

are queried individually and on a per-product basis. Substance types

that are considered are halogens, heavy metals, organic solvents,and substances and products that all under the biocide- and

REACH guidelines. There are 4 dened action-levels that build on

each other. The requirements o a higher action-level include the

successul implementation o all requirements o the level below

it. Each action-level contains a list o materials and products to

be avoided. The more action-levels that can be ullled, the lower

the risks or the local environment are. Proo or the successul

implementation includes: declarations or the required materials

and products, submission o material and product lists, and a test

certicate that conrms the compliance o the declared and usedproducts and materials with the requirements.

Criterion 10: Non-Renewable Primary Energy De-

mands (PEne

)

J GoalThe use o non-renewable energy resources shall be reduced. With

the identication o the non-renewable primary energy demands,

the energy-eciency o the construction and use, as well as the

energy demands o the upstream chain is evaluated. The energydemands o the users equipment are not evaluated. Primary energy

is the energy that is available rom naturally existing energy sources.

Included are non-renewable energies such as black coal, brown

coal, petroleum, natural gas, and uranium.

J Methodology

The demands o non-renewable primary energy is calculated

over the lie-cycle o construction, reconditioning, operation, and

deconstruction/disposal o a building (in kWh/mNFA*a). The input

quantities or the operating phase can be taken rom the energeticproo according to EnEV 2007. For the classiying the ecologic

impacts o the buildings structure, including its systems engineer-

ing, an eco-accounting o the used materials and/or o the building

parts according to DIN EN ISO 14040 and 14044 is necessary.

J Data Basis

The data identication (eco-balance as well as calculations o EnEV)



costs can be calculated simultaneously.www.nachhaltigesbauen.de:> Bausto- und Gebudedaten >


The eco-balance (kobilanz) supplement has to be considered

or the calculation o the non-renewable primary energy demands.

Criterion 09: Microclimate

J GoalThe choice o appropriate products and solutions shall reduce the

negative impact on the micro-climate o roos and aades, which

can contribute to heat islands.

Cities are signicantly warmer than rural areas due to the intense

warming-up during the daytime and the limited cooling-down atnight. This heat island eect can be compensated by creating

unsealed areas, greening, or the use o materials with low solar

absorption.

J MethodologyDocumentation o the roo- and aade materials with the aid o the

reerence table Albedo Values (Albedowerte).

Action Level 1: Documentation o character, colour, surace texture,

as well as the appropriately determined refection values (Albedo),absorbency, emissivity, and transmissivity o the roo and soil mate-

rials. Unsealed and planted areas are also documented, according

to their size and nature, on technical drawings. Further, inormation

concerning the surroundings o the building, such as the mass o

surrounding buildings, street-widths, and heights o the surrounding

buildings, as well as the orientation o the building is supplied. This

can be documented with photos and property- and elevation plans.

Action Level 2: Additional documentation o the acade material.

Nutzungsdauern von BauteilenNon-renewable primary energy can be transerred rom criterion 10.

Criterion 11: Total Primary Energy Demands and

Percentage o Renewable Primary Energy

J GoalThe total demand or primary energy shall be minimized and the

percentage o renewable energy shall be maximized during the lie

cycle o a property. Among the non-renewable primary energies

are black coal, brown coal, petroleum, natural gas and uranium;and among the renewable energies are biomass, solar radiation,

geothermal energy, hydropower, and wind energy. The total value o

primary energy demands are evaluated, as well as the percentage

o renewable energy demands, as compared to the total primary

energy demands.

J MethodologyThe percentage o renewable energy as compared to the total

primary energy demands or the construction and use is evaluated

over a period o 50 years. The input quantities or the operatingphase are taken rom the energetic proo according to EnEV 2007.

Here, diering rom EnEV 2007, the standard is a coverage propor-

tion o 15 % o the heat-demand by solar heat. For the classiying

the ecologic impacts o the buildings structure, including its systems

engineering, an eco-accounting o the used materials and/or o the

building parts according to DIN EN ISO 14040 and 14044 is neces-

sary. For the evaluation o the construction, including the systems

engineering, reerence values are dened on the basis o an aver-

age oce building. The evaluation o the criterion Percentage o

Renewable Primary Energy is made by comparing the percentageo renewable energies regarding the total primary energy demands

o the realized building with the reerence building.

Criterion 15: Surace Area Usage

J GoalThe constant increase in trac and settlement areas shall be

reduced. Preerably, areas shall be used that are already assigned as

trac or settlement areas or that are allocated or the recovery o

contaminated locations.

J MethodologyIt is evaluated, in which degree and in which sense the type o area

consumption is changed by the construction project. Area is not

consumed, but a usage-change o the area takes place.

1. The previous use o the area can be determined rom the certi-

cates o title or extracts rom the land survey register.

2. The previous contamination o the property by contaminated

sites, munitions, etc. can be determined based on available

survey reports.3. The realization o compensation measures can be identied

based on available documents.

4. Based on the planning documents, it is checked i a greened roo

is planned, and can be approved as a compensation measure.

5. The type, extent, and direction o change o the actual use o the

area are recorded and evaluated (change rom nearly natural

to cultivated = negative; change rom contaminated area to

cultivated area = positive).

Criterion 14: Potable Water Consumption and Sew-

age Generation

J GoalPotable water consumption and sewage generation shall be

reduced. Despite the ample supply o water, there is a deciency

o high-quality potable water. Only ater elaborate ltration, where

naturally occurring iron and manganese, pesticides and nitratesrom agriculture, and other harmul substances are removed, can

water be used as potable water. The treatment o sewage in central

sewage treatment plants causes high expenditures, transport in

canalization, and the need or purication. The higher concentrated

the sewage is, the more eective is the purication. Inltration or

usage o storm water is preerable to the mere draining into the

sewage system. Inltration contributes to the stabilization o the

groundwater table, and evaporation contributes to the improvement

o the micro-climate. Storm water can replace potable water or

e.g., fushing toilets.

J MethodologyBy adding the ascertained potable water consumption and the

sewage emergence, the specic water-use value (Wasserge-

brauchskennwert) is generated. This represents a simple value or

the evaluation o the handling o water in the building. The basis or

the evaluation is established with the aid o dened assumptions

concerning consumer behaviour and specic values.

Criterion 17: Value Stability

J GoalA globalized and international market demands high eciency,

fexibility, and adaptability. This is also refected in the utilization

o buildings. A building designed or sustainability can be easily

adapted to changing requirements. Change in the usage can result

rom tenant or user changes, and also rom reorganizations by thetenant. A high level o adaptability o buildings under the criterion

o sustainability is present, i the alteration can be realized with a

small amount o resources.

J Methodology

Area eciency and adaptability o a structure are evaluated with a

checklist. The criterion is based on the utilization phase o the struc-

ture. The largest opportunities to infuence the direction are during

the project development and planning phases. The better a building

can be altered and the less elaborate an alteration is, the better theability to alterate is rated. Considerable resources savings can be

achieved by considering the optimization o area utilization in an

early planning phase. The ollowing indicators are checked:

1. Proo o inspection o the area eciency

2. Modularity o the building

3. Spacial structure o the building

4. Electrical- and media provision

5. Heating, climate control (HVAC), water supply, and sewage

disposal

Criterion 16: Building-related Lie Cycle Costs (LCC)

J GoalSome o the goals o economic sustainability are the minimiza-

tion o a buildings lie cycle costs and the relative cost reduction

o alteration and preservation investments in comparison to new

constructions. In the past, the conventional planning and con-

struction process was ocused mainly on the minimization o themanuacturing costs o a building. The ollow-up costs receive only

little consideration. However, current cost savings shall not be made

at the expense o the uture users and owners. Since the ollow-up

costs thereore need to receive more consideration, the expected

ollow-up costs have to be evaluated. For this, only the building-

specic costs are included.

J MethodologyThe lower the lie cycle costs according to the cash-value method

(Barwertmethode) (in /mNFA), the better is the evaluation. Liecycle costs o a building are all costs that arise during the entire

useul lie o a building. The costs beginning with the project deve-

lopment up to construction and handover are dened as production

costs. The costs rom commissioning up to disposal are dened

as ollow-up costs. The lie cycle costs are divided into three cost

categories: production costs, ollow-up costs, and deconstruction

and disposal costs. The largest opportunities to make decisions and

improvements are during the project development and planning

phases.

Criterion 23: User Infuences

J Goal

Goal is the maximization o the user infuence capabilities in the

sectors ventilation, sun protection, visor, temperature as well as

regulation o daylight and articial light at the workplace.

J MethodologyWithin an early and integral planning o measures that convey the

users infuence at the workplace, comort can be conveyed. Ad-

vancement o comort leads to increased satisaction and achieve-

ment o users in oce and administration buildings. A checklist

o the possible infuence by users is evaluated with the ollowing

criteria:

1. Ventilation

2. Sun protection

3. Visor4. Temperatures during the heating period

5. Temperatures outside the heating period

6. Regulation o daylight and articial light

Criterion 22: Visual Comort

J GoalVisual comort shall be achieved by balanced illumination with-

out appreciable intererences such as direct and refected glare, a

sucient illumination level and the possibility to adjust illumina-

tion individually to the particular needs. Vitally important or the

workplace contentment is the view that inorms about time o day,location, weather conditions etc. Further criteria are nonglaring,

light distribution and spectral colour in the room. The requirements

are valid both or illumination by daylight and articial light.

J MethodologyBy an early and integral daylight and articial light planning, a high

quality o illumination can be created with low energy demands or

illumination and cooling. Furthermore, a high degree o daylight

use can enhance workplace capability and health and reduce the

operational costs. In a checklist the visual comort is evaluated:

1. Daylight availability or the entire building (quantitative)

2. Daylight availability or the permanent workplaces (quantitative)

3. Visibility to the exterior (quantitative)

4. Non-glaring daylight (quantitative)

5. Non-glaring articial light (quantitative)

Criterion 24: Roo Design

J GoalThe entire roo area should be designed. The integration o the roo

in the design o the building and its surroundings shall enhance the

development o a three-dimensional urban surrounding. Utiliza-

tion o this area can reduce the CO2-emissions and can improve

the microclimate. Besides the designed integration o the techni-cal superstructures, the roo can improve the general welare with

suitable areas. Such areas are greened roos, solar-active areas,

socio-cultural utilizations such as roo terraces, historical reerences

to the direct surroundings such as choice o material and colour o

the roong in historical city centres.

J MethodologyThe roo design is prooed with reerence to planning documents.

The areas or technical superstructures have to be reduced to a

minimum and the louvers shall be integrated in the design. Func-tional suraces or the general welare are to be integrated in the

roo area.

Criterion 25: Saety and Failure Risks

J GoalDanger, accidents and catastrophes shall be avoided; saety shall

be assured as ar as possible i accidents or catastrophes happen.

Insecurity and anxiety can constrain the movement o humans. The

subjective sensation o saety contributes basically to the comort o

humans. Objective saety is present i actual dangers are avoided oror example with accidents i the extent o damage can be reduced

Criterion 27: Area Eciency

J GoalAreas should be handled as economical as possible. Area eciency

is an index or the utilization o foor space inside buildings. A report

by the German Society o Real Estate Funds (Deutsche Gesellschat

r Immobilienonds) states that 2/3 o the project developers

consider the actor area eciency as a superior planning item. Withreerence to the augmentation o area eciency the ollowing goals

or improvement can be presented:

1. Optimization regarding costs

Decrease o construction and operational costs, avoidance o

restricted use areas.

2. Environmental Optimization

Reduction o the property environmental impacts during operation,

by reducing the technical equipment required or heating, ventila-tion, and cooling. With increased area eciency the sealing o

natural soil can be reduced.

3. Contribution to optimization in the social sector

Positive interaction in the working environment with well propor-

tioned areas and a clearly arranged design.

J MethodologyThe specic value area eciency corresponds to the proportion

between usable foor space to gross foor area (in m/m).

Criterion 26: Barrier-ree Accessibility

J GoalBuildings shall be constructed barrier-ree. Barrier-ree accessibility

augments value and attractiveness or all population groups and

concerns or all people with motor and sensory restrictions. The

percentage o these people will increase due to the demographic

shit. This has to be mastered with orward-looking and sustainabledevelopment.

J MethodologyThe evaluation is carried out qualitatively to the degree o barrier

reedom. The allocation o credits is orientated on the possibility o

the equal utilization o the building by all people. The basic accessi-

bility has to be assured. Without this basic accessibility no certi-

cation or a new construction can be assigned. The more parts o

the building that are adapted to the needs o disabled persons the

better the whole building is rated. Also the external eature areashave an important benet value and are thereore also included in

the evaluation. The evaluation is orientated on the actual standardi-

zation.

Criterion 28: Conversion Feasibility

J Goal

The better a building can be converted with as little time and eort

as possible, the better the attribute Feasibility o Conversion

is evaluated. The globalized and international market demands

high fexibility and adaptability. This is also refected in the use o

a building. A sustainable designed building can easily be adaptedto changing requirements. Change o use can result rom tenant/

user change as well as rom user reorganization. A high degree o

sustainable building conversion easibility is present i a change can

be realized with low resource consumption.

J Methodology

With a checklist the conversion easibility is analyzed on our levels:

1. Modularity o the building

2. Spatial structure3. Supply o electricity and other media

4. Heating, supply and disposal o water

Criterion 29: Accessibility

J GoalAcceptance and integration o a building inside a district, city and

region shall be enhanced by increased accessibility. Public acces-

sibility enhances social communication. A diversity o use generates

vitalization o the public space and augments the sense o security

o the users. At the same time it contributes to the economic sus-tainability o the building.

J MethodologyWith a checklist the ollowing topics are evaluated:

1. Basic accessibility o a building

2. Opening o the external areas or public

3. Opening o buildings acilities to public such as library or

caeteria

4. Possibility o a third party renting building space

Goal is the establishment o more than a ree rentable unit with

dierent usage preerably on the ground foor. The ocus is on

the ground foor because it can be best utilized or public usage

(accessibility, visibility, urbanistic unction). A combination with the

adjacent foors is possible. At least one type o public usage should

be present in the building or onsite.

Criterion 30: Bicycle Comort

J GoalThe percentage o cyclists shall be raised. As the larger number

o car journeys is shorter than 5 km, the change to bicycling can

contribute signicantly to the development o an ecologically sound

and energy ecient mobility. Missing building-specic inrastructure

or bicycles in praxis oten leads to wild parking in the publicspace. Undervalued bicycle comort oten leads to breakdown o the

bicycle inrastructure and cannot be compensated.

J Methodology

The bicycle comort is evaluated in a checklist with the ollowing

topics:

Art o arrangement o the bicycle storing positions and required

space

Quorum o storing positions per m NFA Are the storing positions located in ront o the main entrance?

Are the storing positions located in a proper distance to the

main entrance?

Do the oered storing positions meet the unction o the build-

ing

Are showers and changing rooms with drying acilities or the

employees bicycle clothes present?

J GoalPlanning competitions shall take place to attain the best solution

or the architectonical and constructive tasks. With this, the architec-

tural diversity in Germany is assured. An expert jury can judge best

architectonical solutions and integration into the urban context.Planning competitions in Germany are conducted under standard

regulations. They allow clients to nd the appropriate contractor

within a clearly structured and transparent procedure. Competitions

orward creativeness, innovative solutions and are ecient methods

to optimize quality and protability. With the reward o planning

competitions, alternative solutions are developed that meet the

demands concerning design, protability, unctionality, energy

conservation, and environment protection.

J MethodologyExtent and quality o the conducted competitions have to be identi-

ed:

1. Has a successul competition been conducted according to

GRW95, RPW2008 or a similar method including the evaluation

o the competition entries by a jury?

2. Which competition method was chosen; and does it include the

least number o restrictions?

3. Does the constructed building match in extent and quality the

essence o the award-winning competition entry?

Criterion 32: Art within Architecture

J GoalArt within architecture shall be enhanced. It is an element o

architecture that orms quality and expressiveness o the building

and is thereore an integral part o the construction job and the

responsibility o the owner. Art within architecture is a creative task

that establishes a direct relationship between building and public.It marks a special object and site relationship and shall contribute

to strengthen acceptance and identication o the users with their

building, to attract attention and to add additional prole to the

location.

J MethodologyIn a checklist the ollowing topics concerning art within architecture

are evaluated:

1. Is art within architecture necessary or the object to be evalu-ated and should an art competition be scheduled?

2. How many o the recommendations o the guidelines art within

architecture were considered:

Consultation with artists and art critics

J Data BasisThe necessary parameters or the calculation can be extracted rom

the state building code, the re protection concept, and the an-

nouncement documents.

Criterion 34: Noise Protection

J GoalNoise protection shall be improved. Minimum requirements o struc-

tural noise protection are dened in DIN 4109. This only addresses

the unacceptable but not automatically all possible noise pollutants.

Additional requirements to noise protection in oce buildings are:

avoiding loss o concentration, protection o privacy and condenti-

ality, and consideration or people with limited hearing.

J MethodologyMeasures that exceed the minimum noise protection requirementslead to a better score. A pointless exceeding o the standards shall

be avoided. The quality o noise protection o building parts is deter-

mined rom the certicate o noise protection or the quality o the

specied building parts. It is evaluated i the building parts comply

with the regulations o DIN 4109 supplement 2 and where the

regulations are exceeded:

1. Airborne noise protection against surrounding noise

2. Airborne noise protection against other workplaces and against

the own workplace3. Impact-sound protection against other workplaces and against

the own workplace

4. Structure-borne sound protection against other workplaces and

against the own workplace

Criterion 33: Fire Protection

J GoalThe quality o re protection measures shall be increased. The main

cause o death involving re in buildings is toxic smoke. Measures

that exceed the re protection regulations can be rated positively.

However, re protection measures that exceed the legal regulations

should also consider the total economic impact as well as additionalemissions caused by the addition amounts o raw materials and

supplies.

J MethodologyA checklist evaluates the ollowing issues, as long as they exceed

Criterion 40: Ease o Cleaning and Maintenance o

the Structure

J GoalWith targeted cleaning and maintenance, the used materials can be

operated or the maximum useul lietime. The ease o cleaning and

maintenance o the structure has a high impact on the costs and

the environment o a building during the operating phase. Areasthat can be cleaned easily require lower expenditures on cleansers

and cause lower cleaning costs.

J MethodologyFor the evaluation, the building is divided into the ollowing three

categories o building parts:

Bearing structure

External non-bearing structure, incl. windows and doors

Interior non-bearing structure

The technical implementation o each section is evaluated. Bymeans o the technical parameters, it shall be identied whether a

structure, based on its technical planning and construction, enables

ecient cleaning and maintenance. The dierent sections o the

construction are considered separately. Criteria or maintenance and

or cleaning are queried.

J Data BasisThe Guidelines or Sustainable Building (Leitaden Nachhaltiges

Bauen) provides ranges or the average useul lietime o build-

ing parts and layers o building parts according to Lie Cycle Costs(LCC) and Lie Cicle Analysis (LCA). The cleaning and maintenance

parameters have a signicant infuence on the useul lietime o

building parts and layers o building parts.

Criterion 35: Energetic and Moisture-Proong

Quality o the Buildings Shell

J GoalThe energy demand or the space conditioning shall be minimized,

high thermal comort shall be assured, and structural damages shall

be avoided. The quality o heat insulation and moisture-proong o

the buildings shell shall be optimized.

J Methodology

Basis o the requirements are the specications o EnEV 2007, DIN

4108, and DIN EN 12207. A higher quality increases the score.

Individual requirements or the parts o the buildings shell are

described. Reerence values are determined with the ollowing

method:

The buildings shell is evaluated with a checklist o the ollowing

criteria:

1. Average heat transmission coecient (qualitative)

2. Consideration or thermal bridges (qualitative)

3. Permeability o joints (qualitative)

4. Formation o condensate (qualitative)

5. Air change rate (quantitative)

J Data BasisThe parameters necessary or the calculation can be extracted rom

EnEV 2007.

J MethodologyThe building is evaluated with a checklist:

1. Building services

2. Non-structural (de)construction parts

3. Non-bearing carcass structure

4. Bearing carcass structure

For each group, the ollowing topics are considered:

Eort o dismantling divided into 5 dismantling stages

Eort o separation divided into 5 stages

Are there hazardous building materials or materials that need to

be declared that require special disposal?

Can these materials be easily separated, and is a separated

disposal possible?

Can a veriable recycling-/disposal concept be attached to the

request or certication? What is the potential urther path o the vast majority (mass) o

the construction components?

Criterion 42: Ease o Deconstruction, Recycling,

and Dismantling

J GoalGoal o increasing the ease o deconstruction, recycling, and

dismantling is the avoidance o waste, in particular by reducing its

amount and hazard. 50% o the waste in Germany can be assigned

to the building sector. The amount o accumulated waste is to bereduced, and is to be led into recycling system. Due to the compara-

tively long expected useul lietime, many o the materials that are

used today will not accumulate as deconstruction material or poten-

tial waste until 50 or 100 years ater construction. These materials

can serve as important resources or uture construction materials.

The ability to recapture homogenous deconstruction materials and

extract high-grade recycling materials is very important or the

evaluation o ease o deconstruction and ease o recycling.

are essential preconditions or realizing sustainable buildings. This

necessitates enhanced coordination between all participants. Inte-

gral planning encompasses the entire liecycle o a building; it starts

with the project design and ends with the buildings demolition.

An interdisciplinary design team, together with the owner, develops

an integral concept with a comprehensive strategy that is oriented

toward sustainability, in order to, via high-quality planning, reduce

energy consumption and environmental pollution, and at the sametime to improve the level o comort and be economical.

J Methodology1. An interdisciplinary design team covers the most important

disciplines o the project. This generally includes at least the

categories design, structural, technical building equipment, and

building physics. For contest and the work phases 1 to 5 (HOAI

15), the involvement o interdisciplinary design teams has to be

veried.

2. Integral planning process: All targeted certication criteria are tobe integrated into the planning. Their successul integration is to

be presented through a short description o the results or each

work-phase starting rom the concept design through the nal

design and site supervision (HOAI 15, WPH 2 to 5 and WPH 8).

3. Did participation, consultative involvement, and a co-determi-

nation o the users take place? The inclusion o the uture users

into the design normally increases their acceptance and satisac-

tion.

4. Was the public involved, were they inormed and consulted, and

could they participate? An increased public participation canbe an important contribution to higher acceptance o decisions,

balanced solution, better quality decisions, ewer conficts, and

more identication o the population with its living and social

environment.

Criterion 43: Quality o the Projects Preparation

J GoalThe tasks that should be achieved prior o work phase 1 o the Ger-

man ee structure or architects and engineers (HOAI = in german:

Honorarordnung r Architekten und Ingenieure), should optimally

prepare the project. To be considered are: planning o the needs,

discussion to identiy the objective, agreement on an objective,preparation o the architectural contest, and exerting infuence

over the energy input caused by the user and the usage. Especially

the agreed upon objective is an essential element o a high quality

project preparation.

J MethodologyThe ollowing aspects will be veried and evaluated using a checklist:

1. Does quality-oriented planning or the needs exist?

2. Was a discussion to identiy the objective conducted?3. Was an agreement on an objective reached?

4. Was an architectural or design contest with special consideration

or Sustainable Building prepared?

5. Was user behaviour and user equipment considered during the

simulation, and was goal-oriented infuence over the energy

needs o the user and the usage exerted during planning and

consultations?

Criterion 44: Integral Planning

J GoalThe principles o integral planning are to be put into practice. Im-

proving the quality o planning and optimizing the planning process

Criterion 46: Evidence o Sustainability during Bid

Invitation and Awarding

J Goal

The oundation or a high-quality construction execution is laid

during the bid invitation and awarding phases. During these phases,

specic, manageable, and veriable requirements or products and

technologies or reaching the sustainability targets shall be ormu-lated. A contribution to the unctionality and quality o the building

structure with simultaneous minimization o risks and impacts on

the environmental and health shall be achieved.

The integration o sustainability aspects into the bid invitations

serves to raise the ecological and social quality o the building

by preventing the decisions on product quality rom being made

exclusively on economical viewpoints.

The integration o the sustainability aspects during the selection

o companies serves to raise the economical and social quality othe building.

J MethodologyThe ollowing aspects will be veried and evaluated using a check-

list:

1. Integration o sustainability aspects into the bid invitation: The

inclusion o sustainability aspects in the bid invitation will be

veried. For this, relevant experts o the announcement are to be

presented.2. Integration o sustainability aspects during the selection o

companies: It will be veried i the selection o the construction

rms was based on sustainability aspects, and which aspects o

sustainability were incorporated into the selection during award.

Criterion 45: Optimization and Complexity o the

Approach to Planning

J GoalThe necessary complexity o the approach to a design task shall

be secured by a minimum number and quality o concepts that are

to be generated. At the same time, the comparison o alternatives

shall be perormed with a heightened emphasis on economicaland ecological aspects as well as encouraging an external quality

assurance during planning. Normally, those aspects are dealt with

that must be worked on and veried during planning anyhow. By

developing a comprehensive concept, the quality and traceability

will be increased. The common and partially required German saety

regulations are o a high standard, which should, especially in the

international context, be emphasized.

J MethodologyThe availability, extent, and quality o the ollowing concepts anddocumentation will be veried and evaluated; as also, the type and

scope o the implemented alternative comparisons will be judged:

1. Health and Saety Plan

2. Energy Concept

3. Water Concept

4. Waste Concept

5. Measurement Concept

6. Concept or supporting the abilities o alteration, revitalization,

and recycling7. Concept or assurance or ease o cleaning and maintenance

8. Verication o the design documentation by independent third

party beyond the legal requirements

9. Comparison o alternatives

J MethodologyThe presence and quality o the ollowing documentation will be

veried:

1. Building documentation / building certication

2. Instructions or maintenance, inspections, operation, and care

3. Update o the drawings and calculations with the realized build-

ing4. Users guide

Criterion 48: Construction Site / Construction

Process

J GoalThe eects on the environment are to be minimized while simulta-

neously protecting the health o all participants. The evaluation o

the construction site and construction process includes ollowingcriteria:

1. The low-waste construction site: When buildings are constructed,

altered, or demolished, rubbish, excavated soil, letover materi-

als, packing materials, old wood, etc. accumulate. This waste is

to be avoided or salvaged. Waste that is neither avoidable nor

salvageable should be ecologically disposed.

2. Low-noise construction site: Permanent exposure to noise can

lead to overstimulation o the nervous-system and, thereby, to

health problems. In densely built areas, construction noise, atertrac noise, is the most signicant noise source. Thereore, it is

to be demonstrated that the construction noise does not exceed

the general noise level, or that adequate measures are used to

reduce it.

Criterion 47: Establishing Preconditions or an Op-

timized Use and Operation

J Goal1. The issue o a building certicate and property documentation

should provide more market transparency and a unied basis o

inormation. The property documentation, which accompanies

the building during its entire lie time cycle, supports the proc-esses o controlling and continuous improvements during the

utilisation phase.

2. Creating and documenting comprehensive instructions or main-

tenance, inspection, operation, and care can make an important

contribution to an ecient operation o the building, and thus

reduce its lie-cycle costs. The documentation should ensure that

all preconditions are met to guarantee high-quality unctionality

and a long lie expectancy.

3. Detailed design documentation and calculations o the building

that match the actual building conditions are an important basisor the management and later maintenance, reurbishment, or

renovation works o the building. These are vital or the long-

term smooth and lasting operation o the building.

4. Creating a users guide provides specic and relevant inorma-

tion to a range o users in the areas work-, utilization, and

responsibility. The purpose o a users guide is, among other

things, to explain the interrelationships o the various technical

building systems, as well as explain the special characteristics o

individual building parts and components.

Criterion 49: Quality o the Executing Contractors/

Pre-Qualication

J GoalCompetence and quality o the executing contractors shall be

described and valued. An appropriate instrument or the verication

o these qualities is the pre-qualication o the perorming contrac-

tors. In practice, additional in-house quality controls and evaluationsare applied. By being registered in the pre-qualication list, the

contractors document their reliability, technical qualication, and

capability with a kind o quality certicate to the awarding author-

ity. Pre-qualication (PQ-Procedure) is a preceding, assignment-

independent verication o suitability. The pre-qualication covers

the complete perormance chain up to the implementation o the

subcontractors. Companies can avoid the disqualication o their

proposals or ormal reasons due to incomplete or outdated suit-

ability verication, and they optimize their chances o participating

in limited announcements and negotiations. By awarding the con-tract to a PQ-certied contractor, the contracting agency can reduce

the potential risks, like insolvency o a participating contractor.

J Methodology

Veriy to which extend the pre-qualication (according to 8

VOB/A, the German construction contract procedures) was consid-

ered during contract award.
