22@ SUSTAINABILITY GUIDE4

APPROACH

In our visits both the 22@ and Eixample, we observed a very stark difference in the character of the public realm.

APPROACH

INTERPRETING THE DISTRICT PLANNING

APPROACH

INTERPRETING THE DISTRICT PLANNING

APPROACH

For passive solar heating face most of the glass area south to maximize winter sun exposure, but design overhangs to fully shade in summer.

GENERATING SUSTAINABILITY STRATEGIES

APPROACH

Trees (neither conifer or deciduous) should not be planted in front of passive solar windows, but are fine beyond 45 degrees from each corner.

Do Not Violate Solar Access

45’ 45’

APPROACH

Good natural ventilation can reduce or eliminate air conditioning in warm weather, if windows are well shaded and oriented to prevailing breezes.

APPROACH

Keep the building small, because excessive floor area wastes heating and cooling energy.

APPROACH

Sunny wind- protected outdoor spaces can extend living areas in cool weather (seasonal sun rooms, enclosed patios, courtyards, or verandahs)

GOALSDefining the goals of the sustainability guide.

GOALS1. Strengthen the connection between 22@ district and Eixample2. Foster Social Equity3. Encourage a variety of economic activity, with a focus on technology, design, and

research4. Minimize the environmental impact, both of development and operation

Encourage walkability within the district of 22@, and require an active focus on the public realm design within the district.

STRENGTHEN THE CONNECTION BETWEEN 22@ DISTRICT AND EIXAMPLE

Encourage mixed-use development, both horizontally and vertically.

Social Housing

FacilitiesCommercial

Market Residential

OfficeHotel

Encourage smaller scale development with a focus on buildings forming a strong street wall.

FOSTER SOCIAL EQUITY

Encourage a mixing of incomes of the residents of 22@.

Enhance the benefit of the 7@ uses to the community.

Create employment opportunities for residents.

ENCOURAGE A VARIETY OF ECONOMIC ACTIVITY, WITH A FOCUS ON TECHNOLOGY, DESIGN, AND RESEARCH Preserve the small scale character of existing commercial.

ENCOURAGE A VARIETY OF ECONOMIC ACTIVITY, WITH A FOCUS ON TECHNOLOGY, DESIGN, AND RESEARCH Allow large companies the ability to develop offices not suitable elsewhere.

MINIMIZE THE ENVIRONMENTAL IMPACT, BOTH OF DEVELOPMENT AND OPERATION

Encourage reuse of water from captured precipitation.

Encourage passive design strategies and relying on renewable forms as a major energy source.

Induce a successful material economy that is non-toxic, transparent, socially and environmentally equitable.

ANALYTICALSCENARIOSThree study models to analyze the existing conditions.

ANALYTICAL SCENARIOS

URBAN REGULATIONS STUDY AREA

ANALYTICAL STUDY MODELS

Public Realm Model: The public realm model aims to continue the Eixample character into the 22@ district and generate a vibrant mix of uses that enhances the neighborhood character of the district.

Preservation Model: This model aims to preserve the small scale character of the existing 22@ parcels and generate diversity in the uses for the district.

Passive Strategy Model: The strategy aims to maximize solar gain and minimizing shadows on respective blocks.

‘PUBLIC REALM’ STUDY MODEL

◦ Formal coherence and focus on the public realm

◦ Optimization of street wall definition ◦ Optimize walkability

‘PRESERVATION’ STUDY MODEL

◦ Focus on preservation and mixed-use ◦ Emphasis on diversity of scale ◦ Development following existing parcel

structure

‘PASSIVE STRATEGY’ STUDY MODEL

◦ Optimization of passive strategies and focus on large scale uses

‘PASSIVE STRATEGY’ STUDY MODEL

◦ Optimization of passive strategies and focus on large scale uses

Public Realm Model:The public realm model focuses on a public space oriented design that maximizes the street wall definition and generates a walkable neighborhood.

Preservation Model:Focus on mixed-use character with an emphasis on the diversity of uses aimed at supporting small scale businesses that can draw a varied social scale of users.

Passive Strategy Model:A solar envelope from 9 am to 3 pm preserves the availability of light in each of the blocks.

CRITIQUESCritique of the existing zoning regulations and bylaws.

CRITIQUES

THE BARCELONA 22@ DISTRICT IS CURRENTLY IN A STATE OF RAPID TRANSITION REGULATED BY THE BLOCK BASED URBAN RULES

CRITIQUES

PRESERVATION

CRITIQUES

NO DISTRICT PRESERVATION

Preservation towards individual buildings rather than district character.

CRITIQUES

“The minimum area of transformation action, regarding the application of the regulations, is 60% of the range of the planning.”

Threshold of ownership at 60% and lack of an incentive for preservation tends to encourage demolition of entire blocks.

CRITIQUES

Threshold for transformation requires large scale parcel consolidation resulting to a loss of diversity in scale of development, ownership and economic activity.

CRITIQUES

SCALE OF DEVELOPMENT

CRITIQUES

RULES ENCOURAGE LARGE SCALE DEVELOPMENTS

Scale of buildings create a disconnected neighborhood.

CRITIQUES

RULES ENCOURAGE LARGE SCALE DEVELOPMENTS

Demolition leading to a loss of small scale affordable spaces.

CRITIQUES

MIXING OF USES

CRITIQUES

Rules allow, and in some cases mandate, single use buildings.

DEVELOPMENT IS NOT MIXED USE ENOUGH

“Assignment of plot ratio of 0.3 sq.m gross floor area/sq.m land for social housing.”

CRITIQUES

The method of open space requirement for market rate housing discourages their construction. It encourages tower forms by requiring open space as density increases.

“Assignment of 31 square meters of land per each 100 square meters of residential gross floor area, 18 square meters would be for green zones.”

LACK OF DEFINITION AND ACTIVITY IN THE PUBLIC REALM

CRITIQUES

Rules lead to large single uses on the public frontage.

Concession of an area of land equivalent to 10% of the scope of the project, destined to community amenities.

RECOMMENDATIONSProposal for 22@ Sustainability guidelines.

RECOMMENDATIONS

DEVELOP PLAN THAT RELATES BUILDING TO THE DISTRICT PUBLIC REALM & OPEN SPACE

RECOMMENDATIONS

The current open space plan that has been created for 22@ is not being followed in the execution of development.

RECOMMENDATIONS

The current open space plan that has been created for 22@ is not being followed in the execution of development.

RECOMMENDATIONS

PRESERVATION AT VARYING SCALES

RECOMMENDATIONS

INCENTIVIZE PRESERVATION AT VARYING SCALES

Encourage preserving district’s architectural character and scale of ownership through reuse. Consider creating a process for transfer of development rights allowing unused FAR on historic properties to be permanently sold and built on parcels on adjacent blocks.

RECOMMENDATIONS

INCENTIVIZE PRESERVATION AT VARYING SCALES

Reduce requirement for the FAR bonus from 100% to 75% of the block to preserve existing buildings.

RECOMMENDATIONS

SMALLER SCALE DEVELOPMENT

RECOMMENDATIONS

Recommend buildings use vertical articulation to break up perceived scale of development.

CONSTRAIN DEVELOPMENTS TO A SMALLER SCALE

RECOMMENDATIONS

Standardize a minimum functional entry space every 9 meters for mixed use developments and 22 meters for non-mixed use developments.

Mixed use

Non-mixed use

RECOMMENDATIONS

Require 50% of the building mass to be under 12 meters.

RECOMMENDATIONS

MIXED USE DEVELOPMENT

RECOMMENDATIONS

ENCOURAGE MIXED USE DEVELOPMENT BOTH HORIZONTALLY AND VERTICALLY

Remove the 10% footprint requirement for social housing and instead require it in the form of 0.1 FAR.

RECOMMENDATIONS

Require 25% open space by block, replacing the 10% public open space requirement.

RECOMMENDATIONS

Implement a minimum ground floor retail frontage of 35%.

RECOMMENDATIONS

ACTIVE PUBLIC REALM

RECOMMENDATIONS

IMPROVE THE DEFINITION AND ACTIVITY OF THE PUBLIC REALM

Replace 10% footprint requirement with an FAR requirement for 7@ uses.

RECOMMENDATIONS

Enforce a minimum building perimeter height of 9 meters.

RECOMMENDATIONS

Constrain all openings, vehicular entrances, and open spaces to 28 meters along the perimeter from the corner of the block.

28m 28m

RECOMMENDATIONS

Require 60% ground floor transparency.

RECOMMENDATIONS

ENVIRONMENTAL SUSTAINABILITY METRICS

RECOMMENDATIONS

CREATE AN ENVIRONMENTAL SUSTAINABILITY METRICS

Bylaws should limit all new development from casting shadow for more than 2 hours a day on adjacent buildings.

RECOMMENDATIONS

80% of storm water generated within a block should be recycled.

RECOMMENDATIONS

80% of the open space within the block should have porous paved/unpaved surface.
