Sustainability Mandates for Federal Facilities

- Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings

Primary area of FEMP Focus




What's the best way to achieve

High-Performance FederalBuildings?

• There is no single technology, rating

system, or magic bullet that achieves high

performance buildings.

• Integrated design, building information

modeling, and building performance data

are some examples of current tools used

to ensure the successful constructions

and operations of high-performance

buildings.

• Retrofits/Renovations are CRITICAL for Agencies to focus on when attempting to

meet Federal Goals

Importance of collecting Building Performance Data for Exist ing Facilities

Effective O&M is one of the most cost-effective methods for ensuring reliability, safety, and energy efficiency. Properly performedO&M can;

• ensure optimum equipment performance and efficiency

• extend life expectancy of equipment

• reduce/eliminate early equipment failure

• mitigate energy waste due to inadequate maintenance

However NO type of effective O&M can be undertaken without consistent and quality data!

Importance of Building PerformanceData

Agency & Facilities Functions – 4 aspects of required Federal data col lection

The Federal reporting requirements require Agencies to report on a multitude different aspects of their dailyoperations and energy use, not just at the facility level.

To help Agencies understand the requirements, these reporting data needs can essentially be generalized

into four sections; Agency Aggregate Data, Agency Operations Data, Individual Bui ld ing Data, andSpecific Project Data.

Metering



The success of achieving the goals and mandates are dependent on numerous s trategies, including• Proper integrated design,

• quality building re/retro-commissioning,

• proper goal setting/benchmarking,

• verification that systems are operating as designed,

• institutional operations

However one of the most crucial items to focus on are the Agency O+Mprotocols:

• Do the facility managers have protocols for checking automatic controls?

• Do they know when those controls are malfunctioning?

• Do they know how their buildings are running?

• How much is meter data is being collected currently or analyzed? Would additional

metering improve anything?

• Is the data being collected ACTUALLY being used to verify building operations andupgrades?

• Are all mechanisms/programs to obtain energy efficiency equipment being used?

• Are the benchmarking goals being performed with management input and oversight?

KEY O&M POINTS


*per EPAct 2005 Section 103

94.2% of appropriate Federal Buildings* have electric meters installed. The focus now should be onoptimum use of that data!



What is the difference between the types of regulations?

Perspective on Federal Mandates

• EXAMPLE – By 2015, reduced energy intensity by 30%as compared with the energy consumption per grosssquare foot of the Federal buildings of the agency infiscal year 2003.

Outcome Based Requirements

• EXAMPLE – All new construction, major renovation orrepair and alteration of Federal buildings are to compile

with the Guiding Principles.

Design Standards Requirements

• EXAMPLE – Require 95% of new contrac ts act ions toinclude products and services that includeenergy/environmental product specifications

Prescriptive Process Requirements

EXAMPLES

The key to effective legislation is

to set a target and then allow Agencies to achieve that targetthrough “ best practices” thatare most effective andappropriate for that Agency

Review of Federal Sustainabili ty Mandates – Energy/Water


18/18Federal Energy Management Program femp energy gov 18

Executive Order 13563, Improving Regulation and Regulatory Review

Section 3

- Calls on Agencies “to reduce burdens, redundancy, and conflict, and at the same time to promote

predictability, certainty, and innovation.”

Proposed FEMP 3-point legislative litmus test

1. Mandates/requirements should be goal oriented, non-

prescriptive, nor should they overlap or unintentionally conflict

with current requirements.

2. Legislation should mandate reporting protocols that ensure that

only practical, reliable and useable data is collected and

reported

3. The legislative language should place an emphasis on

processes that ensure that the proposed targets and goals can

be maintained in the future.
