Overview
1) Why buildings?2) New Buildings3) Existing Buildings3) Existing Buildings4) Cross-Cutting Strategies
Commercial Building Energy: Fastest Growth
Percent Change, 2010 to 2030
Elements of a Zero-Energy Buildings Strategy
� Research and Development – Create new technology- RD&D Partnerships with Industry
� Incentives & voluntary programs – Create buyer demand- Tax incentives, rebates, loan guarantees, etc.- Utility programs (DSM, Demand Response, REPS/EEPS)- Utility programs (DSM, Demand Response, REPS/EEPS)
� Public Education – Build market share- Consumer education and awareness campaigns- Energy labels (equipment and buildings)
� Standards – Set a floor & trigger innovation- Appliance standards, building codes, vehicles- Utility Energy Efficiency Resource Standards (EERS)
� Public sector leadership – Reduce market risk� Workforce development – Capacity building
Setting a Long-term Goal: “Net-Zero” Energy
Defining NZE: A building that is designed, constructed, and operated: operated: - To greatly reduce energy use (i.e. ~80%)-…and meet remaining energy needs from
renewable sources- Carbon-neutral- Economically viable (net-zero cash flow)
Changing Policy Landscape for NZE Buildings
� Architecture2030, Cool Mayors, AIA “commitment”� ASHRAE Std 90.1, Std 189, Advanced Guides� NAHB Green Standard & ICC Green Code� California AB 32 & Strategic Plan� California AB 32 & Strategic Plan� Federal goals for NZE- Existing & new buildings- Zero Energy Commercial Buildings Initiative
� 2007 EISA, 2008 tax credit extensions, 2009 ARRA� Next: ACES, ACELA, ECJAPA… – and EPA
regulation of GHGs (?)
Commercial Sector –Where Are We Today?

Driving Efficiency through Building Energy Codes
� Federal legislation pending- 30% improvement in model energy codes by 2010- 50% before 2020
� 2009 IECC Model Energy Code for Homes:-- ~13% efficiency improvement over 2006- Remainder of 30%+ goal in 2012 code cycle
� ASHRAE 2010 Goal (Commercial): 30% by 2010� Cumulative savings thru 2020: 4 quads (1015
Btu); ~230 million tons CO2
Multi-Level Alliance Strategy for Energy Codes
1) Code Advancement- EECC advocates for stronger Model Energy
Code- BEECN pursues legislation for national code - BEECN pursues legislation for national code
targets and funding
2) Code Adoption- BCAP & RECA pursue state by state action
3) Code Implementation (compliance)- BCAP technical support for statewide
planning & implementation
Potential Savings from Codes
� By 2030 our nation could save each year:� 8% of total building energy use� $28 billion a year in consumer energy bills
CO emissions of 46 million autos� CO2 emissions of 46 million autos
New Codes Paradigm: 1) “Dynamic” Codes

Use
1) Make regular code advancement the norm (create market expectation of continuous improvement)

2) Prepare market for the next step:� Training� Incentives� Recognition
New Codes Paradigm: 2) “Technology-Ready”
� Current approach: -We make decisions on a 30-50+ year asset
based on ~5 year economics (builder or first owner)owner)- Codes represent the low end of the “Valley of
Economic Indifference”
� New approach:- Pay most attention to most permanent feature-Where feasible, build in “technology-readiness”
Existing Buildings: No Silver Bullets!
� “Deep” retrofits vs “opportunistic upgrades”� Innovative financing (PACE, utility-bill
financing, neighborhood targeting, etc.)financing, neighborhood targeting, etc.)� Energy management as a process not an
event (Retro-Cx, operator training, etc.)� Feedback, benchmarking, energy rating &
disclosure
Building Energy Rating and Disclosure
� Goals: -Make energy performance visible to the market- Capitalize (securitize) future $ savings
� Labeling approach:-
� Labeling approach:- Technically valid – and perceived as valid- Empirical – based on available data (or “default”)- Practical – consider cost vs value of information- Target key decisions (decision-makers) :
� Asset rating (buy/sell/rent/finance)� Operational rating (manage, retrofit)� Main EE features (all)
- Universal (mandatory not voluntary)
Building Energy Performance: Labels, Labels, Everywhere!

Putting It All Together: Zero Energy Commercial Buildings Initiative
� Authorized in EISA (12/07)� Net-zero commercial building goals- 2030: New construction- 2050: Entire stock
Broad government/industry consortium� Broad government/industry consortium� Comprehensive approach (R&D deployment)� Coordinate (initiate) national and local actions- Measure, benchmark, disclose energy performance- R&D for critical technologies and systems - Demo’s: scalable, replicable system solutions- Transform market: Education/training, finance,
appraisal, incentives, codes, buyer demand-pull
Leveraging Financial Resources
Retrofit
Construction Bid Range: 5-15%
“Waste” in Industry: 10-30%
Cost of “green”: 0-5%
Cost of ZEB: 0-20%

Thinking “Outside the [Building] Envelope…”
� Locational efficiency- Transit-Mixed-use
Grid integration (“net-zero energy” � Grid integration (“net-zero energy” framework is incomplete)- Smart grids-Microgrids
� Rediscover district heat/cooling� Managing potable water (“use cascading”)
