DESCRIPTION

Vice President for Programs Jeff Harris (jharris@ase.org) discussed energy efficiency measures in new and existing buildings, as well as cross-cutting techniques for achieving maximum advantages. Jeff’s work focuses on U.S. and international energy efficiency policies for buildings, appliances, and utilities, and market transformation through public sector leadership.

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 (?)

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”)
