NORTHEAST ENERGY EFFICIENCY PARTNERSHIPS Accelerat ing Energy Eff iciency

1

MISSION

Accelerate the efficient use of energy in the Northeastand Mid-Atlantic Regions

APPROACH

Overcome barriers to efficiency through

Collaborat ion, Educat ion & Advocacy

VISION

Transform the way we think aboutand use energy in the world around us.

WHERE THAT ENERGY GOES

- 2010 Buildings Energy Data Book, Building Technologies Program, Office of Energy Efficiency and Renewable

Energy, U.S. Department of Energy, November 2010.

WHY ARENT BUILDINGS MORE EFFICIENT?

Missed Opportunities SEE Action Network Blueprint for Energy Efficiency

Follow on to National Action Plan for Energy Efficiency

Includes RTOs, utilities, real estate, governmentorganizations, NGOs

Based goals on McKinsey 09 estimate of ~ 2.275 quadsof cost-effective energy efficiency potential incommercial buildings

Four Priority Solution Pillars

o Dr ive Demand for Energy Eff iciency

o Enable Efficient Operations and Investment

o Build the Workforce

o Move the Market

WHY ARENT BUILDINGS MORE EFFICIENT?

New construction Split incentives (landlord/tenant)

Lack of information/understanding

Code compliance

One solution: better code development, adoption,compliance processes Net Zero Energy Buildings

Existing buildings/retrofits Split incentives (landlord/tenant)

Tenant turnover Lack of information/understanding - discounting energysavings

Financing

One solution: building energy rating& disclosureOne solution: equipment efficiency standards 6

MANAGING OUR BUILDING ENERGY USE

New construction: Building energy codes

Development

Adoption

Compliance

High performance building standards

Stretch codes

Zero Net Energy Buildings

Existing buildings/retrofits Financing

Building energy rating

Appliance/equipment efficiency standards

9/27


Building energy codes Cover for residential & commercial, the buildingshell, its systems and built-in equipment:

Building Envelope

Mechanical

Service Water Heating

Lighting

Electrical Power Set minimum requirements for energy-

efficient design in new construction andsubstantial renovation

10/27


Building energy codes Building codes are a long established practice

Code of Hammurabi (3000 B.C.) establishedbuilder liability for a home that collapsed

Established in U.S. in late 19th and early 20th

century, demanded by insurance industry

Designed to protect public health, safety and

general welfare Energy added in mid-1970s to address generalwelfare of energy crisis

EXAMPLES OF CODE REQUIREMENTS

The energy code specifies theinsulation levels in the floor,

ceiling, and walls and

requirements intended to sealthe building against air leakage

and moisture migration.

10


12/27


Energy codes provide

criteria for thesize and efficiency of HVACsystems and equipment.

11


13/27


The energy codes provideminimum criteria to support

efficient, effective lightingand in commercial spaceslighting controls.

14/27


Building energy codes Development -

National model code bodies ICC, ASHRAE

Updated every three years currently IECC 2012 &ASHRAE 90.1-2010

Tied to DOE stated goal of net zero buildings by 2030

Adoption -

On state-by-state basis

o

Legislative Can include automatic update provision

o Administrative

Some 12 states w/o mandatory C or R energy code

ARRA funding tied to IECC 2009/ASHRAE 2007 adoption13


15/27


Building energy codes Compliance -

Generally by local building officials

Part of overall building code enforcement

Should be verified for compliance prior to issuing CO

Issues of:

o Time/resources

o Knowledge/understanding

o Priority: often falls behind health/safety codes

o Accountability

ARRA funding tied to commitment to 90 % complianceby 2018

14


16/27


Building energy efficiency Shaheen-Portman Energy Savings and IndustrialCompetitiveness Act of 2011

Codifies DOE goal-setting and certification practices

re: building energy code development Requires DOE to support state energy code trainingand education

Requires states to certify energy code updates and

compliance plans

Must also certify whether achieved 90 % compliance

If not, state must submit status report to DOE

Conformance may be required by DOE as a criterion

for grants or other support

15


17/27


Existing buildings/retrofits Issues/obstacles -

Split incentives (landlord/tenant)

Tenant turnover

Lack of information/understanding

Discounting energy savings

Financing

One solution: building energy rating& disclosure

16


18/27

BUILDING ENERGY RATING/DISCLOSURE

17


19/27

BUILDING ENERGY RATING/DISCLOSURE

18

Building rating or label Scorecard of home or buildings relative energy performance

Technical scale of performance

Experience in EU, Australia, several U.S. municipalities

Disclosure to consumers

Provide label/rating/information to buyers/renters

Disclose early enough to impact sales/rentals

Both residential and consumer

Analogous to product Energy Guides, but for properties

Allow markets to drive energy efficiency retrofits

Properties become valued for higher energy performance

Prompt upgrades before properties go to market

Allow energy performance to be negotiated into price


20/27


Home/Building Energy Rating & Disclosure Waxman-Markey (09) required DOE to establish modelhome/building rating model & would provide federal $ tostates if they mandated based on those models

White House CEQ/Recovery Through Retrofit IDs homerating as key to retrofit

DOE began developing in 10, pilot tested in 10 states

Program refinement/next phase announced Sept. 11

Similar effort soon to launch for commercial RFI will seek comments/input to commercial tool

Several important questions to be addressed:

o Site vs. source energy?

o

Asset or operational rating, or both?o Frequency? 19

RESIDENTIAL NOW, COMMERCIAL TO COME

22/27


Building Energy Rating & Disclosure Many good models to work with/from:

o International:

o European Union

o Australian Capital Territory

o US:

o California Assembly Bill 1103

o DC Clean and Affordable Energy Act (2008)

o NYC Greener, Greater Buildings Plan

o San Francisco Existing Commercial Buildings EnergyPerformance Ordinance

IN THE MEANTIME

What about commercial building benchmarking? In April, EIAs FY 2011 funding cut by $15.2 million,hitting energy data, analysis and forecasting

Resulted in suspension of 2011 Commercial Buildings

Energy Consumption Survey (CBECS) - only source ofstatistical data on energy use/characteristics ofcommercial buildings

Also basis for ENERGY STAR Portfolio Manager

National Institute for Building Science (NIBS) proposingHigh-Performance Building Data Collection Initiative

o Hearing July 18 on data needs, existing sources
