Agenda: Welcome and Introductions Coleman Davis Staff, Green Government Initiative National Association of Counties (NACo) Energy Codes and Regulations: What Counties Need to Know Jayson Antonoff U.S. Director of Global Buildings Performance Network Institute for Market Transformation Energy Rating and Benchmarking Systems Jessyca Henderson Managing Director of Policy and Community Relations The American Institute of Architects (AIA) Q&A Closing Remarks 10
Energy Codes and Regulations What Counties Need to Know Jayson Antonoff U.S. Director, GBPN Institute for Market Transformation National Association of Counties September 5, 2013
Today s Session Why are energy codes and regs important to local government? Codes vs. standards Adoption process Beyond codes
What Is an Energy Code? Sets minimum requirements for the construction and renovation of building elements that effect energy consumption
Why Should State and Local Governments Care? Contribute to quality construction Help to reduce energy consumption: on average every $1 spent on energy code enforcement yields $6 in energy savings Contribute to economic growth: energy efficiency has local economic multiplier of $2.23 Your citizens expect it!
Energy Codes and Standards
IECC National model energy code CODES IgCC National model green code Locally Adopted Codes Based on national model codes with local amendments ICC 700 Green rating system for SF/MF residential buildings and sites Compliance option Compliance option for some jurisdictions STANDARDS ASHRAE Standard 90.1 Energy std for commercial and high rise residential buildings ASHRAE Standard 189.1 Green building standard written in code language Compliance option for commercial and high rise residential Compliance option Compliance option for most jurisdictions RESNET HERS Index for inspecting and calculating home energy performance Proposed compliance option Compliance option for some jurisdictions
IECC vs. ASHRAE 90.1 IECC applies Both IECC and ASHRAE 90.1 apply, either used to comply Both IECC and ASHRAE 90.1 apply, ASHRAE 90.1 likely used

Code Development Open and Public
Current ICC Development Process Code change proposals submitted Code development hearing, public testimony, committee vote Public comment period, challenges of code development hearing, proposed modifications Final Action Hearing, public testimony, final vote of government members New code published and distributed Jan 2013 Apr 2013 May 2013 Oct 2013 Spring 2014
Energy code Adoption can occur: Directly through legislative action (state level) By regulatory action through state or local agencies.

Compliance and Enforcement Ensuring that a building meets the requirements of building energy codes, is the last step in the building process. Review plans Review products, materials equipment specifications Review tests, certification reports, product listings Inspect building and its systems during construction Evaluate materials substituted in the field Inspect prior to occupancy
Barriers to Effective Code Compliance Funding Building departments often understaffed and underfunded Needs depend on volatile construction volumes (permits); difficult to rebuild capacity after construction rebounds Education Inconsistent interpretation by code officials Code officials and building professionals inadequately trained Political willingness Code officials focus on structural and life-safety issues, not energy codes
Plan review and inspection may be performed by: Code inspectors in local building dept (most traditional) Third party plan review and/or inspection Design professionals Public-Private Partnership (local gov t contracts with third-party)

Brochures for Additions, Alterations, Renovations Explains how the IECC applies to additions, alterations and renovations for: Residential Buildings Residential HVAC Residential Insulation and Air Leakage Commercial Buildings Commercial Lighting http://www.imt.org/codes/existing-buildings Can be rebranded with logo and contact info for your city or county
Going Above and Beyond Code LEED IgCC ASHRAE 189.1 Green Globes
The IgCC Goes through the standard 3-year ICC development cycle Is a venue for more advanced building practices Is designed to be an overlay on all the I-codes Green Codes and Stretch Codes Green codes are supposed to be mandatory right? Rating systems are voluntary or are they?

(Ch. 11) LEED -NC Admin. through GBCI Sustainable Sites Materials and Resources Energy and Atmosphere Water Efficiency Indoor Environmental Quality Innovation in Design LEED-NC (major renov.)
Critical Issues, Unique Features IgCC: Designed to be enforced in-house, requires new processes and coordination across departments written in language familiar to code officials, touted as a building code. LEED: Not intended to be enforced by the building department, can be 100% third party verification, jurisdiction can set threshold, progressive builders are familiar with system, doesn t always fit into the code, points code compliance
Energy Efficiency Performance LEED V3: 10% above ASHRAE 90.1 2007 LEED V4: 5% above ASHRAE 90.1 2010 (or 50% AEDG, Core Performance) ASHRAE 189.1: 10% above ASHRAE 90.1 2010 IgCC: 10% above 2012 IECC Green Globes: EPA's Target Finder
Pima County, AZ Current Green / Energy Requirements Current Requirements Home-rule state with NO state-wide energy code; codes are adopted and enforced at a local level State-funded buildings must be LEED Silver rated and meet the energy standards of ASHRAE 90.1-2004. Local requirements: 2012 IECC or ASHRAE 90.1-2010, with local amendments
Pima County, AZ Current Green / Energy Requirements Alternative Compliance Paths EnergyStar for Homes uses HERS LEED for Homes requires HERS rating 15% better than IECC 2006 (third party certified) Net-Zero Energy Building Standard Beyond Code (voluntary) Pima County Regional Residential Green Building Rating System LEED commercial and residential

AIA Evaluation Criteria Developed and renewed on a regular basis Clearly defined design documentation Independent third party verification; Development of sustainable sites Efficient use of water resources Significant reductions in energy use Renewable energy sources; Reduced use of nonrenewable natural resources
AIA Evaluation Criteria Indoor environmental quality Innovative designs and collaborative processes Life cycle value Life cycle assessment data National, regional, and bioclimatic differences; Reduces on-site and off-site toxic elements Measurable reductions in (CO 2 ) production Documentation of actual building energy
AIA Evaluation Criteria PLUS: Energy Modeling for projects over 100,000 s.f. Energy efficiency targets that meet or exceed IECC 2012 and ASHRAE 90.1 2010 Elimination of toxic chemicals in building materials Materials certified by third-party
A few things counties can do: Consider flexibility, and options (code+) Think locally, regionally on all measures & metrics Communicate efforts early, and often Connect with the design community Form a cross-functional working group to evaluate Divide and conquer based on expertise Solicit Feedback, and make it a feedback loop Engage the next generation
