The Role of Codes in Sustainable Development To: National Association of Counties On: Feb 3, 2011 Jeremy Sigmon Mgr. Building Codes Advocacy U.S. Green Building Council jsigmon@usgbc.org
A Very Brief History of Building Codes ~3,000 B.C.E. – Ancient Babylon 64 C.E. – Roman Empire 1842 C.E. – England 1871 & 1906 C.E. – Chicago & San Francisco
2006 International Building Code 101.3 The purpose of this code is to establish the minimum requirements to safeguard the public health, safety and general welfare through structural strength, means of egress facilities, stability, sanitation, adequate light and ventilation, energy conservation, and safety to life and property from fire and other hazards attributed to the built environment and to provide safety to fire fighters and emergency responders during emergency operations.

Number of LEED Green Building Policies Adopted in U.S. Cities and Counties by Year 450 Number of Local LEED Policies 400 350 300 250 200 150 100 50 0 Before 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2000 Year New Local LEED Policies Cumulative Policies from Previous Years As of September, 2010.
A long road ahead…
On the road to sustainability… Voluntary, beyond-code rating systems pull by fostering leadership • Leadership by example • Incentives for beyond-code leadership 3 concurrent policy pathways • Mandatory minimums Better building codes raise the floor for all buildings

International Green Construction Code Dennis A. Andrejko, FAIA AIA National Vice President M ember of the ICC Sustainable Building Technology Committee Benefits of IGCC NACo Building Sustainable Communities February 3, 2011
• Buildings consume about 40 percent of U.S. energy & about same amount of U.S. carbon emissions • 76 percent of all electricity generated from nonrenewable sources consumed by buildings • Status quo = 35% increase in energy consumption & GHG emissions by 2030 Why is a Green Code Needed?
• AIA goal: carbon neutrality in built environment by 2030 • “Green” code book guides construction and design activities just like other I-Codes
“Green” building driven into everyday practice Safer, more energy- efficient buildings
– Buildings can be designed to operate with significantly less than today’s average energy levels -- often with little/ no additional cost – For measurable progress to be made, a regulatory framework is needed – only achievable through code
Like all other I-Codes, IGCC will be “model” code, requiring adoption by governing jurisdiction before it becomes law
IGCC as overlay code Coordinates & integrates with existing I-Codes No separate green permits
One of the values of the IgCC is that it is designed to coordinate and integrate with the existing I-Codes. The IgCC offers various tiers of jurisdiction to apply to commercial and high performance buildings. In a manner that incorporates the heath and safety features of the other I-Codes. What is an Overlay Code ?
• M inimum & advanced levels of performance – Performance & prescriptive options • ASHRAE 189.1 is also compliance option – Local adoption process • Adopting IGCC with 189.1 – Allows widest set of options • Offers M ethods for measuring compliance
Chapter 1: Administration Chapter 2: Definitions Chapter 3: J urisdictional Requirements & Project Electives Chapter 4: Site Development & Land Use Chapter 5: M aterial Resource Conservation & Efficiency Chapter 6: Energy Conservation, Efficiency & Atmospheric Quality Chapter 7: Water Resource Conservation & Efficiency Chapter 8: Indoor Environmental Quality & Comfort Chapter 9: Commissioning, Operation & M aintenance Chapter 10: Existing Buildings Chapter 11: Existing Building Site Development Appendix A: Optional Ordinance Appendix B: Greenhouse Gas Reductions In Existing Buildings Appendix C: Sustainability M easures Content
• State & local governments need credible, enforceable, & adoptable code in place • IGCC is product of consensus-driven process
• Easily customizable • Read, administered like other codes & will utilize same distribution, training, permitting, & enforcement procedures already in place
• IGCC in development (currently on Public Version 2.0) – Set for early 2012 publication • U.S. Conference of M ayors endorsed IGCC last summer • Oregon using PV 2.0 as base document for its new “Reach” Code
• The AIA, its 200+ state & local chapters (“components”), & its members are committed to the IGCC because we are committed to decreasing energy use & the impact of new and existing buildings on the environment. • They are valuable resources to which you and your building departments can turn in the development of enforceable, usable, and sustainable building codes and standards.
