Standard 189.1: A Pathway to Achieving Emissions Reductions Goals Lawrence J. Schoen, P.E. June 15, 2016 Congressional Briefing High Performance Building Coalition How ASHRAE Standards Can Meet State and Local Demand for High Performance Green Buildings Schoen Engineering Inc., Columbia, MD 410-730-9797; Larry@SchoenEngineering.com

Standard for the Design of High Performance Green Buildings Timeline of Standard 189.1 Standard for the Design of High Performance Green Buildings 2006: Development started 2009: First version published 2011: Revision published 2012: IgCC Published: 189.1 is compliance option 2014: Revision published 2017: Revision forthcoming

International Green Construction Code IgCC and Standard 189.1 Standard 189.1-2017 re-write in progress 189.1 to be technical core of IgCC and LEED Same ASHRAE Committee has charge Added more members with code experience ICC will develop administrative and enforcement structure Comparing 189.1 and IgCC to identify opportunities to improve standard

Environmental impacts of buildings U.S. buildings impact as a % of Total Economy Other impacts: site biodiversity; rainwater management; environmental emissions; construction materials and waste

Standard 189.1 “101”: Co-Sponsors ASHRAE + ICC IES USGBC

189.1 Builds on Other ASHRAE Standards 62.1 90.1 55 170

Summary of 189.1 Site provisions to reduce landscape impact, urban heat island, light pollution and storm water runoff Water-use provisions to reduce unnecessary water use Energy-use and efficiency provisions to reduce energy use, emissions and peak demand IEQ provisions to help keep building occupants comfortable, healthy and productive Materials provisions to reduce impact on resources as well as earth and atmosphere (reduce, reuse, recycle) Construction and plans for operation to help the HPGB operate as intended by design team

Standard 189.1: Purpose and Scope Siting, design, construction & plan for operation Support development that meets needs of present without compromising ability of future generations to meet their needs. SCOPE: New buildings; new systems and equipment in existing buildings Commercial, institutional and high-rise residential buildings Purpose and Scope in revision process

Section 4: Administration and Enforcement Each section, except 5 (Site) and 10 (Construction and Plans for Operation), organized as follows: #.3 Mandatory requirements #.4 Prescriptive requirements #.5 Performance requirements OR Can do Prescriptive or Performance section-by-section, e.g., prescriptive for water but performance for energy

Federal Preemption: Efficiency Standards Municipalities may not exceed federal Federal Court voided 2007 Albuquerque code that mandated more stringent efficiencies Manufacturer trade group (AHRI) “gratified” ASHRAE does not have a position Local and state governments may enact market based incentives instead of mandatory codes For more info, see Schatmeier, “Avoiding Albuquerque,” Columbia Journal of Environmental Law, 2012 – December 19

Section 7: Energy Efficiency 7.3 Mandatory: Prep for renewables, Measurement devices, record and store data, PLUS OR 7.4 Prescriptive: Insulation, HVAC, hot water, lighting, install renewables 7.5 Performance: Computer simulation to demonstrate energy, CO2 emissions and peak demand better than prescriptive
