Zero Energy Buildings (ZEBs) National Policy Initiatives/Activities - PowerPoint PPT Presentation

Zero Energy Buildings (ZEBs) National Policy Initiatives/Activities APGA Policy Conference March 29, 2016

Current State of Play • Minor Share of New Building Starts • Momentum is Growing at the State and National Level – CA Leading the Way • Diverse Set of Stakeholders Engaged • Objectives Vary By Type of Stakeholder 2

ZEB Distribution By Building Type 6

Common Blueprint for ZEB’s • Cost Effective, Integrated Building Designs • Highly Efficient Energy Equipment • Grid Connectivity for Exporting Renewable Power • Use of Renewable Energy Technologies to Offset Building Energy Consumption 7

DOE Zero Energy Ready Home Requirements 1. BASELINE: Certified ENERY STAR for Homes, V 3.0 2. ENVELOPE: Meets or exceeds 2012 IECC levels 3. DUCT SYSTEM: Located within the home’s thermal boundry 4. WATER EFFICIENCY: Meets or exceeds the EPA’s WaterSense S. 3.3 5. LIGHTING & APPLIANCES: ENERGY STAR qualified 6. INDOOR AIR QUALITY: Meets or exceeds EPA Indoor airPLUS Verification Checklist 7. RENEWABLE ENERGY: Meets EPA Renewable Energy ‐ Ready Home 8

But… Different Definitions for ZEBs • Net Zero Site Energy • Net Zero Source Energy • Net Zero Energy Emissions • Net Zero Energy Costs 9

DOE Proceeding ‐ Common Definition for ZEBs • Request for Information (RFI) ‐ January 6, 2015 • Proposed ZEB definition: An energy ‐ efficient building where the actual annual source energy consumption is balanced by on ‐ site renewable energy . • AGA and APGA submitted joint comments supporting source energy based definition – February 24, 2015 • Sixty ‐ five other organizations/individuals also submitted comments, many of which opposed a source energy based definition • DOE Releases (Source Energy Based) Common Definition for Zero Energy Buildings, Campuses, and Communities – September 16, 2015 10

DOE/EPA Initiatives/Programs Relating to ZEBs Building Rating Systems • EPA Portfolio Manager for Commercial Buildings(Source Energy Based) • DOE Building Energy Asset Score (Source Based) • DOE Home Energy Score (Source Energy Based) • The Home Energy Rating System (HERS) Index (Site Energy Based) Residential Programs • DOE Building America Program • DOE/EPA Home Performance with Energy Star Program • DOE Zero Energy Ready Homes (HERS Index Based) Commercial Programs • DOE Commercial Buildings Integration Program • DOE Zero Energy Buildings Program • DOE Commercial Buildings Resource Database 11

Natural Gas Industry Challenges • Reluctance/Resistance to Using Source Energy in ZEB Definition(s) • Declining Competitive Position for Natural Gas End Use Technologies • Limited R&D Funding to Advance Natural Gas Technologies Needed for ZEBs • Limited Industry Resources Committed to Natural Gas Branding and Education • Overcoming Fossil Fuel Bias/Decarbonizing the Electric Grid 12

Natural Gas Industry Opportunities • DOE is Effectively Advocating it Source Energy Based Definition for ZEBs • Key Members of the ZEB Community are Interested in Working with the Industry • Existing Case Studies of Mixed Fuel ZEBs • ZEBs with Natural Gas Can Improve Cost Effectiveness • Advancing Gas Grid Decarbonization Options 13

AGA/APGA ZEB Activities • Building Analytical/Technical Support for Natural Gas in a Low Carbon Future • ZEB Stakeholder Engagement • Communication and Education • Monitor and Assess National Policies • Advance New Energy Efficient Natural Gas Technologies
