1. NORTHWEST ENERGY EFFICIENCY ALLIANCE RBSA Metering Study May 4, 2011

2. Context/History for RBSA Metering Study ‎One of several RBSA “Optional Studies”  Basic framework for sub-metering included in original RFP ‎Several formal & informal discussions  July 2010: RBSA Core Group meeting update  September 2010: meeting at Council  Dec 2010: post Efficiency Connections NW update  Feb 2011: Northwest Research Group update ‎For expediency, project evolved from main RBSA project flow, but coordination remains 2

3. 3 Metering Study Goals  Support 7 th PP development  Updated characterization of home energy by end-use  Updated end-use load shapes  Foundation for further field testing (“Regional Testbed”)

4. Overall Study Architecture RBSA Sample (~1400) Heat Loss Assessment (~500) Fully Metered (~105) 4 Possibility to grow metered sample to full 1400 with non- intrusive load monitoring (NILMs) devices

5. Study Components 5 RBSA/Blower Door Physical characteristics + blower door sample Triple Metering Whole house, heating/cooling, hot water, (gas) Plug Loads TVs, home entertainment, home office Major Appliances Refrigerators, dishwashers, clothes washers/dryers, etc. Lighting Overall home energy use from lighting

6. Sample Design 6

7. 7 Regional Testbed ‎Testbed to serve as proving grounds for new EE products, services, and practices.  RBSA Metering Study is the foundation for the Regional Testbed  PNNL/DOE providing over $380k in 2011 for Metering Study  Nearly $600k for Testbed startup  First testing project: NILMs

8. Non-intrusive Load Monitoring (NILMs) ‎Advanced, non-intrusive metering technology which disaggregates signal to identify individual loads  Several devices at or near release  Do they work?  Can possibly use to expand size of metered test bed very cost effectively 8 Intel prototype
