  1. An Overview of BPA’s Ductless Heat Pump (DHP) EffortsPresented by: Kacie Bedney, BPA Energy Efficiency Mechanical Engineer

  2. How did this get started at BPA? NEEA, Mitsubishi and Grant County PUD, implemented a small, technology demonstration project of ductless heat pumps (DHPs) in the Moses Lake area. Project Purpose: Study market acceptance of the new product Determine installation costs & issues Result: Positive response from homeowners…………………

  3. How did this get started at BPA (Con't)? BPA was interested in the project results, but wanted to monitor three homes. Monitoring goals: • Get an initial look at the energy use of strip heaters and DHPs • Gain some experience with the DHP monitoring setup Results: This looks promising! Let’s implement a bigger sample!

  4. Two Concurrent Tracks Track 1: BPA Program Pilot • Based on RTF “provisionally deemed” as cost effective • Conduct research of energy savings to move from “provisionally deemed” to simply, a “deemed” measure • Learn how to best structure our program Track 2: Technology Innovation (TI) Project (Monmouth) • Detailed sub-metering • Provides insights into DHP system operating characteristics

  5. Track 1: A BPA Program Pilot BPA Planning Team, lead by Lauren Gage (BPA), Jill Steiner (Sno PUD), and Anu Teja (NEEA) • Determined the DHP program evaluation protocols for a BPA Pilot. • However, rather than running a concurrent pilot, we asked NEEA to coordinate a regional pilot that included the Investor Owned Utilities (IOUs). BPA was the major funder of the NEEA Pilot, which also received funding assistance from other NW utilities.

  6. Track 2: A TI Project (Monmouth) Lead by Adam Hadley, inherited by Kacie Bedney Project installed 14 DHPs in single family homes: Monmouth (11), Tacoma (1) and Moses Lake (2) Criteria for the TI Project: • Existing, single family home • 1-year of pre-DHP billing history • Existing home must have zonal electric, resistant heat (i.e. baseboard, ceiling or “in the wall” heater) • Billing history showed winter, electric resistance heat usage

  7. Track 2: TI Project (Monmouth) Con't Goals for DHP sub-metering: • How little do the homeowners use the electric resistance heat? • How much do they depend on the DHP? • Sub-metered data will be correlated with billing history to better understand energy saving potential & billing history analysis. • Lays the groundwork for determining cost and energy savings data to determine if DHPs provide reliable, cost-effective energy savings.

  8. TI Project (Monmouth) Results Based on the results of these 14 homes: • The saving estimates are approximately 4,442 kWh per year • DHPs provide a minimal increase of cooling energy DHPs show promise as a future savings measure for the region.

  9. TI Project (Monmouth) Results BPA’s report by Ecotope issued in June 2009, was shared with public and investor-owned utilities around the region to support their planning efforts for 2010. The results provided the support BPA needed to expand our reimbursements for additional applications and encourage installations in manufactured homes and multifamily housing. The results also provided experience that helped refine the metering plan for the NEEA Pilot.

  10. Next Steps: • NEEA DHP Pilot will confirm the energy savings for single family applications • BPA will follow up with measurement and verification on manufactured homes and multi-family housing from our current reimbursement offerings • BPA is considering other applications for DHP e.g. small commercial, forced air furnaces, etc.
