Slide 1 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N BPA Commercial Showerhead Research Plan RTF April 6 th, 2010 Danielle Gidding

Slide 2 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N February 2010 RTF  Commercial showerhead measures presented to RTF for direct install: –Hospitality (hotel/motel) –Hospitals –Small commercial employee showers  RTF approved commercial deemed savings as provisional for 18 months – with BPA presentation to RTF of research/evaluation plan.

Slide 3 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Commercial Analysis – February  Used residential analysis assumptions for flow rates, temperature, cost.  Adjusted showerhead utilization (minutes/year) by business type

Slide 4 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Research required for full deeming in commercial applications 1.Baseline flow rate in specific commercial applications  Collect pre and post flow rate upon installation for every installation 2.Usage information to determine annual utilization (minutes/year) of showerhead  occupancy rates  # of occupants per showerhead  showers/person/day  shower duration Data will be collected through PTR and evaluation

Slide 5 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N PTR Data Collection  Data collected through PTR for every installation (through Direct Install) –Utility information –Building information –Building type –Equipment information  Flow rate of replaced showerhead  Per unit equipment cost  Per unit installation/labor cost –Survey of building owners/managers  Estimate of showers/showerhead/day  For Hospitals/hospitality –Occupancy rates –Number of occupants/day

Slide 6 B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Data True-up  Secondary research for best information on –Estimate of showers/showerhead/day –For Hospitals/hospitality –Occupancy rates –Number of occupants/day –Minutes/shower Combine with PTR data to re-analyze savings, incremental costs, and cost effectiveness.
