Prescriptive Duct Sealing MH Spec Please note: These specifications are intended as the minimum requirements to achieve, on average, the RTF's UES estimates. Programs should consider adding requirements to reduce negative impacts on health and safety, to reduce costs, to increase the measure life, and to increase energy savings. 1.Ducts must not have been previously sealed with mastic. 2.Appropriate materials and duct sealing methods shall be used. A.UL-181 listed mastic is an appropriate material to seal non-flexible duct connections. Cloth-backed duct tape shall not be used to seal, secure, or fasten ducts. Loose tape shall be removed prior to sealing. Secured tape that remains must be completely covered with mastic. Where there are large gaps in sheet metal or duct connections, repairs shall be made using sheet metal, sheet metal screws, and/or mastic with mesh-reinforcing tape (for holes or gaps less than 1 inch). B.For flexible crossover ducts, both the inner and outer lining shall be tightly fastened using a compression strap tightened with a tool designed for that purpose. 3. End caps shall be made of either sheet metal or a UL-181 approved rigid product, and sealed. 4. Ducts shall be sealed from the interior at every supply register (boot-to-duct connections, floor-to-boot gaps, and any other duct connections within an arms reach). 5. Plenum connections shall be sealed (plenum-to-furnace connection and plenum-to-trunk duct connection). 6. Crossover duct connections shall be sealed (crossover duct takeoff-to-trunk and crossover duct-to-collar connections). 7. Inferior sections of crossover duct, such as rusted, crushed, disconnected, torn, or sections otherwise ineffective, shall be repaired or replaced. New crossover ducts shall be insulated to a minimum of R8. 8. Crossover duct shall be mechanically fastened and supported to avoid disconnection and airflow restrictions.

New Measure Proposal: LED Fixtures Measure Name: LED Fixtures Likely Measure Type:UES Likely Measure Category:Proven Measure Sector:Residential End-Use:Lighting Proposing Party:BPA [ currently BPA Qualified] Interested Party: BPA Regional Potential:150 to 200 aMW [overlaps with Screw-in Lamp potential] 5 – New Measure Proposal

Measure Details Measure Identifiers Fixture Type – Ceiling and Wall Flush Mount – Track Light – Exterior Security – Exterior Porch – Linear Shop Light – Linear Flush Mount – Downlight Retrofit Kit hide Delivery Mechanism – Retail – Direct Install – Give Away – Mail by Request 6 – New Measure Proposal Specification Fixture with integrated LED or Fixture with separate LED lamp provided in package

Regional Potential ~150 to 200 aMW over the next 20 years Overlaps with savings potential from CFL and LED lamps 131 million fixtures in RBSA. Assume 50% of this is installed (new, replace) over 20 years. 7 – New Measure Proposal

Data Sources Online shelf survey of regional home improvement stores – Current practice mix of technologies (LED, not-LED) – Incremental cost (analysis of lowest cost units, ideally matched-pair) – [Bonneville will provide] BPA/NEEA Lamp Shelf/Sales Analysis – Current practice for pin-based lamps (for Track Light) – Current practice for T8 lamps (for Linear Shop and Linear Flush Mount) – [Bonneville will provide if available] RTF Residential Screw-in Lamps Analysis – Current practice for screw-base fixtures (what lamps we assume socket-based fixtures get filled with) RBSA – Hours of Use by fixture type – % Conditioned Space by fixture type 8 – New Measure Proposal

New Measure Proposal DHP for New Construction 9 – New Measure Proposal Measure Name: DHP for New SF Measure Category: Planning Measure Sector: Residential End-Use: New SF Proposing Party: BPA Regional Potential: Medium

Challenges to Work Through Study Design: Data from the WSU study, but may not be able to use results directly – Design of study does not necessarily encourage the same behavior that we might expect (on the meter) Baseline: What is the baseline heating system type? – Zonal electric resistance: good savings (assumed in WSU study) – Zonal/DHP hybrid: zero savings – Electric forced air furnace: very good savings – Central heat pump: savings close to zero – Gas forced air furnace: negative electric savings – Likely a mix of above (could exclude gas where unavailable) 10

Proposed Timeline Ideally, BPA would like to see these measures addressed by November/December – LED Fixtures: Seems realistic – DHP for New construction: May take time to work through baseline question 11

Proposed Decision “I _____ move that the RTF allocate staff resources towards developing (choose) a Residential LED Fixture UES Measure a Residential DHP for New Construction UES Measure.” 12 – New Measure Proposal

Upcoming Meeting Topics Anticipated in October Prescriptive Duct Sealing SF (Planning) – Revisit savings and costs – Develop Research Strategy Performance Based Duct Sealing SF (Planning, Under Review) – Need a Research Strategy to be active Manufactured Homes Heat Pump Related Measures Research Strategy – Need to incorporate New Construction piece Residential Behavior Standard Protocol – Discuss path forward for RTF work on residential behavior Residential DHW – Showerhead – Align parameters in this measure with the Thermostatic Shower Restriction Valve New Construction – ENERGY STAR (Idaho/Montana) – Update the measures as needed for new codes and/or specifications Proposed Cost Effectiveness Methodology for Seventh Plan 13 – Upcoming Meeting Topics

Upcoming Meeting Topics Anticipated in November/December Residential Heat Pump Upgrades (New Construction) Non-Residential Lighting Standard Protocols – Revisiting Retrofits protocol with any available data – Scoping out New Construction/Code Compliant protocol Scientific Irrigation Scheduling – Sunset date extension and research update Delivery Verification Batch 3 Residential Appliances – Dishwashers Multifamily Calibration, Weatherization, and New Construction Guidelines Updates 14 – Upcoming Meeting Topics
