1 California Advanced Homes Program Master Builder Overview Advanced Home Design and Building Practices 2016 Code Readiness Program

2 CAHP Master Builder Incentives and Offerings Financial incentives $30,000 - Option A: Both high performance attics and high performance walls $20,000 - Option B: High performance attics only $10,000 Option C: High performance walls only $15,000 Multifamily: High performance walls, continued use of ducts in conditioned space or energy-use equivalent 25% of incentives are paid at start of the 1 st lot and 75% are paid upon verified installation of all 25 Increases CAHP incentives (estimated from ~$1,000 to ~$3,000 per house) Consulting services Facilitated design charrette/workshops with design team, consultants, and contractor present Facilitated value engineering meeting with design team, consultants, and construction team present 250 hours of dedicated design and construction assistance from subject matter experts (SMEs) throughout the project

3 CAHP Master Builder Incentives and Offerings Technical training and resources Individual, one-on-one technical assistance and support Regular meetings, phone calls, and communication with program team On-site training for the design team, energy consultants, and subcontractors Installation guides and guidance from product manufacturers Limited availability Three builders in San Diego Gas and Electric service area Single family and multifamily eligible Municipal service, propane, or all-electric developments are ineligible.

4 CAHP Master Builder Eligibility A participating CAHP Master Builder s responsibilities: Select participation option (limited availability first come, first served) and implement one of the following Both measures: high performance attics and high performance walls High performance attics only Complete a minimum of 10 lots by June 30, 2017, permitted under 2013 Code requirements Agree to post occupancy monitoring for temperature, moisture and energy use in two houses per development Agree to feature project in a case study Agree to be recognized and promoted at industry events and in publications

5 High Performance Attics Recommendations to meet 2016 Title 24 standard 1. Strategies to reduce duct loss 2. High performance attics (HPA) and ducts in conditioned space (DCS) Applicable in Climate Zones 10, 14, 15

6 1. Cool attic or High Performance Attic (HPA) No change to thermal envelope Vented attic Addition of insulation at roof deck Above: HPA A Below: HPA B 2. Sealed attic or Unvented Attic or (UVA) Move thermal envelope Four Ways to Reduce Duct Loss 3. In the house or Ducts in Conditioned Space (DCS) Relocate ducts and air handling unit inside the home or 4. Go ductless!

7 High R Value Walls Recommendations to meet 2016 Title 24 standard 1. Traditional wall assemblies 2. Alternative wall systems Applicable in Climate Zones 10, 14, 15

8 2013 Code versus 2016 Code Standards 2013 Code: Residential Package A Prescriptive Standard Assembly U Factor of in all climate zones Typical assemblies R , 16oc or R , 16oc 2016 Code: Residential Prescriptive Standard Assembly U Factor of Variety of assemblies possible: R , 24oc R , 16oc R , 2 x 16oc These are prescriptive assemblies: Performance tradeoffs are possible.

11 Sample High Performance Wall Design Assembly U Factor should equal approximately R 25 to accommodate for potential loss through thermal bridging

12 Alternative Wall Systems Structurally Insulated Panels (SIPs) Insulated Concrete Forms (ICFs) Benefits: Minimal thermal bridging Factory fabricated Lower labor costs Seismic durability Delivery costs can be significant

13 Program Value Leadership Set the example for the industry Prepare for the Future Educate full team of designers and workforce for the next code cycle Experience Learn from product manufacturers and subject matter experts Financial Support Minimize initial education and experience costs
