Discovering how many of the 10 basic energy measures the contractor can provide 

So, let’s say you have a couple of contractors that make it through Level 1 questioning; this step will help you rank their whole-systems expertise levels. As a general rule, the more energy measures that a contractor can provide from in-house staff or from with-in their circle of certified subs, the more they know about how to maximize the effectiveness of each system in relationship to all the others. Here, we simply repeat the list of measures from above so you can simply ask the contractor which of these measures they can provide either with “in-house” employees or with their existing circle of certified subs.

1. Comprehensive energy assessment of all existing systems (lighting, appliances and phantom loads are a subset of the assessment) and Carbon Monoxide safety testing and corrections according to BPI* standards

2. Air sealing (including crawl-spaces) to reduce building air leakage according to BPI standards

3. Fresh air ventilation systems according to BPI standards

4. Attic prep and Insulation installation according to BPI

5. Wall Insulation installation according to BPI

6. Duct design and installation according to California best practices guide.

7. HVAC: Heating – Heat Pumps, Gas Furnaces and Hydronic heating systems. Air Conditioning – high-efficiency AC systems according to California Best Practices guide for “right-sizing” and design specifications.

8. Window replacement

9. Solar PV – design and installation in concert with whole-house energy-efficiency optimization

10.  Energy Efficiency or Green Rating of home – HERSII or Build it Green - Green Point Ratings help  to validate the increase in value of your home.
