    2. 2. WHAT WERE WE THINKING? <ul><li>Phase 1 - not “Energy Star” , just affordable </li></ul><ul><ul><li>Weatherization training prepared us for proper sizing of HVAC and optimizing or “gaming” the software . </li></ul></ul><ul><li>Phase 2 - retrofitted to meet “Energy Star” . </li></ul><ul><ul><li>Cost upgrades split with the builder, in return for his tax credits </li></ul></ul><ul><li>Phase 3 – change insulation types, truss re-design, and upgrade bath exhaust fans. </li></ul>ST.

    3. 3. WHAT WAS OUR GOAL? <ul><li>Our first focus was low maintenance and quality construction. Low utility bills were important. </li></ul><ul><li>Our “Energy Star” education began with the energy rater who argued the importance of Cost vs. Value of Energy Star upgrades </li></ul><ul><ul><li>- What were the simplest cost effective measures? </li></ul></ul><ul><ul><ul><li>Windows, HVAC sizing, insulation </li></ul></ul></ul><ul><ul><li>- Increased marketability – low utility bills and indoor air quality- “verified” </li></ul></ul>ST.
