Stop 4: Earl Williams of Earl Williams & Associates gave us a passionate presentation and his team provided plenty of specific details as we walked through his remodeling project. Faced with an extremely tight budget and timeline, Williams focused on the most practical energy upgrades and attainable water conservation measures. They overhauled the existing HVAC duct system and zoned the rooms, resulting in a downsizing of the new 16-SEER unit, installed tankless water heaters, replaced existing toilets with new dual-flush and HET products, and installed new low-flow faucets and showerheads. Recycled materials, including DuPont Zodiaq countertops, add to the green features. Energy Star appliances and lighting fixtures were used throughout.
