Energy Star
Program
Guaranteed Watt Saver, located in Oklahoma City, provides this verification service for Paul Methvin Homes, Inc. Prior to constructing a house, GWS analyzes the houseplan, planning the heat and air layout and unit size, and rating the energy efficiency of the house. During construction, GWS inspects the house at the wall insulation stage to verify correct insulation installation prior to installing sheetrock. When construction is complete, GWS performs a blower door test to determine the home's airtightness.
Homes that earn the Energy Star designation must be at least 30% more energy efficient than homes built to the 1993 Model Energy Code or 15% more energy efficient than state energy code, whichever is more rigorous. These savings are based on heating, cooling, and hot water energy use and are typically achieved through a combination of:
Building envelope upgrades (better sealing of exterior walls)
High performance windows
Controlled air infiltration
Upgraded heating and air conditioning systems
Tight duct systems
Upgraded water heating equipment
These features contribute to lower energy usage, lower utility bills, increase friendliness to the environment, and provide greater home comfort.
When you buy a home, look for the Energy Star label on the electrical circuit box. If the home doesn't have the label, don't buy it!
