Properly Installed Insulation:
Without zero-tolerance insulation, it’s like wearing a jacket open and loose on a bitter cold winter day.
If it were below freezing outside, you wouldn’t wear your coat unzipped. The same idea applies to your home: without properly installed insulation, you’re letting the heat escape from your home much like your body heat escapes when you’re not bundled up in cold weather.
Tight Construction:
Airtight construction is like closing a hole the size of an open window in your wall.
Having a continuous air barrier in a home is critical. The small holes in the building envelope from electrical and piping penetrations throughout a home add up to a significant source of lost energy if not sealed properly.
Properly Sized Equipment:
Start-and-stop air conditioner operation hurts efficiency and lifetime just like driving a car every day in busy stop-and-go traffic.
Air conditioners need to run for longer periods of time in order to achieve maximum efficiency and to optimally cool and dehumidify the house.
Pressure Balancing:
Now you can have privacy along with proper airflow and comfort in your bedrooms.
In many homes, unbalanced pressures caused by unbalanced heating and air conditioning systems can create comfort issues because the airflow designed to reach a room can’t get there, especially when the doors are closed. With a pressure balanced system, air can flow to and from each room freely regardless of whether or not the door’s open, helping to maintain consistent temperatures.

In an effort to prevent pollution and avoid risks associated with global climate change, the Environmental Protection Agency created the Energy Star® program. Energy Star® is a voluntary partnership that includes more than 2,400 builders, developers, retailers, and product manufacturers who are working to build homes that use energy more efficiently.
