How Does the New Energy Code Affect You?

The International Energy Conservation Code (IECC) dictates code requirements for new construction and remodeling. Individual states and local municipalities can add to these standards but cannot diminish them. The goal of these mandates is to conserve more energy but the net result is to have a safer and more comfortable home. For residential applications, the following items are the most applicable:

  • Blower Door Test – This is  test that checks the air-tightness of a building. With proper insulation, windows, etc., the infiltration factor is reduced which results in a more energy efficient home.
  • Duct Blaster – This test is required only if the furnace or ductwork are located in an unconditioned space, like an attic. The ductwork has to meet code guidelines before being approved. A house must pass these two tests prior to getting an occupancy permit.

There are many other code upgrades that new homes must adhere to but these two tests are specific to the HVAC industry.

Obviously, many of the code changes are not practical or cost effective for existing homes. But two things that most homes can benefit from are proper attic sealing and insulating along with sealing your ductwork. We use a patent designed product that seals ducts from the inside. Our average duct sealing is 95% effective, which can save up to 30% of heating and cooling costs and improve airflow.
