So what features make an Energy Star Certified home different than typical Knoxville homes for sale, and what value do those features bring?  The features according to the Energy Star website are:
Optimal Value Framing and insulated headers: This is good for energy efficiency and good for the environment.
Closed/Conditioned Crawlspace. These perform better than a vented crawlspace in terms of safety, health, comfort, durability, and energy consumption.
Energy Star windows. These help reduce energy bills and reduce condensation. The benefit is a cooler home in the summer and warmer home in the winter.
Air Sealing. This is basically sealing every hole where wires penetrate through a wall (both interior and exterior). For those searching Knoxville real estate for some peace and quiet, Air Sealing reduces outside noise leading to a quieter home. It allows for less pollen, dust, pollution, and insects to enter the home. It lowers the moist air flow through a home ultimately improving the durability of the structure. It also lowers energy use, leading to lower utility bills.
Improvements to ductwork and overall HVAC improvements. The sealing of ductwork prevents leakage of conditioned air and can improve a system’s efficiency as much as 20%. Ductwork is wrapped in insulation and oftentimes an additional layer of insulation is blown over the ductwork in the attic. 15 Seer seer, high efficiency gas HVAC units can be located in the conditioned crawl space.
Energy Star fixtures. Energy Star rated lighting uses 1/4 the energy of traditional lighting and are constructed to last longer.
Energy Star Appliances. These appliances incorporating advanced technologies can 10%-50% less energy and water than standard models.
Thermal Air Barrier Alignment. This ensures that there are no gaps, voids, or compression in the insulation materials. An effective air barrier leads to a tight house and minimal lost energy.
Tankless Hot Water Heaters. These provide hot water only when needed. Traditional storage water heaters produce standby energy losses that cost the homeowner money. When looking at Knoxville homes for sale, keep an eye out for this upgraded feature.
Radiant Barrier Roof Deck. This stops radiant heat through your roof, reducing temperatures in the attic by up to 30 degrees!
Stavros concluded, “As you can see there is a big difference in what goes into an Energy Star Certified home. The biggest difference though, is what you will be paying the utility companies every month.”
