ENERGY STAR® qualified homes are independently verified to be at least 30% more energy efficient than homes built to the 1993 National Model Energy Code or 15% more efficient than state energy code, whichever is more rigorous. According to the EPA, these savings are based on heating, cooling, and hot water energy use and are typically achieved through a combination of:

As shown in the above diagram, heat and cooling loss occurs throughout most homes. Karsten homes are thermally insulated to keep in heat during the winter and cool air during the summer. The solid, tightly sealed construction of a Karsten ENERGY STAR® home ensures maximized savings over a lifetime.
Tighter home construction will improve the energy efficiency, air quality, and comfort of your home by eliminating unwanted drafts. Using sealant and vapor barriers create a comfort zone in your home.

UL listed tapes and duct mastic are used to seal all joints and seams in the ductwork. All Karsten Homes are built using premium mastic sealer.

Increased insulation keeps out excessive heat and cold while maintaining even temperatures inside the home. A programmable thermostat ensures even heating and cooling.

Double-glazed low "e" windows carry the ENERGY STAR® label and save up to 30% in heating and cooling loss.
These features are STANDARD in every Karsten Energy Star® home.The ENERGY STAR Advantage is available at participating locations and is subject to product availability and climate region.
