    What exactly is HERs

    The Home Energy Rating System (HERS) is one of many national standard for measuring the energy efficiency of a home. Typically the older the home, the higher the rating (consuming more energy and costing more dollars to maintain). Even most new homes, while somewhat improved over an older home, is typically in the mid-range and will still cost the homeowner (vary based on usage like mpg in a car) a greater monthly expense in utility bills. It may sound good, but it has not achieved a healthy and lower utility cost.

    To achieve a low monthly energy expense, the home needs to be free of drafts and leakages in the building shell envelope, allowing for a mold and mildew ‘sandwich’. Building leakages not only deteriorates the home’s ability to attain a low energy usage, but in a short time, deteriorates the indoor air quality contributing to illness of the occupants.

    An Insulsteel Free Energy Living (Net Zero Energy) Home is so airtight, it attains one of the lowest HERS scores and surpasses that criteria to achieve LEED Platinum Certification.
