About Home Energy Audits

The potential results of an audit are reduced energy costs through better performance, as well as improved comfort, safety, and air quality

   Nicholas Lawler of Telemark in Wainscott is one of the few on the East End qualified to perform a home energy efficiency audit that follows national standards of the Building Performance Institute. The potential results of an audit are reduced energy costs through better performance, as well as improved comfort, safety, and air quality.
    During an audit, the safety of mechanical equipment and indoor air quality are measured, while the performance and condition of insulation, sealing, and windows are evaluated for possible improvements. A blower door test, for example, forces air out of the house using diagnostic equipment to determine how much of an air exchange reduction is needed to reach acceptable levels. The data are then evaluated via a software program back in the Telemark office, leading to an analysis of how improvements will yield savings in energy costs.
    Completed forms can determine whether the New York State Energy Research and Development Authority will contribute up to $250 toward an audit. The Long Island Power Authority also offers incentives to homeowners, for central air-conditioning and split-zone systems, for instance. Once owner-approved work is completed, the house is tested to ensure improved performance.
