EASY: Whole House Energy Audit

EASY: Whole House Energy Audit logo.

Allows auditors to visually draw plans for dwellings that are being audited. Users can place objects such as doors, windows, and other openings, and specify their attributes for calculations. EASY allows users to identify approved measures for specific objects that are included on the drawings. Once generated, the reports may be printed out or viewed on the screen. EASY has been developed to incorporate the latest in Windows technology and software design methodology in order to increase the ability for a lay person without extensive technical training to complete a complex audit with relative ease and with minimal training.

EASY accounts for the varied climates, construction styles and building materials that are found throughout a region. The audits that are completed by EASY are specific to each dwelling and take into account the heating and cooling degree days for each of the specific region.
