Basic familiarity with house construction, heating and cooling equipment, home energy auditing, and building science. Medium level of computer expertise required.
State Weatherization Assistance Programs and their local subgrantees. Utility companies. Residential energy professionals and auditors. Energy consultants and analysts.
House specific information related to the basic construction and energy features of the envelope, installed equipment, etc. is entered for each audited house by an auditor using graphical user interface data input screens. During initial program setup, local retrofit measure costs, utility costs, and other parameters are entered by the user.
A list of recommended retrofit measures ranked by SIR is provided, along with associated energy savings, cost savings, and installed cost for each recommended measure. A cumulative savings and SIR (i.e., a total savings and SIR for the recommended package of measures) is also provided, as well as a listing of major materials required to install the recommended measures. Pre- and post-retrofit heating and cooling energy consumption estimates and equipment loads are identified, and individual component contributions and total peak load estimates are available for equipment sizing. If requested, a comparison of program predictions against actual billing data is available, with the option to adjust measure predictions to reflect the billing data. Other reports include a listing of all data inputs for a requested house, a detailed work order for a home (if the work order option is implemented), and summaries of completed jobs.
The Weatherization Assistant (NEAT and MHEA) is specifically designed to be a home energy auditing tool. With minimal inputs, it is designed to be an easy to use and quick method to produce a list of recommended energy efficiency improvements specific to each home audited. Both input and output data are stored in a Microsoft Access database format that can be retrieved and processed using other software if desired.
