TREAT (Targeted Residential Energy Analysis Tools) 2.5, is a software tool designed to model building energy consumption and direct clients to cost-effective efficiency upgrades in single-family and multifamily buildings. TREAT models building energy consumption using hourly weather data and the SUNREL calculation engine. The model incorporates building insulation, window, and air leakage properties; mechanical system efficiencies; and gains from solar radiation, lights, people, and appliances in its calculations. TREAT models can include multiple heating and cooling zones, as well as unheated areas. It allows users to project savings from single upgrades and packages of upgrades, taking into account interactions between measures. The software provides screens for recording and reporting health and safety data, such as carbon monoxide and flue draft measurements.
