Performs hourly simulations for single family, multifamily, and mobile homes. Comprehensive analysis tool includes tools for retrofitting heating and cooling systems, building envelopes (insulation and infiltration), windows and doors, hot water, ventilation, lighting and appliances, and more. Weather normalizes utility bills for comparison to performance of model. Highly accurate calculations which consider waste heat (baseload), solar heat gain, and fully interacted energy savings calculations. Create individual energy improvements or packages of interactive improvements. Also performs load sizing. Generates XML file for upload to online database tracking systems. Complies with HERS BESTEST. Approved by the U.S. Department of Energy for use in Weatherization Assistance Programs. TREAT now supports HPXML data exports. TREAT is available in Single Family and Multifamily Versions! TREAT Multifamily is a DOE WAP tool for all MF building types.

Weatherization, Home Energy Raters, Home Performance with Energy Star Contractors, Insulation and Mechanical contractors, Mechanical or Energy Engineers performing multifamily building energy analysis.
Building components libraries are used to input building geometry and thermal characteristics, heating and cooling equipment and system characteristics, lighting, appliances, ventilation, and hot water. Imports utility bills and daily weather data.
20 user-selected, formatted reports printed directly by TREAT; generates custom program-designed reports for weatherization, home performance programs or HERS providers. Exports project data in XML format which may be uploaded to online database and tracking system.
Comprehensive and highly flexible whole building retrofit tool, easy to use graphic user interface which includes libraries of building components (walls / surfaces, windows, doors, appliances, lighting, heating and cooling, and hot water). Performs utility billing analysis including weather normalization. Calculations consider solar heat gain and waste heat generated by baseload and fully interacted savings from energy retrofit measures.
