TREAT

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 HERS ratings and load sizing. Generates XML file for upload to online database tracking systems.
