TREAT Software

TREAT is innovative software designed to provide support for energy programs, building performance contractors and energy auditors.

TREAT was developed by a team of energy efficiency professionals with extensive field experience, and takes into consideration the many facets of energy usage that occur in real buildings.

Maximum control of the building energy model is offered with a high level of input detail and a powerful SUNREL hourly simulation engine running ‘behind the scenes’. SUNREL is an upgrade to SERIRES version 1.0, a simulation engine written originally under the guidance of the Solar Energy Research Institute (SERI, now the National Renewable Energy Laboratory, NREL).

The SUNREL engine powering TREAT is an energy simulation engine intended to be used as a simulation tool for evaluating small energy efficient buildings – in particular buildings whose energy loads are dominated by the interaction of the building envelope with the environment.
