Building Energy Optimization (BEopt™)

BEopt is a software tool that can evaluate residential building designs and identify cost-optimal efficiency packages at various levels of whole-house energy savings along the path to zero net energy. It is used to analyse both new construction and existing home retrofits, as well as single-family detached and multi-family buildings, through evaluation of single building designs, parametric sweeps, and cost-based optimizations.


To help evaluate building design and cost-optimal efficiency packages.
