For all you energy modeling fans — in case you haven’t already heard — the National Renewable Energy Laboratory’s BEopt software is now available for use by the general public. Chris Calwell of Ecova attended a recent training, held at the annual Passive House Conference in Denver, and reports that the documentation is good enough that, “you don’t need too much training to fiddle with it.”
NREL’s website tells us:
“The BEopt™ (Building Energy Optimization) software provides capabilities to 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.
“BEopt can be used to analyze both new construction and existing home retrofits, through evaluation of single building designs, parametric sweeps, and cost-based optimizations.”
The NREL includes a series of free training videos.
