Modeling Microturbines in EnergyPro

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5931 thumbs up February 21, 2019- 5:17 pm Software specific questions are usually best asked of the vendor's customer service or through one of the forums at onebuilding.org Microturbines would not be at all like solar panels since they consume gas and produce electricity. Both would need to be accounted for in the modeling results. The free heat would assume that there is waste heat recovery associated with the microturbine system. If the software cannot model this system for LEED then you need to provide a work...

The F-factor accounts for the edge treatment since this is where most of the heat loss occurs. Think of it like a whole assembly U-value of sorts. Some...
