Least-Cost Pathway to Net Zero Energy Homes

Net zero energy (NZE) homes require additional investments in improving energy efficiency and adding rooftop PV.  It can be challenging to determine the most cost effective way to reach NZE because it depends on climate, energy costs and relative costs of energy efficiency and PV technology options. BEopt software can be used to evaluate residential building designs, identifying cost-optimal performance packages at various levels of whole-house energy savings. This presentation will provide a brief overview of BEopt capabilities along with several case studies of NZE homes designed and built using information from BEopt.
