This research site monitors the electrical consumption as well as the interior space conditions of a production built, net zero energy home. Located in Newberry, Florida, it is a single story three bedroom / two bath home with 1546 sqft of living space and a HERS rating of 1. Energy consumption is offset by a 5.4 kW photovoltaic system. It has double pane, low e vinyl windows, R-15 wall insulation, R-30 ceiling, and a radiant barrier. Heating and cooling is provided by a 2 ton, SEER 16 heat pump with all ducting in conditioned space.
