what is a net-zero home?
Basically a net-zero home produces as much energy as it consumes. These homes minimize energy use through efficiency and renewable energy systems to successfully reach a Home Energy Rating System (HERS) rating of zero, which is the industry standard for measuring a home’s energy efficiency. A typical resale home has a HERS rating of 130 and a standard new home has a rating of 100. Reaching a 0 rating means the home is completely self-sustaining.
There are a number of ways a home can reach the HERS rating of 0. Innovations that increase efficiency include sophisticated insulation, advanced framing techniques, and pre-cut floor joists and pre-built trusses. These homes often rely on renewable power sources like solar and conserve energy with home automation equipment lighting and small appliance controls, programmable thermostat, and real-time energy analytics that show consumers how they’re using energy so they can make their habits more environmentally friendly.
