From #Energy Guzzler to Near #ZeroEnergy Home: Via @HomeEnergyMag

Between 2012 and 2014, DOE sponsored the Phased Deep Retrofit (PDR) study in 60 all-electric Florida homes. The purpose of the study, which was conducted by researchers at the Florida Solar Energy Center, was to establish annual energy and peak energy reductions from two levels of retrofit—shallow and deep. As part of the study, one of the homes with very large starting energy use received extensive retrofits, enabling it to move from a large user to a near zero energy home. Results from the ten-home deep retrofit segment showed savings large enough (averaging a measured reduction of 39%) that some homeowners chose to go further by adding a solar photovoltaic (PV) generation system. This paper describes how the owners of the home referred to above moved over a period of four years from excessive electricity consumption to near zero energy in a hot-humid climate
