What is a Net Zero Energy Buidling

A Net Zero Energy Building (nZEB) creates as much energy as it uses over the course of a year. For a nZEB connected to the utility grid, a credit is built up during the summer time when the sun is good and that credit us used up during the winter when solar production is low.

It is possible to convert any building to a nZEB buy just adding renewable energy.  However, it is generally wise to take a two prong approach of  energy reduction with renewable energy.
