For this project, net zero energy is defined as a building using as much energy as it generates on an annual basis.
THE BIG DISCLAIMER: Energy models are just that: models. They are not guarantee of actual performance. Moreover, energy use is very user dependent. Some people use a lot, some use a little...because of this neither True Turtle nor CAT Consulting will not provide any guarantees that net zero energy is possible. However, given the energy model, it appears achievable. In fact, neither True Turtle nor CAT Consulting guarantees any specific energy performance of this building in any way, shape or form. We realize this will be disappointing for some, however, given we cannot predict who, or even how many people will reside in this home there is no way for us to guarantee how much energy will be used.
