Sometimes new green jargon is a lot for the newly green to feel comfortable with. Net zero is a term with many definitions but all run in a similar vein. In a nutshell, net zero means no overall energy consumption or “net zero” and zero annual carbon emissions. In other words, even though some energy is used, the energy is from renewable energy sources and no energy is purchased from the grid or external energy producers because the home produces as much energy as it consumes. Hence the term “off the grid”. There is extensive information out there for the person wanting to learn more about net zero. The White House is doing research on net zero energy green building design technologies and strategies. According to the Federal paper on Net-Zero Energy, High Performance Green Buildings (October 2008), “the greenest energy is that which is not used”. Are net-zero homes affordable for the average consumer? One builder, Ideal Homes based out of Norman, Oklahoma built a zero energy home for under $200,000. Why can’t we do this other places too where lot prices are reasonable? I am always dissapointed when I attend green home events and home prices are so high the average consumer could never afford them. You Tube has many videos on Net-Zero Energy, Zero Energy homes and buildings. Wikipedia has several definitions of zero-energy building. ASHRAE or the American Society of Heating, Refrigerating, and Air-Conditioning Engineers does a lot of research and has a lot of information on Net-Zero homes and commercial buildings.
