October is Energy Awareness month and what better way to start it off than to talk about a great project underway in Virginia. CNN recently ran a story about the Net Zero house that was built by the National Institute of Standards and Technology (NIST) as a test facility to experiment with alternative energy high-efficiency systems.
The 2,700 square foot home on NIST’s property in Gaithersburg, Virginia is home to a “virtual” family – Father, Mother and two children. The house is powered by solar panels and geothermal systems while hundreds of devices that actually simulate the family’s energy use.
While the home looks like a standard middle class home that you might find in any suburban neighborhood the home cost about $2.5 million to build. That is mostly due to the elaborate systems being utilized and tested. The appliances, plumbing and heating systems are programmed to turn on and off based on the time of day. For example at 6:15 am, a computer that is housed in the garage which is ‘control central’ triggers the valves in the basement to turn on the water flow to the showers. Of course, it doesn’t take into account Johnny leaving the lights and TV on his bedroom all day.
One very cool aspect of this project is that everything in the home, except one small devise, is manufactured in the U. S. and is able to be purchased and used in a typical residence.
Other facts about the construction of the house such as geothermal loops that extract heat from earth as opposed to the air and walls constructed to reduce energy loss and keep the home at a comfortable temperature will provide great data that can be used in future construction.
There are net-zero homes that are being built in parts of the U.S. but this home will provide incredible research that can be applied to construction standards going forward. Watch the video for a full review of the project:
I think we will learn a great deal from this project and it will help us in the quest for net-zero homes but… how do you feel about using a virtual family? I think we’re going to miss out on learning about behavior and this is an area which we may understand the least.
