If one were to try and build a better house. One must start with the building envelope for all residential housing to achieve Zero Net Energy (ZNE). It is financial risk for an architect, builder to prove the home performance prior to living in the home to the homeowner. Traditional construction has a history of failure for energy efficiency and high cost to operate house. A high performance house requires new design and construction techniques, a tighter building envelope, new types of insulations with little historical data performance history. A tighter building envelope and will result in lower cost to operate the home buyer or for a remodel of an existing home. The other added benefits are to create a more comfortable home living environment in multiple different climates zones with good indoor air quality.
The factory type of (ZNE) construction can make a real difference for proven energy efficiency houses. A factory uses a protected environment to construct its houses from inclement weather. The factory uses computer operated machines (CNC) to close the tolerances of construction connection points for the body of the building envelope on the assembly line. The factory finished units is pre-tested using test equipment prior to its delivery. The actual travel for delivery of the unit moves over highways (vibration testing) and 60 miles an hour (wind tests) to its destination job home site. In the book, “Zero Net Energy Case Study Homes – Volume 1” by Edward Dean one of Modular Lifestyles factory built houses was one of five selected to be a Case Study. Our affordable factory built house has the same equal footing in this (5) unit Case Study comparison for (ZNE) home performance to other site builder’s homes.
