We can't even begin to make decisions about energy and housing until consumers have access to the necessary information.
Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget.
This disparity in useful energy data is just one of several information gaps that must be bridged as the United States transitions towards residences that generate as much energy as they use over the course of a year -- so-called net-zero houses.
One such strategy, proffered by experts who attended the workshop, is to require that energy costs be listed in all real-estate transactions.
"This means incorporating energy in the appraisal process, and the valuation of principal, interest, taxes, and insurance (PITI), so that it incorporates energy cost considerations to become the valuation of principal, interest, taxes, insurance, and energy cost considerations (PITIE)," the report says.
The report breaks out three categories of challenges: design, technology and equipment, and the needs and behaviors of homeowners and the building industry.
With regard to design, one workshop recommendation is to establish a scoring system for new and used homes so that prospective buyers can "compare energy, durability, indoor air quality, accessibility, and other factors relative to their needs."
One clear need, the report says, is to help designers, builders and occupants understand how best to collect and analyze home energy data.
"Consumers require information that is useful, timely and understandable to be able to make the energy purchase and consumption decisions necessary to achieve net-zero energy for new and existing homes," the report says. [emphasis mine]
The Net-Zero Energy Residential Test Facility sits on the campus of the National Institute of Standards and Technology in Gaithersburg, Md. The facility allows researchers to test various high-efficiency and alternative energy systems, materials, and designs.
