Welcome
The Net-Zero Energy Residential Test Facility (NZERTF) is a unique laboratory at the National Institute of Standards (NIST) in Gaithersburg, Md. A net-zero energy home produces at least as much energy as it consumes over the course of a year.
Both a laboratory and a house, the two-story, four bedrooms, three-bath NZERTF would blend in nicely in a new suburban subdivision. It was designed and built to be approximately 60 percent more energy efficient than homes built to meet the requirements of the 2012 International Energy Conservation Code.
During the first year of operation (July 2013 – June 2014) the house exceeded its goal with enough surplus energy to power an electric car for about 1400 miles. Instead of paying almost $4,400 for electricity – the estimated annual bill for a comparable home in Maryland – the virtual family of four residing in the all-electric home actually exported energy to the electric grid. Additional details can be found by reading “NIST Test House Exceeds Goal; Ends Year with Energy to Spare”.
The following links describe the changes in operational strategy that were made to further improve the energy performance of the NZERTF, the enhanced measurement capabilities that were added to the facility, and a brief summary of tests that were conducted between July 1, 2014 and September 30, 2014 to measure the homes infiltration rate, to evaluate the impact of elevated indoor temperature on volatile organic (VOC) concentrations, and to quantify the performance of the three earth-coupled heat exchangers surrounding the NZERTF.

However, the number of new U.S. millionaires did fall after the market crash. At the end of 2011 there were just over 5.1 million millionaires in the United States -- 165,360 fewer than in 2007.
