DC Completes Year-Long Study on Net Zero Model Home

Year Long Study of Net-Zero Energy Home Completed Successfully

It has now been a year since the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has been built and its energy harvesting capabilities began to be monitored. The home was built on the campus at the National Institute of Standards and Technology (NIST), where scientists and researchers conducted a computer simulation that replicated the energy consumption of a family of four. The results showed the home to be a success, since after a year the home generated 13,577 kWh of energy. This is about 491 kWh more than was needed.

The test home measures 2,700 square feet (252 sq m) and is a two-story home, which was built to resemble a regular home. The home is equipped with a rooftop mounted solar panel array, which was able to harvest enough energy to create the surplus despite being hindered by very bad weather during the winter. For about 38 days the 32 photovoltaic panels were covered by snow yet still managed to harvest enough energy to power the home and create the surplus.
