NIST Net Zero Energy Residential Test Facility

TW project increases energy savings performance! 
Tweaking ventilation and temperature control systems, along with a mild winter, helped the experimental net-zero-energy house at the National Institute of Standards and Technology (NIST) quadruple the amount of surplus energy it sent to the power grid during its second year-long demonstration

On March 3, 2016:

Thanks to all of you for making this project such a success!
 
We are currently in the process of making changes for the third year of testing. The major change will be the use of a high velocity heat pump system and associated ductwork. Operation will be alternating on a weekly basis between the conventional heat pump system and the high velocity system.
