Wenqi Guo, Tania Ullah

Real-time electricity monitoring in residences is a growing market, with a number of systems being commercialized that provide feedback to occupants on electrical power and energy consumption. These systems are also useful for research purposes, by better

Sustainability Performance of the NIST Net Zero Energy Residential Test Facility Relative to a Maryland Code Compliant Design

March 30, 2015

Author(s)

Joshua D. Kneifel, Eric G. O'Rear

The National Institute of Standards and Technology (NIST) received funding through the American Recovery and Reinvestment Act (ARRA) to construct a Net-Zero Energy Residential Test Facility (NZERTF). The initial goal of the NZERTF is to demonstrate that a

Design Challenges of the NIST Net Zero Energy Residential Test Facility

March 26, 2015

Author(s)

Betsy Pettit, Cathy Gates, Arthur H. Fanney, William M. Healy

Homeowners and builders have increasingly strived to build low energy use and environmentally friendly homes. As materials and equipment have improved, energy reduction as a goal has increasingly been replaced with the goal of net-zero energy use. But the
