Abstract

In 2012 the National Institute of Standards and Technology (NIST) completed the construction of a Net-Zero Energy Residential Test Facility (NZERTF) http://www.nist.gov/el/nzertf/ to demonstrate that it is possible to achieve net-zero for a house with conventional architecture, amenities, and size compared to homes in the surrounding area. The facility also serves as a test bed to evaluate residential renewable and energy efficient technologies and various approaches to improving indoor air quality. Built on NIST’s Gaithersburg, MD campus, this LEED Platinum home incorporates a vast array of renewable and energy efficient technologies. Unique features include three independent ground source heat exchangers, a radiant basement floor heating system, a solar hot water system with variable solar collector area and storage capacity, a 10.2 kW photovoltaic system, and a ducted heat recovery ventilation system. The facility also incorporates three different means of providing conditioned air throughout the house – a sealed sheet metal air distribution system; a high-velocity air distribution system; and provisions to incorporate a multi-head mini split heat pump system.
