IAQ Specifications for a Netzero Energy Research Home
Andrew K. Persily, Lisa C. Ng
The National Institute of Standards and Technology (NIST) recently constructed the Net Zero Energy Research Test Facility (NZERTF) to demonstrate a range of technologies in support of achieving netzero or near zero residential buildings (1). The energy goals of the NZERTF are addressed by a combination of a well-insulated and airtight building envelope, efficient heating and cooling equipment, and solar thermal and PV systems. In addition, ventilation and IAQ issues were addressed in the design of the building through a balanced mechanical ventilation system with heat recovery and detailed specifications for low-emitting building materials. A measurement program has been implemented to verify that the IAQ and ventilation goals are being achieved. These measurements include envelope airtightness, ventilation system airflow rates, thermal comfort, and the concentrations of volatile organic compounds including aldehydes. This article describes the design of the building, with a focus on the ventilation and IAQ requirements, and discusses the measurements to verify that the ventilation and IAQ goals are being achieved
