Abstract

This paper presents one of the ongoing validation efforts using a low-load residential house: the Net-Zero Energy Residential Test Facility (NZERTF) located on the campus of NIST in Gaithersburg, MD, USA. Among a set of validation tests performed at NZERTF, this paper presents the preliminary results of the free-floating test during the heating season when the HVAC system stayed OFF for one week. The EnergyPlus model of the NZERTF was first created based on as-built drawings and then refined to properly reflect measured performance. Highlights of this work includes the use of advanced interzonal and infiltration airflow calculations using a CONTAM airflow program and a comparison of two ground heat transfer models to improve the EnergyPlus model.
