Simulated versus Measured Energy Performance of the NIST Net Zero Energy Residential Test Facility Design

March 30, 2015

Author(s)

Joshua D. Kneifel, William V. Payne, Tania Ullah, Lisa C. Ng

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

The Effect of Piping Heat Losses on the Efficiency of Solar Thermal Water Heating in a Net-Zero Energy Home

January 28, 2015

Author(s)

Tania Ullah, William M. Healy

This study evaluates the thermal performance of an dual-tank domestic hot water (DHW) system designed for a net-zero home at the National Institute of Standards and Technology, Gaithersburg Maryland campus. Hot water demand for a virtual family of four in

Monitoring Techniques for the Net-Zero Energy Residential Test Facility

December 31, 2014

Author(s)

Mark W. Davis, William M. Healy, Matthew Boyd, Lisa Ng, William V. Payne, Harrison Skye, Tania Ullah

NIST has constructed a Net-Zero Energy Residential Test Facility that will be used as a testbed for investigating the measurement science related to systems, components, and operations that will lead to homes that generate as much energy over a course of a

Evaluating Feedback Systems for Residential Building Energy Monitoring

August 10, 2013

Author(s)

Wenqi Guo, Tania Ullah, MengChu Zhou

Rising global energy demand, increasing electricity prices, and the limitation of natural resources have led to increased interest in energy monitoring of residential buildings. Much research has been done to examine the effect of energy use feedback to

Input-Output Approach to Predicting the Energy Efficiency of Residential Water Heaters  Testing of Gas Tankless and Electric Storage Water Heaters

November 1, 2011

Author(s)

William M. Healy, Tania Ullah, John F. Roller

A study was conducted to evaluate the potential for using a linear relationship between the power input to a residential water heater and the output of thermal energy in hot water for rating the units energy efficiency. This approach has the potential for
