ACKNOWLEDGEMENTS AND CERTIFICATION
research described herein has been performed with major funding provided by the
Office of Energy Security, Minnesota Department of Commerce and matching funding
provided by the Energy Systems Design Program. Additional in-kind support has
been provided by the Rochester Public Utilities. The Codes and Standards
Division of the Minnesota Department of Labor and Industry provided valuable
review and feedback during the development of the MQT.
While this financial and in-kind support is gratefully acknowledged, the Principal Investigator assumes complete responsibility for the contents herein.

The Minnesota Residential Energy Quantification Tool (MQT) has been developed to assist Minnesota Energy Utilities in rapidly and accurately assessing the impacts Building Energy Code changes and energy conservation measures on the utility bills of their residential customers in both single- and multi-family buildings.
The MQT is designed to be calibrated against Utility meter readings allowing the effects of conservation measures to be quantified in terms of historical energy consumption data. As such, the MQT is not a building energy simulation program that claims absolute accuracy.
The MQT employs a state-space analysis approach to solving the energy balances of zones within the building as well as the energy balances of all the building envelope components, including the below-grade components. A novel approach for including earth contact heat transfer has been developed and included in the MQT. This approach enables a rapid calculation of a building’s 8760 hour annual transient energy performance and yields detailed heat transfer results for the building envelope components.
The MQT is
embodied in a computer program with a very simple, self-guiding user interface.
The program will be made freely available for download from the Energy Systems
Design Program web site
