SUMMARY

 

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 www.buildingphysics.umn.edu.
