2016, Tsinghua University Press and Springer-Verlag Berlin Heidelberg. This study developed and tested a home energy audit methodology that can be operated easily and quickly by novices in the field of building physics, mechanical systems, and building energy simulations such as homeowners. The home energy audit methodology was composed of three procedures as follows: an initial simulation procedure that can run the simulation easily, a calibration procedure that calibrates the initial simulation using a year of monthly utility bills, and a procedure to determine energy and cost efficient measures. In the previous study, the procedure for calibrating a residential simulation was developed, and in another study, the procedure was applied to an existing single-family house and energy and cost efficient measures were determined. In the previous studies, the procedures were validated in one case-study, single-family house in Texas, USA. In this paper, the overall procedure for the home energy audit methodology is presented and verified by two additional single-family houses in two different locations in Texas. In a similar fashion as the application to the first house, the most suitable retrofit measures for both of the new houses were determined according to their building and systems conditions, and corresponding cost savings.
