We performed a total of about 100 simulations, estimating energy use for the six test case residences modeled with the current windows and with each of five replacement options. Thirty McLean Gardens residents responded to our request for a waiver to access utility records, and we checked our simulation results for the existing-windows case against these bills, tweaking some of our assumptions as a result. We also did some basic sensitivity runs to evaluate the effect of orientation and shading.The results brought some surprises (see Figure 3 for typical results for one apartment type). The first is the large projected heating savings for the storms-only replacement, an option with a far lower cost than full window replacement. This results from the combined effects of reduced infiltration and the estimated reduction in U-value attributable to a tighter system.
