This is a powerful computer program with a comprehensive weather database of 211 U.S. cities that shows just how much you can save by installing a programmable thermostat (or adjusting your regular thermostat) ~ try it for your home or office. The program takes minutes to learn – and saves energy for years. It does industry-standard engineering calculations behind the user-friendly interface.
This program does calculations based on the annual weather data for each location. Heating and cooling are basically heat transfer, which is directly proportional to the temperature difference between the inside and outside.
How To Use This Program
The values you get depend only on the (inside – outside) temperature difference times the efficiency of the system times the cost to run the system. It’s a very straightforward calculation that you can have confidence in.
Granted, there are many variables unaccounted for, like insulation. However, this analysis gives the RELATIVE DIFFERENCE in how you set the thermostat.
