Calculate Your Whole House Fan Energy Savings
|
The engineers at AirScape are passionate about statistics to develop energy efficient products. Weather and the Whole House Fan go hand and hand, our Energy Calculator predicts the energy savings of your Whole House Fan. The database that drives this calculator is a TMY (typical meteorological year). An added benefit of this data is the ability to look at the annual temperature peaks and valleys. |

Based upon your weather and temperature input, this graph displays the product of cooling hours multiplied by temperature differential
Typical year daily temperature ranges
A typical year of daily maximum and minimum temperatures with the blue horizontal bar based on your indoor temperature information plots the days. Ideal conditions for a Whole House Fan are hot days with cold nights, if the majority of days are ABOVE and BELOW the BLUE BAR, you’re in a perfect Whole House Fan region.
Daily solar radiation
The solar load can greatly influence your cooling requirements
Notes
- The graph entitled 'Daily Ranges' is a plot of a typical year of daily maximum and minimum temperatures. A blue horizontal bar has been drawn based on the indoor temperature you input.
- For a whole house fan to be effective, we need to have days that are hot, with cold nights.
- If you have a lot of days with temperatures above the blue bar AND below, then you're in a perfect whole house fan area.
- 'Degree-Hours' graph has been computed based upon your weather and temperature inputs. This graph shows the total and in which months there is the best potential for using a whole house fan.
- The third graph 'Daily Solar Radiation' is interesting, since solar load can greatly influence your cooling requirements
