Free Building Science Calculation Tools for Energy Professionals

What's New with RED

Custom Web Application for AirCycler

We are happy to announce the launch of the AirCycler
Annual Ventilation Cost Calculator! This innovative app, designed by AirCycler and RED and build by RED, allows the user to determine the annual cost of operating an ASHRAE 62.2-compliant ventilation system with four different AirCycler controls. The Cost Calculator is for homeowners, but also serves contractors by allowing for detailed inputs. Features include:
  • AirCycler controls are selected from a drop-down menu of four choices.
  • Weather data and fuel prices are keyed to the entered zip code, however, custom fuel prices may be used. State fuel prices are updated monthly.
  • Only three other values are required; living space area, number of bedrooms, and number of stories.
  • An annual cost range is calculated, with older, leakier homes at the low end of the range, and newer, tighter homes at the high end of the cost range.
  • Contractors or homeowners can customize the cost range for a particular home by selecting the detailed inputs and entering the required values.
