* Estimates of outdoor air volumes by building area are generated from the Pacific Northwest National Laboratory publication, "Achieving The 30% Goal: Energy and Cost Savings Analysis of ASHRAE Standard 90.1-2010" (Table 4.14) or default values from ASHRAE Standard 62.1-2010. These are estimates only. For actual airflows, consult with your engineer.
This program is designed to generate a financial analysis for HVAC systems that utilize Airxchange energy recovery wheels. The program uses ASHRAE weather data and ASHRAE 97.5% design days for the cities listed.
Utility rates and installed costs vary depending on location and equipment selection. Default values are provided in order to demonstrate estimator results. For actual rates and installed costs, consult your local utility and HVAC contractor.
For engineering analysis of specific applications, please use Airxchange's performance and selection software.
