As ASHRAE seeks to expand its mission around the globe, on-the-go access becomes increasingly important. ASHRAE is pleased to offer the following mobile apps and eBooks:


ASHRAE apps deliver the latest building technology information to the palm of your hand.

Available now from ASHRAE:

  • ASHRAE App—ASHRAE has launched a free conference-focused smartphone app for use by ASHRAE members and those interested in the Society. The app provides members with essential, real-time information on events, meetings and conferences, as well as access to top Society resources. The app is available on both iOS® and Android® platforms.
  • Psychrometric Chart App—The ASHRAE Psychrometric Chart app is the first truly interactive graphical psychrometric chart for iOS devices, and it includes both I-P and SI units. Easily plot HVAC and other psychrometric processes while out in the field, save the graphs, and then email the graph and results to yourself or clients.
  • Standard 62.1—Now in the App Store®, the ASHRAE 62.1 iPhone®, iPod Touch®, and iPad application allows you to perform comprehensive minimum ventilation calculations for a wide variety of commercial buildings based on Standard 62.1, using either I-P or SI units. This app is based on the 62MZCalc.xls Excel® spreadsheet that accompanies each copy of the 62.1 User's Manual.
  • Duct-Fitting Database—This app, available via iTunes®, allows you to perform pressure loss calculations for all 200+ ASHRAE duct fittings in both I-P and SI units. Use this mobile app in the field for quick duct pressure loss calculations. The inputs can be adjusted by touch, and installation is automatic.
  • 90.1 ECB App—A free web application from ASHRAE automates the calculations needed to show a building project’s compliance with ASHRAE/IES Standard 90.1-2010 using the Energy Cost Budget (ECB) Method described in the standard. The calculations are based on the ECB Method Compliance Forms found in the 90.1-2010 User's Manual. Input your project parameters and then calculate your proposed design’s projected performance and compliance—no need to build your own spreadsheet. Output your results in Microsoft® Excel® for your clients and project records. The app is accessible from your desktop, tablet, or other device anywhere. Set up an account and store your project information in one place for easy reference and comparison.
  • SuperheatCalc—SuperheatCalc, a free app in the Apple App Store and Google Play, enables HVAC service technicians to calculate target superheat for systems using fixed-orifice expansion devices, superheat and subcooling for 26 refrigerants, and airflow and psychrometric calculations to aid with field service of HVAC&R equipment. The app was a winner of ASHRAE’s 2016 Apps Contest.
  • HVAC PT Chart App — For Apple iPhone or iPad (Android version coming this fall), this comprehensive PT chart app allows HVAC technicians and contractors to quickly look up the temperature and corresponding pressure in I-P or SI units for 100+ common HVAC refrigerants including both bubble and dew versions of azeotropic (mixture) refrigerants. Input the temperature to get the corresponding pressure, and vice versa. Includes a database of 1000+ cities worldwide, including high elevations, to derive atmospheric pressure. Display common properties for the selected refrigerant (oil type, GWP, composition, critical temp, boiling temp, and more). This is the only PT Chart app that allows you to email complete PT chart lists, refrigerant properties, and your input values/results. Adjusts display to your device’s screen size.
  • HVAC Duct Sizer App — For Apple iPhone or iPad (Android version coming this fall), this app allows you to quickly size one HVAC duct run or a range of duct sizes using the constant friction method. Size ducts in I-P or SI units by airflow or dimensions, specifying the aspect ratio and either air velocity or friction loss. Results include both the exact and rounded height and width (or diameter) dimensions and the calculated velocity and friction loss. You can specify duct shape (rectangular, round, or oval) and air temperature and pressure. Finally, you can email HTML and .csv output of inputs and results to perform further analysis using your desktop computer. Adjusts display to your device's screen size.
