HVAC ASHRAE 62.1 for the Apple iPhone/iPod touch/iPad



ANSI/ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings. Standard 62.1 has served the building industry and the public as the most prominent standard on ventilation for indoor air quality.

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 upon Standard 62.1. This app is based upon the "62MZCalc.xls" Excel spreadsheet that accompanies each copy of the Standard. You can do pretty much everything in this app that you can do in the Excel spreadsheet, in addition to creating multi-system projects and emailing results so you can perform further analysis.

Other advantages over the spreadsheet include:
  1. Easily perform ventilation calcs in the field using your mobile device.
  2. By using slider-control inputs, you can Instantly see results update as input values are changed.
  3. Easily email inputs and results in an html-formatted email and also an Excel spreadsheet for further analysis back at the office.


The screenshot below describes the overall zone input and results information. You can select the space type, input the floor area, zone population, and design airflow. This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results.
