New ASHRAE iPhone App
September 1, 2010

Calculating ventilation rates is now a little easier with a new iPhone application designed specifically for an interactive calculation spreadsheet related to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE’s) ventilation standard.

The ASHRAE Standard 62.1 app, developed for Apple’s iPhone, iPod touch and iPad by Carmel Software Corp., allows for convenient calculations while in the field, performing the outdoor air calculations found in the Ventilation Rate Procedure and the interactive 62MZCalc spreadsheets contained in the ASHRAE User’s Manual for Standard 62.1, Ventilation for Acceptable Indoor Air Quality.

The ASHRAE 62.1 app, which applies to the calculations and spreadsheet in the 2007 standard and User’s Manual, can also be used to determine 62.1 compliance of simple ventilation systems (single zone, 100 percent outdoor-air and changeover-bypass VAV) as well as more complex ventilation systems (single-path, multiple zone recirculating) and can operate in both IP and metric units. Other benefits include the ability to store and access multiple projects within the app and also to email inputs and results for use in a spreadsheet at a later time.
