IEQ Calculator(Office) app for iPhone and iPad

IEQ calculator (Office) provides you an easier alternative to estimate the indoor environmental quality (IEQ) in office environment. You can examine the IEQ performance of an office by simply inputting several preset indoor environment parameters. The environmental performance of the office is expressed via a 5-star benchmarking scale (i.e. 5-stars BEST office, 1-star WORST office). This application is particularly useful for building management officers.
