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