## What is IEQ Calculator (Resident)?

IEQ calculator (Apartment) provides you an easier alternative to estimate the indoor environmental quality (IEQ) in residential environment. You can examine the IEQ performance of an apartment by simply inputting several preset indoor environment parameters. The environmental performance of the apartment is expressed via a 5-star benchmarking scale (i.e. 5-stars BEST apartment, 1-star WORST apartment). This application is particularly useful for tenants to evaluate the IEQ in their own livings.
