The specific objectives of this project are to compare the human satisfaction in green-certified and conventional buildings, and to assess and quantitatively compare indoor environmental quality (IEQ) parameters in such buildings.

Climate change accompanied with increased global urbanization have led to increased demand for built environments that operate energy-efficiently and use renewable sources of energy. In parallel, the percentage of time that people spend indoors has increased to approximately 90%, where the indoor environmental quality shapes occupants’ health, well-being and the productivity.

One of the main objectives of green and healthy building certification systems is to improve building design and operation with respect to the environmental impact and occupant satisfaction. However, few detailed studies have investigated whether such buildings lead to higher occupant satisfaction with IEQ.
