Analysis of the indoor environmental quality's impacts on human performance

Indoor Environmental Quality (IEQ) has been known for decades to has strong influence towards productivity. A poor IEQ will bring negative impact on workforce health. However, until now IEQ factors have not been taken into consideration by office management or building contractor. Especially in Indonesia, attention is only put to selling price, size, location, and facilities. Hence, this research aims to discover the effect of IEQ (thermal, lighting, and colour layout) on human performance and discover the optimal combinations of those. This research found out that those factors have significant impact on human performance and discovered that temperature of 23.5°C, lighting of 500 lux and blue colour as the layout is the optimal combination. The increase of office management and interior designers' awareness to consider IEQ factors in designing a productive workplace environment is expected in regards to this result.
