Abstract:
Indoor Environment Quality (IEQ) presents a very significant challenge in vulnerable population. In order to maintain an indoor environment that is adequate for occupants, it is necessary to comply with a set of requirements regarding concentrations of airborne pollutants and hydrothermal comfort conditions. There are factors which influence indoor environmental qualities like airborne contaminants or pollutants (construction, furnishing activities), indoor air qualities, ventilation, humidity, thermal environment, light and lighting comfort, acoustic comfort. It has vital effect on the health of human being. Indoor environment quality can be improved by various ways like by using fragrance free and volatile organic compounds cleansing products, vacuuming regularly, cleaning the equipment and maintain it. Ventilation and optimizing of light is another effective method for improving indoor air quality. The indoor environment can be influenced or altered by building services: lighting systems can increase indoor light levels; and heating, ventilation and air-conditioning (HVAC) systems are used to control temperature and humidity. With biological ageing, a number of sensory changes occur as a result of the intrinsic ageing process in sensory organs and their association with the nervous system. These changes can in turn change the way we perceive the environment around us. It is important to understand these changes when designing for older occupants, for instance, care homes, hospitals and private homes, as well as office spaces given the developments in the domain of staying active at work until older age. In this paper we will discuss about indoor environment quality, factors and aging challenges.
