• Technology Oriented • Business Driven • Sustainable Development • Environmental Friendly Result – Explanation • High relative humidity (RH) leads to condensation, causing air to become damp/stuffy. This stuffiness makes it difficult for chemicals to be removed from the indoor environment • Formaldehyde emissions and levels increase with the increase of relative humidity • RH in hotels ≈75% possibly due to water vapour (from outside/making coffee inside hotel room/ vapour from the hot water bath). If it increases by another 25%, it becomes saturated and condensates, forming water. Thus making it difficult for chemicals to be exhausted. • Poor MVAC maintenance and fresh air supply leads to neurological problems caused by chronic exposure How bad is this issue? Samples Number Office Home Public Mall Hotel Total TOTAL 546 303 102 154 38 1163 • High RH also related to the growth of microbial biohazard agents • Some microbes will produce allergic VOCs called Microbial Volatile Organic Compounds (MVOCs) which will affect your throat and upper respiratory tract even in acute exposure • MVOCs will cause allergic rhino sinusitis and chronic skin rashes • Most Hotels investigated were “4-6 Star” hotels
