This Walk-in Stability Chamber (WiSC) was completely design on December 2006. A preliminary study was conducted to determine its characteristic and baseline data as it was a new and custom-made design. The manufacturing cost of the WiSC was RM300,000. The objective on commercialization of WiSC is to povide a facility and services in conducting and experiment related to temperature and humidity simulations. This WiSC consists of three rooms which are chamber room, control and a changing room. The chamber room equip with a cooling unit and heating unit which is the main system to create the desire climate and indoor enviroment. It is also include with a ducting system and a safety system. The main purpose of this chamber is to conduct and experiments and studies on Indoor Enviroment Quality (IEQ) including Indoor Air Quality (IAQ), human productivity and HVAC performance. Nevertheless, it also can be utilize to conduct studies in other field such as biologist experiment, media and ink testing, physical respond test to army and athelete, agriculture testing, test the quality of product and other that related to simulation of temperature and humidity. This WiSC was also participated in International Exposion of Research and Inventions of Institution of Higher Learning 2007 (PECIPTA 2007) and winning a Gold Award in Research and Inovation Fest 2007 at UTHM.
