Active Design for Better Indoor Air Quality
In comparison to a conventional HVAC system, carbon dioxide (CO2) sensors at the SCTC ensure that the optimal amount of fresh air is supplied to indoor areas and treated to improve indoor air quality and energy e ciency. We also used environmentally friendly low Volatile Organic Compounds (VOC) products for all building interior nishes to minimise risk of irritation to occupants.
Conservation Measures for E cient Water Use
To be more e cient with the use of resources, rainwater is collected from the 3,000 m2 catchment area and stored in a 31,000 litre High Density Polyethylene (HDPE) tank underground and a 10,000 litre HDPE tank in the basement. This water is then used for irrigation purposes.
Water e cient ttings have also been installed throughout our building and save more than 40% potable water compared to the LEED baseline standard.
