Criterion for BCA Green Mark (Part 2)

So continuing on from the post about the criteria of the Green Mark, today I shall discuss the remaining 3 criterion and their importance to achieving building sustainability.

 

The next criterion is environmental protection. This explores the following aspects of the building: sustainable construction, sustainable products, greenery provision, environmental management practices, green transport, refrigerants and storm-water management practices. 1This encourages building developers to install miscellaneous products that are environmentally friendly and contribute to the other categories. An example of this is storm-water management practices, where the developers are encouraged to install systems and technology to the building so as to storm water runoff before discharging it into the public drainage system. An example of a building, which scored well in this category example, would be Parkway Parade Shopping Mall. This shopping mall uses green transport technology in order to reduce emissions from transport. This includes parking lots reserved for hybrid cars; a carpark guidance system to guide users to the nearest parking lots; providing a shuttle bus so that its patrons will not travel in personal vehicles as well as providing a charging port for electric motorbikes in its basement carpark. 2 Below is the reserved “Green Lot”.

Next, we have the criterion of indoor environment quality. This criterion is important as air quality makes a big difference to the quality of the experience within the building. Indoor air quality can also be controlled to a large extent whereas outdoor air quality cannot. The scoring system incorporates the aspects of thermal comfort, noise level, indoor air pollutants, indoor air quality management and high frequency ballasts.1 An example of a building that scored well in this criterion would be Khoo Teck Puat Hospital in Yishun. For its naturally ventilated wards, wing walls were introduced in order to enhance air flow into the wards. This green environment also helps to reduce ambient heat and improve thermal insulation, hence resulting in a cooler micro-climate. This wing wall is pictured below. 4

The last criterion is for other green features that do not quite fit into any of the other categories. Examples of these include pneumatic waste collection system, carbon footprint of the development, conservation of existing building structure and a double chute system. 1 These systems all help to contribute to building sustainability in their own small but significant ways. For example, the dual chute system refers to having separate rubbish chutes for recyclables and non-recyclables. This reduces costs in the future from sorting the trash produced by these tenants. An example of a building with the dual chute system is Bottania Condominium in West Coast Road. 6
