Business Review


The Building Control (Environmental Sustainability) Regulations, introduced in 2008, require buildings to attain minimum scores under the Green Mark Scheme (GMS) in Singapore. The Building Control (Buildable Design) Regulations, introduced in 2001, require buildings to attain minimum buildability scores under the Buildable Design Appraisal System (BDAS) in Singapore. It appears that both the GMS and BDAS can influence building designs and must therefore be considered concurrently to yield the optimal results. Consideration of both sets of requirements is illustrated using a case study of one 18-storey residential building. Through interviews, the study also explores the issues relating to integration management for green business, i.e. if architects consider BDAS and GMS requirements at the design conceptualization stage. The case study suggests a slight decrease in the buildability score when modifications were made to lower the residential envelope transmittance value (RETV) to obtain a higher Green Mark score. The interviews seem to suggest that architects do not consider BDAS and GMS requirements concurrently. Instead, they seem to think that considerations for BDAS and GMS do not have significant effect on each other and that on the contrary these might even complement each other.
