The purpose of this paper is to show that, while the buildability concept and habitation comfort have been studied extensively, these have so far been examined separately. In particular, the implications, which the Total Building Performance (TBP) concept may have on buildability, are as yet unknown. Arising from this lacuna, the objective of this study is to develop an understanding of the relationship between buildability and the two TBP mandates of Indoor Air Quality (IAQ) and visual performance (VP).
In studying the relationship between the IAQ and VP mandates and buildability, a base model was used to establish the baseline for comparison. This base model was adopted from the Code of Practice on Buildable Design implemented by the Building and Construction Authority in Singapore. The incorporation of IAQ and visual performance guidelines on the base model was examined to assess their influence on the buildability score.
Analysis for the IAQ component yielded a slight increase in the buildability score after the incorporation of the guidelines. However, this was not the case in the visual performance component, where there was a slight decrease in the buildability score. Nevertheless, the reduction does not affect the buildability score significantly. The minimum buildability score requirements set by the Building and Construction Authority in Singapore were still met after the incorporation of the guidelines. This seems to suggest that there is minimum effect on the buildability score arising from the implementation of both the IAQ and visual performance mandates.
The study determined that the two TBP mandates of IAQ and visual performance do not have any significantly adverse effect on buildability. Building professionals can therefore incorporate appropriate IAQ and visual performance guidelines in their architectural layout designs without compromising on buildability.
This study presents a better understanding of the relationship between buildability and the two TBP mandates of IAQ and visual performance.
