Integrating sustainability and buildability requirements in building envelopes

Abstract

Purpose -The purpose of this study is to present the importance of integrating common features between the Green Mark Scheme (GMS) and the Buildable Design Appraisal System (BDAS) requirements in building envelopes. Design/methodology/approach -The study presents the common features that influence both the GM score of the building envelope and the buildability score of the wall system. A case study is developed to show the effects of varying the value of a representative common feature in the GM score and the buildability score. Findings -The study finds that lengths of window and wall, and wall materials are the common features that can influence the GM score of the building envelope and the buildability score of the wall system. The case study suggested that the window-to-wall ratio (WWR), which is the representative common feature, shows negative relationship with the GM score of the building envelope and positive relationship with the buildability score of the wall system.Research implications/limitations -The results show that varying the WWR influences the GM score of the building envelope more strongly than the buildability score of the wall system. This seems to imply that building professionals when determining the WWR may have to concern themselves with the GM score of the building envelope more as compared to the buildability score of the wall system. Originality/value -The study suggests that integrating the common features between GMS and BDAS requirements with other relevant factors such as cost, social and environmental impacts of design can help to save workload, time and budget, as well as facilitate the delivery of more reliable design, planning and management from a practical viewpoint.

Knowledge-based Decision Support System Quality Function Deployment (KBDSS-QFD) tool for assessment of building envelopes

“…This can be seen for example in Singapore where there are a number of regulations implemented to promote sustainability and buildability in building designs [40]. However, compliance with these regulations does not guarantee satisfactions of the stakeholders of a building project [5]. Singhaputtangkul et al [40] suggested major criteria applied by the architects and engineers in Singapore for achieving sustainability and buildability in the assessment of the building envelope materials and designs as shown in Table 1.…”

“…For instance, because of inadequate consideration of requirements, designers may not be able to develop a comprehensive design, which may lead to numerous adverse impacts during different project phases [16]. Singhaputtangkul et al [5] suggested that inadequate consideration of building envelope requirements by designers tends to lead to redesigning activities, particularly when new assessment criteria have to be additionally considered. These activities can cause progress delay, project delay, increase in expenses and increase in manpower needed of a building project [10].…”

“…Buildability BC5: Ease in construction with respect to time The material, design and construction techniques should be labor efficient while promoting high buildability. a Calculation of the GM Score can be found in Singhaputtangkul et al [5].…”

“…A thoughtful building envelope assessment can make a building work more effectively for its builders and occupants as part of stakeholders of a project and indoor environment [4]. Thus, success of the project is tied with the assessment and selection of building envelope materials and designs that can satisfy requirements of the stakeholders [5].…”

Envelope Thermal Performance Analysis Based on Building Information Model (BIM) Cloud Platform—Proposed Green Mark Collaboration Environment

“…A case study to identify the relationship between Singapore's Green Mark Scheme (GMS) and the Buildable Design and Appraisal System (BDAS)'s requirements for building envelopes was conducted by Singhaputtangkul et al [24]. Singhaputtangkul et al [24] discovered that the lengths of windows and walls and the associated materials influence the Green Mark (GM) score of the building envelope and the buildability score of the wall system. In addition, they further concluded that varying the window-to-wall (WWR) ratio has a stronger effect on the GM score, in terms of the building envelope in comparison with the buildability score of the wall system.…”
