Martabid, J E and Mourgues, C (2015) Criteria used for selecting envelope wall systems in Chilean residential projects. Journal of Construction Engineering and Management, 141(12): 05015011, ISSN 0733-9364
Abstract
Building envelope selection greatly influences the building's performance. Specifically, the envelope wall system (EWS) definition is a critical part of this selection, especially for residential projects. This selection is a complex decision, as it depends on multiple considerations (e.g., cost, structural behavior, energy efficiency) and involves multiple stakeholders (e.g., developers, constructors, users). Simplified approaches considering only a few criteria are often used in the decision-making process, potentially leading to suboptimal solutions. The literature points out some relevant criteria; however, there is a need to present an integrated approach to the EWS selection problem. As an initial step, this research presents a case study that identifies and formalizes the criteria for selecting EWSs in Chile, and assesses the preference of Chilean decision-makers for these criteria via interviews and surveys. Results include thermal, acoustic, and structural behaviors, cost, complexity of construction, safety and environmental impact, durability, and appearance. The most important criterion is the structural behavior, while the least important one is the complexity. This case study will expedite a better and comprehensive assessment of EWSs and will support a structured and traceable decision-making methodology.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
