Gultekin-Bicer, P; Anumba, C J and Leicht, R M (2018) Advanced energy retrofit projects: Cross-case analysis of integrated system design. International Journal of Construction Management, 18(6), pp. 453-466. ISSN 1562-3599

Abstract

Built environment researchers and practitioners are addressing the current sustainability and energy challenges facing the industry. The shift in building energy and sustainability expectations has led project teams to develop new practices and processes. Owners, project managers, designers and contractors now actively seek opportunities to improve the energy performance of existing buildings through retrofitting. Given that integrated system upgrades result in more significant energy reduction rates than traditional approaches, this study adopted a case-study approach to understand the integrated system design process and its effects on energy-efficiency performance measures in retrofit projects compared to traditional retrofit processes. Within this scope, three retrofit projects with different processes and rate of energy consumption reduction were purposefully selected to meet certain project delivery and system design characteristics. This paper focuses on effects of these characteristics on the collaborative decision-making process and integrated system design. Its main contribution lies in the analysis of critical decisions related to process and performance modelling practices in the delivery of retrofit projects. As a consequence, it was found that while collaborative energy benchmarking and performance goal setting provided a transparent decision-making environment, the review of existing conditions prior to design and the use of historical operational performance data made the iterative energy modelling of an integrated building system design realistic.

Descriptive scope: 4 PCTE

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
