Ranawaka, I and Mallawaarachchi, H (2018) A risk-responsive framework for green retrofit projects in Sri Lanka. Built Environment Project and Asset Management, 8(5), pp. 477-490. ISSN 2044-124X
Abstract
Purpose: The purpose of this paper is to evaluate the risks associated with green retrofit projects in Sri Lanka in order to develop a risk responsive framework. Design/methodology/approach: The survey method under the quantitative approach was selected as the research methodology as this research is required evaluating the risks associated with green retrofit projects. Both preliminary survey and the main questionnaire survey were conducted to collect the data. The survey data were evaluated and analysed by using mode value as a descriptive statistical analysis technique, and the risk rating matrix. Findings: The overall results of risk assessment deliberated that there are ten “critical” risk factors, such as construction cost, inflation, energy saving uncertainty, warranty risk, delay in project completion, productivity and quality risks, requirement of permits and their approval, design changes, damage to structure or property and procurement delay influencing green retrofitting. Finally, a risk responsive framework was developed by proposing suitable strategies for mitigating the risks associated with green retrofitting. Practical implications: The developed framework can be used as a basis to mitigate the risks associated with green retrofitting projects. An abundant upgrade of existing high-rise buildings into green can be reached. Originality/value: A little attention paid on green retrofitting and the absence of proper risk management strategy for green retrofit projects in current practice have made this research a paramount need and a focal point.

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
