Lassandro, P and Cosola, T (2018) Climate change mitigation: Resilience indicators for roof solutions. International Journal of Disaster Resilience in the Built Environment, 9(1), pp. 4-17. ISSN 1759-5916
Abstract
Purpose: This paper aims to increase the resilience of building systems, especially roofs, in relation to climate changes. The focus is on Mediterranean cities, where, often, there is no regulation about these issues. Therefore, it is necessary to define resilience indicators through comparative studies of adaptive roof solutions to mitigate overheating in summer. Design/methodology/approach: Through software simulations and data comparison, a specific methodological approach is used to analyze the resilience levels of different roof solutions (phase change materials, aerogel, green and cool roof), starting from energy efficiency as a prerequisite of resilience. Moreover, a case study of a historic existing building in a southern Italian town is examined. Findings: The findings show the best strategies for building systems, especially for roofs, to decrease urban heat island effects according to the defined resilience indicators against overheating mitigation. Research limitations/implications: Other building systems, such as facades, also have to be investigated in relation to climate change mitigation. Practical implications: The implementation of resilient solutions that can also affect neighborhood for urban heat island mitigation. Social implications: Because of resilience indicators definition, it is easier to introduce economic incentives according to reference thresholds and to increase community involvement. Originality/value: The paper provides a new approach for the evaluation of technological solutions for a building from a resilience point of view, which has energy efficiency as pre-condition.

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
