Abstract

How can occupant feedback methods inform the management and design of low-carbon and whole-house refurbishment of dwellings? This is particularly relevant for large-scale, whole-house refurbishment programmes tasked with achieving deep cuts in carbon dioxide (CO2) emissions. Evidence from pre-refurbishment occupancy can influence which interventions are chosen and increase their efficacy. A critical review is undertaken of a portfolio of short- and long-term occupant feedback techniques for evaluating occupants' perception of comfort, satisfaction, behaviour, and expectations. A number of these occupant feedback techniques are then tested empirically at the pre-refurbishment stage for two discrete case-study house types as part of ongoing research. The evidence reveals wide gaps between modelled and actual energy consumption; poor indoor CO2 and daylight levels, low operating internal temperatures, as well as problematic noise transmission. Such findings influence the selection of suitable user-centred low-carbon refurbishment interventions and ensure that there is a robust learning process for building owners, occupants, designers, and building managers. To optimize time, cost, and occupant involvement, it is important that feedback from occupants on building performance focuses on 'need-to-know' rather than 'nice-to-have' factors.

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
