Abstract
Purpose: The excellence in design and greater efficiencies (EDGE) certification system has seen a gradual adoption worldwide, with Ghana having six out of its eight certified green buildings bearing an EDGE certification. However, little is known about occupants' satisfaction with the indoor environmental quality (IEQ) of EDGE-certified buildings. Therefore, the purpose of this study is to examine the satisfaction of occupants with the IEQ of an EDGE-certified building in Ghana by identifying their perceived performance of the indoor environment relative to their perceived importance. Design/methodology/approach: A survey was conducted to evaluate the performance of 12 IEQ parameters with the occupants of an EDGE-certified office building. The survey results were evaluated using a gap analysis and both traditional and alternative Importance-Performance Analysis (IPA) matrices. Findings: The findings revealed that noise level, temperature, cleanliness, sound privacy, air quality and humidity were IEQs that required the highest priority for improvement. Daylight and artificial lighting showed no appreciable performance gap. Space layout was adequately satisfied, whereas space size was overly satisfied. Visual privacy and outdoor view were found to require low priority of improvement. Originality/value: This study contributes to the state-of-the-art of the IEQ of green buildings. It pioneers the research that seeks to examine the IEQ of EDGE-certified buildings. The gap analysis and the IPA were effective in prioritizing the IEQs for improvement action and provided a practical research framework that helped researchers examine the performance of green buildings, thereby giving valuable feedback to policymakers and building owners.

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
