Purpose
Greening existing buildings (GEB) considerably improves energy efficiency of old buildings, along with other benefits, but it is not widely practiced. As a part of a wider study, this paper aims to evaluate the perception of building dwellers/owners on the challenges and motivators to GEB in Brunei Darussalam.
Design/methodology/approach
A structured questionnaire survey collected 109 responses from building owners/dwellers. Cronbach’s alpha tested the reliability of the data collected. One-sample t-test examined if sample means are consistent with population means. ANOVA examined if different respondent groups significantly agreed on the importance levels of individual factors. Moreover, factor analysis narrowed down the long list of factors in to a smaller number of components.
Findings
A set of 30 challenges and 19 motivators of GEB was identified. “Lack of a GEB infrastructure” was identified as the collective key challenge, leading dwellers to recognize lack of support and knowledge and develop wrong perception on GEB. However, “framework of supports,” as a summative motivator, improves knowledge and awareness on GEB, which allows recognizing other benefits and developing a momentum of practicing GEB. Factor analysis suggested a consolidated approach for challenges through six interrelated components, but for motivators to focus on somewhat four independent areas. Originality/value House/building dweller/owners’ decision is the key to undertake GEB. This study, apparently for the first time, contributes to identifying the challenges and motivators that influence their decision-making.
