Kajian Persepsi Arkitek terhadap Pelaksanaan Bumbung Hijau di Malaysia: Faedah, Halangan dan Cadangan

Abstract

The implementation of a green roof as a sustainable method to reduce the urban heat island effect is still new in Malaysia. Although it has not been tested on a city scale, many studies have found that green roofs can balance the impact of urbanization by improving environmental quality. Its low usage in Malaysia is due to various factors, such as cost and the lack of awareness among the construction industry players. This study aims to identify the perceptions of local architects towards the implementation of green roof and its benefits, obstacles and recommendations to overcome the challenges in implementation. Questionnaire survey were used to determine the views of local architects, on ten benefits, nine obstacles of green roof implementation and eight recommendations to overcome the green roofs obstacles. The results indicated that the most important green roof benefit was minimizing the urban heat island effect (N = 8.14). Meanwhile, the weakest green roof benefit was increasing the roofing thermal insulation (N = 3.73). The most significant obstacle of green roof application was the constraint of implementation by the client (N = 4.22), with the weakest obstacle was inadequacy in the confidence of the architect towards the benefits of the green roof (N = 2.62). In addition, the most significant recommendation to overcome its implementation obstacles was enhancing the incentive to green roof operators (N = 4.37), while the weakest recommendation is by bringing in foreign expertise and technology transfer (N = 3.65). The findings of the study will facilitate in promoting the implementation of green roofs in Malaysia and enhancing the contribution of the green roof to the interior and exterior environment of buildings.
