Brunei Darussalam is one of the world's developing countries albeit being small. The country faces sustainable challenges related to energy efficiency and environmental
quality. These issues can be tackled through the implementation of bioclimatic strategies into building design and construction. Green wall and roof in buildings aimed to reduce the indoor air temperature without excessive use of mechanical cooling systems. This thesis is aimed to investigate the effectiveness of this strategy in Brunei, comparing an enclosure retrofitted with green wall and roof with the one without under the same setting.
Results revealed that both green wall and roof showed significant reduction of indoor temperature during peak daytime periods. The green wall experiment has shown 3.5°C maximum indoor temperature reduction while green roof experiment has shown 5.4°C, both during peak daytime hours, showing maximum temperature decrease of 9.1% and 13% respectively.
The same experiment was conducted using simulation by Design builder showing 98.2% and 97.8% peak maximum indoor temperature match for green wall and roof respectively. The indoor temperature reduction was proved to be inadequate to reach optimum comfort for building occupants and to eliminate the use of air conditioners. The study suggested that green infrastructure alone cannot fully mitigate the use of mechanical cooling systems but still be able to reduce their usage. This led to energy savings and improved energy efficiency in buildings. Green wall and roof have the potential to enhance thermal comfort and biophilic benefits in buildings, creating more pleasant indoor environments for occupants. In general, the findings of these experiments emphasize the possibility of green wall and roof as a versatile answer for enhancing indoor spaces, advancing sustainability, and improving the well-being in buildings.  aDissertation (Master of Science) - Universiti Teknologi Brunei   aInclude bibliographical references  4vThesisaUniversiti Teknologi Brunei  4vFinal Year Report aUniversiti Teknologi Brunei 10aBuildings xRetrofitting zBrunei Darussalam 20aArchitecture and Energy Conservation zBrunei Darussalam  4aSustainable BuildingszBrunei Darussalam 1 cDreSupervisoraMohamed Rashid Embi
