Abstract

The main objective of this study is to look into the Usage of Passive Solar Design to Reduce Thermal Heat Gains of Buildings. Today's civilization depends to some extent on the energy economy, and it is impossible to even imagine a life without energy for a moment. Therefore, all countries are seeking sustained energy and maintain stability in all possible way. Even though majority of the people in Malaysia know about passive solar design, but there are not much of them has using the passive solar design in their buildings. Many of the people may not concern about the environmental issue so they might not know what damage they will cause to the earth if they continuously using the mechanical equipment such as air- conditioning. This leads to the research objectives to develop in this study, in which the design principles, advantages, problems and ways to solve the issues regarding the passive solar design are to be examined in this study. This study has adopted quantitative research method, which is survey questionnaire to target the group of people who may involve in the construction industries such as architects, clients, contractors. In addition, non-probability sampling technique, such as convenient sampling method was used to collect the data required from the respondents. Eventually, the researcher has successfully collected a total of 55 respondents as the final sample size to analyse using SPSS. The results have shown that most of the respondents perceived that passive solar design can lead to advantages such as cost-saving, reduce emission, low maintenance and good for health. However, the respondents also think that the problems exist related to the passive solar design, such as lack of public interest and awareness due to dearth of exposure, Roofing Materials and Design that are not in confluence with Solar Systems as well as Thermal insulation, thermal mass, and Shading. Thus, various suggestions were given in relation to each problem stated in the study.
