Abstract
This research conducts a study on sustainability awareness of apartment facade design in Malaysia. The scope of this study limits to a comparative analysis between colonial and vernacular style facade design. Vernacular style is derived from the traditional architecture to the condition of the place and environment in tropical setting. The style is a logical choice in warm and wet climatic conditions, ideal for creating air movement, ventilation and escape of warm air, thus bringing in thermal comfort to the occupants. On the other hand, colonial style is an expression of classical structures and motives. The architecture does not only have dominant classical style’s expression from Europe, it also has a mixture with the local style due to adjustment of the classical style to the tropical setting, which can be seen at heritage buildings erected during colonial time in Malaysia. Two contemporary apartments built in Putrajaya are selected in these two case studies; each has a design approach with colonial and vernacular architectural style. A camera device named Fluke® Ti20 Thermal Imager was used to capture a series of thermal images on a surface of the apartment facades. This camera captured photos of the apartment facade in hourly time during the field works. The study finds that the apartment with vernacular style’s facade design has higher sustainability awareness than the apartment with colonial style’s facade design. In conclusion, by applying vernacular style in apartment design, it provides awareness to the designer and architect to come with traditional passive design elements which are embedded as part and parcel of the design in a context of tropical climate.

Abstract
The dearth of low-cost housing (LCH) provision in Nigeria calls for urgent attention and Malaysia as a fast-growing developing country mitigated a similar encumbrance, hence the need to review the LCH policies of the two countries. This will provide a better understanding of the mechanisms that were adopted by the Malaysian Government and suggest same to Nigerian Government with a view to mitigating homelessness in Nigerian cities. Drawing a systematic review of published literature, this paper reveals that Malaysian Government role in LCH provision is encouraging, although there are still some lacunas; already receiving the necessary attention by the stakeholders concerned. This paper reveals that the Malaysian LCH policies created opportunities for the poor, and therefore promote pro-poor growth to have a home while the Nigerian government policies encouraged inequality and enhance high disparities in access to financial credit for housing purpose by the low-income earners (LIEs) due to lack of framework and institutional failure. The paper conclude that LCH policies and programmes should be sustainable economically; socially acceptable, and technically feasible. In addition, the policies and programmes should enhance cooperation; consultation, sharing knowledge within the stakeholders and ensure that the LIEs can gain access to homes.

Abstract
The role of a house is more than a shelter, but a place for us to grow and affect us physically and psychologically. In today’s world, housing prices are rising faster than wages in many parts of the world. In Malaysia, house prices particularly in urban areas such as Penang and Kuala Lumpur had risen rapidly over the past few years. This situation has caused many people especially the medium and low-income groups unable to afford a house of their own. Through the Malaysia Five-Year Plan, various programs are created and have been undertaken by both government bodies and private agencies in order to help to increase home ownership amongst its citizens. So far, the government of Malaysia has done a job well done in combining the effort of the public and private sectors to build affordability houses for its citizens. In order to enhance the current available housing policies, the government of Malaysia should turn towards other developing countries and learn from their housing program. One particular method that has been explored and adopted by many countries and has been proven to be quite successful is the sharing home ownership. In 2014, Penang became the first state in Malaysia to introduce such scheme. This paper therefore discusses the possibility of implementing sharing home ownership schemes in a higher level throughout Malaysia.

Abstract
The quality of indoor environment is crucial in office buildings. In a direct way, it affects the occupants’ health and performance. A large amount of energy is usually required to provide and maintain acceptable indoor thermal and lighting conditions. It is found that working spaces are mainly illuminated by artificial lighting systems, which are responsible for a major part of the total energy consumption. The lighting conditions of the interior space can be enhanced by the efficient utilization of natural lighting and the reduction of the amount of energy used. The window to wall ratio (WWR) and the type of glazing play a significant role in controlling the transmitted daylight into space, as well as the heat exchange between the interior space and the outside environment. This paper aims to investigate the impact of the WWR and the glazing type on the total energy consumption. The potential energy savings are also investigated. A parametric analysis was conducted to achieve the research objective using modeling and simulation methods. The main findings of this study showed that the large reduction in the energy consumption can be achieved when a certain glazing type with a high value of visible transmittance is used at small WWR. The type of glazing with a better thermal performance, on the other hand, provides the highest energy savings with larger WWR. The most suitable window area varies according to the zone orientation.
