DETERMINING BARRIERS IN SUSTAINABLE REFURBISHMENT PROJECTS: COMMERCIAL BUILDING OWNER PERSPECTIVES

Existing commercial buildings in Malaysia account for one third of the total electricity consumption. They present a great opportunity for refurbishment to reduce carbon dioxide. However, sustainably refurbished commercial buildings that is Green Building Index (GBI) certified is still low. This study aims to investigate barriers that impede commercial building owners to implement sustainable refurbishment and explore ways to increase numbers of sustainable refurbishment implementation. Qualitative data were collected through semistructured interviews. The respondents were commercial building owners’ representative, who were mainly building managers. The findings indicated that higher cost of sustainable refurbishment than conventional method and lacking of sustainability awareness among Malaysian were the main barriers of sustainable refurbishment. This study will be useful in helping building owners and developers to enhance economic, social and environmental benefits of sustainable refurbishment.

Thermal Performance of Precast Concrete Sandwich Panel (PCSP) Design for Sustainable Built Environment

Malaysias awareness of performance criteria in construction industry towards a sustainable built environment with the use of precast concrete sandwich panel (PCSP) system is applied in the buildings wall to study the structural behaviour. However, very limited studies are conducted on the thermal insulation of exterior and interior panels in PCSP design. In hot countries such as Malaysia, proper designs of panel are important to obtain better thermal insulation for building. This study is based on thermal performance of precast concrete sandwich panel design for sustainable built environment in Malaysia. In this research, three full specimens, which are control specimen (C), foamed concrete (FC) panels and concrete panels with added palm oil fuel ash (FC+ POFA), where FC and FC+POFA sandwiched with gypsum board (G) were produced to investigate their thermal performance. Temperature difference of exterior and interior surface of specimen was used as indicators of thermal-insulating performance of PCSP design. Heat transfer test by halogen lamp was carried out on three specimens where the exterior surface of specimens was exposed to the halogen lamp. The temperature reading of exterior and interior surface for three specimens were recorded with the help of thermocouple. Other factors also studied the workability, compressive strength and axial compressive strength of the specimens. This study has shown that FC + POFA specimen has the strength nearer to normal specimen (C + FC specimen). Meanwhile, the heat transfer results show that the FC+POFA has better thermal insulation performance compared to C and FC specimens with the highest temperature difference, 3.4°C compared to other specimens. The results from this research are useful to be implemented in construction due to its benefits such as reduction of energy consumption in air-conditioning, reduction of construction periods and eco-friendly materials.

Strategies in Dealing with Cost Overrun Issues: Perspective of Construction Stakeholders

Construction industry in Malaysia is one of the main contributors to economic growth, yet there are still issues related to construction cost overrun. Many factors have triggered the cost overrun issues that might have high possibility to ruin the overall performance of a construction project. To cope with these issues, determination of strategies is essential to ensure effective cost management in construction projects. This study attempts to identify strategies for current construction industry in dealing with cost overrun issues. Literature review and quantitative approach were employed to achieve objectives of the study. Questionnaires were distributed to three key construction stakeholders that are client, contractor and consultant in Penang state, Malaysia. The data obtained from the respondents were analyzed by using Relative Importance Index (RII) method. The findings indicate that the current industry stakeholders have different point of view and opinion in dealing with cost overrun issues. In conclusion, the result of this study serves as a guideline in dealing with the issue of cost overrun.

The Management Of Sustainable Development at Malaysian Local Government: Stakeholders' Perception

Sustainable development has become an important aspect of the construction industries. There are many ways sustainability elements can be incorporated in the design, construction, operation and deconstruction of a building. Importantly sustainability represents the link between society and built environment professionals. In relation to that, this study involves a look at the stakeholders outlook and interaction with sustainability. In this study, the focus will be aimed on the role of the Local Governments and how the perception of the stakeholders. Therefore, this study intend to look into the sustainable development and better understanding the strength and weaknesses and other relevant factors that promote or hinder the Sustainable Development. This study is to contribute to the enrichment of knowledge on the role of Local Governments in Sustainable Development. Therefore, this research seeks to find out whether sustainable development is being practiced and seeks to find out what is happening with respect to issues of what, how and why things are being done with the development of Sustainable Development globally and in Malaysia in general.
