Purpose -The purpose of this study is to focus on identifying building elements with design defects and established the relationship between design defects and difficulties in carrying out maintenance works. Design/methodology/approach -A total of four cases have been selected covering primary-and secondary-level for both National and National-type schools (commonly known as vernacular schools). Interviews with school management were carried out throughout the study to assess the common design defects in the buildings. Findings -A list of the design defects that have caused high maintenance cost was tabulated. It could be concluded that the most common design defects are building fac¸ade and missing slot underneath the floor slab which led to more defects. Research limitations/implications -Only four schools in Penang, Malaysia were involved in this study. Data were gathered from the school management and maintenance personnel. No data have been obtained from the designers because difficulties in tracing the designers record since the school age are more than 20 years. Practical implications -The study recommended that expert maintenance personnel shall be employed in the design stage to minimize design defects in school projects which in turn minimize the cost of building maintenance. Social Implications -Safety and health of the students could be affected if there is no accurate measures being adopted to overcome the issue. Originality/value -A very limited study has been carried out with regards to design maintenance for school buildings in Malaysia.

Abstract. This is a research in progress where authors seek to investigate the factors of residential fires. As part of the research, this paper aims to analyse the fire problems faced by the community of Malaysia. Data regarding residential fires between 2012 and 2014 was collected from fire investigation reports prepared by the Selangor Fire and Rescue Department. Descriptive analysis is conducted to summarize the data collected and describe the common phenomenon of residential fires. The distributions of the fire characteristics suggested that residential fires are commonly occurred during daytime, confined within the room of fire origin, caused by electrical failure and cooking negligence, started from kitchen, and occurred in multi-units housing. Further analysis will be conducted in order to investigate the relationships between the characteristics and residential fires.

Medical waste management (MWM) in developing countries such as Nigeria continue to lag in the development and implementation of successful MWM programs. The concentration of research on management practices, waste generation and characterization, disposal practices implies very little attention has been given to understanding the factors that are critical to implementing successful MWM programs. The aim of this study is therefore to identify critical factors of MWM success in developing countries, and assess the recognition and implementation of these factors toward achieving MWM goals in healthcare facilities (HCFs) in Benue State, Nigeria. This study adopted a case study approach. Factors critical to MWM success were identified from literature and validated through key informant interviews conducted across four (4) case study HCFs. The study found that, training, sensitization and awareness was considered the most critical factor, followed by environmental legislation in compliance with international environmental rules/regulations; and specific and elaborate regulations with regard to medical waste. The third most critical factors were financing and investment; infrastructure; and adequate and efficient workforce. It was found that implementation of the critical factors at the HCFs was poor. Issues contributing to poor implementation include lack of awareness on existing medical waste management guidelines; lack of enforceable national policy or regulation on medical waste management; inadequate finance among others. This stresses the need for increased participation at both internal (HCF), and external (ministry) levels in creating awareness on the risk potential of medical wastes and existing guidelines to encourage acceptable practices, and enactment of specific legislation dealing with MWM.

Abstract. The environmental quality (IEQ) in a building is an important element to perceive the good health and comfort level for the building occupants. However, each building contributes different environmental quality results towards the indoor spaces and the occupants. Learning environment is one of the spaces that need attention as it is related to student's well being as well as their learning performance. Existing knowledge on IEQ is still limited concerning the desirable levels of air quality, maintenance, and other factors affecting IEQ in Malaysian educational establishment. Therefore, the study of indoor environment quality in buildings has been carried out in educational building as it acts as important place in learning process. The methodologies used to conduct this research are divided into two methods, which are classroom measurement normal condition and classroom intervention setting. This is done in order to compare and monitor the improvement of environment in the classroom. This research focuses on the comparison of IEQ in different classroom environment setting and the student satisfaction level in their normal classroom environment. Measurement of temperature (°C), relative humidity, carbon dioxide (CO2), Volatile Organic Compound (VOC), dust particles (PM10), lighting (lux), and noise (decibel) in the classroom were collected and questionnaires were distributed among the students. This research found that most of the elements in the classroom was incompliance with the standard threshold limit value. The level of VOC in the classroom was noted to be significantly high (11.7ppm) compared to the standard threshold limit. An intervention on the normal condition classroom was set up with selected plant placed in the classroom. Results show a tremendous reduction in the percentage of relative humidity, level of TVOC, as well as CO2.

Evacuation model is an important tool in formulating performance-based building design. It is a tool aims at helping designers assess the robustness of their design against factors such as human behaviour in fire. Currently, performance-based code for fire safety design has been the hot trend all over the world. Nevertheless, even though Malaysia is applying prescriptive-based code, performance-based approach for special buildings and mega projects are allowed. This shows that it is just a matter of time before performance-based code be fully adopted in place of prescriptive-based code in Malaysia. This paper aims to highlight how evacuation modelling may help designers assess the performance of their design. In this paper, an example of evacuation scenario was modelled and simulated using an agent-based fire evacuation model -FDS+Evac. The output of the simulation provide graphical representation such as the fire curve, the evacuation time, and the time to untenable condition that can be used to analyse the life safety objective based on concepts of ASET and RSET. The FED values of all occupants throughout the evacuation process are less than tenability criteria (0.3 FED). Therefore, it is concluded that all occupants have evacuated safely in the event of fire.
