Urbanisation inevitably shows a positive sign in increasing the economic reputation of a country. Nevertheless, it has led to several problems including the deficit in green spaces and destruction of the natural environment, therefore green building is introduced as an alternative to overcome crucial environmental issues. Numerous approaches were also adopted to reduce other environmental issues such as urban heat island, air pollution and lack of green spaces. One of the sustainable approaches that help to minimise the environmental problems is by using the means of vegetation or plant material on rooftops or also known as the green roof. The implementation of the green roof on top of buildings is becoming a trend in the urban cities as it provides numerous benefits to the green development. The green roof is also part of criteria in green building and among the benefits, implementing green roofs will reduce heat flux, optimise energy efficiency and improve stormwater management. However, despite the benefits, enhancement on the green roof installation and maintenance consideration are two factors which are still largely unexplored as the main significant factor in the viability of the green roof installation. Hence, this paper is aimed to determine the vital criteria of maintenance and its ranking towards the establishment of best practice maintenance for the green roof, by focusing on high-rise residential. Questionnaires were distributed by email and through an online survey to 30 maintenance managers of green roof of high-rise residential in Kuala Lumpur and the samples are drawn by using purposive sampling technique. The results showed that the most significant maintenance criteria of the green roof are drainage, followed by waterproofing, irrigation, water retention, and roof slab. The outcome of this study has provided a significant contribution to the current maintenance practice of green roof by prioritising the criteria of maintenance and key address of green roof, where it may help to standardise the maintenance practice of the green roof in the tropical climate of Malaysia.
Most universities and college campuses across Malaysia are engaged in developing policies, programmes, and systems to reduce fire risks, and maintain fire safety. Although the awareness of fire disasters has increased among some parts of the society, the concept of fire disaster preparedness and response in universities has not been sufficiently explored. Therefore, this paper aims to establish a conceptual framework fire safety management plan in Malaysian Higher Educational Institution. The method used by this paper is synthesizing previous articles from selected journals and conference proceedings, reports, standards on disaster risk management, higher institution contingency and fire safety plans, and existing guidelines from authorities. The key elements of fire safety variables from the previous literatures assist this study in developing a conceptual framework related to fire safety management plan. The findings of this paper include the elements of fire safety management like organizational responsibilities (mitigation/prevention), emergency preparedness including emergency facilities, emergency contact details, information, and communication training, and testing and reviewing (response & recovery). The establishment of this conceptual framework of fire safety management can guide the management teams at higher educational institutions in delivering information to Emergency Response Team (ERT) to ensure its effectiveness. Moreover, this framework will help the management team to adopt, validate, and evaluate, which enhances the ability to detect crisis signal that will minimize losses.
Numerous problems arise due to the development growth of a country such as the destruction of natural environments and the deficit in green spaces. Thus, in order to overcome these issues, an alternative by implementing green building has been introduced. One of the sustainable approaches in a green building that can be implemented is the green roof. The utilization of a green rooftop over structures has gradually turned into a pattern in urban communities as it gives various advantages to the nation. The objective of the study is to analyse the criteria of maintenance and the rank of each criterion in approaching towards the establishment of best practice of the maintenance for the green roof, by concentrating on high-rise buildings for residential. The data were collected from respondents using the distributed questionnaires through email and via online survey. A total of 30 maintenance managers were drawn as the sample for the study by using purposive sampling technique, where 20 were returned and valid for analysis. Descriptive statistic of mean ranks and standard deviations was adopted for analysis. The most significant criteria in green roof maintenance are drainage, followed by waterproofing, irrigation, water retention and roof slab, based on the result obtained. The result of the study provides a significant improvement to the existing practice in the maintenance practice of the green roof by highlighting its maintenance criteria and key address, as it may assist to standardize the maintenance practice of green roofs in the Malaysian tropical climate.
The implementation of green roof on top of buildings is becoming a trend in the urban cities and provides numerous benefits to the green development growth. Despite the benefit and enhancement on green roof installation, maintenance consideration is still largely unexplored as the main significant factor in the viability of green roof installation. This paper is aimed to identify the significant criteria of green roof maintenance practice in Malaysia. The literature findings revealed that there are generally twenty (20) criteria pointed as maintenance criteria. Out of 20, six maintenance criteria were identified as the most significant factors towards the best practice of green roof maintenance.
The construction industry is developing rapidly and become one of the backbones of the country. At the same time, building and sustainability are often highlighted important and connected to one another. Even the country has come out with a momentous milestone of the Twelfth Malaysia Plan (2021-2025) with 14 game-changers, where one of them is focusing on advancing green growth for sustainability and resilience. Hence, Green Building Index (GBI) is introduced in Malaysia as a rating system that aims to promote the use of energy efficient. Sustainable construction in building development have been shown to have a clear positive impact on the environment, it has been highlighted as the current trend in environmental protection. However, different advantages and disadvantages are enticing and discouraging the contractors from implementing sustainable construction in their projects. Therefore, this study is conducted to determine the barriers in implementing sustainable construction among contractors in Malaysia. In attaining the objectives of this study, quantitative approach is adopted, where quantitative data is utilised in the methodology phase via questionnaire survey. The data collected were analysed using SPSS Software and presented in the form of descriptive analysis of mean, standard deviation and ranks. The findings of the study found that the main critical barrier faced among contractors in the application of sustainable construction in Malaysia is the sustainable construction requires more time and cost investment ranked as number 1 with the mean of 4.94 and standard deviation 0.243. Thus, this study has provided the initiative to overcoming the barriers in sustainable construction is significant to ensure the contractor can acquire the benefits from implementing sustainable construction. From the study, it is suggested that further research should be made in identifying initiatives to promote the application of sustainable construction among contractors in Malaysia to adapt sustainable lifestyle in the country.
