The development of energy risk framework for retrofitting project

Energy demand in existing building growths every year compared with new building. The growth of energy consumption on existing building is significantly soaring throughout every year due to the degradation of energy efficiency and near-end life expectancy of building components. Energy retrofit is proven to improve energy efficiency at the expense of numerous risks as early in pre-construction project. Thus, the influences of risk facing by stakeholders to achieve optimum design strategies granting a huge effect in retrofit project. This research aims to address risks in retrofit project during pre-construction stage by determining the potential risk factors and the relationship with the retrofit elements. This research used convergent-parallel mixed-method within the context of qual-quan research design to administer semi-structured interviews and questionnaires to obtain information from internal stakeholders. With the aid of Computer-Assisted Qualitative Data Analysis Software (CAQDAS), Atlas.Ti version 7, the qualitative data were coded, categorized, and analysed obtained from six respondents. The Statistical Package for Social Science (SPSS) were used for analysing quantitative data collected from 66% of respondents out of 198 samples. The analysis revealed that two critical risk factors was found under planning and design phase. In planning phase, the most critical factor is related with the tenant cooperation in post-planning. The contribution of this risk is influences by the policies, regulation, human factor, and uncertainty factor elements. Likewise, the risk in design phase that require critical concern is related with inaccurate of energy model. It shows that the risk is influences by technologies, uncertainty factor and client expectation elements. The highlighted risks demonstrate the correlation with the retrofit elements to achieve optimum energy efficiency design through developed framework model. The develop framework model was validated across ten respondents and proven to assist construction industry to achieve optimum design strategy by assessing the highlighted risk factors and elements. The validation process in framework is conducted through expert panel in retrofit project and analyse using Krippendorff alpha reliability method

Kerja baikpulih bangunan komersial yang terbengkalai di kawasan Melaka Tengah

Industri pembinaan merupakan satu sektor yang menjadi pemangkin kepada pertumbuhan sosio-ekonomi dan sebahagian besar sumbernya digunakan kearah pembangunan yang pesat dalam pentadbiran negara. Projek-projek mega seperti Kuala lumpur internationa airport (KLIA), Pusat pentadbiran kerajaan di putrjaya dan banyak lagi pembinaan bangunan komersial yang menjadi tanda aras perkembangan yang memberangsangkan. Selain dari itu, pembangunan bagi sesuatu kawasan menyebabkan pertambahan penduduk. Ini menunjuk industri binaan merupakan salah satu sektor yang menyumbang dalam pembangunan dari aspek sosial dan ekonomi kepada sesuatu kawasan. Walaupun banyak teknologi dalam industri pembinaan telah digunakan pada masa kini, ia masih lagi tidak dapat mengawal kehadiran bangunan yang terbiar di Malaysia dan kesan kewujudan bangunan terbiar itu mengakibatkan kerugian kepada pelbagai pihak dan mengancam keselamatan penduduk sekitarnya

The Investigation of Energy Risk in Pre-Construction Stage: A Qualitative Approach

The energy demand growth every year for existing building due to the natural lifecycle of the building performance. Systematic strategy in retrofitting is proven to revamp the energy building performance. However, the retrofitting process is facing several of unknown risk as early in pre-construction stage to achieve optimum energy efficiency design strategy. The risk requires strategic assessment to minimize the impact towards the efficiency level in retrofitting. This study aims to examine the risks and the potential impact towards design strategies by conducting a semi-structured interview from six internal stakeholders in the retrofit project. The result derived from the interview revealed that there are 13 of major risks involve in retrofit project and divided into planning stage and design stage. All the risks are proven to provide a potential impact towards energy efficiency design strategies
