A green building focuses on increasing the efficiency of resources in term of energy, water and materials, while at the same time reducing the building impact on human health and the environment during the building's lifecycle. Green buildings are significant in operational savings and are able to increase workplace productivity. There are 909 registered green buildings project up to September 2019 in Malaysia. However, previous research indicated the success of green building in term of its performance is still in doubt and very much speculative. In fact, there have also been reports saying that green building fails to perform appropriately. Unfortunately, up until now there are no standard performance criteria and performance parameters to measure the green building performance in Malaysia. Thus, the aim of this paper is to present the findings of the research which identify the performance criteria and parameters of Post Occupancy Evaluation (POE) for green building in Malaysia. Fifteen (15) performance criteria and thirty-five (35) parameters were identified from the literature and validated by green building experts by using Content Validity Index. The finding identifies eleven (11) performance criteria and twenty-six (26) performance criteria to measure the green building performance through POE.

Life Cycle Costing (LCC) is deliberately known as a vital tool of construction process to optimise the whole life cost from the cradle to grave. LCC also considered as an important factor for a project to meet the equilibrium point of its strategic objectives. In order to implement the LCC, the procedures must undergo certain framework that enables comparative cost assessments to be calculated over specific duration and take account to relevant economic factors of initial, maintenance, operational, salvage value, discount factors, refurbishment and disposal costs. The aim of this paper is to appraise the benefits and barriers of Life Cycle Costing (LCC) practised in the construction industry of Malaysia among the consultant team. The objectives of this paper to explore the benefits and barriers of LCC faced by consultant team in construction projects. To comply with research objectives, a questionnaire survey and interview conducted among the consultant team in Malaysia. 57 participants responded for the survey conducted in this research. From the results, it appears that the implementation of LCC among the professional design team is still limited. Most of the consultant teams had a good knowledge on the processes of analysing LCC, the parameters to be included but still at minimal phases of implementing overall LCC procedures. The lack of reliable data of LCC founded as the main barriers in the Malaysian construction industry. Most of the respondents agreed that the benefit of LCC is the best way to consider the impact of all costs rather than only initial capital costs.

Every industry in a country is attempting to adopt all of the sophisticated technology that is available in conjunction with the advancement of technology. Abruptly, the establishment of the Construction Industry Master Plan (CIMP) has resulted in initiatives in the implementation of innovative approaches towards a sustainable construction environment via the Industrialised Building System (IBS). However, since the first IBS project in 1964 until today, IBS in Malaysia has been poorly accepted by construction parties due to a failure to adequately manage risks in IBS projects. Therefore, this study aims to focus the contractor's perspectives on the constraints of IBS implementation in order to assist contractors in their decision-making towards achieving effective project delivery. This study employed a quantitative approach. 85 questionnaires were distributed to local contractors (G1 to G7) that specialised in IBS project and 45 respondents the questionnaires. The results were analysed using the SPSS version 28 and descriptive statistical analysis. According to the results of the analysis, respondents agreed that the main five (5) constraints in implementation of IBS project were high initial cost, required high skilled labour, fluctuation of raw material price, lack of technology implementation and lack of financing.

Low adoption rate of Industrialized Building System (IBS) is an issue in Malaysian construction industry. Promoting its use is one of the initiatives of the Malaysian Construction Industry Transformation Program. As incentives have been offered by the government to the IBS adopters, low adoption rates are seen to be potentially due to demotivation of the contractors. This paper reports on the progress to date of a Ph.D. research project aimed on Supply Chain Management (SCM) framework development on to increase the IBS adoption by contractors. Supported by successful examples in the UK, there is confidence that the proposed SCM framework would bring positive results if implemented in Malaysia. Malaysian Public sector governance has identified the potential of SCM and aimed to utilize it through the Construction Industry Transformation Program 2016. A thorough review of literatures, survey and structured interview approach will be used to achieve the research objectives. The outcome of the research will be the groundwork that addresses the root demotivating factors and determine the SCM tools implementation to diminish them.
