Modeling Critical Success Factors Influencing Energy Management Performance towards Sustainability in Malaysian Public Universities Using PLS-SEM Approach

Energy usage in Malaysian universities has increased constantly. Frequent commentaries in the literature have stated by identifying critical success factors (CSFs) and continually measured using Key Performance Indicators (KPIs) will ensure successful effective performance for the organization. However, no one has yet tried to define in a formal way these relationships. Thus, this study is carried out to identify the CSFs and determine the relationship of identified CSFs with the KPIs, indirectly developing the CSFs structural model. The conceptual model is composed by exogenous latent variables (LVs) namely Top Management Support, Comprehensive Energy Management Team, Awareness, Strategic Maintenance Management and Good Relationship of Stakeholders and one endogenous LVs which is KPIs to achieve the goals of energy management performance improvement. The study presents empirical evidence from a survey of five research universities in Malaysia, where 280 sets of questionnaire were analyzed using PLS-SEM to test the conceptual model. The indicators for these enablers and result criteria were extracted from the past literature and by a pilot study. The findings show that the comprehensive EM team has the highest path coefficient (s value) which has the most significant relationship on KPIs (s=0.195; t-value=2.701) followed by strategic maintenance management (s=0.187; t-value= 2.661); awareness (s=0.149; tvalue=2.336); top management support (s=0.106; t-value=1.963); and the least is good relationship of stakeholders (s=0.104; t-value=1.443). From the findings, this study provide insight to management team in universities to focus on the implications from these four constructs to improve the energy management performance within an organization.

A Review on Tropical Green Roof Maintenance Practice of High-Rise Residential Buildings

The Malaysia Plan is slowly moving towards the green growth for sustainability and resilience to develop a green environment and culture. Few initiatives have been developed, and one of them is with the development of Green Building Index (GBI) as Malaysia’s green building rating system where the green roof is also the important criteria needed to achieve green status. Hence, the green roof has received significant attention in Malaysia over the years especially in the environmental performance of the system. However, the maintenance management of green roofs is often being neglected and does not being looked in. There are also lack of scientific research regarding the maintenance management practice of green roof in this tropical climate. This research is carried out to assess the green roof maintenance practice in high-rise residential buildings and to analyse the guidelines and codes being applied in other developed countries. The research has been conducted through an extensive reading on the literature from journals and articles. From the literature reviews, there are few successful green roof projects in high-rise residential buildings located in urban cities of Kuala Lumpur, and the current maintenance practice of green roofs is also being analysed. Generally, it can be concluded that maintenance works in high-rise residential buildings are being out-tasked to the related teams in order to maintain the green roof as well as the building in a proper way. A better maintenance management practice will inspire greener roof implementation in this country in future.
