Examining the Influence of Passive Design Approaches on NZEBs: Potential Net Zero Healthcare Buildings Implementation in Malaysia

Nowadays, net-zero energy buildings (NZEBs) concept has gained considerable attention not only between the developed countries, but also among the developing countries including Malaysia. The rapid development in Malaysia, especially in the construction of healthcare buildings needs to be given due attention since these developments lead to all sorts of environmental problems. As the number of healthcare buildings increases, the energy consumes to operate these buildings will increase. The consequences of uncontrollable energy consumption may result in the increased volume of carbon dioxide emissions as well as depletion of natural resources. Thus, NZEBs has emerged as a proactive concept to confront with these issues. Therefore, the purpose of this paper is to examine the influence of passive design approaches on NZEBs as well as the potential of net zero healthcare buildings implementation in Malaysia based on a review of the existing literature and by utilising semi-structured interviews with 3 experienced architects. The result of this paper indicates that there are four main passive design components has strong influences on NZEBs which are building orientation, shading devices, ventilation, and thermal insulation. These practices are being actively practiced in Malaysia construction industry; thus, it shows that net zero energy healthcare buildings are potential to be designed in Malaysia. The study has gone some way towards enhancing our understanding of the significance of passive design approaches towards net zero healthcare buildings for future implementation in Malaysia context.
