Abstract

As we know, building has significant impact on the energy use and the environment. Energy efficiency in office building located in tropical climate has much discussion in the building industry. One of the milestones in building construction is the development of nZEB (near netzero energy building). It is a complex concept building that can generate as much energy as it consumes, and the energy comes from renewable resource. The nZEB requires a wide range of technologies, systems, and solutions with varying degrees of complexity and sophistication, depending on the location and surrounding environmental conditions. In this paper, the design strategy to achieve nZEB like the active energy efficiency measures and passive energy design are discussed. Active design which are energy efficient are heating, ventilation, airconditioning (HVAC) system, radiant slab cooling, energy efficient office equipment etc. For passive design it involves the building orientation, thermal insulation, building envelope and vegetation on building etc. In this research, two administrative building in Malaysia which have been constructed using nZEB concept i.e. Ministry of Entrepreneur Development Office Building and Energy Commission Diamond Building are selected as cases to study the energy efficiency and energy generating features. Besides that, the benefits of nZEB i.e. environmentally friendly, increase living quality as well as high resale value, and challenges of operating a nZEB like the reason behind the difference energy performance as predicted and in actual operation of nZEB will be discussed to get deeper understanding. The methodologies used for this paper is qualitative method including methods like documentation, direct observation, archival records and interviews.
