In this rapid urban development, buildings face many environmental challenges in terms of energy efficiency and the occupants’ health issues. Based on the statistics, buildings consume a large portion of world energy, approximately 37% of the total energy consumption or one-third of the world’s energy. In commercial buildings themselves, the biggest portion of the energy is from the lighting which consumed up to 20% of the total consumption. Hence, strategies in lighting design need to be figured out aiming to reach energy-efficient buildings towards net-zero buildings. Optimizing the use of daylighting, planning a building that is designed to fulfil its lighting energy needs, and switching the lighting’s electrical energy source into on-site renewable energy are some of the feasible strategies that could be implemented to create a lighting design to achieve the net-zero building. However, this post-pandemic situation creates a new challenge to the building design. Awareness must be raised concerning the health issue that covers many aspects, i.e. access to daylighting, illuminance level, and also access to the outside view. Unfavourable conditions in lighting such as inadequate illumination is known to have a negative impact on the user’s performance. Therefore, optimizing daylighting is a strategy to reach an adequate illuminance level. This strategy is beneficial yet important since exposure to sunlight could help to increase the covid-19 recovery rates. This paper studies the lighting design in terms of its contribution to achieve net-zero healthy in an adaptively reused building that functioned as education institution. The buildings were selected according to their post-occupancy performance evaluation after being adaptively reused. In this research, the observation was conducted both in the measurements of daylight area percentages, the illuminance level, the electrical energy consumed for artificial lighting, and the percentages of the area that have access to outside view. The findings show the performance of the adaptively reused building based on net-zero healthy parameters and followed by a design proposal to improve the performance.
