Abstract

Sustainable architecture in passive mechanisms is seen as cost-effective and value–engineering principles that contribute to sustainability. The aim of the project was to develop a low energy toyyiban environment for a food testing lab complex. Environmental analysis was observed on the coupling of the waterwall with thermal mass system located at the main lobby of the National Centre for Food Safety in Sepang. A fieldwork measurement was conducted and acquired for the Computational Fluid Dynamics (CFD) ANSYS Fluent simulation process. It was found that the coupling of waterwall with thermal mass will result in 4˚C to 8˚C reduction to the indoor temperature under hot humid climate conditions when the outdoor temperature rises to 31˚C without resorting to any mechanical cooling. The results also demonstrated that the exploitation of low mean airspeed of 0.5 m/s provides a significant contribution to decrease the indoor temperature. Low mean airspeed provides ample time for the evaporative cooling of the indoor environment to become more efficacious and cooled air to circulate within the premise boundary, this is then again work if cross-ventilation strategy is adopted at the same time. The final shape of the central lobby and entrance is a pyramidal conical shape that mimics the ‘Tudung Saji’. This combines the strategy of chilled water walls and blowers in order to couple passive measures with daylighting through skylights. The paper features not only the design aspects and process, but also the low energy index of the overall complex thus upholding the concept of sustainable architecture and toyyib environment.
