Heat barrier is the first protective layer against heat. Not only does it minimizes the heat gained by buffer spaces, it also functions as fenestration to allow natural ventilation as the Zone.Zone House focuses on passive solar design.

Why not incorporate plants into the heat barrier design? Plants absorb light and carry out photosynthesis, providing oxygen for the internal living environment, while shading the buffer zones from direct sunlight. Indoor Environmental Quality (IEQ) can be improved at the same time, as these plants are present in sight at every inch within the Zone.Zone House. They filter  air flowing into the internal living spaces and reduce noise produced by the street in urban environment.The idea of vertical farming on heat barrier is being explored as well. Furthermore, by taking advantage of the proposed site located at the end lot, this ''plant-filled'' heat barrier on the facade promote green building design to the public or passer-by at Jalan Raja Chulan.
