Bi House’s master bedroom on the top floor is protected from the heat by a grassed roof. For the two bedrooms on the middle floor which absorb the most heat in the afternoon, we create a deep trench separating the two spaces, extending from the ground floor to the terrace to create a ventilation space and a second wall to shield and reduce heat radiation from the outside directly into the building. Horizontally, there are two ventilation gaps located behind and above the staircase area between the house to help air flow and radiate heat for the whole house.
On top of that, green gardens surrounding the house also provide another boost of natural cool air. Besides heat control, lighting is also well thought out. Throughout the spaces, glass panes are flexibly used in many different positions to bring natural light into the building as well as minimize power consumption.
