Natural light intake

Research lab filled with soft dispersed light

Using the light shelf and recycled wood vertical louvers installed on the western side, uncomfortable direct light can be screened almost completely without lowering blinds, making it possible to enjoy the superb views to the west. Light reflected from the light shelf is converted to soft dispersed light by means of the milky glass in sections between the buildings, traveling along the sloping ceiling into the back of the research space. Reflected light is also introduced from the corridor side via the atrium, assuring a natural light intake from both east and west sides.

Natural ventilation

Inside the atrium

Taking advantage of the suction effect that arises when prevailing winds from the west of the site flow along the cross-sectional shape of the building, natural ventilation is provided for the entire facility via the atrium. By securing ample space for hot air to gather at the top of the atrium, we ensure that the zone of temperature increase due to sunlight inside the atrium does not descend to the residential zone.
