Working toward the Realization of Comfortable and Energy Efficient Spaces with Climate and Landscape-Utilizing Radiant Heating and Cooling
Scroll Down
When planning a building, it is necessary to examine the building site and formulate a plan rooted in the climate and landscape. This is a necessary process toward realizing sustainable buildings. There are no two building plans with identical building site conditions, and the same can be said for facility designs.
The radiant heating and cooling plan devised by Nikken Sekkei for the new Densan main office building is closely linked to the architectural plan, the lighting plan, the climate, and the landscape. Based on the example of the new Densan main office building, information will be presented here on logical radiant heating and cooling plans that make use of the climate and landscape.

The ceiling surface is cooled and the space is enclosed in radiant heat. The heat generating part of the lighting fixtures are disguised inside the ceiling to reduce variation in heat radiation. -
