New Research Laboratory at the Tobitakyu Research Center of the Kajima Technical Research Institute


The project, in short

In the New Research Laboratory of the Kajima Technical Research Institute, a wide range of research on subjects such as countermeasures for global warming, biotechnology and renewable energies is conducted. More than ten leading-edge technologies that could help to reduce energy consumption and CO2 emissions in a step-by-step manner were applied to this building to ensure efficient use of energy and enable various renewable energy sources to be utilized. For example, a task-ambient air-conditioning system, an airconditioning system using renewable energy and so on, were applied to this building.

A task-ambient air-conditioning system was adopted for common corridor space that is called the “knowledge street”. In this space, indoor temperature is not completely controlled (ambient air-conditioning), but a task air-conditioning system can be used only at the necessary point like a meeting space. Using this system, an energy consumption of air-conditioning is reduced and at the same time, the thermal condition of a meeting space is kept comfortable.

As one of the green technologies, an air-conditioning system using renewable energy sources such as solar energy, sunlight, geothermal energy and underground water was designed and its performance was evaluated.
