Data centers consume substantial amounts of energy, so measures to counteract global warming are vital. These include conventional measures, such as advanced technology and expertise, as well as optimization techniques to reduce future impacts on the environment. As IT devices advance and change, so do the specifications for data centers. We use our vast experience in constructing data centers to develop facilities that meet the most advanced specifications. Our wide range of facility services for data centers include discovering sites suitable for constructing new data centers, as well as finding buildings that can be renovated for data centers. We also design and construct buildings for data centers that can adapt to various facility needs. We offer a variety of fundamental technologies for data centers, such as high seismic isolation performance, simulation technology, and enhanced security systems. We have extensive experience in designing and constructing computer centers and next-generation data centers in countries around the world.
