Reducing the burden on the global environment by saving energy and reducing CO2 emissions is an urgent issue shared by all humankind. It is important to promote green buildings as a quick and sure way to prevent global warming and achieve carbon neutrality. Energy consumption in buildings can be reduced by optimizing demand using the architectural energy-saving method and applying a high-efficiency mechanical system. It is also important to actively utilize renewable energy.
Specifically, promotion of energy saving and low carbonization of housing and buildings, formation of high-quality stock using existing buildings, energy management using AI, IoT, utilization of high-performance equipment, off-site renewable energy evaluation, CO2 emission evaluation during construction, etc. can be considered.
Regarding the reduction of CO2 emissions from green buildings, it is also important to make efforts in the process from the procurement of raw materials to transportation, processing, and construction, and from the perspective of the life cycle from the planning and design stage to operation, renovation, dismantling and disposal must be evaluated. Furthermore, in addition to the high performance of the hardware of the building, it is necessary to change the behavior of the workers and residents in the building so that they can use the building correctly.
Green buildings, which emit less CO2 throughout the life cycle of the building, are designed as business continuity planning that enables business continuity by using an independent energy system even for a certain period of time when the energy supply is interrupted in an emergency. There are also advantages. In addition, when the building is in operation, it can be expected to improve the thermal comfort and workplace productivity of building users. There is such a non-energy benefit.
