Tokyo Establishes Energy-saving and Renewable Energy Standards
In order to further improve the energy-saving performance of facilities within Tokyo, Japan has established the "Tokyo Standard for Energy Saving and Renewable Energy." This new standard adds provisions promoting the adoption of energy-saving equipment such as LED lighting and high-efficiency air conditioning systems, as well as renewable energy sources.
The government will adopt renewable energies like solar power, solar heat, natural lighting, natural ventilation, and geothermal energy. In terms of equipment, it will also use cogeneration systems that efficiently utilize thermal energy and electricity, improving the efficiency of air conditioners, pumps, fans, and heaters, while introducing LED (light-emitting diode) lighting. Additionally, by combining occupancy sensors, appropriate brightness adjustment devices, daylight-linked control devices, and outside air cooling air conditioning systems, the optimization of air conditioning and lighting can enhance electricity-saving effects.
The implementation of the new standard is expected to reduce electricity consumption and carbon dioxide emissions by approximately 30%. Compared to the average for small and medium-sized office buildings in Tokyo, it could cut these figures by about 60%.
