Summer cooling, winter heating, lighting, living kitchen energy (natural gas), and domestic hot water supply are the main energy needs of the Olympic venues. The Beijing Olympic venues use a large amount of solar energy, wind energy, geothermal heat and ground source heat pumps to provide green energy supply totaling about 64.5 million kWh/year. In the total construction area of ​​the Olympic Games, 1.97 million square meters, more than 500,000 square meters will use green energy. The proportion reached 26.9%, achieving the goal of more than 20% of the Olympic project's green energy supply, and reducing CO2 emissions by 57,000 tons/year. Solar photovoltaic grid-connected power generation system will be built in 7 venues, with a total installed capacity of more than 480 kilowatts and a power generation capacity of 580,000 kWh/year, equivalent to saving 384 tons/year of standard coal, reducing CO2 emissions by 1,113 tons/year, while using solar energy. 90% of the Olympic venues provide lawn lighting and street lighting to provide all the domestic hot water supply for the Olympic Village; Beijing's first large-scale wind farm Beijing Guanting Wind Farm will complete an installed capacity of 50,000 kilowatts by the end of 2007, which will be to Beijing. Provide 100 million degrees of green electricity. By 2008, 56 wind power plants will be built in Beijing and its surrounding areas, generating wind power supply capacity of 3.2 billion kWh per year.
Efficient energy utilization technologies such as building energy-saving and ground (water, air) source heat pump, semiconductor lighting, cold and heat power supply, saving electricity of about 260 million kWh/year, reducing CO2 emissions by 230,000 tons/year; The latest design standards of 65% energy saving and 50% energy saving in public buildings, including 1.88 million square meters of public buildings and 1.123 million square meters of residential buildings, can save a total of 75,000 tons of standard coal per year; the Olympic Village uses a regenerative water source heat pump system to provide winter heating. In the summer, it can save about 3,600 tons/year of standard coal. At the same time, the green lighting of the Olympic venues uses a new generation of semiconductor lighting with longevity, energy saving, safety, environmental protection, rich colors, and miniaturization. In the landmark buildings and areas such as the National Aquatics Center and the Olympic Center, the implementation of IPv6 digital network lighting control system and semiconductor lighting demonstration project will save 70% of landscape lighting energy and extend the service life of lighting lamps by dozens of times.
