At present, Seoul City is promoting the “Building Energy Rationalization Business Cooperation Program for LED Lightingâ€. The aim is to control climate change and the expansion of energy consumption.
In the past 100 years, the average temperature of the Earth has increased by 0.7 °C, and the rise of Seoul has been more than three times, about 2.5 °C. It is estimated that the CO2 emissions of Seoul City will increase by 1.6% annually between 2007 and 2020, and the energy use in 2020 will increase by 20.4% compared with 2000.
Therefore, in Seoul in 2007, the Seoul Declaration on Environmentally Friendly Energy was published. In the declaration, the “Building Retrofit Project (BRP)†was proposed, which converts existing buildings into environmentally friendly green buildings.
The Seoul City Hall and others are already promoting the effective use of energy. Energy efficiency measures were taken in 10 buildings and 66,000 457 square meters, reducing energy use by 13.3% and greenhouse gas by 14%. In addition, public buildings, schools and folk buildings are also advancing BRP. According to the blueprint for the development of lighting LEDs developed by the Korean government, Seoul City is also promoting the project of replacing lighting fixtures with LEDs. One of the goals of making 100% LED lighting in 2020 is one of them.
In order to save energy, Seoul City will invest 220 billion won by 2014. It is planned to make 10,000 buildings BRP in 2030.
All public facilities newly built in Seoul City have adopted a design that cuts energy use by more than 40%. The standard will also be used in all public facilities such as art galleries, hospitals, museums and children's facilities.
Currently, Seoul is building a new government office building. The new office building will set the annual energy consumption per m2 below 300 kWh, and will implement the reduction measures in stages of design, construction, completion and use.
