Seoul has launched a campaign to paint its city roofs with thermal-barrier paint to boost energy efficiency.
In the summer, roofs absorb heat which leads to temperatures increasing inside buildings, causing air conditioning units to operate inefficiently.
Thermal-barrier white paint works to block heat from increasing and makes the building cooler naturally.
The campaign “Cool Rooftop House” was launched with a rooftop party this weekend.
Applicants who live in houses with roofs can apply to have it painted for free by the city until September 8.
The local government will also start other campaigns to promote the project such as providing loan support for ‘cool roofs’ to construction companies.
Seoul is currently providing a total of 15 billion KRW (£8.57bn) in loan support to construct energy-saving houses and buildings.
