Nippon innovative technology: it can reduce the total building energy consumption by up to 22% and alleviate the heat island effect
According to statistics, China's existing building area is 40 billion square meters, most of which are high-energy buildings, and nearly 2 billion square meters of new buildings are built every year, of which more than 95% are still high-energy buildings. Building energy conservation has become one of the important links in building a low-carbon economy, achieving the goal of energy conservation and emission reduction and maintaining sustainable economic development.
At the same time, due to the frequent occurrence of greenhouse effect and extreme climate, the temperature continues to rise in summer. The roofs and exterior walls of buildings exposed to solar heat radiation need to absorb and store more heat. A large range of air conditioning and refrigeration will also consume a lot of electric energy, causing the heat island effect.
Based on this, Nippon has developed the "cold wall" technology by introducing special high heat reflection coefficient raw materials and innovative formula design. With the support of the "cold wall" technology, Nippon excellent energy reflective thermal insulation coating can greatly improve the reflection of near-infrared and visible light in the sun, reduce the solar radiation energy absorbed by the wall surface, and directly block the heat outside the wall, Effectively reduce the total building energy consumption by 5% - 22%, create a comfortable indoor environment, reduce the utilization rate of air conditioning and prolong the building life.
Comparison of thermal insulation effect between ordinary coating external finish and reflective thermal insulation external finish
Most contemporary buildings are made of reinforced concrete, and the characteristic of concrete is that it can store a lot of heat, so the thicker the wall, the more heat it absorbs and stores. Especially in the high temperature in summer, the wall absorbs a lot of heat from the sun. At night, the heat still can't dissipate for a long time. Even if the indoor air conditioner is fully turned on, it can't quickly restore the indoor comfort, which virtually increases the energy consumption.
The external wall of the building is painted with Nippon excellent energy reflective thermal insulation coating with the function of "cold wall". Through the high reflection and high radiation of sunlight and heat, the heat is blocked outside the wall, so as to greatly reduce the wall surface temperature and indoor temperature, effectively reduce the refrigeration energy consumption and improve the building comfort.
Based on Nippon's "cold wall" technology, Nippon's R & D team has successively developed a series of excellent reflective and thermal insulation products, including reflective and thermal insulation flat coating, reflective and hot water in water, reflective and hot water in sand and reflective and thermal insulation real stone paint, creating a full-system and full-color reflective and thermal insulation coating products covering the mainstream effect of exterior walls, It meets the rich needs of architectural designers and customers for color selection and effect of reflective thermal insulation coatings.
Due to the limitation of technology and raw materials, the color effect of traditional reflective thermal insulation coatings is often limited to light color and flat coating effect. Nippon used cold wall technology, developed waterborne silicone acrylic emulsion sand containing colorful system and combined with the latest "particle gel fixing technology" to develop the Nippon energy reflective thermal insulation finishing coating, which has achieved both insulation and high-end stone effect, and solved the problem of slow construction, poor effect and high cost in the field of thermal insulation.

Reducing energy consumption, increasing effect, reflective heat insulation and texture coating system is becoming the most preferred energy-saving texture exterior wall solution for buildings. At present, the reflective heat insulation coating supported by Libang "cold wall" has been widely used in new buildings by Vanke, Biguiyuan, investment promotion and other famous real estate. In addition, Nippon reflective thermal insulation coatings are also widely used in many public buildings, such as schools, hospitals, municipal venues and industrial plants.
