China Construction Technology is building an assembly + passive energy-efficient building

- Jun 04, 2019-


Currently, “passive buildings” and “green buildings” have become hot words in the field of energy-efficient buildings. “Passive ultra-low-energy green building” is different from the general structure in that it can realize energy-saving and environmental protection and green livability through special design of both the building itself and electromechanical installation.

"Green + energy saving" design concept

“In order to ensure the tightness of the building, we have developed green building materials. The outer wall of the floor is composed of 'five-in-one' wall panels, which not only has good insulation effect, but also has self-cleaning function.” Zhongjian Technology Comprehensive Building Project Technical manager Hu Kuanhuai said. Taking into account the climatic characteristics of the Changsha area, the design of the complex will minimize the energy consumption of building heating and cooling, and make full use of the solar heat and energy storage technology to truly achieve the effect of “natural ventilation”.

At the same time, the complex has achieved ultra-low energy consumption design goals by adopting a large number of passive technical measures such as high-quality external protection structure, effective shading system and natural ventilation. “In order to achieve warm winter and cool summer, we have designed an efficient energy recycling system, which ensures the overall heating of the building through solar absorption air conditioning and ground source heat pump technology, and realizes the efficient use of solar energy and geothermal energy.” Li Qiang, deputy manager of the building project, said.

The entire Zhongjian Science and Technology Industrial Park Complex uses renewable energy such as solar energy and geothermal energy. Compared with traditional buildings, it saves 160,000 kilowatts of electricity every year, saves 160,000 electricity bills, and saves nearly 60 tons of standard coal every year, reducing carbon dioxide emissions. Ton.
