Low Energy Buildings

The development of low-energy buildings is an important initiative to achieve carbon peaking by 2030 and carbon neutrality by 2060. According to the data of the relevant papers, if all the northern urban and rural buildings in China adopt passive ultra low energy building technology, it can save about 350 million tons of coal for heating and reduce about 900 million tons of carbon dioxide emissions each year. It’s of great significance to achieve the goals of “peak carbon dioxide emissions” and “carbon neutrality”. Starting from four key technologies for low-energy buildings, explanation and analysis the energy-saving methods for low-energy buildings, It also presents the challenges and suggestions for the development of low-energy buildings in China.

Passive Houses

In recent years, ‘passive house’ is an increasingly well-known word, and has gained rapid popularity and application in Europe and other developed countries. Currently, residential passive house is growing at 8% annually in Europe. With its low energy consumption and ultra-high comfort, it is acclaimed as the most promising energy-saving substitute of conventional residences of this century. The passive houses in Hamburg Germany use 75% less energy than the normal low-energy buildings, more than 90% less than conventional German buildings [1]. As reported by the National Conference of Green Building Materials and German Passive House Technology held from 22nd to 25th April 2014, passive house will certainly become the mainstream building in the country in the next three to five years.

Reduce Carbon Dioxide

Climate change is becoming a highlight of the world. As the world's second largest CO2 emission country, China faces increasing pressure. Energy consumption and utilizing is the major source of CO2 emissions. Optimization of the regional energy configuration can not only reduce energy consumption, but also reduce carbon dioxide emissions. Thus, it will achieve energy conservation and sustainable development. Based on the Eco-city constructed by China and Sino-Singapore, this paper calculates the regional energy-saving under the requirement of existing Energy Conservation Code, plans its energy saving quantity by taking some measurements and then predicts the carbon dioxide emission reductions. The result shows that using effective measures to save energy can reduce 227772t carbon dioxide emissions. Using renewable energy and energy saving measures will reduce 371414t CO2, which has a striking effect. So changing energy structure and using renew energy are main measures to reduce CO2 emission.

And Performance

Insulation systems: an insulation shell of building creates terms for energy saving, reduction of carbon dioxide emissions, natural environment preservation. And it is pressing question of modern construction. The concepts of green building take into account ecology and social protection in processes of work planning and performance, including energy saving.
