Green building evaluation index

The evaluation index system of green building consists of five categories: safety, durability, health and comfort, convenience of life, resource conservation and environmental livability. Each category includes "control item" and "score item", and "improvement and innovation plus item" is set.

Building safety is the most basic premise for people to use buildings, and building durability is an important way to improve the service life of buildings, reduce renovation costs and reduce resource consumption. This index puts forward specific requirements for the safety and durability of green buildings.

Indoor health and comfort is an important guarantee for people to use buildings normally, reduce the risk of diseases and improve people's work and study efficiency. This index puts forward specific requirements for green buildings to achieve healthy and comfortable performance from four aspects: indoor air quality, water quality, acoustic environment and light environment, and indoor hot and humid environment.

Perfect living facilities can make people's work and life more convenient and obviously improve their quality of life. The index puts forward specific requirements for green buildings to achieve convenience in life from four aspects: travel and accessibility, service facilities, intelligent operation and property management.

The resource saving index puts forward specific requirements for green building to realize resource saving from four aspects: land saving and land use, energy saving and energy utilization, water saving and water resource utilization, and material saving and green building materials. Environmental livability index puts forward specific requirements for green buildings to achieve environmental livability from two aspects: site ecology and landscape, outdoor physical environment.

Improve and innovate indicators, encourage green building enterprises to give full play to their respective advantages, and adopt advanced, applicable and economical technologies, products and management methods at all stages of construction to innovate and develop green buildings.

Classification of green buildings in China

The standard divides the grade of green building into four grades, namely basic grade, one-star, two-star and three-star grade. This consideration is mainly to connect with some mainstream green building evaluation standards in other countries in the world. Richer grade setting can give more buildings the opportunity to participate in the evaluation of green buildings and better promote the wide promotion of green buildings.

Add "basic level", the provisions of green building evaluation meet the requirements of "control items", and all the control items of basic level will be included in 39 full-text mandatory engineering specifications being compiled. It is estimated that around 2025, new buildings will fully meet the green building standards; Increasing grass-roots units also takes into account the imbalance between regional development and urban and rural development.

In addition, green buildings are divided into four grades, which is also the common practice of major international evaluation standards for green buildings, and is conducive to international cooperation and exchanges in the field of green buildings.
