Green building score calculation

Green building score calculation method: Q = (Q0+Q1+Q2+Q3+Q4+Q5+QA)/10.

Where q is the total score; Q0 is the basic score of control items; when all the requirements of control items are met, 400 points will be taken and assessed as the basic level; Q 1-Q5 is the score of five indicators in the evaluation index system: safety and durability, health and comfort, convenient living, resource saving and livable environment. QA is to improve and innovate scores.

After meeting the control items of each grade and the score of each grade item is not less than 30%, fully renovated and meeting the corresponding technical requirements, the scores of 60, 70 and 85 calculated according to the formula are rated as one-star, two-star and three-star green buildings respectively.

Green building, that is, under the condition of effectively meeting the basic functions of the building, uses the energy-saving and water-saving design of the building to realize the reuse of resources, and takes the environmental protection concept as the guide to minimize the damage to the ecological environment and create a good living environment for people.

Evaluation criteria and indicators of green buildings;

1. Safety and durability: the most basic prerequisite for the safe use of buildings. Building durability is an important way to improve building service life, reduce renovation cost and reduce resource consumption.

2. Health and comfort: an important guarantee for people to use buildings normally. A healthy and comfortable environment can 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.

3. Convenience of life: green buildings are required from four aspects: travel and accessibility, service facilities, intelligent operation and property management. Perfect living facilities are convenient for work and life, and the quality of life is obviously improved.

4. Resource saving: the requirements are put forward from four aspects: land saving, energy saving, water saving and water resource utilization, and material saving and green building materials. It is an inevitable trend to save consumption, reduce emissions and reduce costs.

5. Livable environment: it is required to be livable from two aspects: site ecology and landscape, and outdoor physical environment. Green buildings should live in harmony with the ecological environment. Reasonable planning of site ecology and landscape can reduce noise, light pollution and heat island effect and improve people's comfort.

6. Improvement and innovation: Encourage green building enterprises to give full play to their respective advantages, adopt advanced, applicable and economical technologies, products and management methods at all stages of construction, and innovate and develop green buildings.
