What tests do green building projects need to do?

Need to test land saving and outdoor environment, energy saving and energy utilization, water saving and water resource utilization, material saving and material resource utilization, indoor environmental quality, construction management, operation management, etc., Langlv Technology provides comprehensive one-stop testing services to provide testing technical support for the development of green buildings.

1) Land saving and outdoor environment;

2) energy conservation and energy utilization;

3) water conservation and water resource utilization;

4) Material saving and material resource utilization;

5) Indoor environmental quality;

6) Operation management (residential buildings), comprehensive performance of the whole life cycle (public buildings).

See how many stars you are green building, open the drawings green building special article can understand. But regardless of the star rating, the following three categories must be tested:

1. Materials, including high-performance concrete and permeable bricks;

2. Noise, including indoor allowable noise, sound insulation and impact sound.

3. Lighting, including illuminance and power.

In addition, hotels, shopping malls and other projects with first-class air conditioning also need to test the air conditioning system. Projects in the main city of Chongqing generally also require testing of air, water quality, ready-mixed mortar, etc.

Unlike other testing by area, green building testing is based on the functional distribution to do the testing plan, so it is important to find a testing unit that understands the standards and specifications, and they can help you optimize the distribution and save testing costs.

With the large-scale development of green buildings in China from scratch, from less to more, from single to urban areas, from individual cities to the whole country, the corresponding green building technical standard system has also been continuously improved. Although everyone is talking about green buildings, can you clearly say, "What kind of building can be called a green building?" What tests do green buildings need to do?

There are not many people who have this problem. Today, the government Yuanjun from China's current implementation of the "green building evaluation standards.

GB-T50378-2014, take you to take a peek.

What is a Green Building?

In the "Green Building Evaluation Standard" GB T50378-2014 formulated by the Ministry of Construction in 2006 and revised in 2014, green building (greenbuilding) is defined as: saving resources (energy saving, land saving, water saving, material saving, referred to as "four sections") and protecting the environment to the greatest extent during the whole life cycle.

Buildings that reduce pollution (often referred to as "one environmental protection"), provide people with healthy, suitable and efficient use of space, and live in harmony with nature.

The whole life cycle here refers to the whole cycle process from the extraction of raw materials, the production of materials and components, planning and design, construction and transportation, operation and maintenance, and dismantling and treatment (disposal, recycling and reuse, etc.).

From the concept, it can be seen that the "green" in green building is not simply the degree of building greening, but emphasizes the economic benefits and environmental friendliness of the building. For example, the level of use of natural resources and the level of energy conservation; At the same time, the environmental benefits of the building are pointed out, such as whether it reduces environmental pollution and carbon dioxide.

emissions; In addition, the social benefits of the building are also taken into account.

For example, "healthy", "suitable" and "efficient".

Although the "Standard" also emphasizes the "four sections and one environmental protection" performance of the building. However, we also need to be clear: energy-efficient buildings are not necessarily green buildings, but green buildings must be energy-efficient buildings. Green buildings consider renewable energy on the basis of energy-efficient buildings.

The content of utilization, water saving, material saving, land saving, indoor environmental quality and intelligent control emphasizes sustainability.

What exactly do green buildings need to be tested?

We know the concept of green building, but what kind of standards does a green building need to meet? How do you evaluate it?

In fact, in the "Green Building Evaluation Standard" GB T 50378-2014, the evaluation of green buildings is given detailed standards from seven systems: land saving and outdoor environment, energy conservation and energy utilization, water conservation and water resource utilization, material saving and material resource utilization, indoor environmental quality, construction management, and operation management. Zhengyuanjun has prepared a list for everyone, so that everyone can have a clear understanding of the relevant testing items and standards that need to be met in each evaluation system of green buildings.

List of testing items related to the green building evaluation system.

No expiration date.

Green building certification refers to an evaluation activity that confirms the green building grade and carries out informational labeling in accordance with the "Green Building Evaluation Standards" and the "Technical Rules for Green Building Evaluation (Trial)", and in accordance with the "Green Building Evaluation and Labeling Management Measures (Trial)".

At present, the management documents on which green building certification is based are the "Management Measures for Green Building Evaluation Labels (Trial)", and the other is the "Management Measures for One- and Two-Star Green Building Evaluation Labels (Trial)". At present, the technical documents on which green building certification is based are "Green Building Evaluation Standards", "Technical Rules for Green Building Evaluation (Trial)", "Supplementary Instructions for Technical Rules for Green Building Evaluation (Planning and Design Part)" and "Supplementary Instructions for Technical Rules for Green Building Evaluation (Operation and Use Part)".

At present, there are special consulting institutions in China that can carry out green building certification, such as the Environmental Measurement and Control Optimization Research Center, etc.

Green building refers to a building that maximizes resource conservation (energy saving, land saving, water saving, material saving), protects the environment, reduces pollution, provides people with healthy, applicable and efficient use of space, and coexists in harmony with nature during the whole life cycle

The "green" analysis of "green building" does not refer to the three-dimensional greening and green building garden on the roof in the general sense, but represents a concept or symbol, which refers to a building that is harmless to the environment, can make full use of environmental natural resources, and is built under the condition of not destroying the basic ecological balance of the environment, which can also be called sustainable development building, ecological building, returning to nature building, energy-saving and environmental protection building, etc. There are six types of indicators in the green building evaluation system, which are divided into three-star, two-star and one-star from high to low

The interior characteristics of green buildings, the indoor layout is very reasonable, try to use natural materials, make full use of sunlight, save energy, and create a feeling close to nature for residents. With the goal of the coordinated development of people, buildings and the natural environment, while using natural conditions and artificial means to create a good and healthy living environment, we will control and reduce the use and damage of the natural environment as much as possible, and fully reflect the balance between taking and returning to nature.
