Key points and control measures of green building supervision?

According to "Zhejiang Green Building Regulations": "The supervision unit should supervise whether the construction unit carries out the construction according to the construction drawing design documents and mandatory standards for green buildings, and whether it adopts energy-saving and emission-reduction measures and environmental protection measures", which obviously puts forward higher requirements for supervision. However, at first glance, several concepts related to and similar to "green building" are almost the same, but their meanings are actually different. In order to do a good job in supervision, combined with the provisions of relevant codes and documents, several related terms and concepts such as "green building" are summarized as follows:

1. 1 green building

Green building refers to a civil building that meets the requirements of "four festivals and one environmental protection", provides people with healthy, applicable and efficient use space and lives in harmony with nature during the whole life cycle of the building.

1.2 green building

Green construction refers to the construction activities of "four festivals and one environmental protection" through scientific management and technological progress on the premise of ensuring basic requirements such as quality and safety.

1.3 green building construction

Green building construction refers to the construction activities of "four festivals and one environmental protection" of green building through scientific management and technological progress in order to achieve the construction goal of green building under the premise of ensuring basic requirements such as quality and safety.

1.4 green construction supervision

Green construction supervision refers to the supervision and management of the green construction of the construction project by the engineering supervision unit in the construction stage according to the current laws and regulations, relevant standards of green construction and the construction contract of the construction project, so that the construction can save resources to the maximum extent, reduce the negative impact on the environment and realize the service activities of "four festivals and one environmental protection".

1.5 green building supervision

Green building supervision means that the project supervision unit is entrusted by the construction unit to supervise and manage the green building in the construction stage according to laws and regulations, construction standards related to green buildings, survey and design documents and contracts, so as to save resources to the maximum extent, reduce the negative impact on the environment and realize the service activities of "four festivals and one environmental protection".

2, the characteristics of green building

2. 1 Green buildings have a life cycle.

To achieve the goal of "four festivals and one environmental protection", buildings are required to consider how to reduce resource consumption, live in harmony with and protect the surrounding environment, maximize resource conservation and reduce negative impact on the environment, comprehensively consider construction costs, use costs and maintenance costs, and reflect the life-long investment of green buildings.

2.2 Green buildings are environmentally friendly.

Green building requires saving resources, protecting the environment, recycling and minimizing pollution. Therefore, when designing, building and putting into use, clean and renewable energy (solar energy, wind energy, hydropower, geothermal energy, etc. ) Interference with the natural environment should be avoided or minimized as much as possible.

2.3 Green building is comprehensive.

In the design and construction of green buildings, factors such as quality, safety, environmental impact, energy consumption, water consumption, material resources and indoor environmental quality should be comprehensively considered, so as to coordinate with the surrounding environment, destroy and restore the original natural state as little as possible, make full use of renewable energy and save material consumption. In addition, green building will involve education, design, architecture, building materials manufacturing, construction equipment production, property management, decoration, energy production and various municipal infrastructures.

2.4 the economy of green buildings

Through reasonable design and construction organization, green buildings can minimize energy consumption, reduce repetitive work, make full use of natural resources and renewable resources, and reduce the cost of the whole life cycle, which embodies the economy of green buildings.

3, the main content of green building supervision work

The methods, procedures and means of supervision work are not much different from ordinary supervision work, but the contents of supervision work will mainly focus on some activities related to green buildings, including: compiling supervision plans and detailed rules related to green buildings, reviewing whether the construction organization design (scheme) is related to green buildings, materials (components and equipment) used, and acceptance of concealed works. Meet the requirements of green building, and ensure the realization of the goal of green building through supervision;

3. 1 When reviewing the green building construction organization design (special construction scheme) submitted by the construction unit, in addition to the procedural and targeted review, the contents should also be emphatically reviewed, including:

3. 1. 1 project overview. It should include: project site selection, project characteristics (including earthwork and foundation engineering, foundation and main structure engineering, building decoration engineering, building thermal insulation and waterproof engineering, electromechanical installation engineering, demolition engineering), construction environment, project contractor, etc.

3. 1.2 Compilation basis.

3. 1.3 green building construction goal, green construction goal. Should check whether it meets the design and contract requirements;

3. 1.4 Project management organization and responsibilities.

3. 1.5 technical measures for green building. It should include the technical measures taken in five aspects: land saving and outdoor environment, energy saving and energy utilization, water saving and water resource utilization, material saving and material resource utilization, and indoor environment.

3. 1.6 technical measures for green construction. It should include six technical measures: construction management, land saving and land resource protection, energy saving and utilization, water saving and water resource utilization, material saving and material resource utilization, and environmental protection.

3.2 The project supervisor shall check the implementation of the technical measures of "four sections and one environmental protection" for green buildings, make corresponding inspection records and establish a ledger.

3.2. 1 Establishment of construction management system and organization, formulation of environmental protection plan and occupational health and safety management plan, and implementation of technical measures in land use, outdoor environment, transportation facilities and public services, site design and site ecology.

4, green building supervision control points and countermeasures.

4. 1 design stage

According to the requirements of the Evaluation Standard for Green Buildings (GB/T50378- 20 14), the evaluation indicators of green buildings related to this project should be decomposed in the design stage and used as control items, which must meet the requirements; The scoring indicators are divided into "general items" and "preferred options", which are controlled according to the index values required by the declared grade, namely, one star (★), two stars (★ ★) and three stars (★★★ ★), and the determined indicators are included in the design task book. As the design requirement of green building, the supervisor should review the comprehensiveness, completeness and suitability of relevant indicators of green building in the task book. The determined indicators are not only the basis of design work, but also the basis for reviewing design results. At the same time, assist the owner to:

4. 1. 1 pre-design. Mainly review whether the geological exploration report and corresponding documents meet the requirements to determine whether the site is threatened by floods, mudslides and radon-containing soil, and whether there are electromagnetic radiation hazards, fires, explosions, toxic substances and other hazards within the safety scope of the proposed site; At the same time, the environmental impact assessment report should be reviewed to ensure that the environmental noise is within the specified range.

4. 1.2 Construction drawing design stage. It is mainly to check whether the indexes of sunshine, lighting, ventilation, sound insulation and thermal engineering of the building meet the requirements, and whether recyclable materials, local renewable energy, high-performance materials, various water resources and non-traditional water sources are fully utilized. At the same time, it is necessary to check whether the structural selection, electrical design, HVAC design and water supply and drainage design are reasonable and comprehensive, whether natural lighting and artificial lighting are organically combined, and whether they have adverse effects on human health and the environment.

4.2 Construction stage

Before the project starts, the first site meeting, supervision disclosure and other forms should be used to do a good job in the disclosure of quality, safety, progress and cost control, supervision procedures and methods in the construction process, and clearly require the construction unit to prepare a targeted green building construction special plan. The project supervision department should combine the requirements of green construction guidelines and green buildings in the design documents. Review the special plan for green building construction, inspect the relevant materials and equipment, sample the materials, components and equipment that need to be inspected, inspect the construction process in stages, and accept the partial projects.
