As we all know, due to the rampant exploitation of human resources, renewable resources are becoming less and less. One day in the future, resources will always be used up. Nowadays, every country advocates green environmental protection. Such as energy-saving batteries, energy-saving buildings, etc. Strive to "take from nature and return to nature"

energy saving, that is, the recycling and reuse of materials, making full use of the natural conditions around the base, from construction, operation to demolition and reuse, all links do not pose a threat to the environment, so what is an energy-saving building? What are the evaluation standards for energy-saving buildings? Next, let me introduce you one by one

what is energy-saving building

energy-saving building refers to the low-energy building designed after following the basic methods of climate design and energy conservation, and studying the building planning zoning, groups and monomer, building orientation, spacing, solar radiation, wind direction and external space environment. Its main indicators are: building planning and plane layout should be conducive to natural ventilation, and the greening rate should not be less than 35%; The building spacing should ensure that each household has at least one living space, which can get full window sunshine for 2 hours in the cold day, etc

evaluation standards for energy-saving buildings

1. The design of energy-saving buildings should be implemented “ Adjust measures to local conditions ” The design principle of

here refers to “ Ground ” It mainly refers to the climate of the place where the building is located. Wuhan is a typical area with hot summer and cold winter. Its climate characteristics are mainly sultry in summer and wet and cold in winter. Therefore, the energy-saving buildings in Wuhan must adapt to the climate characteristics of Wuhan. We cannot copy the building types in cold areas, hot summer and warm winter and marine climate areas, nor can we copy the building types in mild climate areas with four seasons like spring

① buildings shall be arranged in a north-south direction as far as possible. Otherwise, it is necessary to strengthen the thermal insulation performance of the building envelope and increase the construction cost

② there should be good natural ventilation between buildings and indoor buildings in summer, and the surrounding layout type should not be adopted for buildings. Low rise buildings should be placed on the windward side of the dominant wind direction in summer (South); Multi room building in the middle; The high-rise building is arranged at the back (north direction), otherwise, the bottom floor of the high-rise building should be partially overhead and the natural ventilation between the building groups should be organized

2. The thermal design of the building's outer envelope should implement the principle of advance

the current building energy-saving design standard has a low level of prescriptive indicators for the thermal performance of the building's outer envelope, which is only the need to achieve the goal of 50% energy saving at the current stage. It is far from the requirements of comfortable buildings, and there is a big gap with developed countries. With the development of China's economy, the design standards for building energy efficiency will be revised in stages, and the thermal performance of the building envelope will be gradually improved. Due to the long service life of the building, it is difficult to implement energy-saving transformation of the existing building according to the new standard at that time. Therefore, the principle of advance should be implemented, especially in hot summer areas, the thermal performance indicators of the building's outer envelope (roof, outer wall, outer door and outer window) should break through the minimum requirements specified in the energy-saving design standards, and be appropriately strengthened. The calculated temperature of the inner surface of the roof and outer wall in summer should be controlled

3. Architectural designers should have a sense of social responsibility

every thing people in society do, they consciously or unconsciously assume a social responsibility for the society, especially for engineering design. The design unit and designers design a project. Since the construction of the project, the designer has begun to assume lifelong social responsibility for it. The scope of Engineering responsibility is wide, and the responsibility is significant, and the time of responsibility is long (until the end of the design service life). Because energy is not only the driving force of China's strategic material and economic development, but also the necessary condition for the survival of future generations. Building energy conservation is a major event to implement the national energy conservation law and sustainable development strategy, the designers of energy-saving buildings actually assume a social responsibility involving the national development strategy and the survival conditions of future generations

conclusion: what are the evaluation standards for energy-saving buildings? I believe you are very clear after reading the above content, because the scope of Engineering responsibility is wide and the responsibility is great. Building energy conservation is a major event in implementing the national energy conservation law and sustainable development strategy
