1. Reduce total energy demand
According to statistics, in developed countries, air-conditioning heating energy consumption accounts for 65% of building energy consumption. At present, the recent growth rate of energy for heating, air conditioning and lighting in China has been significantly higher than that of energy production. Therefore, reducing the cooling, heat and lighting energy consumption of buildings is an important part of reducing the total energy consumption of buildings. Generally, the following can be Several aspects are achieved.
1.1 Architectural Planning and Design
In the face of global energy and environmental issues, many new design concepts have emerged, such as micro-row buildings, low-energy buildings, zero-energy buildings and green buildings. They essentially require architects to proceed from the overall integrated design concept. Energy analysis experts, environmental experts, equipment engineers and architects work closely together. In the planning and design of buildings, according to the influence of a wide range of climatic conditions, focusing on the specific environmental climate characteristics of the building itself, the use of the natural environment (such as outside air, rain, lakes and greening, terrain, etc.) to create a good building interior micro Climate to minimize dependence on construction equipment.
The specific measures can be summarized into the following three aspects: rational selection of the address of the building, and reasonable external environment design (main methods: arranging trees, vegetation, water surface, rockery, wall around the building); rational design of the building shape (including the overall construction) The determination of the volume and the orientation of the building) to improve the existing microclimate; the rational architectural design is a key part of making full use of the outdoor micro-environment of the building to improve the micro-environment of the building interior, mainly through the structural design and construction of the various components of the building. A reasonable separation of the interior space is achieved. At the same time, the relevant software can be used to optimize the design, such as using the architectural shadow simulation in Tianzheng Building (II), assisting the design of the building orientation and the roads, greening, outdoor leisure space and CFD software of the residential community, such as: PHOENICS, Fluent, etc. Whether the air flow inside and outside is smooth.
1.2 Enclosure structure
The components of the building envelope (roof, wall, foundation, insulation, sealing material, doors and windows, shading) are designed for building energy consumption, environmental performance, indoor air quality and the visual and thermal comfort of the user. Have a fundamental impact. Generally, the cost of the enclosing structure is only 3% to 6% of the total investment, while the energy saving can reach 20% to 40%. By improving the thermal performance of the building envelope structure, outdoor heat can be reduced into the room during the summer, and the heat loss in the room can be reduced in the winter, so that the building thermal environment can be improved, thereby reducing the building's cold and heat consumption. Firstly, improving the thermal performance of the components of the enclosure structure is generally carried out by changing the thermal properties of the constituent materials, such as the newly developed thermal diode wall in the European Union (low-cost sheet thermal diodes allow only one-direction heat transfer, A glass that can produce thermal insulation and thermal properties that vary with the seasons. Then, according to the local climate, the geographical location and orientation of the building, and based on the calculation results of the building energy consumption software DOE-2.0, the optimization design method of the enclosure structure is selected. Finally, assess the technical and economic feasibility of the various components and combinations of the enclosure to determine a technically viable and economical enclosure.
