Today, low-carbon environmental protection is the most scientific and healthy concept of life. Building energy conservation is also the main direction of energy conservation and emission reduction in cities. Recently, the reporter learned from the city's urban and rural construction committee that this year the city will use energy-saving and emission reduction in the construction sector as a breakthrough, and strive to complete more than 10 green building projects. Through interviews with reporters, it has been learned that many projects have begun to apply energy-saving materials and promote energy-saving concepts.

New breakthroughs in building energy-saving and emission reduction It is reported that in recent years, energy-saving and emission-reduction have been the concept of urban operations advocated by the whole society. Energy-saving and emission-reduction of the construction industry is also a subject of extensive social attention. Island City building energy conservation has always been highly valued. A few days ago, the reporter was informed that this year the city will use energy-saving and emission reduction in the construction sector as a breakthrough, and strive to complete more than 10 green building projects, focusing on the ecological wisdom city and the Jimo and Jiaozhou regions, and continue to increase the scale of renewable energy construction in the city. Applied the work to complete the application of 3 million square meters of renewable energy building applications.

At the same time, it will also speed up the development of residential industrialization and promote the overall renovation of residential buildings. We will promote the application of recycled products for construction waste and strive to achieve breakthroughs in government investment projects. We will make comprehensive use of 4 million tons of construction waste. Improve the construction of energy monitoring systems for large-scale public buildings and government office buildings, complete 200 energy monitoring projects, promote energy contract management, and reduce public building energy consumption. Promote the energy-saving renovation of existing residential buildings and complete the reconstruction task of 1 million square meters. Although the concept of building energy conservation has been promoted for a long time, many people are still unfamiliar with this. For this reason, the reporter interviewed relevant experts to analyze this concept. It is understood that building energy conservation refers to reducing energy consumption as much as possible under the conditions of meeting the same needs or achieving the same purpose during the construction and use of building materials, housing construction and structures.

Energy-saving housing materials have "track"

The reporter also learned that there are many ways to save energy in buildings. Generally referred to as energy-saving housing, from the building itself, is to use certain insulation measures on the external wall of the building, so that the external hot temperature will not quickly enter the building, or make the indoor warm temperature not to Soon it will be lost, so that the indoor comfort will be greatly improved. In the absence of heating and cooling measures, the indoor temperature will be 2 to 3 degrees Celsius lower than other buildings in summer, 3 to 5 degrees Celsius higher in winter than other buildings, and residential The power consumption and other energy consumption have been greatly reduced. The construction of energy-saving residential buildings is mainly to make thermal insulation layers for roofs, exterior walls and exterior doors and windows. Roofing can use extruded board as insulation material. The reporter visited and learned that the most widely used external wall insulation materials are: external wall insulation mortar, polyphenylene rubber powder particle insulation mortar, polystyrene foam board, extruded polystyrene board, polyurethane insulation system and so on. Insulation materials, insulation mortar, polystyrene board, glass wool, rock wool, etc. can be used as insulation materials. With research and development, some self-insulating wall materials and new energy-saving products have emerged, such as shale modulus perforated bricks, silty bricks, and aerated concrete bricks. Walls built using these products have good energy efficiency. effect. For the completed houses, experts suggest that they can also process or modify the exterior windows, exterior walls, floors, doors, and ceilings. Or clever use and introduction of climbing (vine) plants in the balcony and other places to form baffle or horizontal shade, can reduce the temperature of the external surface of the external wall in summer by 4 to 5 degrees Celsius, indoor temperature and internal surface temperature of the external wall can also be reduced 1 degree Celsius or so. At present, the transformation of the facades of the island's buildings are actively using energy-saving materials to promote energy conservation concepts.

Favoring low consumption and superior products According to reports, many new products developed by new companies using new materials have made great contributions to building energy conservation. For example, a system energy-saving door and window produced by Qingdao Tenglong Aluminum Co., Ltd., the energy-saving doors and windows in the door and window structure design, the various parts of the doors and windows, such as aluminum profiles, hardware accessories, plastic strips, equipment, processing technology, technical support , Even fixing screws, etc. as a whole to consider, after careful design, with good tolerances, advanced processing, production process, with high quality performance, economical, beautiful and effective combination.
