Building energy saving: focusing on four categories of insulation materials and others
Building energy conservation has potential market in our country, which has become the key factors and lasting unshakeable national policy in the energy sustainable development in our country.
Building energy saving is expanded from three aspects, focusing on four kinds of products:
Building energy efficiency can improve the maintenance structure's thermal resistance value and the airtight ability mainly from exterior wall, roofing, door window, thus to achieve the purpose of saving energy consumption. The ministry of construction focus on developing energy-saving wall, roof, doors and windows suitable for various climate conditions, especially the external wall thermal insulation technology and energy efficient Windows and doors, develop all kinds of new high efficiency and energy saving wall material, thermal insulation materials and high performance architectural glass. Based on the key promotion, we think the following four categories of products has broad market demand: new wall materials, insulation materials, low-e glass and photoelectric glass.
Bayer Material Technology North American environmental construction program started
Bayer Material technology company today announced the official launch of the North American Free Trade Zone Environmental Commercial Building Project. The focus of the project is to promote collaboration among industry, academia and government to provide raw materials and all aspects of building solutions for building decision makers.
John Houston, senior vice president of coatings, adhesives and specialty chemicals department at Bayer Material Science and Technology company, said that environmental protection commercial building projects are in line with the company's long-term business goals. "Bayer has long been committed to the product innovation, management and sustainability, and our products have been used in many sustainable building designs, and the eco-friendly construction project perfectly embodies Bayer 's product concept and has contributed to our development in the field of sustainable construction.
Spray insulation coating the buildings will be whole energy saving in Shunde within 10 years.
Recently, Shunde district announced the long-term development project for building energy conservation, and proposed that the construction of new residential buildings and public buildings in the whole area will be 50% energy efficient by 2015. By the year 2020, most of the existing energy-intensive buildings will be transformed into energy conservation construction.
The project shows that most of the existing civil buildings built in early 1990 between the end of 2016 of Shunde district were energy-intensive, of which their overall energy consumption is electricity.
Since 2008, the civil building electricity consumption of Shunde district has exceeded ordinary industrial electricity consumption, the average annual growth rate of civil building power consumption during 2006 to 2008 is three times the total electricity consumption.
The goal of the program is to implement energy saving 50% of the new built buildings by 2015, and by 2010, the vast majority of the region's high energy consumption will be transformed into energy-efficient buildings.
In order to accomplish this goal, the programm proposed to spray the insulation coating on the outer surface of the building, adopt the internal insulation measures to improve the thermal performance of the wall, and green the surface by paving soiled or soilless green vegetation on the roof, preferred shading energy-saving glass, etc.
Construction materials that do not meet the "low-carbon" concept will be eliminated in Beijing
Recently, the Beijing Municipal Housing and Urban Construction Committee (hereinafter referred to as the Municipal Construction Committee) issued a message that according to the latest version of "Beijing to promote, limit, prohibit the use of building materials catalog" draft (hereinafter referred to as the draft), Beijing will ban or Limit the use of high energy consumption, poor safety, not meeting the "low carbon" concept building materials.
The draft includes a total of 38 prohibited products, 46 restricted products and 42 promotional products.The new version, which was first introduced or expanded at 28, more than doubled from the previous five to 12.6.
According to the draft, during production, high energy consumption, low safety performance building materials, such as the environmental polluted clay bricks, destruction of cultivated land and vegetation clay and asbestos shingle that may endanger human health, will be prohibited from use.
The draft also restricts the use of incandescent lamps with high energy consumption, low light efficiency, high temperature and poor safety, and prohibits its use in new public buildings and fine refurbishing dwellings. After the completion of rough housing to the decoration stage of low utilization rate, you can temporarily install cheap incandescent.
The draft will be jointly issued by the municipal commission of construction and municipal planning commission, based on consultation and feedback.
German experts say "sustainable building efficiency" is a global challenge
Mr Hesse, President of the Bavarian architects' association, argues that "sustainable building energy efficiency is a global challenge".
Mr. Hesse pointed out that at present, building energy consumption gradually increased, building materials gradually increased, while the sustainable construction is very few, so that human dependence on fossil energy is growing, which is not conducive to meet the needs of long-term use of energy , So it is necessary to build a sustainable building.
Hesse said, in order to meet the needs of future occupants, only through global cooperation to complete, the use of renewable materials, use of solar energy, the use of natural ventilation and thermal energy storage in summer that don't need technology.
Mr. Hesse pointed out that sustainable construction is not a single view of every building, sustainable building is as much as possible to reduce energy consumption, be in harmony with he whole society and nature while increasing the space, which makes it difficult for one or several countries to achieve this global harmony. In addition, both in Europe, America and China, sustainable building energy efficiency is of great significance, a single, fragmented region is not its proper meaning, only the sustainable energy-saving buildings into the globalization, can the goal of sustainable architecture be achieved.
