The building exterior wall sealing strong

The building exterior wall sealing strong, using solar energy, geothermal energy for heating and cooling; Use building natural heat gain can reach a comfortable temperature at room temperature; Use of the roof space building photovoltaic power station & Warehouse Building; & hellip; These still can only stay in the good intentions in the energy-saving, environmental protection, comfortable low energy consumption building is now in Harbin city building has emerged. Starting this year, the green building, passive and low energy consumption and renewable energy building three new buildings start the pilot project will be completed in Harbin city putting-in-service proactively.

Green building energy saving, section land, water, and materials

According to the Harbin city is built appoint relevant controller introduces, building energy consumption accounted for 30% of the total energy consumption for the whole society to reduce building energy consumption is an important subject of construction industry. Our country "the green building evaluationstandardThree rating "will be the green building points, respectively is one, two, three star, three star as the highest level. To give green building rating refers to in the construction of whole life cycle, maximize resource conservation, energy conservation, section land, water, and materials), to protect the environment and reduce pollution, provide people with healthy, applicable and efficient use of space, about more than star number, the higher energy saving.

Harbin city started in 2010 pilot green building construction project construction field, last year, there have been three residential projects for national green buildingdesignLogo, total construction area of 181500 square meters. Among them, wanda plaza area F house national stardesignAssessment identifies, marina & middot; Senna villa MuYun C city homes and obtains the national two-star logo design evaluation, Calvin can stream tree garden residential 1-3, 6, 7 won the national three-star logo design evaluation, the first in the three northeast provinces. Harbin city is now actively organize the west railway station, we great shopping plaza and the west wanda hotels, the green building of project application, such as red, elementary school, west campus.

assive and low energy consumption building need not heating room temperature also

assive and low energy consumption building originated in Germany, is the world's most advanced energy saving buildings. Compared with ordinary buildings, passive and low energy consumption building almost no heat exchange with the outside world, insulation performance is better, save energy over 80%. It is mainly through high heat insulation sound insulation, sealing capability of building external wall and the use of solar energy, geothermal energy and other renewable energy for passive heating and cooling, finally realizes the low energy consumption. For Harbin this winter cold, summer heat, heating and cooling coal consumption power consumption big cities of the north, passive and low energy consumption building promotion construction not only saving the cost of living, and can meet the requirements of energy conservation and emissions reduction.

assive house has strict design standard, low energy consumption requires complete without heating or under the condition of using less energy, use of building natural heat gain to indoor temperature 20 ℃ to 26 ℃, that is to say, indoor can need not heating heating room temperature can also be to amount to mark; Relative humidity was 40% ~ 60% to ensure that the interior condensation is not moldy, surface without dewing phenomenon within the window. Such strict design standard, solve the cost of living, energy conservation and emissions reduction, and the contradiction between the living comfort.

Learned, Harbin in August 2011, start the passive low energy consumption building demonstration project construction, already with Calvin can & middot; Stream tree courtyard 3 house a total of 30000 square meters, total 3 project and following the red at primary school, a project is classified as passive construction demonstration project. Among them, can Chen & middot; Stream tree garden has a total area of 7700 square meters house 1 project construction, will be completed by the end of putting-in-service proactively; After elementary school, at 2.7 square meters demonstration project is currently in design.

Renewable energy building roof building photovoltaic power station

Renewable energy building applications is the use of solar energy, shallow can, industrial waste heat, biomass and other renewable energy to power supply, heating, air conditioning and buildings to provide living hot water, etc., to reduce building energy consumption with regularity.

In 2012, the city launched the solar photovoltaic building integrated engineering, mainly is the use of large-scale public building roof space advantage, building small rooftop photovoltaic power station. At present a total of four projects are implemented, including jiuzhou electric 2 mw photovoltaic building integrated project, we great shopping plaza 2 mw photovoltaic building integrated project, are classified as national solar photovoltaic building integrated demonstration projects, and obtains the national fiscal subsidies, project is the stage of Warehouse Building http://www.jingtabuilding.com/steel-structure-warehouse.html. We great shopping plaza, 1 mw daylighting roof photovoltaic building integrated project, the comprehensive passenger transport hub west plaza parking building 0.5 mw photovoltaic building integrated photovoltaic building integrated project is to complement to national declaration demonstration project.
