Description

Building energy conservation automatic checking method based on BIM
Technical field
The invention belongs to energy-saving building technology field, it is related to a kind of building energy conservation automatic checking method based on BIM.
Background technology
In terms of building energy consumption, the building energy consumption of developed country typically constitutes from 33% or so of national total energy consumption in the world, and China mutually maintains an equal level also in developing stage, but building energy consumption with developed country, and China building energy consumption still year by year Rise, with the quickening and the improvement of people's living standard of urbanization process, China's architectural energy consumption ratio finally will also rise to 35% or so.So big proportion, architectural energy consumption has become the obstacle of the economic development that govern China.
However, after seventies energy crisis, developed country starts to be devoted to research and carries out energy-saving building technology, China But the problem of this respect is have ignored, the energy-saving building technology level far behind developed country of China is caused.For example, domestic exhausted The hot merit of most of heating districts building enclosures can be all more close than weather developed country it is poor many.The heat transfer coefficient of exterior wall is it 3.5 to 4.5 times, exterior window is 2 to 3 times, and roofing is 3 to 6 times, and the air penetration of door and window is 3 to 6 times.
In recent years, energy-saving design in construction is accelerated in national requirements, has put into effect in succession and has been examined on energy-saving design in construction and construction drawing The Main Specification and standard of aspect are looked into, specification is made that regulation to the Shape Coefficient and heat transfer coefficient of building suitable multiple location, For example, the Shape Coefficient of regulations of rules severe cold and cold district public building should meet:Single construction area A (m2), 300<A≤ 800, shape coefficient of building≤0.50;A>800, shape coefficient of building≤0.40.Severe cold area Class A public building is each single vertical Face window-wall ratio (including printing opacity curtain wall) is not preferably greater than 0.60;Other regional each single facade window-wall ratio (bags of Class A public building Include printing opacity curtain wall) 0.70 is not preferably greater than.For exterior wall, the window-wall ratio coefficient of the exterior window exterior wall of different azimuth is also different, thing Face coefficient is 0.253, in the south 0.33, north 0.29.And in traditional CAD design pattern, due to the office of two dimensional surface design It is sex-limited, the data message of correlation cannot be carried in single CAD diagram paper, designer's building energy conservation during design drawing sets There is mistake in meter, it may appear that building energy conservation calculated description, report table, general description of construction and construction measure, the Various types of data on material list to a higher authorities for approval The phenomenon such as inconsistent, in terms of construction plan review, construction plan review designs lattice not tight to check on, examines not carefully, manual review work Work amount is big etc..A kind of building energy conservation automatic checking method rapidly and efficiently has become the active demand in process of architecture design, Also contribute to liberate the productive forces simultaneously, improve operating efficiency and design level.
The three-dimensional building design being currently based under BIM technology platform has been achieved for sizable development, BIM (Building Information Modeling) be using open professional standard, physics and functional characteristic to facility and Its related project life cycle information is digitized the performance of form, so as to for project decision provides support, be conducive to more Item purpose value is realized well.BIM is the information based data of the related data in integration engineering project based on threedimensional model Model, is the digital expression to engineering project entity and functional characteristic, can be by the data of projects stage different phase Information resources are attached, convenient to provide support to each participant of project.
