Increasingly large building energy consumption and environmental damage caused by growing public concern about eco-energy saving building also will become an important task. Government advocacy, policy development, media publicity, a time, some words frequently appear in our sight, such as: ecological building, energy-efficient buildings, green building, glue stick high-tech construction, intelligent building and a series of words are changed get familiar with them.
All of these terms, of its nature, can be summed up with two points: the high comfort and low energy consumption. The current construction market, the high comfort of this truly low-power products are extremely rare, most products are in use of the term for speculation, glue gun only to the 12 high-tech simple assembly, and then advertised that they are eco-energy saving building the market is quite a mixed bag, makes difficult to distinguish. So what are the real eco-energy saving building? What can be done to create a high level of eco-energy buildings?
Eco-energy saving building not Zhaomaohuahu, simply copy the.
China has a vast, spanning several climatic zones, according to the different climatic characteristics were divided into five climatic regions, each region has their different climatic characteristics. Climate on building comfort and energy consumption have a considerable impact, therefore the design of the requirement when the local climate characteristics have a clear understanding of local conditions and select the appropriate design strategies to maximize the potential advantages of using the regional climate and building and local climate to match the purpose. On the other hand, a construction in which each area, orientation, function, style is different, so the design should be from the topography, vegetation, water resources, site, building character, form, shape, direction and other aspects consideration, but can not see a building successful, Zhaomaohuahu its simple reproduction, this is likely to put in more funds, not only not achieve the intended purpose but are counter-productive.
Into the system for the application of technology to avoid the generation effect of the short board.
With the development of technology can be applied to new technologies, new materials are more and more the face of such a diversity of techniques, how to select and match to become an important issue. First, the use of high technology is not an end but a means to the application by means of science and technology to achieve high comfort, low energy consumption buildings and even the zero-energy. Now how many real estate information how to use their own high-tech products and technologies, the purpose just to find some selling point, in order to use the application to branded technology and real estate were first attracted attention, not to carefully analyze the techniques used if appropriate, can really achieve the purpose of eco-energy saving, the end, the senseless waste is to be passed on to consumers. Second, the use of high technology into a systematic way should be considered, all of the match between technologies should form an organic whole, so as to achieve the purpose. At present, many buildings use a lot of high-tech, and even formed a kind of comparisons of the atmosphere, like the use of more and more energy-saving technology, but there is no in-depth analysis of organic systems with, as a result of unreasonable use of two technologies resulted in "short-board effect" occurs, although a higher input, but not achieve the purpose of high comfort, low energy consumption. Again, the number of technical systems and the level of use is not, but rather whether there is relevant, whether it can solve the problem, the limited financial and technical input to achieve maximum effect under the. Finally, the pursuit of high technology can not blindly, in many cases, some low-skilled or clever use of conventional technology is precisely to achieve the best results. A very typical example is the five co-design of the International Theatre of Hefei of ecological energy systems, the Grand Theatre in a limited capital investment, only two or three high technology used in other conventional systems are ingenious mix of organic and combination to form a complete set of effective eco-energy saving system, the effect of the original design than the 30-50% energy saving.
One-sided consideration of the problem can not create high-performance products.
Eco-energy saving building is an organic whole, therefore, the design must be comprehensive, full life-cycle considerations. Is from the full range of aspects related with the start of construction such as: building and planning, external structure, control and improvement of solar radiation, natural ventilation and lighting, renewable energy use, high comfort, low energy consumption of indoor climate control systems, noise control, water resources, recycling of efficient and source, power supply and lighting systems, intelligent control systems and so on. No detailed analysis of all-round construction of ecological energy saving program, some important factors often overlooked, cause greater waste of resources. Life cycle refers not only to give full consideration to building construction in addition to investment, but also calculate the whole building life cycle maintenance and operating costs, in order to find the best balance to the true energy-saving and environmental protection. Investment in technology and equipment necessary to calculate a certain payback period and carbon dioxide recovery period, and can not for speculation, blind investment.
The traditional mode of operation is not suitable for development of new products.
Eco-energy saving building is a very complex building products, and the present, most of China's traditional architectural design in the design mode, the program phase is basically the only architects, but the follow-up of the design, the professional is often fragmented, only to Some basic information on mutual cooperation and mentioned, but to the equipment bidding, construction, commissioning and commissioning phases, the designer has less involved, so the entire implementation process to form a much interrupted, can not guarantee the quality of the final product. For the ecology building that is much more complex and demanding design and construction projects, this design approach is clearly could not do, because many technology system is the stage in the program should be considered, otherwise difficult to join in the follow-up design, and in the design and construction professionals when asked to closely, so as to reflect the design intent, ensuring the final result.
In response to this current situation, five joint international learn from foreign experience, the concept of "integrated design" (IDP) of this concept, both in the design phase of the initial program for professionals involved in ecological energy saving there, considering the planning, building, structure, energy systems, HVAC and other factors, preliminary ecological energy saving programs and the design of the integrated follow-up architecture, landscape planning, structural, HVAC, plumbing, electrical and building control architecture, interior design and other professions by the professional organic whole and, in close collaboration, on building their own characteristics and regional natural resources, environmental in-depth analysis, according to the climate characteristics and product requirements, and the combined use of sophisticated high-tech products, to form a complete set of feasible appropriate, the internal organic eco-energy saving system connected. In the follow-up of the equipment bidding, construction, inspection, testing and other aspects related to the design staff will actively participate in and provide professional advice to ensure the correct implementation of the system. International participation in order to design the five co-TPT building, for example, as to the technical complexity of the professional coordination of each will have nearly 50 professional institutions.
Difficult and demanding high-tech products should be high-tech means and tool manufacturing.
Eco-energy saving building their technical systems are complex and their quality requirements are high. Difficult to rely solely on the design of some conventional technical means and experience to complete the high-tech design. Especially that in China, some traditional in the calculation method, design concepts, 传统 experience itself, already out of date, both Pian Shi Yong its Yingduiputong building also has exposed the kinds of problems, Huan 如何 can solve more complex ecological Jieneng building. Therefore, eco-energy saving during the design should use high-tech tools and advanced procedures to ensure the accuracy of the final results, for example, the conventional method in the above analysis of the dynamic annual meet to determine system capacity and operating conditions, the use of advanced CFD computer simulation software to design the full effect of the simulation and verification, to ensure that the complex issues of class predictability. V. International cooperation is the first architecture firms nationwide use of advanced CFD simulation software in the world all the necessary simulation designed to ensure practical results.
Be clear to the consumer confidence index.
Now many properties for sale are the nominal energy-saving buildings themselves, but when you asked it in the end how much energy each year, how many use it to save running costs each year, few people can provide a clear answer, because no one knows. And a true eco-energy saving design, should be quantifiable, should be able to clear out the whole building energy consumption, resource consumption and how much, how much carbon dioxide emissions, the number of investment amount, recovery period is. This requires the design, therefore, when designers should be aware of and adopt the necessary means to carry out calculations and checking, the necessary data, so that owners can provide adequate basis for decision making and in the future after construction of the acceptance criteria.
Architecture and building technology integration.
Architectural design is a technology with an artistic component engineering, technical project is its primary nature, therefore making buildings energy efficient building design, particularly the ecology, we should take full account of its function and characteristics in order to determine the form of function exists, building technology with the perfect combination of architecture, rather than blindly pursue visual impact, even sensational, creating products that do not meet scientific law, not only increasing the energy consumption reduced comfort, and creating a Shenmeipilao or no beauty at all. V. International co-designed Bluetooth Crystal Plaza in Shenzhen by the very visual impact of the structure, but the reason for using this form is not for visual impact, but for eco-design considerations. The land subject to planning conditions, to achieve the Party satisfaction and planning plot ratio, the gap between two buildings becomes very narrow, if the usual structure, the future will be very strong wind Square, pedestrians walking and security, so designed to take into account to that calculated by simulation software, remove the lower corner of the building, using a special form of tensile structures, without increasing much more in cost, the effective elimination of the square formation of the wind, At the same time achieve a modern architectural style, while meeting the government, owners and user requirements, achieving the architecture, structure and ecological environment, science and technology the perfect combination.
High comfort is not luxury, comfort and savings should be balanced.
Currently, the state advocates to do to build an economical and harmonious society is so so eco-energy construction. Comfort is not the blind pursuit of high luxury, low-power not only pay attention to energy conservation, but in the guarantee adequate conditions of comfort save energy as much as possible, to strike a balance between the two and realize the ultimate goal of promoting ecological energy saving .
Science and technology are means to an end, in order to create high-comfort, low energy consumption resulting in zero-energy only into the system for the appropriate use of various high-tech to be able to create a new generation of high comfort, low energy consumption of building products.
