Eco-efficient buildings - the perfect fusion of art and technology

    Huge building energy consumption and increasing damage to the environment has drawn increasing public attention, building ecological energy also will become an important task.
    Government advocacy, policy development, media campaigns, for a time, some words appear frequently in our line of sight, booster cables such as: ecological building, energy efficient buildings, green building, high-tech construction, intelligent building and a series of words have changed get familiar with it. All of these terms to analyze the nature, can be summed up by two points: the high comfort and low power consumption. The current construction market, this real high-low-power products are extremely rare comfort, most products are in the use of various terms for speculation, only one or two high on a simple assembly, and then advertises itself as eco-efficient buildings,battery clip so the market is mixed, hard to distinguish. So, what is the real eco-efficient buildings? What can be done to create a high level of eco-efficient buildings?

    Eco-energy saving building not Zhaomaohuahu, simple replication.

    China has a vast,tow rope spanning several climatic zones, according to the different climate is divided into five climatic regions, each region has their own different climate. Climate on building comfort and energy consumption have a considerable impact, ratchet tie dowm so when making the design requirements of the local climate characteristics have a clear understanding of local conditions and to select the appropriate design strategies to maximize the potential benefits of the use of regional climate and to match the architecture and purpose of the local climate. On the other hand, a construction in which each area, orientation, function, style is different, therefore, the design should be from the topography, vegetation, water, sites, architectural nature, form, shape, orientation and other aspects consideration, and can not see the success of a building to Zhaomaohuahu, simply copy them to do so, probably in more capital investment, not only fail to achieve the purpose but have backfired.

    Into the system for the application of technology to prevent the generation of short-board effect.

    With the development of technology can be applied to new technologies, new materials, 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 the means, the aim is through the application of scientific and technological means to achieve the construction of high energy consumption as well as zero-energy comfort. Now how many real estate how to promote their use of high-tech products and technologies, the purpose just to find some selling point, in order to use the application to technology and real estate were crowned head, attracting attention, not to careful analysis of the technology used is appropriate, can really achieve the purpose of eco-energy saving, and ultimately, the unnecessary waste or to be passed on to the consumer body. Secondly, the use of high technology should be considered to go into the system, each individual should be co-ordination between technologies and form an organic whole, so as to achieve their goals. At present, many buildings use a lot of high-tech, and even developed a culture of comparisons, like the use of more and more energy-saving technology, but there is no in-depth analysis with the organic systems, due to the unreasonable use of one or two technologies resulted in "short-board effect" occurs, although there are higher investment, but not achieve the purpose of low power consumption with high comfort. Again, the technical system and the level of adoption is not much, but rather whether there is targeted, it can solve the problem, the limited financial and technical input to achieve maximum effect under the. Finally, you can not blindly pursue high-tech, in many cases, some low-skilled, or just clever use of conventional techniques 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 clever mix of organic and combined to form a complete set of effective eco-energy saving system, the effect of energy than the original design can be 30-50%.

    One-sided to consider the issue can not build a high-performance products.

    Eco-efficient buildings is an organic whole, therefore, the design must be comprehensive, full life cycle considerations. From all directions is to proceed with all aspects of construction-related, such as: building and planning, external structure, control and improvement of solar radiation, natural ventilation and lighting, renewable energy use, high comfort, low-power indoor climate control systems, noise control, water resources and efficient source of circulation benefits, power and lighting systems, intelligent control systems and so on. No detailed analysis of a full range of building eco-energy saving programs, often ignores certain important factors, cause greater waste of resources. Life cycle refers to not only give full consideration to building construction in addition to investment, but also to calculate the whole life cycle of building maintenance and running costs, to find the best balance to achieve the real purpose of energy saving. Investment in technology and equipment will be to calculate the payback period of investment payback period and carbon dioxide as the basis, not for speculation, blind investment.

    The traditional mode of operation is not suitable for development of new products.

    Eco-efficient buildings is a very complex construction products, and the present, most of the traditional architectural design in the design mode, the phase of the program is basically the only architects to participate, and follow-up design, the professional is often fragmented, only the some basic information on mutual cooperation and mentioned, and to the equipment bidding, construction, inspection and commissioning phases, designers and less involved, so the entire implementation process for the formation of a lot of out of stock, can not guarantee the quality of the final product. For the eco-energy saving building this technology is more complex, demanding of design and construction projects, this design approach is clearly could not do, because many technology system is in phase of the program should be considered, otherwise difficult to join in the subsequent design and requirements in the design of construction closely with the professional, so as to reflect the design intent to ensure that the final results.

    In response to this current situation, five with international experience from abroad, the concept of "integrated design" (IDP) of this concept, both in the design of the first phase of the program will have the professionals involved in eco-energy saving, considering the planning, building, structure, energy systems, HVAC and other factors, preliminary ecological energy saving programs, and integrated in the design of the follow-up architecture, landscape planning, structural, HVAC, plumbing, electrical and building control architecture, interior design and other various professional by the professional organic whole and, in close collaboration, on building its own characteristics and the regional natural resources and the environment in-depth analysis, according to the climate characteristics and product requirements, using a combination of high-tech and sophisticated products in order to form a complete set of feasible appropriate, the internal energy of organic linked to the ecological system. In the follow-up of the equipment bidding, construction, inspection, testing and other aspects related to the design staff will be actively involved in providing professional advice to ensure the correct implementation of the system. A five-TPT with international participation in the design of the building, for example, due to the complexity of technology, every professional will have nearly 50 co-ordination of professional institutions.

    Difficult and demanding high-tech means high-tech products and tools should be manufactured.

    Eco-energy saving building its technology systems are complex, and its quality requirements are high. Difficult to rely solely on the design of some conventional techniques and experience to complete the design of high-tech. Especially in China, some of the traditional calculation method, design, traditional experience itself is outdated, not only is the deal with its ordinary construction has exposed all kinds of problems, but also how to solve more complex ecological energy saving buildings. Therefore, when the use of eco-energy saving should be high-tech design tools and advanced operating procedures to ensure the accuracy of the final result, for example, over the conventional method, the dynamic compliance of the year to determine the system capacity and operating conditions, the use of advanced computer simulation software, CFD effect on the design of the full simulation and verification, to ensure that the complex problems of class predictability. Werkhart International is the first architecture firms in the CFD simulation using the advanced design of the software necessary for all simulations to ensure practical results.

    Clear indicators to give consumers confidence.

    Now he is a lot of properties for sale are the nominal energy efficient building, but when you ask it in the end how much energy each year, how much use it can save running costs each year, few people can provide a clear answer, because no one knows. And a true eco-energy saving design, it should be quantified, should be able to clear out the building's energy consumption, resource consumption and how much, how much carbon dioxide emissions, the number of amount of investment, payback period is. So this requires the designer to know what time the design and use the necessary means for computing and checking, to make the necessary data, so the 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, thus making energy-saving building construction, especially the eco-design, should take full account of their functions and features to the presence of form follows function, the construction techniques perfect combination of art and architecture, not the blind pursuit of visual impact, even sensational, creating some products do not meet the scientific laws, only increasing the energy consumption reduced comfort, but also caused a fatigued or no beauty at all. Five international design combined 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 meet the planning plot ratio, the gap between two buildings becomes very narrow, if the usual structure, the square will be very strong wind, pedestrians walking and safety, so the design to take into account to that calculated by simulation software, remove the lower corner of the building, using a special tension structure, increase in the cost of much of the premise, the effective elimination of the square formation of the wind, while achieving a modern architectural style, while meeting the government, owners and users of the requirements to achieve the architecture, structure, technology and the perfect combination of the ecological environment.

    High comfort than luxury, comfort and savings should be balanced.

    Currently, the state created to promote saving things harmonious society, and thus eco-energy saving building industry is so. Not the blind pursuit of high-luxury comfort, low energy consumption not only pay attention to energy savings, but in the guarantee adequate conditions of comfort, save energy and reduce consumption as much as possible, find a balance between the two to achieve the ultimate state the purpose of promoting eco-energy saving .

    Science and technology are means to an end, in order to create a high comfort level that zero-energy only into low-power system for the appropriate use of various high-tech to be in order to create a new generation of high-comfort low energy building products.
