Received today from the China Green Building and Energy Committee on Communications, introduced from Singapore's international experience, is reproduced below:
Singapore is a scarcity of natural resources, with water and debris to have to rely on imports of the island, in the face of limited resources and sustainable development of the contradiction between the Government of Singapore to encourage through policy, legislative control, market-driven, education and other methods to promote energy saving, environmental protection, green building, and made remarkable achievements.
new initiatives
Singapore government awards
green building for energy conservation, sustainable development, awareness is very strong, from government and enterprises to the public, there is a real ecological environment and energy conservation, as the life of the green consciousness. in urban construction, the focus reflected in the attention to green building and persistent pursuit.
Singapore in January 2005 began the implementation of green building certification program logo. According to the Bureau of Singapore, the person in charge, identify the major assessment of green building construction and environmental impact performance, including energy, water, site and project management (or the management and operation of existing buildings), indoor environmental quality and environmental protection, five aspects of innovation. According to certified class is divided into high and low score (qualified), Gold, Gold + Award, Platinum Award four grades, including certification level for the minimum requirements. Green Building Construction Bureau to identify the application by the owner. Construction Bureau in accordance with the construction area charge a certification fee. to achieve Gold level or above, the Government in accordance with the building area per square NZ 3-6 to give the reward. To this end, the Government provided 20 million Singapore dollars a year as an incentive funding. owners can make green building design stage identifies the certification application, the Bureau of the design drawings can be made in accordance with its certification, to encourage and guide the owners in accordance with the requirements of green building design, construction and energy use management. Green Building logo certification review once every three years, where the unqualified will be rescinded.
green building certification program, Stages of identity 1 .2005 months, the implementation of the voluntary certification .2007 April, all building area of 5,000 square meters or more in new public buildings mandatory certification. since 2008, all construction area of 25,000 square meters of new buildings above the mandatory certification .2010 years ago, the existing public buildings, the construction area of 25,000 square meters or more, the mandatory certification.
Currently, Singapore total of 62 buildings identified by the green building certification. According to the Bureau of the plan of Singapore in the next 10 to 15 years To achieve the new construction and existing building energy consumption reduction of 25% target.
high-rise buildings since the transfer of new technologies, Hall, the total area of over 58,000 square feet. The building known as and location to minimize the heat load, full use of natural wind, and the use of the performance envelope of the insulation to prevent heat transfer. The outer edge of the glass canopy covering most used. the whole body building divided into two blocks, one of the body mass hanging above the ground, so wind can flow naturally, and thus play a role in cooling. the glass atrium above the top of the automatic shading devices, the use of hot air convection will be pulled out of the indoor, naturally formed air convection. The building uses daylighting strategy access to natural light as much as possible. indoor light and temperature changes can be carried out with a pleasant outdoor environment, the regulation is only part of the building with air conditioning inside, the rest are the use of natural ventilation or mechanical (such as fans) cooling. plenty of light and a series of installation of facilities in the dark, making the most of the interior space can use natural light, without the need to rely on excessive use of lighting. architects also use a partition inside the building temperature control system, customized for each individual region's temperature control scheme.
construction waste recycling more than half of Singapore's construction waste generated in 2006 about 60 million tons, produced about 1,600 tons daily, 98% of construction waste have been addressed, 50% - 60% of the construction waste recycling achieved. Singapore government-funded enterprise specialized construction waste, construction waste on the implementation of franchising, 4-5 at home by bidding to determine the construction waste disposal enterprises to develop business, and finance enterprises to develop construction waste recycling technology research.
Fuquan Environmental Pte Ltd HSBC funded by the Government of Singapore's largest companies specializing in construction waste, construction waste is the sole owner of Singapore, re-use of technology companies. huge breakers hit the recycling of construction waste into small particles, and then transferred to the cement mixing tank tracks ... ... After br> At present, the Singapore manufacturing concrete ditches, 30% used recycled concrete. recycled concrete is also used for the construction of car parks or for paving stone trim.
grasp of construction waste in addition to creating recycling of construction waste in Singapore is also actively promote the source reduction strategy, focusing on reduction of construction waste from the source. through the establishment of waste disposal fee system, increasing the cost of construction waste emissions, encourage the contractor to strengthen management of construction waste, reduce construction waste emissions, the full cycle use.
energy efficiency of new mechanisms and specialized support
order to solve the energy-saving investments in the traditional manner, energy-saving projects by investors to bear all the risks, which restricts the use of energy investor enthusiasm for new technology problems, Singapore actively promote energy-saving mechanism based on market regulation - energy contract management.
the so-called energy contracts management, is the energy services company to contract energy management mechanism for customers to implement energy conservation projects, to provide energy-saving potential and energy conservation projects feasibility analysis, project design, project financing, equipment purchase, construction and installation, saving energy detection, personnel training and other projects the whole process of service contracts to customers that promised to achieve energy savings and energy efficiency.
Singapore National Environment Agency in April 2005 introduced to equipment management system, which the Singapore Ministry of the Interior, Foreign Affairs, Ministry of Environment, the Police Headquarters building and other government agencies to reduce energy consumption per year 30%, while the Singapore Post Centre, after the energy saving to reduce energy consumption by nearly 50%, as the implementation of energy efficiency assistance programs to enhance the typical sample.
Post Centre commissioned Trane energy-saving air-conditioning company, through the re-installation of three water chillers, to enhance part of the pump system, establish a meteorological detectors, and with complete real-time monitoring system, to consumption rate to O.6W/RT (kW / tons of cold), than the local general building chiller required 1-l.2W/RT (green building certification requirements identified to O.9W/RT), to improve the efficiency of almost doubled. postal center for the project invested about 200 million Singapore dollars, according to utility bills, is expected to recover the investment in one year and eight months, an annual saving of 120 million Singapore dollars, the investment rate of return of 60%.
Singapore National Environment Agency and the Sustainable Development of National University of Singapore also co-launched by the building energy consumption labeling scheme: those who can achieve the energy efficiency performance of 25% and can provide a healthy indoor environment, you can apply for access to the label. It is designed to Singapore building energy-saving measures to improve the degree of attention, motivate owners, contractors and effective use of energy.
for the development of green building, the Singapore Government adopted a flexible variety of government incentives and incentives, in addition to grant funds, it also includes tax , land and other incentives. For example, since 1996, began to implement energy-saving equipment required accelerated depreciation; energy efficient equipment investment allowance; for use in construction waste disposal factory, the Government for the treatment of low land rent and so on. Singapore government recently announced In 5 years will invest 50 million Singapore dollars to set up research funds, promoting green building energy saving technology research.
