Guangzhou to use , low-rise building priorities

For the use of renewable energy, energy-saving regulations require that Guangzhou will be encouraged to promote the application of the civil , solar photovoltaic power generation, natural lighting and other lighting and heat pumps use renewable energy technology, full use of solar, wind, biomass energy, geothermal energy.

    Starting next month, real estate development company in Guangzhou, seller, not only to the publicity of the sale of housing energy consumption indicator, energy-saving measures and protection requirements, insulation works warranty and other information, the content should be written in house sales contract conventions. General Office of Guangzhou Municipal Government recently issued a notice, \"Guangzhou Energy conservation pilot scheme\" (hereinafter referred to as \"energy-saving measures\") from March 1 implementation date, energy-saving measures for new construction energy-saving measures, energy-saving and old buildings renewable energy use and so a detailed regulations.

Government buildings energy consumption limits set

It is reported that the implementation of energy-saving measures, including the scope of management of residential buildings in Guangzhou city, state organ office buildings and business, services, education, health and other public buildings. According to energy-saving measures, the Guangzhou municipal government will gradually establish civil year demonstration project to promote energy-saving system. Where the energy is better than national standards and local regulations, may declare the municipal civil energy demonstration project. Upon declaration of approval, will enjoy preferential policies and financial subsidies granted Guangzhou building energy demonstration project title.

Guangzhou Municipal Government will accept the business through personal donations, funding, etc., set up special funds for the development of building energy efficiency, Incentives, support system, focusing on building energy efficiency demonstration projects funded construction, construction materials, new technologies and energy efficiency research and development and industrialization .

For government buildings and large public buildings, energy-saving measures specifically requested electricity, water, gas and other departments to implement the energy consumption of these buildings regularly submit; government agencies to develop office buildings and large public buildings unit energy consumption limits; and the establishment of the corresponding energy audit, energy efficiency, a system of notification.

Central cooling buildings will be billing customers

Summer and warm winter in Guangzhou City, central cooling buildings and more, the characteristics of high energy consumption, energy-saving measures also provides Guangzhou gradually implemented the use of cold charging system. The end of a centralized cooling independent of civil users should install sub-metering device and the indoor temperature control device to achieve household billing. Building public corridors, staircase and other parts should be installed to use energy-saving lamps. Residential energy efficiency in public parts of the self-extinguishing switch should be set.

In the old buildings for energy saving, the energy approach requires municipal and district (county-level cities) construction administrative departments of large public buildings within the area survey and analysis and evaluation of the organization to develop transformation objectives and requirements, reported to the government for approval and implementation. Encourage the implementation of green building and other parts of the roof to reduce building energy consumption, encourage the transformation of flat roof sloping roof.

Priority to low-rise buildings use solar water heaters

For the use of renewable energy, energy-saving regulations require that Guangzhou will be encouraged to promote the application of the civil solar water heating, solar photovoltaic power generation, natural lighting and other lighting and heat pumps use renewable energy technology, full use of solar, wind, biomass energy, geothermal energy.

Approach also requires, Guangzhou City, the new 12-storey residential buildings and centralized hot water supply hospitals, schools, hotels, swimming pools, public baths and other public buildings should be given priority and building integrated technical design, and in accordance with the relevant requirements and technical standard solar hot water system. District, village, green square, the scenic area of ??the garden lights, lawn should be given priority use of solar energy, LED (light emitting diodes) and other energy saving lamps. Government should give priority to investment projects using solar photovoltaic technology.
 

New wall-mounted solar water heater warming the city

Industry experts said the wall-mounted water heater can solve the high-floor roof line is too long and the problem of limited installation space for the realization of solar integrated building and find a breakthrough, especially for urban high-rise building users, is a regular \"boring sun-type \"a revolutionary breakthrough in . Industry experts believe that to promote the integration of solar energy and buildings, solar energy is the future trend of development and the biggest bright spot, and there may be a watershed in China\\ s solar water heater industry.

    Solar water heaters in terms of energy saving, cost saving point of view is that today the government to develop renewable energy in the context, have to time to promote. The reasonable use of solar energy, to further promote the utilization of solar energy, has become the focus of the industry. Although solar water heater has a clean, energy-saving advantages, but a long time, in cities has not been widely used to form the trend. With improvement in technology and technology breakthroughs, solar water heaters gradually began building a place in the city.

It is understood that over the years, the city to promote solar water heaters is not satisfactory. Traditional solar water heater installation inconsistent with the city\\ s architectural style, the city and look into the solar industry the outstanding problems. Some residential properties for uniform planning requirements of the district, does not allow owners to install solar water heaters. In addition, the city most of the main multi-storey and high-rise residential, small roof space does not meet all the needs of households using solar energy installation, the roof on the various types and brands of water heaters placed clutter caused by the visual pollution. These are the traditional solar water heaters in the city to promote the bottleneck. However, this situation is expected to be a new solar water heater out of the window wall to break.

New out of the window wall and the water tank solar water heater collectors are separated from each other, the collector can be flexibly installed on the roof terrace walls or bottom of the window wall, excellent wind resistance; water tank is placed on the balcony on the ground or indoor wall. As the up and down the water in the room, water heater and then afraid of the winter cold, with wind, frost, high thermal efficiency advantages, greatly reducing the building restrictions on the use of solar water heaters, solar water heater can make the same as home air conditioning in accordance with the indoor unit and outdoor unit two parts of the free installation. Industry experts said that such a water heater can solve the high-floor roof line is too long and the problem of limited installation space for the realization of solar integrated building and find a breakthrough, especially for urban high-rise building users, is a regular \"boring sun-type \"a revolutionary breakthrough in solar water heaters. Industry experts believe that to promote the integration of solar energy and buildings, solar energy is the future trend of development and the biggest bright spot, and there may be a watershed in China\\ s solar water heater industry.

Mandatory installation of a significant effect

In recent years, some of China\\ s provinces, municipalities and local governments (such as Hainan, Jiangsu Province, Shenzhen City, Jinan City, Xingtai City, Sanmenxia City, etc.) have been promulgated and implemented with the mandatory installation of content to further promote the use of solar water heater policy Most require 12 layers (or 9 layers) must be installed on the following civil s, including the scope of residential buildings and public buildings.

Many solar water heater business, offered support and actively participate in and actively promote the \"put a installation policy\" implementation. However, in actual operation, some shortcomings have been exposed, which is the industry\\ s largest local protection ills. Experts believe that: in the implementation of the mandatory installation of solar water heater policy, supporting the introduction of a number of implementation rules and management practices, can prevent or curb the tendency of local protection. For example: It is recommended to further strengthen the solar water heater product quality supervision and management, in particular SMEs, to increase the proportion of supervision and checking of the product; proposed mandatory installation requirements give priority to certified products, and as soon as possible to carry out civil construction of product certification; recommended the gradual implementation of the national authorities of solar hot water system installation qualification system, strengthen the solar water heater sales, installation and after-sales service activities, supervision and management; suggest the importance of mandatory installation of active promotion and practice, etc., will help promote the use of high-quality products, China\\ s solar water heater market is conducive to survival of the fittest.

In fact, the problem with the survival of the fittest, as in the implementation of the policy of mandatory installation of solar water heater at the same time, supporting the introduction of a number of implementation rules and management practices, is to avoid unfair competition. For installation of solar water heaters into the residential situation, obviously can not just rely on price as the sole criterion for cell entry, but should be considered the quality of their products, installation techniques, operation mode, service, prices and other factors, to formulate a scientific project bidding and reasonable way, both for solar water heaters fair competition among enterprises, but also help to ensure that solar hot water systems in civil engineering quality.

Industry still needs policy support

China\\ s \"Renewable Energy Law\" enacted for the development of solar water heaters create the environment, but not enough to promote healthy and stable development of industry. China\\ s annual gross floor area to 1.5 to 2 billion square meters of growth, according to the national planning: to maintain the total amount of solar energy by 2020 will reach 300 million square meters, if the policy support in place to achieve 350 million square meters of total holdings, when the solar water heater can increase annual production to 108 million square meters (solar water heater with 10 years life cycle basis).

Whether it is the annual production of solar water heaters, or ownership, China already ranks first in the world, the world\\ s production and application of solar water heater power. Industry insiders believe that: At present, there are still many urban communities do not consider the requirements of buyers use the water heater to block the installation of solar water heaters. Government should as soon as possible, \"Renewable Energy Law\" rules, remove barriers to residential solar equipment. Prohibits local governments, developers, property owners to block installation; require construction design department set aside for new buildings should be made compulsory installation of solar water heaters, piping, installation of the circuit and the load-bearing platform; for such offices, schools, hospitals, hotels and other places, must be standard installation of solar products, especially the government departments should take the lead to do demonstration.
