Building energy saving measures in foreign developed countries is worth learning from

The construction of energy-saving work is a complex project, to consider saving energy from the life cycle, building energy conservation as an important part of the whole society of energy saving and emission reduction in the process of development, we can draw lessons from some foreign countries take a series of measures of reference.

Germany

Through the government agencies, professionals and experts on the construction and construction of the construction of strict monitoring, to ensure that all building energy consumption in line with the existing laws and regulations and requirements. The German government also took out 3 billion euros to subsidize the transformation of the old building energy-saving. At the same time for the construction of energy-saving projects to provide low interest loans, and lower energy consumption, the lower the interest rate on loans.

German building insulation energy-saving technology requirements specification, new buildings must be issued by the heating needs of energy and building energy consumption core value, construction must be issued by the building heat loss value, especially the external heat loss of building structure, that the energy required for building every year, and a breakdown of electricity needed, fuel, gas, coal, building energy consumption is made calculation table for reference.

Consumers in the purchase or lease of housing, construction developers must issue a certificate of energy consumption, to inform consumers of the residential energy consumption per year, including heating, ventilation and hot water supply.

The research and application of building energy-saving technology in Germany, not only for economic interests to consider, but also to radically reduce carbon dioxide emissions, reduce the greenhouse effect in the world, has a strong practical operational.

Japan

First, through the relevant agencies, such as the construction of the environment to save energy institutions, the Association for the promotion of environmental symbiotic residential, Industrial Environmental Management Association, identification, evaluation, popularization and recognition of residential energy conservation and environmental protection enterprises. The Japanese government focused on leveraging the various non-governmental organizations (NGO), a non-profit group (NPO), making all kinds of identification and authentication system, and gradually eliminate pollution and high energy consumption products, improve and promote enterprise products, energy conservation and environmental protection. For example, high visibility, founded in 1974. Building energy efficiency in Japan has experienced a process from spontaneous to mature.

Two, is the state legislature and the government through laws and regulations and other forms of active intervention, the promotion of residential energy conservation and environmental protection design and application.

The Japanese government focused on leveraging the various non-governmental organizations (NGO), a non-profit group (NPO), making all kinds of identification and authentication system, and gradually eliminate pollution and high energy consumption products, improve and promote enterprise products, energy conservation and environmental protection. For example, high visibility, founded in 1974, the fine residential Bupin system.

In addition the goods carried out in accordance with law (indeed began in 2000 to ensure that the promotion of quality residential residential properties method) produced by said system, thermal environment and energy saving of residential projects set the benchmark, through a special inspection organ for evaluation evaluation of residential, will receive an evaluation book, if later because of residential quality the problems and disputes, only need to pay 10 thousand yen to obtain the corresponding organs with the help of.

In addition, according to the "Japanese economic news" reported that the Japanese Ministry of environment will set up a special subsidy reform in 2013, for energy saving reconstruction subsidies office buildings and other buildings, each building for a carbon dioxide emissions reduction target of 20%.

In addition, for the effective use of forest resources, increase the absorption of carbon dioxide, the environment, will also set up purchasing wood integral system, consumers through the purchase of Japanese wood can obtain the corresponding points, the points accumulated to a certain amount of convertible energy-saving concept product.

For the smooth implementation of the above two systems, the government plans to arrange a budget of about 100-200 billion in 2013 budget.

The Fukushima nuclear power plant accident in 2012 after Japan's nuclear power is seriously affected, some coal-fired power stations have to operate to compensate for the power supply gap, in order to effectively control greenhouse gas emissions, the Japanese government plans to cut emissions from the whole society and increase the forest to take measures in two aspects of oxygen absorption.

In the transformation of energy-saving building, gold government will retrofit of air conditioning and lighting system of the office building renovation costs 1/3 of all subsidies, in addition to financial institutions will also provide preferential financing policies; in increasing forest oxygen consumption, the government will encourage people to buy domestic wood products, so that more funds can stay Japan continues to be used for forest protection, afforestation, increase vegetation coverage, and the integral obtained by purchasing the domestic wood can be used for the exchange of LED bulb, recycled paper products such as notebook energy-saving concept.

The Japanese government is the goal of greenhouse gas emissions from 2008 in 2012 to 6% in 1990, less than the forests absorb the contribution of 3.8%, family enterprises, voluntary reduction contribution of 0.6%, while emissions from overseas purchases accounted for the remaining 1.6%.

U.S.A

In the United States, California, New York and other economically developed areas, building energy efficiency standards are stricter than the federal government standards. For example, as a government agency of California's main energy conservation management, the California Energy Commission (CEC) to develop and implement the most stringent standards of energy-saving buildings in the United States and home appliances and labeling system, the standard every few years (generally 3 years to 5 years) is updated, to fully consider the development of new technology the. The United States government also encourages voluntary section.

In the United States, the construction of energy related to the cost of ordinary families, so it is a market-oriented indicators, building energy efficiency market depends on energy prices, household income and living standards and other factors.

Its role is not significant, the main means is the development of industry and product standards, develop and recommend new energy technology etc..

The United States government also advocates a voluntary energy saving logo.

The most typical is the United States Environmental Protection Agency (EPA) and the United States Department of energy (DOE) jointly promote energy star project, access to Energy Star logo products generally exceed the corresponding minimum energy efficiency standards for such products.

The logo has been in operation since 1998, with the main target of commercial buildings.

Energy efficiency is far ahead of similar buildings.

In order to build a residential building as an example, the U.S. Department of energy from the wall heat insulation layer, glass doors and windows, roof and underground heat insulation, ventilation and air conditioning pipeline air tightness and insulation, water heater and hot water pipe insulation efficiency of every detail, a detailed explanation of how to do to meet the energy saving, and recommended energy star standards of building materials, the details have done very well.

As part of President Obama of the United States economy sustainable development blueprint, in early March of this year, the U.S. Department of energy (DOE) announced in 2012 during the fiscal year will have a $52 billion budget to promote the development and application of building energy efficiency technology, including advanced heating and air conditioning system, efficient insulation materials and doors and windows and roofs.

The budget will be used to innovate the development of building technology, demonstration projects and production, in order to accelerate the process of marketization, so that such products can be effective for U.S. households and businesses to reduce energy expenditure.

Summary

The fourth stage is to reduce greenhouse gas emissions (MitigationofCO2Emission), a higher level of energy saving concept. In our country, from the beginning of 80s began to pay attention to building energy efficiency, compared with the foreign countries started late, the construction of energy-efficient technology level and there is a certain gap between the foreign countries, so some foreign good model is worth learning and reference. Our country can achieve the fourth phase of the true sense of energy conservation, it is still a long way to go.

In the recent decades, the content and meaning of building energy conservation has been developing in the world.

In developed countries, building energy saving can be said to be experienced four stages: the first stage is to save energy (energysaving), is required in the construction to pay attention to saving energy; the second stage is the conservation of energy (energyconservation), which is under construction, minimize the energy loss: the third stage is to improve energy efficiency (energyefficiency that is in the building), give full play to the utilization of energy, energy saving is a positive sense.

The fourth stage is to reduce greenhouse gas emissions (MitigationofCO2Emission), a higher level of energy saving concept.

In our country, from the beginning of 80s began to pay attention to building energy efficiency, compared with the foreign countries started late, the construction of energy-efficient technology level and there is a certain gap between the foreign countries, so some foreign good model is worth learning and reference.
