Gather·Change丨"Self-cultivation" of Green Building

Promoting energy conservation and emission reduction in the building sector and promoting the comprehensive development of green buildings are of great significance to realizing the goal of double carbon. Exploring the development model of green building and accelerating the development of low-carbon and energy-saving building industry has long become the consensus of local governments, industries and enterprises.

Green building's Past and present Life

Green building refers to a high-quality building that saves resources, protects the environment, reduces pollution, provides healthy, applicable and efficient space for people to use, and maximizes the harmonious coexistence between man and nature in the whole life cycle.

In the 1960s, the Italian architect Paolo Soleri first proposed the famous concept of ecological architecture, which is the origin of green architecture.

In the 1970s, the oil energy crisis made people realize that the construction industry must take the sustainable development road, and building technologies such as solar energy, geothermal energy, wind energy and energy-saving envelope came into being.

In 1992, the United Nations Conference on Environment and Development explicitly put forward the concept of green building for the first time, and more and more countries began to study, practice and promote green buildings.

In the 1990s, the concept of green building was introduced into China and has been widely spread, and government departments have successively promulgated a series of Outlines, guidelines and regulations to vigorously promote the development of green building in China.

Talk about the development of green building in our country

In 2006, the promulgation and implementation of the Green Building Evaluation Standards marked a new journey for the development of green buildings in China.

In 2007, the Ministry of Housing and Urban-Rural Development issued the Green Building Evaluation Technical Rules (Trial) and the Green Building evaluation labeling Management Measures to gradually improve the green building evaluation system suitable for China's national conditions.

In 2010, the Ministry of Housing and Urban-Rural Development issued the Guidelines for the Evaluation of Green Industrial Buildings to start the evaluation system for green industrial buildings.

Subsequently, in the 13th Five-Year Plan and 14th Five-Year Plan, it is clearly proposed to comprehensively promote the development of green buildings and improve the level of building energy conservation.

With the support of a number of national and local policies, China's green buildings have witnessed a blowout growth. By the end of 2018, the total green building area in China had exceeded 3 billion square meters, and more than 13,000 projects had received green building evaluation marks. Green buildings have fully blossomed in the field of construction, creating a number of demonstration projects and benchmarking projects.

As the two major subdivisions of green building, the development momentum of prefabricated building and photovoltaic building integration cannot be underestimated. Prefabricated buildings can be prefabricated in factories and installed on site, so that the design is standardized, the production is factory, the construction is assembled, and the environment is friendly, the waste of resources is reduced, and the construction cost is reduced, which has become the mainstream trend of green building development.

Analyze the international green building evaluation system

At present, there are more influential green building evaluation systems in the world such as BREEAM in the United Kingdom, LEED in the United States, DGNB in Germany, CASBEE in Japan and so on.

(1) British BREEM green building evaluation system

BREEAM is one of the world's first and widely used green building assessment methods. There are more than 1 million buildings registered for BREEAM certification in more than 50 countries around the world, of which more than 250,000 buildings have been certified. In addition to quantitative and objective index evaluation of building monomeric units, BREEAM also considers the ecology of building sites and pays full attention to the influences of buildings on society, economy, natural environment and other aspects.

(2) American LEED green building evaluation system

LEED was established and implemented by the United States Green Building Council (USGBC) in 1995 and is currently one of the most influential assessment standards in the world. LEED attaches great importance to voluntary, advocating that owners, construction units, design units consciously promote sustainable development. Currently, with the release of LEED V4 in 2013, China has become the second largest LEED certification market in the world.

Mars Pet Food Tianjin factory project, plant won LEED silver certification, office achieved LEED Gold certification, wiskind technical team.

(3) Japan CASBEE green building evaluation system

CASBEE by the Japanese industry, academia and government departments cooperation, launched in 2005 to assess the building and the surrounding environmental performance of green building standards, based on the principle of voluntary evaluation, CASBEE is widely used in construction companies, design institutes, real estate developers and other fields, has been updated to the 2010 version of Casbee.

(4) German DGNB green building evaluation system

In 2008, Germany launched the world's second generation of green building assessment standards for the first time - the German Sustainable Building Certification Standard DGNB, and has been continuously updated and improved since. The DGNB system has been applied in many countries in Europe, Asia, America, Latin America, etc., and corresponding evaluation standard system has been developed for different building types and functions.

Peroration

In recent years, when China's green buildings achieve leapfrog development, they have also encountered misunderstandings, such as simply piling energy-saving equipment, or blindly imitating foreign models, resulting in poor actual operation results. With the rapid development of digitization and the acceleration of building industrialization, the development prospect of green building in China is broad.

As the industry's leading building metal envelope supplier, mastercard focuses on green energy-saving new materials to empower China's manufacturing industry, is committed to the implementation of green, innovation, digital intelligence and other new development concepts into product research and development, manufacturing and application, to provide high-quality factory construction system solutions for China's manufacturing enterprises and many real industries, and actively promote the comprehensive development of green buildings in China.
