Is Green Building A Future Coexists with The Environment, or Is It the Evolution Direction of Contemporary Engineering?

What is Green Building?

The main concept of green building is "sustainable development". It needs to conform to the principle of environmental friendliness in the whole life cycle of the use process, from site selection, architectural design, operation and maintenance to reconstruction and demolition. The birth of green building, in fact, it is closely related to the environmental protection issues that the whole world is paying attention to. People try to strike a balance between architecture and nature. Green building upholds the key principles of:

• Reduce waste in construction and design
• Designed with recycled materials
• Use recycled green building materials (or wood and stone natural materials) during construction
• Reduce energy consumption as the main goal

Buildings are the largest energy consumers in the world. Under the crisis of global warming, "energy saving and carbon reduction" has become a common development goal of cities around the world. Countries have come up with ways to save energy and reduce carbon emissions. The development of "green buildings" is also a part of the joint efforts of all countries under the consensus of energy conservation and carbon reduction.

The energy consumption and greenhouse gas emissions of buildings account for one-fourth to one-third of the world's total energy consumption. According to a report by the WorldWatch Institute, buildings in the United States consume more than 65% of the electricity in the United States and bring about 30% of the greenhouse effect in the United States; buildings in the United Kingdom account for 30% of the UK's carbon dioxide emissions and 56% of the water. quantity. Under the torrent of "energy saving and carbon reduction", the "green" craze began to spread to the construction industry. Governments of various countries have included green buildings in the development priorities of countries and cities, hoping to reduce carbon dioxide through the implementation of green buildings that save energy and reduce carbon emissions and the goal of reducing energy consumption.

Green building technology compared with traditional buildings, there are huge business opportunities behind green buildings, including the application of many new materials, new technologies, and new fields. According to a 2010 study by Lux Research, the green building-related technology market reached US$144 billion in 2010, and is expected to grow to US$277 billion in 2020, with a CAGR of 6.1%. At present, the world's major international manufacturers have also invested in the development of green building-related technologies, and have applied them in many cities to solve problems such as energy consumption and carbon dioxide emissions. At the same time, they have also made considerable profits.

Green building has brought many new business opportunities to the traditional construction industry, and its application spans many industries. Therefore, the future technological development trend of green building has also become the focus of attention from all walks of life. Green building development trends to discuss the future technical development trends of green buildings, the most important thing is to find out the development trends of green buildings. Only technologies that conform to the development trend can continue to develop on the road of long-term technology research and development. Being in the latest technology application range can also meet future market needs and successfully grasp business opportunities.

The concept of carbon reduction in buildings has evolved from "low carbon" to "zero carbon". Issues related to "circulation" and "full life cycle" are booming. Countries are starting to think about carbon reduction from the source of buildings. For example, advanced countries such as the United Kingdom, the Netherlands, and Sweden have successively emerged zero-carbon communities or zero-oil communities in recent years. In particular, the latest building regulations in the United Kingdom stipulate that all new buildings must be zero-carbon emissions from 2016; Promoted the "Recycling Society Promotion Act" and established a waste network platform to "match" waste. In 2010, the website drove the recycling market of environmental protection resources in industries including automobiles, food, non-ferrous metals, packaging containers, and construction industries. 400 billion yen; Mainland China also launched the first zero-carbon community.

The cross-field application of construction is increasing. Under the low-carbon trend of the construction industry, many non-construction industry operators enter the construction market with high-tech and low-carbon technologies. Such as building greening applications of agriculture and forestry industry, including green roofs, green walls, plant factories, etc.; energy management applications of information and communication industry, such as using sensors to monitor energy consumption and real-time control of building energy consumption; biological treatment of biotechnology industry System applications, including "water, mushroom, biogas, fertilizer integrated sewage treatment technology" of JT Ecodesign Company of the United States, "grassland perennial plant biomass power generation" of the U.S. Land Research Institute, and "Biofiltration of Rainforest Ecological Model" of Sweden "system" etc.; building management services for the intermediary industry, such as Benin uses the carrion left over from the slaughterhouse to send it to the farm to cultivate maggots, and then supplies it to fish and poultry farms, and uses the generated biogas to generate electricity. The impact of the trend of cross-field application of buildings is that various fields are scrambling to invest in the development of green building-related technologies and stepping into the green building industry.

Future Trends of Green Building Technology

When the opportunity for green building transformation is opened, the future technological development trend is becoming clearer, and technologies and concepts that were previously unimaginable have been applied to green buildings. Just when various industries began to knock on the door of this traditionally high-barrier-to-entry industry, it was also predicted that green buildings would take root and flourish everywhere in the future; buildings also began to change from "be bigger" to "be more expensive " turn to "be greener" and "be more energy-efficient".
