Comprehensive energy-saving green building China is just around the corner

After the green building adopts comprehensive energy-saving measures, it is completely feasible to achieve the 50% energy-saving goal. The incremental cost can be recovered through the saved energy costs in 3-5 years, and the green building in China is just around the corner.

In recent years, China's energy consumption is growing rapidly, energy consumption is high, and energy efficiency is low. On April 1, 2008, the revised Energy Conservation Law will be officially implemented. Among them, Article 4 clearly stipulates that “the state implements the basic national policy of saving resources, and implements the energy development strategy of saving and developing simultaneously and putting conservation first.”

This means that whether it is policy or public opinion, energy conservation and emission reduction, and environmental protection are inevitable development trends. Buildings are a field of high energy consumption. Under the guidance of new energy conservation laws and related policies, green buildings are getting closer and closer to us.

The American Society for Testing and Materials (ASTM) defines “green buildings” as “a building that provides performance requirements for a particular building that is continuously eliminated during and after construction and for a specific useful life. Interference in the function of the region and the global ecosystem, and can continue to improve."

The building will also breathe

Green buildings must first have the most basic safety, namely fire prevention, anti-theft and electromagnetic safety. Electromagnetic safety problems are especially easy to ignore. The use of a large number of non-linear devices in life can lead to harmonic pollution and electromagnetic interference, which not only increases the system power consumption, but also causes the risk of fire in the power system. Therefore, when selecting electrical equipment, products that have passed the national electromagnetic compatibility standard are used as much as possible, and filtering technology can also be used for centralized management at the power distribution cabinet.

The quality of indoor air is an important factor affecting human health. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines “qualified indoor air quality” as “a known pollutant that has not reached the concentration of damage determined by the authority. Most exposed people (80% or more) have no discomfort." There are some sources of pollution in buildings, including outdoor pollutants, building plants, interior decoration materials, building systems and equipment, household appliances, consumer products, occupants and their activities, all of which affect indoor air quality.

Therefore, the green building should be a building that breathes, providing 30 cubic meters of fresh air per hour. For single buildings, the use of wind environment simulation technology not only ensures good natural ventilation, but also reduces the use time of refrigeration and air conditioning. For large buildings, mechanically assisted ventilation is required. The purpose of natural ventilation and auxiliary ventilation is to dilute the emission of unavoidable pollutants produced by humans and materials, to control the level of indoor cockroaches (natural radioactive elements, carcinogenic, mainly from building materials), and to reduce the mildew in humid environments. opportunity.
