Ecological architecture and green plants?

Ecological architecture is closely related to green plants, and the treatment of every detail is crucial, which needs to be combined with actual situation and professional knowledge. Zhong Da Consulting Company will explain ecological architecture and green plants for you.

It is human nature to pursue health and happiness. With the development of economy, the urban population is increasing, the scale of the city is also increasing, various high-rise buildings are mushrooming, the development of high technology and the extensive use of modern building decoration materials make the urban space become an indifferent world surrounded by reinforced concrete, which makes people far away from nature, worsens the urban ecological environment, and makes the urban space environment more and more inhuman, which greatly harms people.

In this context, people began to pay attention to green buildings. "A building that provides healthy and comfortable space for human activities, at the same time makes the most effective use of resources and has the least impact on the environment" is an internationally recognized definition of green building. It is the concrete application and practice of sustainable development strategy in the field of architectural design. Plants have also become the main form of building greening, so the correct and reasonable ecological use of green plants has accelerated the process of realizing ecological and greening of buildings, and provided a guarantee for human beings to better live in harmony with nature.

I. Ecological architecture

The so-called ecological building is to regard the building as an ecosystem. Its essence is to integrate a large number of people into a super building to live, organize (design) various physical elements of the internal and external space of the building, so that materials and energy can be transformed in an orderly cycle within the building ecosystem, and an efficient, low-consumption, waste-free, pollution-free and ecologically balanced building environment can be obtained.

From the perspective of architectural design, there are two main tendencies. The first is to integrate architecture into nature. The second is to introduce nature into architecture, use high-tech knowledge to promote ecological architecture and naturalize artificial environment. Architecture is an important part of residential area. In the period of rapid urban development in China, the eco-architectural design with the harmony of people, architecture and nature has gradually merged into the mainstream of design, and eco-architectural design has become a research hotspot.

Second, the role of green plants in ecological architecture

Significance of building greening: Beautiful environmental greening is an inseparable part of the external space of a good building complex. It can not only change the face of the city, but also play an extremely important role in improving the climate, beautifying life and improving the visibility of greening.

Green buildings with three characteristics of energy saving, health, comfort and integration with nature have been tried and implemented in various types of buildings all over the world, and have also been successfully applied in Shanghai, Chongqing, Beijing and other big cities. However, at present, there are few systematic studies on the impact of greening on the environment of green buildings in China, and there is no special study on the greening system of green buildings, which can not meet the needs of the current greening development of green buildings. In 2004, a demonstration building of green ecological buildings and a green demonstration area were built in Shanghai. Taking Shanghai as an example, the greening system of green buildings was studied by means of field measurement, expert consultation and data extraction from plant resource information database. The results are as follows:

(1) Different plant species and hierarchical structures of outdoor greening plant communities have different effects on the outdoor environment of green buildings. Generally speaking, the ecological function of plant community with rich hierarchical structure is better, and the ecological benefit of lawn with simple hierarchical structure is worse. Therefore, if there are no special requirements, the multi-layer structure of trees, shrubs and grasses should be given priority in the greening process, and the corresponding functional communities should be selected in areas with different functional requirements. (2) Indoor greening can reduce indoor co_2 concentration by 8. 1% and indoor floating dust content by 6 1.6% on average, but it has little effect on indoor temperature and humidity. Therefore, green buildings should make full use of indoor space for greening. (3) Roof greening can reduce the average external surface and internal surface of the roof by 24.6℃ and 5.4℃ respectively in summer, and increase the average internal surface and external surface of the roof by about 3℃ in winter. At the same time, it can increase the relative humidity of the air on the outer surface of the roof by 12.5% on average, which is beneficial to building energy saving and creating a healthy and comfortable environment.

(4) The air humidity 0.2m away from the vertical greening wall is 1%- 1.9% higher than that of the bare wall, and the air humidity 0m away from the wall is 6.7%-9.2% higher than that of the bare wall. The temperature 0.2m away from the wall is 0.4℃-0.9℃ lower than that of the bare wall, and the temperature 0m away from the wall is 5.3℃-6.6℃ lower than that of the bare wall. There is little difference in cooling and humidifying ability of different vertical greening materials; The influence of vertical greening on indoor temperature is not obvious in the morning, but more obvious in the afternoon.

(5) The evaluation index system and evaluation model of green building greening are established by using analytic hierarchy process.

(6) Through expert consultation, the index weights of each level of green building greening evaluation system are obtained, and the weight coefficients of ecological function and landscape function are not much different, which shows that people have paid equal attention to the ecological benefits and landscape effects of greening plants.

(7) The green space system of Shanghai Eco-office Demonstration Building and Ganquanyuan Residential District was evaluated, and the results showed that the green space system of the demonstration building was evaluated as a whole.

The price score of 7.0 is a high-grade greening system, which is a high-quality greening system suitable for green buildings, but vertical greening needs to be strengthened and improved. The evaluation score of Ganquanyuan residential area greening system is 5.0, which belongs to the general grade greening system. Without roof greening, vertical greening needs to be strengthened and improved.

(8) Recommended plant species and functional plant communities suitable for green building greening in Shanghai. The benefit of building greening is consistent with the theme of green building, so we should make full use of building space for greening. Different plants should be selected according to different requirements when building greening.

Plants have many ecological functions, such as carbon and oxygen balance, transpiration and heat absorption, dust absorption, bacteria reduction and noise reduction, water conservation, soil and nutrient circulation activation, biodiversity maintenance, landscape function and disaster prevention and reduction. In the application of plants, we should not only plant plants, or simply pursue quantity, but also guide plants to balance the metabolism in cities more accurately, which requires reasonable selection of tree species and configuration to achieve the goal. Choosing tree species with high ecological function is the key to determine whether the ecological function of urban landscape plants can be played efficiently. The design of green space system in residential area is not that the more plants, the better the ecological benefits, but that we need to know enough about the characteristics of plants to make them suitable for sites and trees.

With the acceleration of urbanization, people put forward higher requirements for the environment of the building itself and the impact of the building on the environment. As an organic part of architecture, building greening can not only beautify the appearance of the building, improve the urban environment, but also reduce the energy consumption of the building. The correct and reasonable ecological utilization of green plants accelerates the process of realizing ecological green buildings and provides a guarantee for human beings to live in harmony with nature better.
