Low-carbon energy-saving building green roof

Abstract

The invention discloses a low-carbon energy-saving building green roof which comprises a roof body, a solar power generation system and a greening pool are arranged on the roof body, a greening structure layer is arranged in the greening pool, the lower end of the outer wall of the greening pool is connected with a drainage pipe, one end of the drainage pipe is communicated with a water storage and drainage layer, and the other end of the drainage pipe is connected with a water storage tank. An automatic irrigation device and a light supplementing lamp are arranged on the greening pool, and the water inlet end of the automatic irrigation device is communicated with the water storage tank. Solar energy is converted into electric energy through the solar power generation system, then the electric energy is supplied to electric equipment on the green roof, energy conservation and environmental protection are achieved, rainwater is stored through the water storage tank, water is supplemented to plants in the greening pool through the automatic irrigation device, rainwater recycling is achieved, resources are saved, light is supplemented to the plants through the light supplementing lamp, and the environment-friendly effect is achieved. The whole building green roof is simple in structure and convenient and fast to operate, and the low-carbon and energy-saving effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly buildings, in particular to a low-carbon and energy-saving building green roof. Background technique [0002] With the rapid development of urban construction, the problem of air pollution in cities is becoming more and more serious. At present, many urban problems in the vast cities need to be solved. How to expand the green area in the limited urban space has become a new problem that people must face and solve. The current green buildings are mainly reflected in the use of materials and clean energy, but the building roof as a very important content has not received enough attention. In recent years, people have only begun to discover this hidden corner—the roof, also known as the "second Five facades". Roof greening can increase the area of ​​urban green space and improve the deteriorating human living environment space; improve the urban high-rise buildings and improve the stat...

AI Technical Summary

Problems solved by technology

However, there are still many defects in the existing green roofs of buildings: when the rainfall is large, the excess rainwater is directly discharged to the ground along with the drainage pipes, and the rainwater is not reused, which wastes water resources. To ensure the normal growth of plants, it is also necessary to water the green roof, which not only wastes resources, but also increases energy consumption and indirectly increases carbon emissions; at night or on cloudy days, the plants on the roof only perform respiration, which will also increase additional carbon emissions
