Application of Green Idea in Energy-saving Design of Building HVAC System

With the sustainable development strategy of our country attracting more and more attention, green projects are also designed to all kinds of industries, including construction. In the case of housing construction, the HVAC system is, to some extent, the most energy-intensive projects in the construction process. In order to meet the country’s sustainable development strategy to meet the practical require- ments of sustainable development, the need to green energy-saving environmental protection technology applied to the HVAC system, and the continuous development and popularization, from the country through the success of energy saving and envi- ronmental protection tech- nology to reduce the HVAC system of the energy con- sumption, which makes the building energy consumption to a minimum. HVAC works in the entire construction project have a pivotal role, so HVAC project green energy-saving design in the green building development indispensable. This paper explains the concept of green energy saving design of HVAC project and illustrates the key of green energy saving technology in HVAC design under construction industry. The paper analyzes the HVAC design of Guangzhou Library as an example.
