Research on Green Building and HVAC Design in the Context of Smart Cities

In the current era of booming smart city development, green buildings have emerged as a pivotal component of sustainable urban construction. As HVAC (Heating, Ventilation, and Air Conditioning) systems represent a significant portion of total building energy consumption, their design optimization is of profound significance to the efficacy of green architecture. This paper focuses on the background of smart cities and deeply analyzes the close relationship between green buildings and HVAC design. It elaborates on the basic concepts of smart cities and green buildings, as well as the correlation between the two, while defining the requirements and principles of HVAC design regarding energy efficiency, environmental protection, comfort, and intelligence. Key technologies—including high-efficiency energy saving, renewable energy utilization, intelligent control, and the selection of green materials and equipment—are discussed in detail. The objective is to provide theoretical support and practical guidance for HVAC design within green buildings in smart cities, promoting the transformation of the construction industry toward energy-saving, environmentally friendly, and intelligent directions, thereby facilitating the achievement of sustainable development goals for smart cities.
