Abstract

In the context of global energy structure transformation and the "dual carbon" goal, the low-carbon development of the construction industry, as a key area of energy consumption and carbon emissions, is imperative. The core of low-carbon buildings lies in optimizing design to reduce operational energy consumption, minimize environmental load, and achieve efficient resource utilization and ecological sustainability. Among them, the HVAC system, as the main component of building energy consumption, directly determines the overall energy efficiency level and living comfort of the building based on its energy-saving performance. This article focuses on renewable energy integrated HVAC systems for low-carbon buildings, system modeling and multi-objective optimization research, with a focus on key technical aspects such as diversified configuration of cold and heat sources, fresh air heat recovery strategies, and collaborative design of kitchen exhaust systems. At the same time, we will delve into the collaborative mechanism between passive design principles and active HVAC systems in ultra-low energy residential buildings, and propose a system solution that balances energy efficiency, comfort, and economy. The research results aim to provide feasible and replicable technological paths and design references for green and low-carbon housing, and to assist the high-quality development of China's construction industry towards energy-saving, low-carbon, and intelligent directions.
