Efforts to enhance the energy efficiency of heating, ventilation, and air conditioning (HVAC) systems have been bolstered by technical advancements and stringent regulations. However, HVAC systems not only emit during operation due to energy consumption but also have significant embodied emissions, which recent studies show can exceed those of the operational phase. This study introduces an optimization framework aimed at minimizing lifetime emissions—both operational and embodied—for ventilation systems, an area previously underexplored. The optimization framework incorporates detailed calculations of pressure drop, fan power and newly developed life cycle ventilation inventory data with a life cycle assessment perspective.

使用基于生命周期的方法优化考虑运营和隐含排放的通风系统


技术进步和严格的法规为提高供暖、通风和空调 （HVAC） 系统的能源效率做出了努力。然而，HVAC 系统不仅在运行期间因能耗而排放，而且还具有明显的隐含排放，最近的研究表明，这可能超过运行阶段的排放。本研究引入了一个优化框架，旨在最大限度地减少通风系统的生命周期排放（包括运营和隐含排放），这是以前未被充分探索的领域。该优化框架结合了压降、风扇功率和新开发的生命周期通风库存数据的详细计算，并带有生命周期评估视角。
