The IPCC 2021 report predicts rising global temperatures and more frequent extreme weather events in the future, which will have different effects on the regional climate and concentrations of ambient air pollutants. Consequently, changes in heat and mass transfer between the inside and outside of buildings will also have an increasing impact on indoor air quality. It is therefore surprising that indoor spaces and occupant well-being still play a subordinate role in the studies of climate change. To increase awareness for this topic, the Indoor Air Quality Climate Change (IAQCC) model system was developed, which allows short and long-term predictions of the indoor climate with respect to outdoor conditions. The IAQCC is a holistic model that combines different scenarios in the form of submodels: building physics, indoor emissions, chemical-physical reaction and transformation, mold growth, and indoor exposure. IAQCC allows simulation of indoor gas and particle concentrations with outdoor influences, indoor materials and activity emissions, particle deposition and coagulation, gas reactions, and SVOC partitioning. These key processes are fundamentally linked to temperature and relative humidity. With the aid of the building physics model, the indoor temperature and humidity, and pollutant transport in building zones can be simulated. The exposure model refers to the calculated concentrations and provides evaluations of indoor thermal comfort and exposure to gaseous, particulate, and microbial pollutants.
《IPCC 2021 报告》预测未来全球气温上升和极端天气事件更加频繁，这将对区域气候和环境空气污染物浓度产生不同的影响。因此，建筑物内外的热质传递变化也将对室内空气质量产生越来越大的影响。令人惊讶的是，室内空间和居住者的舒适度在气候变化研究中仍然扮演次要角色。为了提高对此主题的认识，开发了室内空气质量气候变化（IAQCC）模型系统，该系统允许根据室外条件对室内气候进行短期和长期预测。IAQCC 是一个整体模型，它以子模型的形式结合了不同的情景：建筑物理学、室内排放、化学物理反应和转化、霉菌生长和室内暴露。IAQCC 允许模拟室内气体和颗粒浓度受室外影响、室内材料和活动排放、颗粒沉积和凝聚、气体反应和 SVOC 分配的影响。这些关键过程与温度和相对湿度密切相关。借助建筑物理学模型，可以模拟室内温度和湿度以及建筑区域内的污染物输送。暴露模型指的是计算出的浓度，并对室内热舒适度和对气态、颗粒状和微生物污染物的暴露进行评估。
