Abstract
This article presents the results of the exploratory study on indoor air quality in existing dwellings with traditional ventilation systems based on natural ventilation. A preliminary study of the most representative typology of the Spanish housing stock has been conducted and, based on it, twelve dwellings located in Madrid have been monitored in different periods. Monitored indoor air quality has been compared to that required in the regulations in Spain, the Código Técnico de la Edificación (Technical Building Code). According to the results of the research, 50 % of the monitored dwellings do not comply with the CO2-based air quality quantification offset in the regulations. Such non-compliance is primarily caused by high CO2 concentrations in winter, especially in bedrooms. These high concentrations and their seasonality are attributed to the interference of the occupant’s behaviour, influenced by weather conditions, that is affecting the efficiency of the existing natural ventilation systems.
本文介绍了基于自然通风的传统通风系统对既有住宅室内空气质量的探索性研究结果。对西班牙住房存量最具代表性的类型进行了初步研究，并在此基础上，在不同时期对马德里的12所住宅进行了监测。监测的室内空气质量已与西班牙法规Código t cnico de la Edificación(建筑技术规范)的要求进行了比较。根据研究结果，50%的监测住宅不符合法规中基于二氧化碳的空气质量量化抵消。这种不合规主要是由于冬季二氧化碳浓度高，尤其是卧室。这些高浓度及其季节性归因于受天气条件影响的居住者行为的干扰，这影响了现有自然通风系统的效率。
