ABSTRACT As a result of recent research at the Eduardo Torroja Institute for construction sciences, a new wording for the indoor air quality (IAQ) regulations for dwellings included in the Spanish Building Code has come into force with the main goal of adapting required ventilation rates to real needs to consequently achieve a reduction of energy demand with no negative impact on indoor air quality or on condensation risk. This paper summarises the research that was carried out to assess the variation in the surface condensation risk due to the reduction of the ventilation rates. A method to assess the influence of variations in ventilation on surface condensation risk was adapted. Results show how it should be possible to achieve target CO2 concentration values in addition to not significantly increase the risk of surface condensation.

较低通风率对表面冷凝风险的影响：以西班牙法规对室内空气质量要求的提案为例

摘要 作为 Eduardo Torroja 建筑科学研究所最近研究的结果，西班牙建筑规范中包含的住宅室内空气质量 (IAQ) 法规的新措辞已经生效，其主要目标是调整所需的通风率以适应因此，真正需要的是在对室内空气质量或冷凝风险没有负面影响的情况下实现能源需求的减少。本文总结了为评估由于通风率降低而导致的表面冷凝风险变化的研究。采用了一种评估通风变化对表面冷凝风险影响的方法。结果表明，除了不会显着增加表面凝结的风险之外，还应该如何实现目标 CO2 浓度值。
