提高建筑群的能源效率是减少气候变化的主要工具之一。提高建筑围护结构的气密性有一个副作用——需要更高的通风率，这反过来又导致更高的能源费用和降低的室内空气质量。这就造成了能源效率-室内空气质量的困境。本研究评估了困境对国内生产总值（GDP）的影响。应用系统动力学建模来回答这个问题。以拉脱维亚的教育体系和劳动力市场作为案例研究。模拟结果表明，即使拉脱维亚的所有教育建筑都提高了能源效率性能并显着降低了室外二氧化碳水平，但如果不使用机械通风，室内二氧化碳含量仍然很高。最好的解决方案是提高能源效率，同时通过机械通风提供良好的室内空气质量，因为GDP的增长为进一步的能源效率措施提供了资金来源。
Increased energy efficiency of the building stock is one of the main tools to reduce climate change. Improved airtightness of the building envelope has a side effect - the need for higher ventilation rates which, in turn, lead to a higher energy bill and reduced indoor air quality. This creates an energy efficiency - indoor air quality dilemma. This study evaluates the dilemma impact on the gross domestic product (GDP). System dynamics modelling is applied to answer this question. The education system and labour market of Latvia is used as the case study. Simulation results show that even if all education buildings in Latvia have improved energy efficiency performance and have a significant reduction of outdoor CO2 level, indoor CO2 is very high if no mechanical ventilation is used. The best solution is to increase energy efficiency while providing good indoor air quality by operating mechanical ventilation since the increase in GDP provides financial sources for further energy efficiency measures.
