This thesis aims to investigate the impact of green architecture features on the well-being of children and staff in Dutch preschools, addressing a gap in previous research. It considers six forms of well-being: physical, emotional, environmental, financial, personal development, and work-life balance. Seven green architecture features are outlined: energy efficiency, water efficiency, environmentally preferred building materials, waste reduction, toxic reduction, indoor air quality, and smart growth. Greenery in architecture is noted to reduce stress, promote social interactions, support child development, stimulate personal growth, and encourage physical activity, with potential drawbacks such as allergic reactions and excessive sunlight exposure.

Four Dutch preschools, Open Air School, Het Volle Leven, IKC De Kleine Kapitein, and De Avonturier, are analyzed, highlighting the impact of Green Architecture features on the well-being of the children and staff and how this is visible in architectural elements. Common green architecture implementations include biodiversity, waste reduction, strategic window placement for airflow and natural light, and multifunctional layouts supporting interaction and ventilation. These features positively influence energy efficiency, indoor air quality, and smart growth, ultimately enhancing physical and emotional well-being.
