Natural Ventilation contributes to reducing CO2 emissions compared to traditional mechanical ventilation solutions. In addition to lower CO2 emissions throughout a building’s life cycle, the use of Natural Ventilation in e.g., schools and office buildings often results in savings in capital expenditure as well as operating costs. Natural Ventilation also improves the indoor climate, and several scientific studies show that improved indoor climate increases children’s learning and employees’ well-being and productivity.
