Ventilation strategies for indoor air quality: comparative simulations

Using the Energy and Indoor Climate Visualizer, the performance of ten ventilation and cooling strategies are tested in four different climatic zones across Europe. Thermal comfort and indoor air quality (IAQ) are evaluated according to the EN15251 standard for the summer period. Results show that thermal comfort can be achieved by passive means in all four locations. Natural ventilation was capable of achieving a very good IAQ and a reduction in energy consumption in all locations, when compared with mechanical ventilation or mechanical cooling.
