Key findings of four years of research on Ventilative Cooling and how it is done

Over the course of the four-year research project of the IEA EBC Annex 62, Ventilative Cooling (VC) has been proven a robust and highly energy efficient solution to support summer comfort in both residential and commercial buildings. Furthermore our findings show that VC can be successfully applied in both cool and warm temperate climates. 

This paper concludes on how the application of Ventilative Cooling will become successful. It offers detailed insights on VC elements, their application and control strategies most commonly linked to well-operating VC systems. Beyond that hands-on information on algorithms for early stage air-flow estimation as well as key performance indicators, which should be considered, are stated. 

These key findings are of interest especially for researchers, architects, HVAC designers and facility managers striving after designing and operating energy efficient buildings making use of Ventilative Cooling to achieve indoor thermal comfort.
