The Ventilative Cooling Potential Tool developed by EURAC Research helps designers and engineers evaluate how effectively natural ventilation can cool a building during early design stages. 

Based on the IEA Annex 62 methodology and refined using equations from EN ISO 52016‑1:2017, the tool models a reference thermal and ventilation zone to estimate cooling potential under real contextual conditions. It accounts for factors such as envelope properties, internal gains, occupancy patterns and ventilation needs, providing a practical way to identify when and where ventilative cooling strategies can reduce reliance on mechanical systems. 

The approach is now integrated into Annex H of the forthcoming technical specification 'Ventilation for Buildings — Ventilative Cooling Systems — Design', ensuring consistency with European standards.
