Combined Use of Wind-Driven Rain Load and Potential Evaporation to Evaluate Moisture Damage Risk: Case Study on the Parliament Buildings in Ottawa, Canada

Parts of the building envelope that frequently receive high amounts rain are usually exposed to a higher risk deterioration due moisture. Determination such locations can thus help with assessment moisture-induced damage risks. This study performs computational fluid dynamics (CFD) simulations wind-driven (WDR) on Parliament buildings in Ottawa, Canada. Long-term time-varying wetting load WDR and potential evaporation considered according several years meteorological data, this cumulative is proposed as fast method identify critical periods. The results show that, Center Block buildings, façades lower towers facing east most WDR, together corners main tower. Periods larger than observed, indicating deposited may lead moisture accumulation envelope. During these periods up months, air temperature repeatedly drop below freezing point, which poses freeze–thaw damage. First future risks indicates an increase at moderate increases temperature, but found for temperature.
