AbstractBuilding codes and standards specifies pressure coefficient data for wind design of commercial roofing systems. It mostly derives the data from wind tunnel studies. Roofing community in North America has undergone much change over the last 25 years along with advances in ma-terial science, computer-aided design and engineering application. However, the wind tunnel data that was developed over two decades before can be said to be less appropriate to quantify wind induced loads of current roof coverings. Field measurements can benchmark the wind tunnel studies can prove valuable data to validate the current wind load provisions and the ex-isting roof cladding wind uplift test methods. A long term project has been initiated at the NRC, to collect the field performance of commercial roofs in three locations across North America, (1) Ottawa ? Canada (2) Mt Pleasant ? USA and (3) Rialto ? USA. This paper presents the data from the Ottawa Site.
