The governing lateral force for designing tall buildings in Sri Lanka are wind loads. With Sri Lanka currently going through a rapid change in the skyline with the introduction of tall buildings is envisaged to have effects on the wind climate pattern. Thus it is of the utmost importance that wind climate studies are carried out in tall buildings. Remote sensing has been an improvement in in-situ monitoring and has proven to be a technological advantage in gathering data and providing valuable information for research as well as for improvement in the Construction industry.
This case study presents one of the simplest yet an effective way of setting up a remote wind monitoring system which can be used as a tool to study the behaviour of wind around tall buildings. The said system utilizes basic equipment which is readily available to provide readings at an adequate accuracy level of ±1m/s. But in an instance where high level of accuracy is needed, it can be achieved by simply using upgraded hardware with the same control logic.
The system can be modified further to capture acceleration readings. Wind data and the acceleration data can be obtained remotely and analysed, to give a comprehensive idea on how tall buildings react to high gusts of wind. This practical data obtained will help one to verify the theoretical simulations done during the design stage of high rise buildings or even change the existing concepts on how buildings react to winds. This work will be globally recognised as only very few buildings are presently monitored around the world
