If natural ventilation is to be incorporated in the design process from beginning to end, two main issues need to be addressed by architects: The first issue is local wind information, Wind Wheel represents prevailing wind direction, speed, frequency, temperature, and RH% graphically to help architects decide which direction of wind to block and which to allow in at any selected period of the year. The second issue is validating designs that serve the natural ventilation objectives of the architect, which is done when the form of the building starts to take shape. For this purpose, a technique that can visualize, measure and evaluate airflow patterns for different designs is presented here using a special wind tunnel. Vernacular Architecture incorporates these issues but has evolved over a long period of time. A working example from UAE vernacular architecture is presented using both the WW to identify wind patterns and the wind tunnel technique to see how vernacular ventilation elements work. These tools can be used to design more energy efficient modern buildings by helping architects develop new concepts and designs for openings, wind scoops and wind towers.
