Open joint ventilated faÃ§ade (OJVF) is a passive constructive system widely used to ameliorate envelop of buildings, improving their energy efficiency. A laboratory model of a ventilated faÃ§ade with horizontal and vertical open joints was used to study thermal and fluid-dynamic behaviour of this system. Experimental Stereo Particle Image Velocimetry (Stereo-PIV 2D-3C) was applied to study the fluid dynamic performance of this model. In addition, thermal analyses were performed applying infrared thermography and air temperature monitoring inside the ventilated cavity.
A major concern of those wishing to limit the energy use in buildings is the growing trend towards installing air-conditioning in new and refurbished buildings. Building design, high thermal loads, and a desire for perceived comfort, contribute to an ever-growing demand for full air-conditioning. Therefore, to counter the impact on building energy use, it is essential that building design and operation is developed to minimise the use of air conditioning systems.
