Assessment of natural ventilation in residential buildings: A case study of senior staff quarters, Obanla, Federal University of Technology, Akure, Nigeria.
This paper assesses natural ventilation in residential buildings to achieve passive cooling for thermal comfort within the buildings interiors. Non-probability method of sampling was adopted in which two samples were selected deliberately from a homogeneous population. The two samples were replica of the two building typologies in the staff quarters. Data were gathered through structured observation method and analyzed for factors that affect natural ventilation. Temporal users perceptions about natural ventilation provided in the understudied buildings were also obtained through oral interviews. Area and percentage of openings, floor areas and length to depth ratio of the buildings were calculated. Total area of openings was compared to the total floor area of the ventilated space, and the result was compared with the national and international standards on natural ventilation in buildings. The result shows that opening areas provided in the buildings are adequate for natural ventilation but users of these buildings still depend on fan and air conditioners for body cooling except on few cold periods. Some factors affecting natural ventilation such as envelope design, internal planning and room layout are inadequate. Consequently, these factors should be considered alongside other measures when designing buildings in order to have adequate natural ventilation for thermal comfort. Key words: Natural ventilation, residential buildings, thermal comfort, cooling, energy
