EVALUATING NATURAL VENTILATION EFFECTS OF ATRIUM IN A SUBTROPICAL VERNACULAR STREET-HOUSE IN TAIWAN

摘要

Vernacular building always reflects the obvious characterization of the indigenous culture and lifestyle where people lived to cope with the severe climate without modern materials. Traditional street-house is one of the vernacular building types in Taiwan. The objective of investigation is conduct on-site measurements for evaluating the natural ventilation effects from atrium in a subtropical vernacular street-house in Taipei.rnThe results showed that the wind velocity and air temperatures in the semi-outdoor and outdoor space were higher than that in atrium spaces. In summer, atrium space could create a stack effect to enhance the overall ventilation of indoor air cycling and interior comfort. In autumn, atrium space provided thermal insulation effect. This research indicated vernacular street-house atrium could be used as buffer zone for microclimate comfort. These findings can be used to explore the influences of atrium modifications on vernacular street-house for achieving an effective microclimate comfort in subtropical spaces.
