A Case Study on the Influence of the Patio on the Indoor Environment in Summer in a Chinese Traditional Folk House
Traditional folk houses have been shown to provide examples of many useful design practices to control the effects of climate. This paper presents a case study on the influence of the patio on the indoor environment of a traditional folk house group in summer of 2007, named Zhangguying Village in Hunan Province. Measurements were made of indoor and outdoor air temperature, indoor and outdoor illuminance, indoor and outdoor air speed. The indoor air temperature was measured at a height of 2 m from floor level and the data were recorded every 5 minutes. The indoor air speed was measured at a height of 1.5m at 09:00 and 15:00 each day, taking the average value over 2 minutes of measurements recorded at 20 second intervals. The outdoor wind speed and temperature were measured by the portable weather station at the height of 10m and data were recorded at intervals of 20 minutes. The indoor and outdoor illuminance was measured by the luminometer at a height of 0.75 m at 09:30 and 15:30 each day. The results of temperature show that the temperature of the patio is lower than outdoor temperature but higher than that of rooms and the temperature contrast between outdoor and patio in the day is larger than that at night. The results of illuminance show that the illuminanee of the patio is lower than outdoor temperature but higher than that of rooms and the illuminance of rooms is lower than the national standards. The results of wind speed show the speed of the patio is similar as that of the hall and the stack effect of patio is not obviously. The results and analysis show some valuable conclusions: The patio, act as a buffer zone, can reduce the impacts of outdoor weather conditions to indoor thermal environment of rooms; The patio can improve the indoor lighting environment but the effect is too limited because that shading design is the primary consideration in this kind of climate; The patio is useful for natural ventilation, caused by wind pressure, in summer.
