the Influence of Building Ground Floor Elevation on Summer Campus Microclimate in Northern Guangxi
To study the influence of building ground floor elevation on the campus microclimate in summer in northern Guangxi,a group of ground floor elevated teaching buildings in a university in northern Guangxi was selected as the research object.The microclimate data of the campus in summer were obtained by field measurement to analyze the effect of the building ground floor elevation on the microclimate,and the effect of different elevation heights on the thermal comfort of the campus was compared by a numerical simulation.The results show that:compared with the direct sunlight outside the elevated floor,the elevated floor has a cooling and humidifying effect,and its average cooling and humidifying effects are 2.3 ℃ and 4.18％respectively.The open elevated floor has a significant effect on improving the wind environment,with an average wind speed of 1.25 m/s;the physiological equivalent temperature(PET)value under the elevated floor is 12.8 ℃ lower than outside,creating a comfortable and stable space environment.When the elevation height is three m,the cooling and humidification effect and thermal comfort are the best;when the elevation height is five m,the ventilation effect reaches the best.The study results provide a reference for the planning and design of campus buildings and the improvement of campus microclimate comfort in northern Guangxi.
