楼房采光数学模型及应用

Model of lighting in choosing buildings and its application

城市在建商品住房常以高层建筑为主,其采光已成为消费者选房时着重考虑的因素之一.基于此,结合球坐标系和直角坐标系,考虑太阳高度角、太阳方位角及楼房的长宽高和影长等参数,建立楼房采光数学模型.借助Matlab软件求解出楼房采光效果及其相互影响的规律,可以得到不同房间全年的采光效果.

N ow adays, building lighting becomes one of the im portant factors for consum ers to consider choosingroom s, because the m ajority of com m ercial houses are high-rise buildings. By com bining the spherical coordinatesw ith rectangular coordinate system , a m athem atical model of building lighting is established in virtue of som e param eters, such as solar altitude, solar azim uth, the length, w idth and height of the buildings and length of buildings,shadow s. W ith the help of the softw are M atlab, solving different buildings, lighting effects in a sam e housing estateand finding the rule how they influence each oth er, people can get different room s, lighting effects throughout thew hole year.
