_blank class=infotextkey>get=_blank class=infotextkey>楼间距（前后距）根据日照间距计算
_blank class=infotextkey>get=_blank class=infotextkey>所谓日照间距：指前后两排_blank class=infotextkey>get=_blank class=infotextkey>南向_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋之间，为_blank class=infotextkey>get=_blank class=infotextkey>保证后排_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋在冬至日底层_blank class=infotextkey>获得_blank class=infotextkey>不_blank class=infotextkey>get=_blank class=infotextkey>低于一_blank class=infotextkey>get=_blank class=infotextkey>小_blank class=infotextkey>时的满窗日照而_blank class=infotextkey>get=_blank class=infotextkey>保持的_blank class=infotextkey>最_blank class=infotextkey>get=_blank class=infotextkey>小间隔_blank class=infotextkey>get=_blank class=infotextkey>距离。
日照间距的计算方法：
以_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋长边向阳，民冶_blank class=infotextkey>村委_blank class=infotextkey>get=_blank class=infotextkey>楼，_blank class=infotextkey>get=_blank class=infotextkey>朝阳向正_blank class=infotextkey>get=_blank class=infotextkey>南，正午太阳照到后排_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋底层窗台为依据来_blank class=infotextkey>get=_blank class=infotextkey>进行计算。
如居室所需日照_blank class=infotextkey>时数增加_blank class=infotextkey>时，其间距就相应加_blank class=infotextkey>get=_blank class=infotextkey>大，或者当_blank class=infotextkey>get=_blank class=infotextkey>建筑_blank class=infotextkey>get=_blank class=infotextkey>朝向_blank class=infotextkey>_blank class=infotextkey>不是正_blank class=infotextkey>get=_blank class=infotextkey>南，其间距也_blank class=infotextkey>get=_blank class=infotextkey>有所_blank class=infotextkey>get=_blank class=infotextkey>变化。在坡_blank class=infotextkey>get=_blank class=infotextkey>地_blank class=infotextkey>get=_blank class=infotextkey>上_blank class=infotextkey>get=_blank class=infotextkey>布置_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋，在同样的日照_blank class=infotextkey>get=_blank class=infotextkey>要求_blank class=infotextkey>get=_blank class=infotextkey>下，_blank class=infotextkey>get=_blank class=infotextkey>由于_blank class=infotextkey>get=_blank class=infotextkey>地形坡度和坡向的_blank class=infotextkey>不同，日照间距也_blank class=infotextkey>get=_blank class=infotextkey>会随之_blank class=infotextkey>get=_blank class=infotextkey>改变。

由图可知：tanh=(HH1)/D,由此得日照间距应为：D=(HH1)/tanh；
式_blank class=infotextkey>get=_blank class=infotextkey>中：h—太阳_blank class=infotextkey>get=_blank class=infotextkey>高度角
H—前幢_blank class=infotextkey>get=_blank class=infotextkey>_blank class=infotextkey>get=_blank class=infotextkey>房屋檐口至_blank class=infotextkey>get=_blank class=infotextkey>地_blank class=infotextkey>面_blank class=infotextkey>get=_blank class=infotextkey>高度；

D日照间距
当然也_blank class=infotextkey>get=_blank class=infotextkey>可以根据日照间距_blank class=infotextkey>get=_blank class=infotextkey>系数换算过来。_blank class=infotextkey>在这里_blank class=infotextkey>get=_blank class=infotextkey>我们设置日照间距_blank class=infotextkey>get=_blank class=infotextkey>系数为L
根据日照间距_blank class=infotextkey>get=_blank class=infotextkey>系数L=D/（HH1） 换算出D=L×（HH1）
得出：(HH1)/tanh= L×（HH1） 1/ tanh=L tanh=1/L
日照间距的计算_blank class=infotextkey>get=_blank class=infotextkey>公式：日照间距D= L×（HH1）
也_blank class=infotextkey>get=_blank class=infotextkey>就是说，得首先得知前幢_blank class=infotextkey>get=_blank class=infotextkey>楼的檐_blank class=infotextkey>get=_blank class=infotextkey>高，_blank class=infotextkey>get=_blank class=infotextkey>才能计算离_blank class=infotextkey>get=_blank class=infotextkey>你家几米建_blank class=infotextkey>get=_blank class=infotextkey>房对_blank class=infotextkey>get=_blank class=infotextkey>自己_blank class=infotextkey>get=_blank class=infotextkey>房间日照_blank class=infotextkey>get=_blank class=infotextkey>有无_blank class=infotextkey>get=_blank class=infotextkey>影响。
另外，还得看日照是否_blank class=infotextkey>get=_blank class=infotextkey>满足_blank class=infotextkey>get=_blank class=infotextkey>大寒日_blank class=infotextkey>get=_blank class=infotextkey>2_blank class=infotextkey>get=_blank class=infotextkey>小_blank class=infotextkey>时的日照_blank class=infotextkey>时长。 [1]
