本文提出了一种方法，调查三个主要参数的影响，在设计两层住宅单元在不同的邻里布局，对太阳能利用潜力。这些参数是单个单元的几何形状、单元的密度和场地布局。研究了矩形和L形机翼之间夹角不同的情况。密度参数由分离的和多路复用的单元表示。平行行的单位的效果也进行了研究。场地布局包括一条笔直的道路和南北向的半圆形道路。EnergyPlus模拟包用于模拟由参数值组合组成的26种配置。影响进行评估，从参考配置的响应参数的变化-入射和透射照射的外墙和集成光伏发电。结果表明，总发电量取决于活跃的屋顶表面积，这是受形状和方向。与参考相比，某些配置的一些住房单元的发电量可增加50%。表面方向的变化，特别是在弯曲的布局中，可以使峰值发电时间延长至6小时。
The paper presents a methodology for investigating the influence of three major parameters in the design of two-storey housing units in different neighborhood layouts, on solar energy utilization potential. The parameters are geometric shapes of individual units, density of units and site layouts. Rectangular and L shape with different values of the angle enclosed between the wings of this shape are studied. The density parameter is represented by detached and multiplexed units. The effect of parallel rows of units is also studied. Site layouts include a straight road and south and north facing semi-circular roads. The EnergyPlus simulation package is used to simulate 26 configurations consisting of combinations of the parameter values. Effects are evaluated as the change from reference configurations of the response parameters – incident and transmitted irradiation of facades and integrated PV electricity generation. The results indicate that the total electricity generation is governed by active roof surface area which is affected by both shape and orientation. Up to 50% increase in electricity generation can be achieved in some housing units of certain configurations, compared to the reference. Variation of surface orientation, particularly in curved layouts enables the spread of peak electricity generation over up to 6h.
