本文对多层住宅建筑节能方法进行了研究。该研究在加拿大蒙特利尔（45°N）进行。考虑的所有配置都假设郊区环境，允许高太阳照射，没有邻近建筑物或外部周围物体（如树木）的阻碍。能源绩效是通过需求方的能源消耗与供应方的集成光伏系统发电之间的平衡来衡量的。本研究考虑通过增加发电潜力来增强供应方。公寓建筑的设计具有高能源效率，并符合被动式太阳能设计原则。调查的建筑物包括低层（3-5层）、中层（6-9层）和高层（最高12层），每层有8套公寓。考虑到每个住宅单元屋顶面积的减少，除了屋顶表面外，还考虑将所有光伏系统集成到立面中。使用EnergyPlus建筑模拟程序的模拟结果表明，公寓建筑在供暖和制冷方面相对节能，同时允许高水平的住宅密度，但其太阳能潜力有限。根据目前的研究，如果屋顶设计针对太阳能发电进行优化，一座三层楼的建筑可以产生约96%的总能源消耗。在3层以上，需要采取额外措施来提高能源生产。在50%的南立面和80%的东西立面表面区域安装光伏系统，以及加强屋顶表面设计（折叠板），使电力生产高达90%的能源使用的4层楼的建筑减少与增加的高度为50%的12层。该研究表明，投资先进的外观设计，（如折板幕墙）可大幅增加发电量，并在八层以上的建筑物中实现净零和剩余能源状态。
This paper presents a study of energy performance enhancement methods in multistory residential buildings. The study is carried out for Montreal location, Canada (45°N). All configurations considered assume a suburban environment that allows high solar exposure and no obstruction from adjacent buildings or external surrounding objects such as trees. Energy performance is measured by the balance between energy consumption, on the demand side, and electricity production by means of integrated PV systems, on the supply side. The present study considers enhancement of the supply side by increasing electricity generation potential.Apartment buildings are designed to be highly energy efficient and to conform to passive solar design principles. The buildings investigated include – low rise (3–5 floors), mid-rise (6–9 floors) and high-rise (up to 12 floors), with eight apartments per floor. All Integration of PV systems in façades, in addition to roof surfaces, is considered, in view of the reduced availability of roof surface per dwelling unit. The results of simulations employing the EnergyPlus building simulation program indicate that apartment buildings are relatively energy efficient for heating and cooling, while allowing a high level of residential density, but their solar potential is limited. Under the present study, a building of three stories can generate about 96% of its total energy use, if the roof design is optimized for solar energy generation. Above 3 floors, additional measures are required to enhance energy production. Implementing PV systems on 50% of south façade and 80% of east and west façades surface areas, in addition to enhanced roof surface design (folded-plate), enables electricity production of up to 90% of energy use of a 4-story building reducing with increasing height to 50% for 12 stories.The study indicates that investment in advanced design of façades (such as folded-plate curtain walls) can substantially increase electricity production and achieve net zero and surplus energy status in building over eight stories high.
