该项目研究了建筑几何的潜力，以最大限度地减少办公开发中的能源消耗。在多伦多（位于加拿大安大略省南部）的背景下，开发了五种不同的建筑几何形状来代表中型办公用房。用不同的设计参数考察了正方形、东西拉长的矩形、南北拉长的矩形、h形和十字形；如：窗墙比和外部静态太阳能控制装置（水平悬挑和垂直翅片）。应用IES VE软件对40种分析排列的年能耗结果进行预测。研究结果表明，能源利用值从一种形状到另一种形状的偏差相对较小。除此之外，窗户与墙壁的比例在建筑的能源使用模式上比其形状显得略显强势。遮阳设计特别有助于减少办公空间的冷却能源需求。总体而言，五个原型的能源性能符合单个建筑的长宽比（即紧凑性）。因此，该项目的研究结果有望为建筑师在设计办公大楼时利用建筑几何作为节能措施提供有用的指导。
The project investigates potentials of building geometry to minimize energy consumption in office developments. Five distinct building geometries are developed to represent mid-size office occupancies in the context of Toronto (located at southern Ontario, Canada). A square, a rectangle elongated on eastwest, a rectangle elongated on north- south, an H-shape, and a cruciform are examined with varied design parameters; such as: window to wall ratio and external static solar control devices (horizontal overhangs and vertical fins). The IES VE software is applied to predict the yearly energy consumption results for 40 analysis permutations. The outcome of this research shows that, the deviation of energy use values from one shape to another is relatively small. In addition to that, window to wall ratio appears slightly overpowering on the energy use pattern of a building than its shape. Shading design is found particularly helpful in reducing cooling energy demand in offices spaces. Overall, the energy performance of five archetypes is observed to comply with individual building aspect ratios (i.e. compactness). Thus, the findings of this project are expected to provide useful guidelines to the architects to utilize building geometry as an energy saving measure when designing office buildings.
