Building Envelopes and Insulation: The foundation of Passive House Design

建筑和设计越来越注重节能和可持续发展，在整个欧洲和美国，可持续发展的建筑正在成为标准。这一倡议的动力是，在工业化国家，高达40%的总能源消耗用于建筑，建筑能效的显著提高对能源消耗有相当大的影响。被动式住宅标准可以使新建筑的供暖和制冷能耗减少75%，翻新能耗减少95%。包括比利时、德国和美国在内的世界各地越来越多的城市，已经为新建筑的被动节能屋设计立法。如果加拿大想要在日益增长的被动式房屋运动中保持竞争力，我们必须在新设计、材料和建筑技术的开发和评估方面处于领先地位。目前的提案是亨伯学院与住宅和商业绝缘材料制造商ROXUL®Inc.的合作。在该项目中，Humber和ROXUL®将使用ROXUL®建筑和绝缘产品，结合加拿大多家制造商的标准建筑产品，设计和分析住宅建筑围护结构组件的热能性能。将进行分析，以期达到被动式住宅的能效标准。由此产生的热分析数据，包括组件的二维图纸和三维模型，将有助于ROXUL®向加拿大市场推广高性能建筑技术。该项目的成果将有助于将Humber College和ROXUL®确立为被动房运动的领导者，并将为双方在被动房行业内的未来倡议奠定基础。

Building and design is increasingly focused on energy conservation and sustainability and, across Europe and the U.S., sustainable buildings are becoming the standard. The impetus for this initiative is that up to 40% of the total energy consumption in industrialized countries is used for buildings, and significant improvement of the energy efficiency of buildings has considerable impact on energy consumption. The Passive House Standard can lead to improvements of up to 75% in the energy consumption for heating and cooling of new builds; and reductions of up to 95% for refurbishments. There is a growing list of cities worldwide that have legislated Passive House design for new buildings, including cities in Belgium, Germany and the United States. If Canada is to stay competitive in the growing Passive House movement, we must be leaders in the development and evaluation of new designs, materials and building technologies. The current proposal is a collaboration between Humber College and ROXUL® Inc, manufacturer of residential and commercial insulation materials. In this project, Humber and ROXUL® will design and analyze thermal energy performance of residential building envelope assemblies utilizing ROXUL® building and insulation products in combination with standard building products from a variety of Canadian manufacturers. Analysis will be performed with the intent to achieve Passive House standard for energy efficiency. The resultant thermal analysis data including 2-dimensional drawings and 3-dimensional models of the assemblies will aid ROXUL® in promoting high-performance building technology to the Canadian market. Results from this project will help establish Humber College and ROXUL® as leaders in the Passive House movement, and will be the foundation of future initiatives for both partners within the Passive House industry.
