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性，在整个欧洲和美国，可持续建筑正在成为标准。推动这一倡议的原因是，工业化国家高达40%的总能耗用于建筑，建筑能效的显著提高对能源消耗有相当大的影响。被动式房屋标准可以使新建建筑的供暖和制冷能耗降低75%；翻新费用最多可减少95%。世界上有越来越多的城市立法要求在新建筑中采用被动式房屋设计，其中包括比利时、德国和美国的城市。如果加拿大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和住宅和商业绝缘材料制造商ROXUL®公司之间的合作。在这个项目中，Humber和ROXUL®将设计和分析住宅建筑围护结构组件的热能性能，利用ROXUL®建筑和保温产品，结合来自各种加拿大制造商的标准建筑产品。将进行分析，以达到被动式房屋的能源效率标准。由此产生的热分析数据，包括2维图纸和3维组件模型，将有助于ROXUL®在加拿大市场推广高性能建筑技术。该项目的成果将有助于汉伯学院和ROXUL®成为被动房运动的领导者，并将成为被动房行业双方合作伙伴未来倡议的基础。

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.
