Building Envelope Energy Retrofit

加拿大有大量的现有建筑物。由于没有任何节能政策，特别是那些建于50年代初，60年代和70年代，这是一个驱动器，导致我们的建筑物的更新。改造为加拿大建筑业带来了重大的经济机遇。 目前的挑战是评估这些能源改造的湿热性能的风险评估。尽管在建筑物性能方面有许多进步，但仍然必须努力减少能源消耗，使其成为节能和具有成本效益的建筑。 由于缺乏改造的误解，如何有效和安全地改造建筑物，并支持加拿大正在进行的努力，以减少温室气体排放和能源使用，建议看看更好的能源战略改造的商业和住宅建筑。 这将通过实验室测试，建模和现场监测来评估其能量和湿热性能。 这项拟议的研究计划需要提供必要的科学数据和分析，以表征现有建筑物的能源和湿热性能。研究活动从构件和系统到整个建筑性能。这项工作符合零能源家庭和加拿大向低碳未来的过渡，能源在其中发挥着重要作用。拟议的方案侧重于两个主题。 第一个主题（主题A）是现有商业和大型建筑物的改造：湿热和能源性能。第二个主题（主题B）是现有住宅建筑的改造：湿热和能源性能。长期目标是更好地了解整个建筑物对热量，空气和水分（HAM）的反应，并使用整体和综合的方法研究其对舒适度，能耗和外壳耐用性的影响。 这项研究最终将引导我们建造负担得起、耐用、更健康、更舒适的建筑。* 主题A：制定新的能源和湿热战略，从外部和内部改造现有商业建筑，以改善其能源和湿热性能。* 主题B：制定新的能源战略，对现有住宅建筑和高R墙体组件进行改造，以实现成本效益和能源效率。*设定的目标是朝着持续改善建筑物的能源和湿热性能迈出的一步，朝着近，净零，零准备能源或碳中性能源家庭迈进。 由于能源要求更加严格，需要在这一领域进行研究，以维持能源性能的改善，这意味着负担得起的，耐用的，更健康和更舒适的建筑。

Canada has a huge existing buildings stock. Since there were built without any energy efficiency policies, especially those built in early 50s, 60s and 70s, this is a driver that lead us to building's renovation. The retrofit represents a significant economic opportunity for the construction industry within Canada. The challenge is to evaluate the risk assessment of these energy retrofit on the hygrothermal performance. Despite there are many advances in buildings performance, but still effort has to be made to reduce the energy consumption to make them energy-efficient and cost-effective buildings. With the lack of retrofit misunderstanding on how to efficiently and safely retrofit buildings and to support ongoing efforts in Canada to reduce GHG emissions and energy use, it is proposed to look at better energy strategies retrofit for commercial and residential buildings. This will be done through laboratory testing, modeling and field monitoring to asses their energy and hygrothermal performance. This proposed research program is needed to provide the scientific data and analysis necessary to characterize the energy and hygrothermal performance of existing buildings.******The research activities span from components and systems to the whole building performance. This work goes in line with zero-energy ready homes and the Canada transitions to a low-carbon future for which energy plays a major role. The proposed program focused on two main themes. The first theme (Theme A) is on Retrofit of the Existing Commercial and Mass Masonry Buildings: hygrothermal and energy performance. The second theme (Theme B) is on Retrofit of the Existing Residential Buildings: hygrothermal and energy performance.***The long-term objectives are to develop a better understanding of the response of whole building to Heat, Air and Moisture (HAM) and study their effect on comfort, energy consumption and enclosure durability using a holistic and integrated approach. The study will eventually lead us to affordable, durable, healthier and more comfortable buildings. This is supplemented by several specific themes having short-term objectives: ***Theme A: Develop new energy and hygrothermal strategies to retrofit existing commercial buildings from the exterior and interior in order to improve their energy and hygrothermal performance. ***Theme B: Develop new energy strategies retrofit for existing residential buildings and high-R wall assemblies in order to be cost-effective and energy-efficient.******The set objectives are a step towards a continuous improvement of the energy and hygrothermal performance of buildings toward Near, Net-zero, Zero-ready energy or carbon neutral energy homes. Since the energy requirements are more stringent, research in this field is needed in order to sustain the energy performance improvement, which means affordable, durable, healthier and more comfortable buildings.
