Low carbon retrofit of a single family house into multi-unit apartment building

Peel Passive House Consulting Ltd（PeelPHC）为开发商、建筑业主和设计专业人士提供咨询服务，帮助他们实现新建和现有建筑的被动房要求。 这些项目可以节省大量的碳，这是加拿大各地许多组织的主要目标之一。多伦多市的温室气体（GHG）减排目标要求对现有房屋采取实质性行动。2021年6月发布的一份报告指出，多伦多住宅建筑的天然气消耗量占其排放量的97%（多伦多市，2021年6月）。TransformTO净零战略中包含的净零技术模型的一个关键发现是，化石燃料，主要是家庭和建筑物中使用的天然气，需要在2040年前完全淘汰（多伦多市，2021年11月）。对于现有的住宅，这涉及到能源效率的显著提高。然而，绝大多数行业没有深度能源改造的经验（例如，目标是减少80-90%的能源消耗和相关排放）。此外，房主通常不知道或认为他们负担不起必要的措施。如果没有一个经过验证的例子项目在多伦多指出，PeelPHC的挑战是说服潜在的单户房主客户采用被动房改造。因此，目前正在进行的许多改造在减少温室气体方面的改进有限。为这种改造开发技术解决方案超出了典型房主的预算。 这笔赠款将提供急需的财政支持，以开发标准化的具有成本效益的解决方案，对单户住宅的被动式房屋进行改造。

Peel Passive House Consulting Ltd (PeelPHC) provides consulting services to developers, building owners and design professionals to help them achieve Passive House requirements for both new and existing buildings. Such projects result in substantial carbon savings, which represents the one of the main goals of many organizations across Canada.The City of Toronto's Greenhouse gas (GHG) emissions reductions targets demand substantial action on existing homes. A report published in June 2021 notes that natural gas consumption in Toronto's residential buildings represents 97% of their emissions (City of Toronto, June 2021). A key finding from the net zero technical modelling included in the TransformTO Net Zero Strategy is that fossil fuels, primarily natural gas used in homes and buildings, need to be completely phased out by 2040 (City of Toronto, November 2021). For existing homes, this involves a significant improvement of energy efficiency. However, the vast majority of the industry has no experience with deep energy retrofits (for example, targeting 80-90% reduction of energy consumption and associated emissions). Additionally, homeowners are generally either not aware of or believe they cannot afford the necessary measures. Without a verified example project in Toronto to point to, PeelPHC is challenged to convince prospective single-family homeowner clients to adopt Passive House for their retrofits. Therefore, many retrofits are being undertaken with limited GHG reduction improvements. Developing technical solutions for such a retrofit is beyond the budget of typical homeowners. This grant will provide much needed financial support to develop standardized cost-effective solutions to Passive House retrofits of single-family homes.
