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

皮尔被动式房屋咨询有限公司(PeelPHC)为开发商、建筑物业主和设计专业人士提供咨询服务，帮助他们达到新建和现有建筑的被动式房屋要求。这样的项目可以大幅节省碳排放，这是加拿大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住宅采取实质性行动。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%(多伦多市政府，2021年6月)。转型为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，主要是用于家庭和建筑的天然气，需要在2040年完全淘汰(多伦多市，2021年11月)。对于现有的家庭来说，这涉及到能源效率的显著提高。然而，该行业的绝大多数人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，房主通常要么没有意识到，要么认为他们负担不起必要的措施。在多伦多没有一个经过验证的项目可供参考的情况下，PeelPHC面临着说服潜在的单一家庭房主客户采用被动式房屋进行翻新的挑战。因此，许多改装正在进行，但温室气体减排的改善有限。为这样的改造开发技术解决方案超出了一般房主的预算。这笔赠款将提供急需的财政支持，为独户住宅的被动式房屋翻新开发标准化的成本效益解决方案。

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.
