Equitable portfolio upgrades for demand reduction (EPURE) tool

建筑环境每年占英国温室气体排放总量的25%，这正在缓慢降低投资组合的净零目标。迫切需要关注的是，房主、房东、社会住房、私营部门商业、学校和公共资产能够更迅速、更公正地过渡到脱碳途径。EPURE解决方案概念提出了一种工具，将最好的数据源与升级干预解决方案、居住者需求和供应链能力相结合，用于组合级别的建筑表征。它将开发和测试一个可扩展的商业服务提案，使用户能够确定短期，中期和长期的升级组合，以减少需求（减少排放和占用费用）。这种数据驱动的方法来评估和定义升级建筑组合的适当途径，将提供实用的脱碳选择，并有助于为提供建筑改进的供应链建立市场确定性。我们选择与赫特福德郡理事会合作作为主要用户，并召集了广泛的利益相关者（例如，建筑组合所有者、供应链组织、金融机构、代表居住者/用户的团体），以帮助塑造概念。EPURE解决方案概念是一种建筑组合优化工具，它使用来自BRE的独特数据（英国范围的住房数据，以提供条件和性能洞察并识别燃料贫困的家庭）与开放访问数据源（例如，OpenEPC，供应链基础设施）和目标用户数据（例如，赫特福德郡理事会建筑物），以确定最佳的方法来升级现有的建筑物。概念解决方案使用建筑原型（类型、年龄、位置、结构）结合特定居住者需求，升级技术以及地方和国家供应链的范围和能力。数据源的组合使我们能够确定从升级中受益最多的公共建筑以及燃料贫困的家庭或需要获得支持的社区中更脆弱成员的家庭。升级解决方案概念成功的关键在于它不会“留下建筑物”或仅适用于社会的特定部分。我们与当地慈善机构和住房协会以及技术解决方案供应链的利益相关者进行了合作。BRE是一家独立、公正、以研究为基础的咨询公司，提供建筑环境和相关行业各个方面的专业知识。我们值得信赖和独立的标准和产品使我们能够有力地开发和部署EPURE，构建第2阶段之后的业务/投资案例。

The built environment contributes 25% of total UK GHG emissions per annum which is slowly reducing threatening net zero ambitions for portfolios. Urgent attention is needed to enable a more rapid and just transition to decarbonisation pathways by homeowners, landlords, social housing, private sector commercial, schools and public assets. The EPURE solution concept proposes a tool combining the best possible data sources for building characterisation at portfolio level, with upgrade intervention solutions, occupant needs and supply chain capacity to deliver. It will develop and test a scalable commercial service proposition to enable users to identify short-, medium- and longer-term upgrades to portfolios to reduce demand (reduced emissions and occupant bills). This data driven approach to assessing and defining appropriate pathways for upgrading building portfolios will provide practical decarbonisation options and contribute to building market certainty for supply chains delivering building improvements.We have selected to work with Hertfordshire County Council as the primary user and have assembled a wide range of stakeholders (e.g., building portfolio owners, supply chain organisations, financial institutions, groups representing occupants/users) to help shape the concept. The EPURE solution concept is a building portfolio optioneering tool that uses unique data from BRE (UK wide housing data to provide condition and performance insight and identify households in fuel poverty) combined with open-access data sources (e.g., OpenEPC, supply chain infrastructure) and target users data (e.g., Hertfordshire County Council buildings) to identify best approaches to upgrading existing buildings. The concept solution uses building archetypes (type, age, location, construction) combined with specific occupant needs, upgrade technologies and the extent and capacity of local and national supply chains to deliver.The combination of data sources provides us with the ability to identify public buildings most benefiting from upgrade as well as households in fuel poverty or those with more vulnerable members of the community that need support accessing upgrade. Critical to the success of the solution concept is that it doesn't 'leave buildings behind' or only work for a specific section of society. We have included in our stakeholder engagement local charities and housing associations to help with this as well as the supply chain for technical solutions.BRE is an independent and impartial, research-based consultancy, offering expertise in every aspect of the built environment and associated industries. Our trusted and independent standards and products positions us strongly to develop and deploy EPURE building the business/investment case beyond Phase 2\.
