A prospective analysis of the employment impacts of energy efficiency retrofit investment in Portugal by 2020

Energy efficiency plays a significant role in increasing the security of energy supply and mitigating climate change. Although this role is indubitable, there is an ongoing discussion about the employment impacts of promoting energy efficiency measures, in particular of building retrofit investments. The purpose of this paper is to provide an estimation of the number of net jobs associated with the most common retrofit investment options in the building stock of Portugal. The examined investment options aim at improving the thermal properties of the building envelope and include the insulation of external walls and roof and the substitution of window frames and single glazed windows. The implementation of a methodological frameworkfor the assessment of employment benefits is based on Input-Output (I-O) analysis, providing consistent estimates for depicting the significant contribution of energy saving measures in the building sector (residential, private services and public services) in net employment generation.

能源效率在提升能源供应安全性与减缓气候变化方面发挥着关键作用。尽管这一作用毋庸置疑，但当前学界仍围绕推广能效措施——尤其是建筑改造投资——的就业影响持续展开讨论。本研究旨在估算葡萄牙建筑存量中，各类主流改造投资方案所关联的净就业岗位数量。本次考察的投资方案旨在优化建筑围护结构的热工性能，具体涵盖外墙与屋顶保温改造，以及窗框与单层玻璃窗的更换作业。本研究采用的就业效益评估方法论框架基于投入产出分析（Input-Output, I-O），可生成一致性的估算结果，用以阐明建筑行业（包括住宅、私人服务与公共服务领域）的节能措施对净就业创造的显著贡献。
