The evaluation of the Victorian Healthy Homes Program (VHHP) will generate evidence about the efficacy and cost-effectiveness of home upgrades to improve thermal comfort, reduce energy use and produce health and economic benefits to vulnerable households in Victoria, Australia.
The VHHP evaluation will use a staggered, parallel group clustered randomised controlled trial to test the home energy intervention in 1000 households. All households will receive the intervention either before (intervention group) or after (control group) winter (defined as 22 June to 21 September). The trial spans three winters with differing numbers of households in each cohort. The primary outcome is the mean difference in indoor average daily temperature between intervention and control households during the winter period. Secondary outcomes include household energy consumption and residential energy efficiency, self-reported respiratory symptoms, health-related quality of life, healthcare utilisation, absences from school/work and self-reported conditions within the home. Linear and logistic regression will be used to analyse the primary and secondary outcomes, controlling for clustering of households by area and the possible confounders of year and timing of intervention, to compare the treatment and control groups over the winter period. Economic evaluation will include a cost-effectiveness and cost-benefit analysis.
Ethical approval was received from Victorian Department of Human Services Human Research Ethics Committee (reference number: 04/17), University of Technology Sydney Human Research Ethics Committee (reference number: ETH18-2273) and Australian Government Department of Veterans Affairs. Study results will be disseminated in a final report and peer-reviewed journals.

维多利亚健康家园计划（VHHP）的评估将为改善弱势群体家庭的热舒适度、减少能源使用并带来健康和经济效益的家庭升级措施的效果和成本效益提供证据，该计划位于澳大利亚维多利亚州。
VHHP 评估将使用交错的、平行组聚类随机对照试验来测试 1000 户家庭的家庭能源干预措施。所有家庭都将在冬季（定义为 6 月 22 日至 9 月 21 日）之前（干预组）或之后（对照组）接受干预。该试验跨越三个冬季，每个队列中的家庭数量不同。主要结果是冬季期间干预组和对照组家庭室内平均每日温度的平均差异。次要结果包括家庭能源消耗和住宅能源效率、自我报告的呼吸道症状、健康相关生活质量、医疗保健利用、学校/工作缺勤和家庭内自我报告的状况。线性和逻辑回归将用于分析主要和次要结果，控制家庭按区域聚类以及干预时间和年份的可能混杂因素，以在冬季期间比较治疗组和对照组。经济评估将包括成本效益和成本效益分析。
维多利亚州人类服务部人类研究伦理委员会（参考编号：04/17）、悉尼科技大学人类研究伦理委员会（参考编号：ETH18-2273）和澳大利亚政府退伍军人事务部已批准该研究。研究结果将在最终报告和同行评审期刊中公布。
