近年来，英国家庭在提高能效方面的进展停滞不前，问题是，整个住房存量还有多少进一步节能的潜力。虽然有一些对英国建筑能效潜力的高水平估计，但需要进行更细粒度的评估，以确切地了解这种潜力在哪里以及采取什么形式。我们的分析填补了这一空白。它基于现有的最佳证据，表明英国住宅建筑内仍有提高能效的潜力。使用英国政府的投资评估标准，我们证明了英国家庭中有大量未开发的节能机会。具体地说，我们的估计表明：到2035年，英国家庭目前使用的能源中有四分之一可以以成本效益的方式节省下来；如果考虑到技术成本的下降和能源效率提高带来的更广泛的好处，这一比例可能会增加到一半。然而，这些估计对关于资本、能源和碳成本的假设很敏感，要抓住这种潜力，既需要重大的政策变化，也需要大规模投资。
Progress on improving energy efficiency of UK homes has stalled in recent years and the question arises how much more potential for further energy savings exist across the housing stock. Whilst there are some high-level estimates of the potential for buildings energy efficiency in the UK, a more granular assessment is needed to understand exactly where this potential lies and what form it takes. Our analysis fills this gap. It is based on the best available evidence on the remaining potential for energy efficiency improvements within UK residential buildings. Using UK government criteria for investment appraisal, we demonstrate that there is a significant resource of untapped energy-saving opportunities in UK homes. Specifically, our estimates suggest that: one quarter of the energy currently used in UK households could be cost effectively saved by 2035; and this could increase to one half if allowance is made for falling technology costs and the wider benefits of energy efficiency improvements. However, these estimates are sensitive to the assumptions made about capital, energy and carbon costs, and capturing this potential will require both significant policy change and large-scale investment.
