The building sector is a large energy consumer and is responsible for high CO₂ emissions; hence, improving the energy performance of buildings is vital. Building renovations open opportunities to improve their energy performance.

Building professionals and other actors in the early phase of renovations decide what energy efficiency and saving measures will be implemented. Their role is studied here from a middle-out perspective (MOP), investigating the different actors’ agency and capacity. Agency refers here to an interest in and a willingness to implement energy efficiency and saving measures, and capacity refers to the ability to implement such measures. Higher agency and capacity are said to increase the realisation of the planned energy efficiency and saving measures.

The data was gathered during three planning and design phases of renovation projects of a municipal housing company in a middle-sized Swedish town. A case study was conducted which is based on semi-structured interviews with actors from the planning and design phase of the renovations, as well as participant observations and a document analysis.

The levels of agency and capacity of professionals in the middle of a project’s planning and design phase are investigated thoroughly, but the here defined top and bottom levels are also in focus. The analysis shows that a mismatch in agency and capacity on the different levels hindered the uptake of energy efficiency and saving measures in the planning and design of the renovation projects.

建筑部门是一个巨大的能源消耗者，并导致大量的CO ₂排放。因此，改善建筑物的能源性能至关重要。建筑翻新为改善其能源绩效提供了机会。

在装修的早期阶段，建筑专业人士和其他参与者决定将执行哪些能源效率和节能措施。在这里，我们将从中间派（MOP）角度研究他们的角色，调查不同参与者的代理和能力。在这里，代理是指对实施节能和节能措施的兴趣和意愿，能力是指实施此类措施的能力。据说更高的机构和能力可以增加计划能源效率和节能措施的实现。

数据是在瑞典中型城镇的一家市政房屋公司的翻新项目的三个计划和设计阶段中收集的。进行了一个案例研究，该研究基于整修计划和设计阶段对演员的半结构化访谈，以及参与者的观察和文档分析。

在项目的规划和设计阶段的中间，对代理机构和专业人员的能力水平进行了彻底调查，但是这里定义的最高和最低水平也是重点。分析表明，各级机构和能力的不匹配阻碍了在翻新项目的规划和设计中采用能源效率和节能措施。
