Existing buildings represent a significant energy saving potential in Europe, and retrofitting the building stock is essential to reach European targets. Retrofitting measures should reduce the energy consumption as well as improve the indoor climate while still being cost-effective. This can be challenging in European cold climates. This paper discusses energy performance requirements and challenges in the retrofitting process. It also presents an overview of the retrofitting status and relevant energy saving retrofitting measures with their potential for residential buildings. Measures to lower the building’s energy demand and electrical energy consumption and measures to control and monitor the energy use are discussed. Some research directions for the future of building energy usage are suggested. The literature indicates that significant energy savings can be achieved from retrofitting the building envelope. Relatively few research papers have been devoted to the energy saving potential of building control systems for existing residential buildings. However, these savings seem low compared to those that can be achieved through energy conservation. The actual savings from retrofitting the envelope, HVAC-systems and control systems are case specific and should be assessed for reference buildings of each housing typology.

欧洲寒冷气候下的节能住宅改造:回顾

现有建筑物在欧洲具有巨大的节能潜力,因此改造建筑物的库存对于达到欧洲目标至关重要。改造措施应在降低成本的同时降低能耗并改善室内气候。在欧洲寒冷的气候中,这可能是一个挑战。本文讨论了能源性能要求和改造过程中的挑战。它还概述了改造状态以及相关的节能改造措施及其在住宅建筑中的潜力。讨论了降低建筑物能源需求和电能消耗的措施,以及控制和监视能源使用的措施。提出了一些未来建筑能耗的研究方向。文献表明,通过改造建筑围护结构可以实现显着的节能。相对较少的研究论文致力于现有住宅建筑的建筑控制系统的节能潜力。但是,与通过节能实现的节省相比,这些节省似乎很少。改造围护结构,HVAC系统和控制系统所节省的实际成本取决于具体情况,应针对每种房屋类型的参考建筑物进行评估。
