Renovation at district scale is a key strategy to reduce CO 2 emissions by optimising the implementation of renewable energy sources and taking advantage of economy of scale. This paper focuses on analysing good practice examples on energy renovations at district scale. The paper adapts a qualitative research methodology in four phases, including the multi-perspective analysis of nine exemplary renovation projects in six European countries, including identification of drivers and barriers of different stakeholders.It is found that the drivers for a district renovation are not restricted to energy savings, but typically also include improving the overall quality of life as well as the image and economic value of a district. Moreover, the need for financial models that can alleviate split-incentive problems between investors and resident organizations is identified.Barriers for carrying out a district renovation include that there is a need to comply with energy standards, that the renovation scope had to be limited to avoid a noticeable rent increase and that resettling of tenants during the renovation is often not possible.Lessons learned include that good communication amongst the different stakeholders, especially with residents, plays a key role for the success of the project. Furthermore, a strong leadership is needed to coordinate activities due to the great number of stakeholders.

“…Within the Annex, a methodology is developed for assessing the most costeffective balance between energy efficiency measures and measures on the energy supply system. Terés-Zubiaga et al [5] present the key elements of the methodology and show how it can be successfully applied at a Portuguese district. An extensive description is to be published at the Annex 75 website [6].…”

Cost optimal investment in energy efficiency measures and energy supply system in a neighbourhood in Norway

et al. 2021

Building renovation is a key measure to reduce energy consumption and Greenhouse gas (GHG) emissions, and ease the transition to a fully renewable energy system. This paper applies the IEA EBC Annex 75 methodology for investigating the cost optimal and environmental trade-off between investment in energy efficiency measures on the building envelope and energy supply, on a residential neighbourhood in Norway. Combination of different energy efficiency measures and energy supply systems are investigated with an optimal investment model. The cost and environmental impact of the combinations are evaluated. An important outcome is that within the evaluated combinations, the choice of energy supply system has little impact on the cost effectiveness of the energy efficiency measures. However, it has a significant impact on the GHG emissions. The results also highlight the importance of performing energy efficiency measures in coordination with other renovating measures, both regarding cost effectiveness and environmental impact. The results will not give a finite answer to what is the best solution but serves at a useful set of inputs for overall evaluations.

“…Future research should focus on providing more detailed LCA case studies that would allow the creation of databases similar to energy performance certificate databases available in some countries and regions referenced in [18]. This would allow the creation of guidelines and recommendations that are more accurate than those currently available as deliverables of projects such as ALDREN or Annex 56 [12,13]. Such guidelines would be beneficial for any practitioner dealing with the design and assessment of an efficient building with minimal impact on the environment.…”

“…The problem is the application of these solutions in existing buildings. There are recent projects such as IEA EBC (International Energy Agency's Energy in Buildings and Communities Programme) Annex 56, Annex 75, or ALDREN that both promote and provide guidelines for "deep" renovations [11][12][13]. Still, the average age of a European building is 55 years and only approximately 1% of them undergo renovation each year, according to [14,15].…”

Life-Cycle Assessment of a Rural Terraced House: A Struggle with Sustainability of Building Renovations

Contemporary research stresses the need to reduce mankind’s environmental impacts and achieve sustainability. One of the keys to this is the construction sector. New buildings have to comply with strict limits regarding resource consumption (energy, water use, etc.). However, they make up only a fraction of the existing building stock. Renovations of existing buildings are therefore essential for the reduction of the environmental impacts in the construction sector. This paper illustrates the situation using a case study of a rural terraced house in a village near Brno, Czech Republic. It compares the life-cycle assessment (LCA) of the original house and its proposed renovation as well as demolition followed by new construction. The LCA covers both the initial embodied environmental impacts (EEIs) and the 60-year operation of the house with several variants of energy sources. The results show that the proposed renovation would reduce overall environmental impacts (OEIs) of the house by up to 90% and the demolition and new construction by up to 93% depending on the selected energy sources. As such, the results confirm the importance of renovations and the installation of environmentally-friendly energy sources for achieving sustainability in the construction sector. They also show the desirability of the replacement of inefficient old buildings by new construction in specific cases.
