“…Sustainable renovation has the potential to improve the energy performance of buildings and decreased costs for operation and maintenance, but also the housing situation and wellbeing of people with respect to indoor-climate and comfort [14], improved accessibility for elderly [15,16] and to mitigate energy poverty [17]. However, the implementation of sustainable renovation has met challenges in practice and has often led to conflicts between property owners and tenants [18,19].…”

An important part of the multi-family housing stock in Sweden was built during the record years 1961–1975 and is in need of extensive renovation to be modernized. The stock is also at the center of political discussion of how to sustain ‘good housing for all’, especially in the rental sector. These renovation needs coincide with present energy targets and provides an opportunity to combine renovation with energy efficiency measures. Common for many of these buildings are that neglected maintenance has led to technical shortcomings, such as high energy use and low thermal comfort due to bad insulation, unsatisfactory air tightness and leaky windows, inefficient heating systems and insufficient ventilation, and moisture damage due to leaking building envelope and leaking pipes. However, the people living in these buildings are not willing to or cannot afford to pay the higher rents that extensive renovations would entail. Earlier research has highlighted the broader societal problem of energy renovations, but also that of housing companies’ priority of measures with short payback times, and those that give the possibility to raise rents. However, recent observations indicated a tendency towards more holistic approaches to housing renovation, and this study was initiated to investigate how public and private housing companies deal with renovation levels, rent increases and related social problems. The main conclusions are that sustainability and social responsibility are moving up on agendas in the public sector, but also, apparently, in the renovations strategies among the private companies. What is also seen is a trend moving from extensive total renovations to more tenant-adapted and step-by-step renovations. Renovation options which do not entail such large rent increases are increasingly being seen. Implications are that housing owners favor gentle renovation with reasonable rent increases of 10%–20%, which at the same time, may be a drawback for reaching energy efficiency targets.

“…In addition, authors concluded that the passive house performs only slightly better in terms of environmental impacts, with respect to a reference case. The same research group also presented an overview of the strategies for the renovation of building stock for ageing society [163] and a life cycle optimization tools for building early design phases [164]. Gourlis et al [159] analyzed passive measures for preventing summer overheating in industrial buildings.…”

EU energy policy is more and more promoting a resilient, efficient and sustainable energy system. Several agreements have been signed in the last few months that set ambitious goals in terms of energy efficiency and emission reductions and to reduce the energy consumption in buildings. These actions are expected to fulfill the goals negotiated at the Paris Agreement in 2015. The successful development of this ambitious energy policy needs to be supported by scientific knowledge: a huge effort must be made in order to develop more efficient energy conversion technologies based both on renewables and fossil fuels. Similarly, researchers are also expected to work on the integration of conventional and novel systems, also taking into account the needs for the management of the novel energy systems in terms of energy storage and devices management. Therefore, a multi-disciplinary approach is required in order to achieve these goals. To ensure that the scientists belonging to the different disciplines are aware of the scientific progress in the other research areas, specific Conferences are periodically organized. One of the most popular conferences in this area is the Sustainable Development of Energy, Water and Environment Systems (SDEWES) Series Conference. The 12th Sustainable Development of Energy, Water and Environment Systems Conference was recently held in Dubrovnik, Croatia. The present Special Issue of Energies, specifically dedicated to the 12th SDEWES Conference, is focused on five main fields: energy policy and energy efficiency in smart energy systems, polygeneration and district heating, advanced combustion techniques and fuels, biomass and building efficiency.

“…In terms of scale, we observe that a majority of applications of the methodology have been at the building or component scale, especially to compare different constructive solutions and construction materials or to optimize the insulation thicknesses of the building envelope [8,12,32,33,[37][38][39][40][41][42]. When at the building scale, studies typically consider only one specific typology for a given period of time or year (e.g.…”

As tomorrow's cities are already largely built, many strategies stress the importance of urban renewal processes to address current energy issues. This paper focuses on the Spanish residential building stock built until 2001, which has a low level of energy performance.Considering the current economic crisis, the future lies in renovating the built environment, which holds a significant energy-saving potential. This potential is here quantified by applying the cost-optimal methodology, initially proposed by the Energy Performance of Buildings Directive, and which calculates costoptimal levels of minimum energy performance requirements at the building and component scale.The originality of our study lies in the application of this methodology at the territorial scale, comparing different retrofitting scenarios by scaling-up building-scale results through an archetypal approach. We also describe an Excel-based tool allowing two types of studies: (i) at the building scale, for one archetype in a particular climatic zone; (ii) at the territorial scale, to have an overview of all building archetypes and climatic zones simultaneously. Results include economic aspects, energy consumption and savings and associated emissions.The outcome can help construction-sector firms adapt their business plan, while also providing stakeholders with decision-support to promote a sustainable renewal of the building stock.
