“…We know little about what kind of requirements we will need for different types of buildings in the future, but the only thing we know is that if good living and social life are to be maintained, buildings and areas must be maintenance-friendly and adaptable to meet the new demands that we know will come (Kristl et al , 2019; Kristl et al , 2020).…”

Purpose Increasing focus on sustainability, in general, climate change impact, circular economy and a substantial need for CO2 footprint reduction within the construction industry, requires new knowledge and processes regarding the existing buildings. To satisfy new laws and regulations for new buildings is an easier challenge in comparison with possibilities in existing building stock which has the biggest contribution to sustainability within the construction industry. The purpose of the study is to develop and present a standardized process for sustainable refurbishment which, in addition to technical aspects, has a goal to create “well-being” for stakeholders, people organizations in private and public businesses and society itself. Design/methodology/approach The latest state of the art in the mentioned field has been assessed, and the developments along with potential future research focus have been identified. The process is presented in this paper, from the starting point of establishing the Norwegian standards in 1995 (NS 3454) until now, the development of the new CEN standard (prEN 17860:2022). The basic methodology designed for NS 3454 was improved through Nordic tools for indicator requirements SURE 1 (2011) and SURE 2 (2015). Further development of the tool was adopted by CEN TC 350 Sustainable Construction in 2017 with the aim to extend the good Nordic practices to the European level. In the paper, the design of the new standard prEN 17860:2022 is presented, from the process and content perspective, following the Nordic approach of standardized methodology and enhancing it with new dimensions and evaluation tools. Throughout the years, the standardized methodology, based on NS 3424, has been implemented in practical use for facility management in the Norwegian public sector. Positive experiences and feedback from this practical implementation have been taken into consideration in prEN 17680:2022. Findings The authors present the guidance, developed as a process, leading facility managers and other stakeholders through sustainable refurbishment standards and rules to make a clear decision about their concrete investment. The tool enables decisions about all three sustainability pillars and better decisions for health, well-being and quality of life. All the characteristics of the standardized methodology from the Nordic approach were supplemented (technical aspects; adaptability; usability; social aspects; energy, water and operational impacts and quality of indoor environment including health aspects) and some new were added (economic, feasibility, climate resilience and embodied environmental impacts). The tool also presents a building performance profile for further service life. Social implications Sustainable cities have been a focus for many years now from various perspectives such as SURE 1 or 2 and CEN TC 350. What these studies neglect is a clear and helpful guideline, supporting the FM, users and investors while deciding the operating and maintaining infrastructure in an urban environment. Better standardized forms give the possibility to make better climate-neutral choices and keep the well-being focus by choosing buildings with a potential for a long lifetime. Originality/value The new focus of addressing all stakeholders, including people, promoting sustainable refurbishment by informing, engaging and empowering them to take the decisions.

“…Another contributing factor is the adoption of existing sustainability assessment methods; BREEAM (by British Research Establishment) and LEED (by US Green Building Council) are both certification systems that evaluate and rate the sustainability performance of buildings which can be mainly intended or adapted for building renovation context [6]. Although professionals increasingly favor concrete climate change mitigation measures, the public favors adaptation processes only in general terms [7]. While these systems can help promote sustainable building practices, there are some potential areas for IOP Publishing doi:10.1088/1755-1315/1176/1/012041 2 improvement regarding public participation.…”

A sustainable refurbishment is an important approach toward reaching the EU’s climate goals. Some challenges of transforming housing areas are few high-quality standards, lack of funding, and low residential interest. This paper aims to present the process of establishing the Sustainable Accounting Standard (SAS) project, led by the Housing Federation of Norway (NBBL), representing 41 cooperative housing associations with 1,186,000 members. Therefore, a need to develop a standardized process for evaluating the possibilities of sustainable refurbishment is in focus. A triangulating combination of literature review, survey, and interview is chosen. The literature review forms a theoretical basis within the field. The design and experiences of SAS are reflected through interviews with project participants from cooperative housing associations and a survey of residential board members from selected pilot projects. The project presents the findings from developing the SAS tool and various stakeholders. The SAS tool forms an improved process for sustainable development in housing co-operatives, addressing all aspects of sustainability, the early involvement of stakeholders, and the importance of residents’ participation. The SAS contributes to a smoother refurbishment process by properly prioritizing improved measures.

“…These government endeavours, perceived as an ambitious target, are greeted with several challenges, including poverty and overpopulation (Abubakar, 2022). Additionally, (Kristl et al, 2020) emphasised that one of the challenges to climate change adaptation in the building sector is the need for more building policies and legislation governing buildings. A study conducted by (Allu, 2014) also opines that the lack of design guides and carbon emissions data in residential buildings in Nigeria is linked with the evidence of the negative impacts of climate change experienced.…”

“…Likewise, the depletion of natural resources and the lack of re-use in the construction industry are also some of the challenges threatening the future of humanity as far as climate change is concerned (Ahmed et al, 2021). The implications of this temperature rise have far-reaching consequences in the built environment and demand urgent interventions from key players in the industry, including the end users, whose lifestyles need to change for a better quality of life (Kristl et al, 2020). Most of the existing buildings today and currently designed ones will be rendered obsolete in terms of energy efficiency in the future (Escandón et al, 2019), except if a conscious attempt is made to consider their adaptability during their entire service lives (Kristl et al, 2020).…”

The predicted rise in global temperature by the Intergovernmental Panel on Climate Change IPCC appeals for a review of the methods and materials used for building construction for reduced emissions and comfort in buildings. Buildings account for the most carbon emissions in the globe. This study presents the impact of temperature change across the 36 state capitals in Nigeria, and the Federal Capital Territory, FCT, based on Representative Concentration Pathways, RCPs 4.5 for 2020 and 8.5 for 2090. A simple studio apartment with optimised alternatives for retrofits and new builds was simulated using EnergyPlus for both climate scenarios to determine the strategies for improving the energy performance of future buildings. The result of the study shows a significant increase in mean monthly outdoor temperature of about 5⁰c across the states, with potential heat stress affecting buildings in future climates. Moreover, about one-third of the locations experience a shift in climatic zones to hotter ones. The impact of this climate drift will be more severe in the Northcentral and Southwest regions of the country. The design strategies recommended to mitigate the effects of a changing climate focused on building envelope insulation, thermal mass, and solar shading. The performance of the optimised models under future scenarios accounts for up to 25% and 73% savings in cooling energy for retrofits and new builds, respectively. To protect existing buildings from the impact of future climates, developers must make massive investments in solar shading of buildings. In contrast, a combination of envelope insulation and solar shading strategies proves effective for new builds.
