Any building refurbishment is challenging and school buildings offer no exception. They are increasingly in need of refurbishment due to their age and evolving teaching and learning. The purpose of this paper is to present an overview of literature on sustainable refurbishment so as to identify key lessons from selected successful refurbishment projects. The review findings are expected to contribute to the development of refurbishment plans in an effective and innovative manner that should extend building’s service life, focus on resource efficiency, and comfort their users. It will also contribute to knowledge base of refurbishment and suggest future directions for research.

The paper has undertaken a literature review on the sustainability assessment of buildings and frameworks for sustainable refurbishment. Besides, the work also provides a review of recent successful refurbishment projects to collect and structure systems experiences which can be adopted in developing a sustainable refurbishment strategy for school buildings.

Findings include three groups of lessons in terms of reasons, process and barriers in the selected refurbishment projects that assist stakeholders to prepare a suitable refurbishment plan for their school buildings. The potential of 3D scanners and BIM applications in the refurbishment process will also be reviewed in order to develop a proposed framework of 3D scanner vs BIM for the refurbishment process. Recommendations highlight the role of a national strategy as a driving factor for applying the advantages of information technology to enhance optimal solution selection processes to get better and more sustainable results.

The conceptual framework for 3D scanner and BIM applications within sustainable refurbishment for school buildings is currently under researched, and the findings aimed to address such a gap when considering 3D scanners and BIM applications in the refurbishment process.

The first paper, entitled “The perception of tenants in the refurbishment of tower blocks” (Facilities, Vol. 31, No. 3/4), argued that refurbishment was the best option that a local authority could undertake to improve tower blocks. The study also found that refurbishment maintained local communities by keeping families together and sustained the environment. This paper aims to present and examine similar views from the contractor's and landlord's representatives on several aspects affecting the refurbishment process

A literature review is used to identify the perceived problems and benefits of refurbishment. A qualitative approach comprising semi structured interviews and questionnaires was used to collect data from three contractors or service providers of the refurbishment process and two landlords' representatives, namely the clerk of works drawn from the housing association. The sample data are analysed using frequency analysis and content analysis.

Refurbishment as opposed to demolition was identified as a viable option for achieving sustainability. There were some divergent views among the respondents concerning the achievements to be gained from refurbishments. The project managers identified “client satisfaction”, and “within budget and time”. The senior site manager chose “a better way of life” and “improved security”. The quantity surveyor opted for “profit‐oriented”, finally, “provision of decent homes at affordable prices” was identified by the senior clerk of works. The knowledge of the council funding mechanisms for refurbishment works among the respondents ranged from adequate to ideal. The contractor's representatives exhibited limited knowledge.

The findings of the study provide practical value for contractor's and landlord's (housing association) representatives within the construction industry confronted with the decision of whether to undertake some refurbishment works. Some lessons learned could also improve the housing stock or asset management strategies for the landlord's representatives.

The paper is original in the sense that it identifies how the contractor's and landlord's (housing association) representatives as drawn from different professional background rate the reasons, benefits, and practicalities of undertaking refurbishment works of tower blocks or high rise buildings. The study also provides some insights on the contractor's and landlord's (housing association) representative's knowledge and awareness of sustainable development, and councils' funding mechanisms for undertaking refurbishment works.

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.

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.

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.

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.

The new focus of addressing all stakeholders, including people, promoting sustainable refurbishment by informing, engaging and empowering them to take the decisions.

The aim of this review article is to identify a number of key research efforts related to decision making tools in building refurbishment projects and selected energy efficiency efforts in the built environment. Following these findings a proposed research area with focus on energy in the building environment will be suggested for further investigation.

Through a multilateral review study, a number of major research efforts in sustainable refurbishment are highlighted. The necessity of directing future research towards energy conservation is illustrated for a specific approach to developing the built environment.

The findings of this article identify high performance thermal insulation solutions as one of the promising approaches to significant energy consumption reductions in buildings.

This review study is solely limited to the revisited research directions.

This study successfully identifies a number of decision making tools related to building refurbishment and an initial research path in favor of building energy consumption reductions.

The purpose of this paper is to draw attention to some of the practical difficulties that exist within the current regulatory framework that is guiding refurbishment practice with regard to improving energy efficiency and reducing carbon emissions.

The paper presents a critical review of Building Regulations Approved Document L2B, the current models for measuring energy and carbon emissions and third‐party certification schemes.

Sustainable refurbishment programmes can incorporate various measures and technologies to help to address the current efficiency and emission targets. Yet while specific improvements to energy efficiency and carbon emission may be technically possible, it seems that they are unnecessarily hampered by a series of hurdles.

The paper offers a detailed and applied consideration of three regulatory issues that can affect the achievement of sustainable measure targets in sustainable refurbishment projects.

Abandonment poses a range of effects detrimental to the development of a country such as Nigeria. Restoring such infrastructure in a sustainable manner is a challenge identified in the literature. The aim of this study is to evaluate a novel approach – the technique for order preference by similarity to an ideal solution (TOPSIS) to identify the sustainability criteria for the redevelopment of abandoned infrastructure in Nigeria. The literature evidences use of TOPSIS in various development contexts, but not in the context of redevelopment of abandoned infrastructure.

This study explores the potential of TOPSIS in the sustainable redevelopment of abandoned infrastructure in Nigeria through a combination of a quantitative method of data collection – questionnaire – and a case study. The case study focuses on the abandoned Federal Government Secretariat in Lagos. One hundred and sixty-one (161) participants responded to the questionnaire. Data collected were analyzed using TOPSIS analytical technique.

Refurbishment is considered as the most sustainable alternative for the redevelopment of abandoned infrastructure. For criteria consideration, structural integrity and foundation categorized under the technological attributes ranked highest for refurbishment and conversion alternatives. Waste generation and prevention and profitability top the list for demolition and procurement respectively.

The social benefit of this study is to bring building considered to be an eyesore back into use.

The findings from the analysis orchestrates the importance of the built environment research concentrating on innovative frameworks for sustainable redevelopment of abandoned structures in the construction industry.

The purpose of this paper is to show three principal aims – to highlight the gap in the international energy efficiency and carbon emission targets in relation to existing commercial real estate; to examine the contribution that such legacy stock could make to the various targets; and to provide commentary on some of the measures that are being introduced to support sustainable refurbishment in the legacy stock.

The paper critically reviews recent academic, policy and practitioner publications.

The international sustainability agenda is being driven through via a “top‐down” approach. Targets are largely concentrated on new‐build provision and there is a limited focus on existing stock. The annual rate of replacement of commercial sector stock is minimal. Unless the existing commercial stock is addressed in a meaningful way, other measures used to address anthropogenic climate change will be undermined.

The paper offers an applied examination of the potential of the existing stock of commercial real estate to contribute toward achieving targeted energy efficiency and carbon dioxide reduction targets.

The development of sustainable facilities management (FM) practices requires active and integrated engagement of the FM organization. Building on a three-year research project (2015-2018) within Nordic Built that aims to strengthen FM competencies in the Scandinavian countries, this paper aims to list and document the challenges and barriers of implementing sustainability as identified by the Scandinavian FM practitioners who took part in this research.

The paper builds on the understanding gained from using an interpretive sociological approach and uses qualitative mixed methods to collect data from four workshops, group sessions and expert group discussions with a mix of representatives including owners, property managers, facilities managers, consultants, teachers and academics. Four case studies were completed of refurbishment projects implementing sustainable solutions; these encompassed in-depth interviews with the stakeholders, site visits, observations of meetings and gathering project documentation. The data were complemented by a systematic literature review on a selection of topics focusing on articles referring directly to FM, the sustainability of FM, ends-user and stakeholder involvement, energy performance and sustainability. The challenges and barriers identified in practice were compared to those found in the literature.

The concept of sustainability, and its different dimensions and implications, seems to be well understood now by the practitioners who participated in this study, who claimed they were able to provide the required solutions. What seems to be lacking, though, is the possibility of convincing the end-users, who are expected to operate and maintain the facilities, to act according to the standards that these solutions require. It appears to be easier to focus on the technical aspects than on the end-users’ behaviors. The practitioners reported a shortage of social competencies and tools to deal with the situation, and despite an increasing awareness of smart technology, they lacked solutions to engage the end-users in optimizing the facilities. Besides, not all FM companies were well equipped to face the challenges imposed by the sustainable agenda; the small and medium enterprises in particular seemed to be struggling to implement the different dimensions of sustainability.

The limitation of this research rests in the chosen research approach as it focuses on the FM practitioners. The contribution of the end-users’ perspective is not strongly represented or systematically explored, but is identified as a new topic that needs to be investigated further to provide further insight. This study focuses on refurbishment and/or retrofit of existing buildings and the operation of facilities. The authors do not embrace the design phase or the construction phase of new buildings.

The paper underlines the need for frameworks and concrete tools to help FM practitioners to integrate the social and cultural aspects of sustainability. It identifies end-users, both in housing and in offices, as creating a bottleneck to the implementation of sustainable FM. To gain insight into this bottleneck, the authors suggest implementing a sociologically inspired method using an integrative approach. Highlighting such issues will mean that future research will be able to define further solutions for managing and maintaining existing and future built assets and fulfilling sustainability requirements by engaging end-users. This study also emphasizes the need to introduce these topics as part of the curriculum for FM education.

This paper provides an update on the level of the development of sustainable FM in the three Scandinavian countries. This is highly relevant for Scandinavian practitioners, but the authors consider this relevant for international practitioners, researchers, academics and teachers and developers as well. Practitioners and researchers are invited to join in these efforts to explore how to find practical frameworks, tools, policies and instruments and new services that will improve sustainable FM practices.

The purpose of this paper is to establish how UK offices and double skin façade (DSF) technologies can be best matched for refurbishment purposes.

This research uses a mixed methodology including primary and secondary data collection, analysis and interpolation through document analysis, comprehensive critical literature review, and case study approach.

In total, 22 benchmarks have been developed to represent 75 per cent of the existing office stock in the UK. Through a comparison with 36 case studies of European buildings refurbished with DSFs, two benchmarks showed to be most suitable for a DSF refurbishment and most appropriate configurations for a successful DSF refurbishment have been identified. Findings have been also checked against a large sample of DSF buildings in the UK.

The benchmarks delivered in this study can be developed further into parametric models, where variations can be obtained by changing the parameters provided. A follow-up study can be designed to help define the exact share of existing stock represented by each benchmark and to foster research where a more typological or statistical approach might be intended.

Findings from this research can be of practical use to academics and practitioners alike involved in research related to office refurbishments, DSFs, and the UK existing office stock. The design for this research can also be adapted to similar studies on its own or further developed to suit different contexts.

Improvements to existing buildings can preserve established communities, with a clear social advantage.

This paper represents the first attempt to systemically shed light on how existing UK offices and DSF technologies can be best matched in refurbishments. The benchmarks developed, the DSF case studies, and guidelines for suitable DSF technologies in UK office refurbishments represent the original contribution of this research.

Refurbishing houses is considered a key measure to improve the energy efficiency of the built environment. However, little is known about the implementation and outcome of housing renovation for energy upgrades in the Vietnamese practice. The purpose of this paper is to investigate the energy performance of the current housing stock in Vietnam and the potential to reduce energy use in households.

The paper is based on a survey with 153 respondents in three major climatic regions of Vietnam. The survey focusses on building characteristics, environmental performance, energy performance and refurbishment activities. Data collected from the survey were statistically analysed to give insight into the current performance of the housing stock and its energy saving potential.

This paper concludes that building design and construction, particularly the building envelope, have a significant influence on the occupants’ comfort. However, the energy consumption in houses is not statistically associated with building design and indoor environment. It is suggested that financial status and occupants’ behaviour currently have a strong influence on the household energy use. The survey also showed that refurbishment improves the housing performance, especially if improving the indoor environment was one of the drivers.

There are very few studies on energy use in households in Vietnam, especially with regards to actual energy consumption. This paper brings insights into the actual energy consumption and reveals the “performance gap” in Vietnamese housing stock.
