This document presents BasES, which is a tool kit disseminated as an open educational resource. BasES is focused on the topic of buildings-as-energy services, promoting the knowledge integration to envisage buildings as components of future distributed renewable and interactive energy systems (DRIs). BasES will allow users of exploring and analysing DRIs' emergent properties at the local level, developing, and implementing the tool kit proposed. The specific objective concerns the use of the tool kit in the organisation of a technology support net (TSN) for buildings-as-a-service. TSN is composed of a multitude of actors, who often have different perspectives and scopes, but they are called to work collaboratively in order to establish work rules, requisite skills, work contents, standards and measures, culture and organisational patterns with regard to the emergent systems. Buildings-as-a-service is a completely new topic, and thus, an appropriate TSN is needed urgently. Our tool kit (i.e. Buildings-as-Energy-Services; BasES) will be a ground-breaking cognitive apparatus for involving stakeholders in knowledge transfer and integration processes. Thus, a new generation of product-service systems will be promoted. BasES is expected to configure a multi-stakeholder co-designed UK roadmap on socio-technical innovation in DRIs transition.

Adaptability is an inherent quality in building circularity, as adaptability can physically facilitate the reversibility of materials in a closed-reversible chain, also called “loops”. Nevertheless, positioning adaptability in circularity-oriented models could overlook some of the contextual considerations that contribute to the utility for the built environment. This paper reconceptualises building adaptability to incorporate circularity, in order to facilitate for the resource loops whilst preserving the long-lasting functionality in buildings.

An integrative literature review on adaptability and circularity of buildings was conducted using systematic search approach. From the initial database of 4631 publications, 104 publications were included for the final analysis. A comparative analysis of definitions and determinants of both concepts was conducted to reconceptualise circular building adaptability.

The findings of the literature study show that incorporating circularity and adaptability is possible through 10 design and operation determinants, namely configuration flexibility, product dismantlability, asset multi-usability, design regularity, functional convertibility, material reversibility, building maintainability, resource recovery, volume scalability, and asset refit-ability. The study concludes that considering the defined determinants in a holistic manner could simultaneously facilitate: building resilience to contextual changes, creation of asset value, and elimination of waste generation.

This paper expands the relevant bodies of literature by providing a novel way of perceiving building adaptability, incorporating circularity. The practical value of this paper lies in the discussion of potential strategies that can be proactively or reactively employed to operationalise circular building adaptability.

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

The application of circular building adaptability (CBA) in adaptive reuse becomes an effective action for resource efficiency, long-lasting usability of the built environment and the sped-up transition to a circular economy (CE). This paper aims to explore to which extent CBA-related strategies are applied in adaptive reuse projects, considering enablers and obstacles.

A stepwise theory-practice-oriented approach was followed. Multiple-case studies of five circular adaptive reuse projects in The Netherlands were investigated, using archival research and in-depth interviews. A cross-case analysis of the findings was deductively conducted, to find and replicate common patterns.

The study revealed that configuration flexibility, product dismantlability and material reversibility were applied across the case studies, whereas functional convertibility and building maintainability were less applied. Low cost of material reuse, collaboration among team members and organisational motivation were frequently observed enabling factors. Lack of information, technical complexities, lack of circularity expertise and infeasibility of innovative circular solutions were frequently observed obstacles to applying CBA.

This paper provides practitioners with a set of CBA strategies that have been applied in the real world, facilitating the application of CBA in future adaptive reuse projects. Moreover, this set of strategies provides policymakers with tools for developing supportive regulations or amending existing regulations for facilitating CE through adaptive reuse.

This study provides empirical evidence on the application of CBA in different real-life contexts. It provides scholars and practitioners with a starting point for further developing guiding or decision-making tools for CBA in adaptive reuse.

Over the years, the significance of retrofitting has gained much attention with the unveiling of its different applications, such as energy retrofit and deep retrofit, to enhance the climate-resilience of buildings. However, no single study comprehensively assesses the climate-resilience of retrofitting. The purpose of this study is to address this gap via a systematic literature review.

Quality journal studies were selected using the PRISMA method and analysed manually and using scientometrics. Three dimensions of climate-resilience, such as robustness, withstanding and recovery, were used to evaluate the contribution of retrofit measures for achieving climate-resilient houses across four climate zones: tropical, arid, temperate and cold.

Most passive measures can enhance the robustness of residential buildings but cannot verify for withstanding against immediate shocks and timely recovery. However, some passive measures, such as night-time ventilation, show excellent performance over all four climate zones. Active measures such as heating, ventilation and air conditioning and mechanical ventilation with heat recovery, can ensure climate-resilience in all three dimensions in the short-term but contribute to greenhouse gas emissions, further exacerbating the long-term climate. Integrating renewable energy sources can defeat this issue. Thus, all three retrofit strategies should appropriately be adopted together to achieve climate-resilient houses.

Since the research is limited to secondary data, retrofit measures recommended in this research should be further investigated before application.

This review contributes to the knowledge domain of retrofitting by assessing the contribution of different retrofit measures to climate-resilience.

This paper aims to assess a measurement model of green cleaning for green buildings in Malaysia. Being one of the contributors to the indoor environmental quality performance, green cleaning has become one of the significant aspects that need to be considered for the well-being and performance of a building, particularly in a green building's operations and maintenance performance. Green buildings without green cleaning practices would hinder the benefits that should be rendered economically, socially and environmentally. However, the absence of clear green cleaning components and requirements in Malaysia has become a motivation to undertake this research.

A questionnaire survey involving cleaning service providers and green building index (GBI) facilitators was carried out, and the data was then analyzed using partial least squares structural equation modeling. However, this paper will only be focusing on the measurement model assessment.

Most of the green cleaning components and requirements are acceptable in the model except integrated pest management (in the cleaning procedure component) and hand soaps (in the product and materials component) due to lower factor loadings. Therefore, these two requirements were removed from the measurement model.

Due to a paucity of professionals in the field of green cleaning, the researchers have selected GBI facilitators and cleaning service providers as respondents for this research. The researchers assumed that GBI facilitators are aware of acceptable products and materials for green buildings; meanwhile, cleaning service providers know what is the best cleaning technique and process that helps in achieving cost and resource efficiency. This research also assumed that the green cleaning components identified can be applied to any type of green building, regardless of the differences in needs in each type of building.

This discovery will give the industry, particularly cleaning service providers and green building management teams, a first look at the green cleaning components and requirements.

This paper fulfills the need to study how green cleaning helps in achieving the benefits rendered by green buildings.

The adaptation of emerging building designs for single room occupancy in off-campus university student housing during the COVID-19 pandemic is evolving. However, assessing its effects on student satisfaction to compensate for COVID-19-associated impacts is missing. As a result, the study examines the satisfaction of students with emerging building designs in single-room off-campus student housing in Ghana.

The study is quantitatively based on positivist philosophical thinking. A purposive sample of 202 purpose-built student housing facilities was selected across public and private universities in Ghana. Using systematic stratified sampling, the study sampled 1,212 student residents through a survey. A principal component method (PCM) was used to assess the availability of 10 emerging building design and basic building services variables across the study location. Multiple regression was employed to determine the satisfaction and predict potential variables for policy formulation.

The analysis revealed that private space for social distancing, the availability of hands-free fittings in the toilet and bathroom, and the availability of hands-free fixtures in the kitchen unit was common single-room self-occupancy support systems. However, there is a huge gap in the availability of key emerging building designs and basic building services and their associated effects on students' satisfaction across the study locations. Therefore, relevant proposals to serve as fundamental requirements for developing an off-campus student housing model during pandemics were indicated.

It is seen that emerging building designs across the housing sector are equally evolving among off-campus student housing. The study helped to understand that student satisfaction with emerging building designs and basic services is a motivational need for students. However, the preparedness of student housing owners to adopt and satisfy the requirements of these design require further studies.

While COVID-19 and its associated effect keep evolving in building design requirements, it is equally relevant to assess the students' satisfaction with these designs and services among single room occupancy-made off-campus student housing. This research is limited to Africa.

The purpose of this study is to explore user satisfaction with in-house facility management (FM) services in multi-tenanted office buildings in Accra, Ghana using a post-occupancy evaluation (POE) approach.

The study assessed user satisfaction with FM service quality by using a POE of their perceptions about the attitude and courtesy of the FM personnel, the reliability of the FM services they provide, the responsiveness and the competence of the service providers. The study used walk-throughs and questionnaire surveys as the POE methods. One hundred and twenty-one users from 22 multi-tenanted office buildings, who have actively used the FM services for at least a year, were purposively sampled. The data was collected via a survey using a structured questionnaire. The data was analysed using descriptive statistics and principal component analysis in version 25 of statistical package for the social sciences.

The study revealed that users were dissatisfied with the quality of in-house FM services across all 15 services The results also showed that users’ satisfaction with the services is not affected by the differences in their age, gender, educational level, job role and number of years in the buildings. The results further demonstrated that the most critical factors that resulted in users’ dissatisfaction were electric facilities, building fabric maintenance, emergency coordination, waste management and the decoration of the buildings during festive seasons.

To the best of the authors’ knowledge, the present study based on POE to assess user satisfaction with FM services for multi-tenant office buildings has, presumably, not been tackled before in Ghana. The results of the study are very essential to the owners of the buildings and facility managers in decision-making concerning the delivery of FM services. Building industry-wise, the results demonstrate the need for in-house FM managers in multi-tenanted office buildings in Ghana to adopt FM service delivery methods that increase user satisfaction. The results also call for further research into user satisfaction with outsourced FM services in multi-tenanted office buildings and further research on the use of the in-house strategy on other types of buildings to ascertain whether the dissatisfaction with FM is due to other factors such as the choice of FM strategy, the property type etc.

Facilities management (FM) plays a key role in the performance of businesses to ensure the comfort of users and the sustainable use of natural resources over operation and maintenance. Nevertheless, reactive maintenance (RM) services are characterised by delays, waste and difficulties in prioritising services and identifying the root causes of failures; this is mostly caused by inefficient asset information and communication management. While linking building information modelling and the Internet of Things through a digital twin has demonstrated potential for improving FM practices, there is a lack of evidence regarding the process requirements involved in their implementation. This paper aims to address this challenge, as it is the first to statistically characterise RM services and processes to identify the most critical RM problems and scenarios for digital twin implementation. The statistical data analytics approach also constitutes a novel practical approach for a holistic analysis of RM occurrences.

The research strategy was based on multiple case studies, which adopted university campuses as objects for investigation. A detailed literature review of work to date and documental analysis assisted in generating data on the FM sector and RM services, where qualitative and statistical analyses were applied to approximately 300,000 individual work requests.

The work provides substantial evidence of a series of patterns across both cases that were not evidenced prior to this study: a concentration of requests within main campuses; a balanced distribution of requests per building, mechanical and electrical service categories; a predominance of low priority level services; a low rate of compliance in attending priority services; a cumulative impact on the overall picture of five problem subcategories (i.e. Building-Door, Mechanical-Plumbing, Electrical-Lighting, Mechanical-Heat/Cool/Ventilation and Electrical-Power); a predominance of problems in student accommodation facilities, circulations and offices; and a concentration of requests related to unlisted buildings. These new patterns form the basis for business cases where maintenance services and FM sectors can benefit from digital twins. It also provides a new methodological approach for assessing the impact of RM on businesses.

The findings provide new insights for owners and FM staff in determining the criticality of RM services, justifying investments and planning the digital transformation of services for a smarter provision.

This study represents a unique approach to FM and provides detailed evidence to identify novel RM patterns of critical service provision and activities within organisations for efficient digitalised data management over a building’s lifecycle.

Over the last 50 years, increased attention for personalization paved the way for one-to-one marketing efforts, but firms struggle to deliver on this promise. The purpose of this manuscript is to provide a complete picture on personalization, develop a future research agenda and put forth concrete advice on how to move the field forward from a theoretical, methodological, contextual, and practical viewpoint.

This research follows a systematic literature review process, providing an in-depth analysis of 135 articles (covering 184 studies) to distill the (1) key building blocks and components of personalization and (2) theoretical, contextual, and methodological aspects of the studies.

This manuscript uncovers six personalization components that can be linked to two personalization building blocks: (1) learning: manner, transparency, and timing and (2) tailoring: touchpoints, level, and dynamics. For each of these components, the authors propose future research avenues to stimulate personalization research that accounts for challenges in today's data-rich environments (e.g. data privacy, dealing with new data types). A theoretical, contextual, and methodological (i.e. industry, country and personalization object) review of the selected studies leads to a set of concrete recommendations for future work: account for heterogeneity, embed theoretical perspectives, infuse methodological innovation, adopt appropriate evaluation metrics, and deal with legal/ethical challenges in data-rich environments. Finally, several managerial implications are put forth to support practitioners in their personalization efforts.

This research provides an integration of personalization research beyond existing and outdated review papers. Doing so, it accounts for the impact of new technologies and Artificial Intelligence and aims to advance the next generation of knowledge development on personalization.
