Nowadays it is typical that the precise use of a building becomes clear during construction. Current building processes do not support this in Finland. The objective of this study is to present a novel systematic management of the design process for flexible construction projects, from the project programming stage through to overall design, detailed designs, procurement, and handover, in a situation where the final use of the building becomes clear only during construction.

The development work included a constructive search for solutions to the problems presented above. The process developed in this study is illustrated with two case projects analysed retrospectively.

According the open building principle, buildings should be divided into two parts: a permanent base building; and modifiable interior spaces. This division should apply throughout the building's entire life cycle, starting from the beginning of the construction project. The start of the project is the time when goals should be set for the flexibility of the building. The first step in this goal‐setting procedure is to define the flexible modifiable spaces, and the second step is to dimension the permanent base building. A design procedure for this open building procedure has also been developed in the study. The study concludes that traditional boundaries and the content of design packages must be changed. These boundaries should be compatible with the appropriate bid packages and should support implementation of the construction work. The bid packages should follow the division to base building and spaces too.

The procedure proposed forms guidelines for flexible programming, basic principles for design and procurement processes. In addition, it is the starting point to transforming the Finnish standard scope of work for design corresponding to the open building approach.

It is important to provide building performance feedback to the designer as early as possible in the design process. However, many aspects of building performance are significantly affected by the design of the building’s technical systems (e.g., heating, airconditioning), which are typically configured in detail only in the later stages of design. The challenge is thus to find a method to use detailed simulation tools even during the early stages of design when values for many of the variables for the building’s technical systems are not yet available. In this paper, we demonstrate how this problem can be partially solved by use of differential representation for building and technical system, homology‐based automatic mapping of relevant information from the building to the technical system representation, and generative design agents which, with a minimal user‐input, can design and model the technical system. We conclude the paper with illustrative examples of detailed performance analysis of complex buildings and their heating, ventilation, and air‐conditioning systems, performed in early stages of design.

Open Building and IFD (Industrial Flexible Demountable) building are philosophies that aim to create high quality buildings with increased flexibility and better environmental characteristics. However, a successful adoption of IFD principles has not yet occurred because of concerns for the types of connections that are needed between building components. Therefore, this paper describes PhD research at the University of Twente that has the objective of designing a typology of flexible interfaces for IFD building that can be widely applied in the construction industry and aims to standardize connections, at the various levels of technical composition of a building, to create compatibility between building products from different suppliers. Such a typology of interfaces will increase the re-use and recycling of building parts, resulting in the increased sustainability of the building process. Furthermore, it will help accelerate the industrialization of the housing industry and mass customization of housing. A preliminary case study, in which a sustainable, flexible bathroom is designed, illustrates the various types of interfaces that can be applied, based on existing research. The paper illustrates the importance of interfaces, and aims to increase environmental benefits of buildings (less construction waste), improve the social aspects (higher user satisfaction in buildings) and achieve economical advantages (lower overall costs) by designing new interfaces.

The purpose of this study is to identify and evaluate the primary constraints that quantity surveying firms in Nigeria encounter while integrating indoor environmental quality (IEQ) principles into building designs.

The study used a quantitative approach by administering a well-structured questionnaire to 114 quantity surveyors. The collected data were analyzed using methods such as frequencies, percentages, mean item scores, Kruskal–Wallis test and exploratory factor analysis.

The top five ranked constraints were limited access to funding or financing options, limited availability of green materials, limited availability of insurance for sustainable buildings, limited availability of sustainable design resources and limited diversity and inclusivity within the design profession. Based on the factor analysis, the study identified six clusters of constraints: structural-related constraints, technical-related constraints, financial-related constraints, capacity-related constraints, legal-related constraints and culture-related constraints.

This study has several practical implications for quantity surveying firms, policymakers and industry stakeholders involved in building design and construction in Nigeria. The findings of this study can also inform future research on the integration of IEQ principles into building designs.

By identifying and structuring the clusters of constraints faced by quantity surveying firms in Nigeria when implementing IEQ principles, this study provides a novel approach to understanding the challenges associated with IEQ implementation in the building sector. This understanding can guide policymakers, industry stakeholders and quantity surveying firms in developing effective strategies to overcome these constraints and promote IEQ principles in building design and construction.

This exploratory study, a Ph.D. dissertation completed at the University of Western Ontario in 2013, examines the materially embedded relations of power between library users and staff in public libraries and how building design regulates spatial behavior according to organizational objectives. It considers three public library buildings as organization spaces (Dale & Burrell, 2008) and determines the extent to which their spatial organizations reproduce the relations of power between the library and its public that originated with the modern public library building type ca. 1900. Adopting a multicase study design, I conducted site visits to three, purposefully selected public library buildings of similar size but various ages. Site visits included: blueprint analysis; organizational document analysis; in-depth, semi-structured interviews with library users and library staff; cognitive mapping exercises; observations; and photography.

Despite newer approaches to designing public library buildings, the use of newer information technologies, and the emergence of newer paradigms of library service delivery (e.g., the user-centered model), findings strongly suggest that the library as an organization still relies on many of the same socio-spatial models of control as it did one century ago when public library design first became standardized. The three public libraries examined show spatial organizations that were designed primarily with the librarian, library materials, and library operations in mind far more than the library user or the user’s many needs. This not only calls into question the public library’s progressiveness over the last century but also hints at its ability to survive in the new century.

This study explores the utilization of simulation tools for building performance assessments among design professionals in Ghana.

A quantitative approach was used to obtain responses from 104 design professionals in Ghana through a structured questionnaire. The questionnaire was generated through a critical review of the related literature on the subject matter. Data from respondents were analyzed through descriptive and inferential statistics.

Results from the analysis indicated that design professionals in Ghana possessed a low level of awareness of the simulation tools used for building performance assessments. Subsequently, the findings also revealed that the design professionals' level of usage of the simulation tools was low.

Practically, the establishment of this study informs design stakeholders, educational institutions and researchers in Ghana. For design professionals, these findings will focus on enhancing their use of simulation tools for evaluating building performance in Ghana. For educational institutions, these findings will enable them to implement the necessary strategies for incorporating the concept of building performance simulation into their curriculum in order to boost awareness and utilization. Finally, researchers will also use the study's findings to identify any research gaps for future studies.

The findings from this study pioneer knowledge on an under-investigated topic within the Ghanaian construction industry. It also provides insight into the developing state-of-the-art technology employed in the built environment.

Despite many studies on buildability from different perspectives and methods, the problems associated with buildability have not ceased from confronting the construction industry. This paper aims to determine the critical measures for improving the buildability of building designs in the construction industry.

A questionnaire was developed to address the aim of the study. Data were collected through the administration of questionnaires to purposively selected group of quantity surveyors, builders, engineers and architects. A total of 368 questionnaires were administered and a response rate of 60% (219 questionnaires were returned) was achieved. Data elicited were analysed using descriptive and inferential statistics.

The results revealed that “the benefits of improved buildability should be made known to designers”, “more technical literature for improving buildability should be provided to designers” and “more education and training on buildability should be given to designers” are the top most important three measures for improving the buildability of building designs in the construction industry.

This study highlights the measures for improving buildability of building designs which are considered significant by construction professionals. An understanding of these measures is essential for reducing buildability problems as well as for improving and embedding buildability as a practice in the construction industry.

The construction industry is shifting towards becoming more circular by reducing waste, reusing building materials and embracing regenerative solutions for energy generation and biodiversity conservation. Thus, construction professionals must perform diversified services to achieve a circular built environment (CBE). Implementing resource planning and waste management in CBE has already posed challenges to the quantity surveying profession; thus, quantity surveyors (QSs) should be equipped with new roles and competencies to tackle challenges in achieving a CBE. Hence, this study aimed to investigate the functions and competencies of QSs at the design and building material sourcing stages in achieving a CBE according to 3R principles.

The research apprehended a qualitative approach, including two expert interview rounds adhering to the Delphi technique with 14 and 11 experts per each round. Manual content analysis was incorporated to analyse the collected data.

The research findings revealed the important roles and competencies of QSs in achieving a CBE. In addition, essential functions and competencies were categorised according to the 3R principles (reduce, reuse, recycle) to successfully implement CBE during the Design and Building Material Sourcing stages. According to the 3R principles of CBE, cost control, cost planning, feasibility studies, measurement and quantification, risk management, value engineering and innovations and technologies were well-received by most interviewees as essential roles of QSs during the Design and Building Material Sourcing stages. Further, basic/mandatory competencies (personal, interpersonal, professional practice and business skills), economic analysis, BIM management, cost management and risk management are highly regarded by experts for QS as important competencies to achieve CBE.

With new construction trends, QSs must enhance their conventional roles and competencies and search for new skills and competencies. Those skills and competencies could be linked to the CE concept, either directly or indirectly. Since QS holds a prominent place in sustainable construction in CBE, adapting to changes in the construction industry such as CBE is timely for QSs. Further, there is a shortage of literature regarding QSs' roles and competencies in achieving a CBE; thus, this study will contribute by identifying new avenues for QSs in achieving a CBE in the practice and the research.

Design for adaptability and disassembly (DfAD) is an effective method to reduce construction and demolition waste generation, landfill loads and greenhouse gas generation; preserve natural resources; and increase environmental awareness in the construction industry. However, it is an underexplored strategy due to a lack of information about projects and a set of agreed guidelines to guide buildings deconstruction. This study aims to understand how DfAD can support the sector’s transition toward circularity.

Through an integrative literature review, this study analyzed the current publications and terminologies used, identified the main themes discussed and described the key criteria for integrating deconstruction in the building design stage.

The results showed that the term DfAD encompasses different ecodesign strategies and is concentrated in six major thematic categories (design and construction principles, tools for DfAD, components and connections for DfAD, barriers, drivers and guidelines for DfAD, existing building stock potential and selective deconstruction process). In total, 60 criteria were presented to guide the deconstruction of buildings, emphasizing standardization, modularization and prefabrication of materials and components as fundamental requirements.

The study highlighted the need to expand the knowledge and training of the design team, establish public policies and tax incentives and develop tools, methods, and circular indicators to enable the implementation of deconstruction strategies for 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.
