The built environment has changed dramatically due to the increased interest in mitigating climate change. Homes are becoming more energy-efficient, responding to energy issues, and reducing carbon emissions primarily. Nevertheless, we started to realize the unintended consequences of these changes that impact a home's indoor environment and occupants' health. Indoor air quality is a critical aspect as indoor pollutants are increasing in homes. More than ever, it is crucial to adhere to the best ventilation practices, building materials, and cleaning products. Additionally, behaviour changes, such as those for healthy homes, can prevent their health impact. Interdisciplinary research between public health and building professionals needs to educate citizens and present evidence for legislative changes and recommendations to spur change to reduce indoor air pollution and protect vulnerable populations preventing harmful effects on future generations' health.

The article is aimed at forming an express assessment of the level of economic security for a construction enterprise (which, unlike others, is based on an assessment of the level of efficiency of management of contractors and subcontractors) and the choice of a special package of measures to increase the level of economic security. The article analyzes the current state of the civil construction industry in Ukraine, market characteristics of this sector of the economy. There was a decline in the construction sector during 2020–2021, especially in the first half of 2021. Further, there is a slowdown in labor migration, some supply chains of building materials are interrupted; respectively, there is a need to resume economic activity. Also, theoretical studies of the authors allowed to highlight the main aspects of the formation of economic security of enterprise through the analysis of the relevant market and the dynamics of the civil construction industry. The relevance of creating an express assessment of the level of economic security of a construction enterprise is substantiated. An express assessment is proposed to be carried out on the basis of determining the level of efficiency of management of contractors and subcontractors – to what extent they adhere to the traditional policy of value and income formation. The assessment methodology includes four stages: questionnaire (containing 20 questions in four directions of evaluation); processing of questionnaire data (Delphi method is used); formation of an evaluation scale to determine the level of economic security of a construction enterprise; selection of a package of measures to improve the economic security of civil construction enterprises. The packages of measures to improve the economic security of civil construction enterprises are being developed for both the formal and the informal sectors. The authors believe that it is advisable to adapt the proposed package of measures to the characteristics of each individual enterprise using an individual approach. The proposed express assessment will allow monitoring the condition of the construction enterprise in a short time and identify latent crisis phenomena.

The construction industry is a vital part of the modern economic system. Construction work often has significant negative impacts on the environment and sustainable economic development, such as degradation of the environment, depletion of resources, and waste generation. Therefore, environmental concerns must be taken into account when evaluating and making decisions in the construction industry. In this regard, sustainable construction is considered as the best way to avoid resource depletion and address environmental concerns. Selection of sustainable building materials is an important strategy in sustainable construction that plays an important role in the design and construction phase of buildings. The assessment of experts is one of the most important steps in the material selection process, and their subjective judgment can lead to unpredictable uncertainty. The existing methods cannot effectively demonstrate and address uncertainty. This paper proposes an integrated Dempster-Shafer (DS) theory of evidence and the ARAS method for selecting sustainable materials under uncertainty. The Dempster-Shafer Evidence Theory is a relatively new and appropriate tool for substantiating decisions when information is nonspecific, ambiguous, or conflicting. The Additive Ratio Assessment (ARAS) method has many advantages to deal with MCDM problems with non-commensurable and even conflicting criteria and to obtain the priority of alternatives based on the utility function. The proposed method converts experts’ opinions into the basic probability assignments for real alternatives, which are suitable for DS evidence theory. It uses the ARAS method to obtain final estimation results. Finally, a real case study identifying the priority of using five possible alternative building materials demonstrates the usefulness of the proposed approach in addressing the challenges of sustainable construction. Four main criteria including economic, social, environmental, and technical criteria and 25 sub-criteria were considered for the selection of sustainable materials. The specific case study using the proposed method reveals that the weight of economic, socio-cultural, environmental, and technical criteria are equal to 0.327, 0.209, 0.241, and 0.221, respectively. Based on these results, economic and environmental criteria are determined as the most important criteria. The results of applying the proposed method reveal that aluminum siding with a final score of 0.538, clay brick with a score of 0.494, and stone façade with a final score of 0.482 are determined as the best alternatives in terms of sustainability.

PurposeThe purpose of this paper is to develop the empirically tested framework about the knowledge and perception about sustainability of building materials in Prishtina, Kosovo from the perspective of users, construction industry and facility managers. Design/methodology/approachA survey of representative sections of the population was designed and carried out in the capital city of Kosovo to determine the knowledge and perception of the population about the sustainability of building materials and to determine the main criteria of selection of sustainable building materials. The study may be used as guidelines for sustainable real estate developers in Prishtina during the materials selection process. Qualitative interviews were conducted with architects, consulting engineering companies, construction companies and facility managers from the region of Prishtina with open-ended questions also being used. FindingsResults of quantitative research find that embodied energy, durability and low energy consumption are used as key criteria that influence the materials selection process on the part of users. The results of the cross-case analysis of qualitative measure the perceptions of construction industry and facility managers, according to which durability to a large degree is the main criterion for selection of sustainable building materials followed by embodied energy and low energy consumption. Research limitations/implicationsThe study of measurement of level of knowledge and perception about sustainability of building materials in Kosovo focuses only on one pilot city; hence, further research is needed throughout Kosovo to validate the empirically tested tool within other geographical settings in Kosovo. Originality/valueThis survey represents the first quantification of knowledge and perception regarding the sustainability of building materials among users, construction sector and facility managers.
