TL;DR: In this article, the verification of a Building Environmental Assessment System (BEAS) was performed on a set of 13 detached family houses representing typical construction sites in Slovakia and the results showed that the weakest fields of sustainability are waste management, energy performance, and building construction.
Abstract: The presented study is focused on the verification of a Building Environmental Assessment System (BEAS). A total of 13 detached family houses representing typical construction sites in Slovakia were chosen for analysis, evaluation and certification by using a BEAS which contains several main fields: A—Site Selection and Project Planning; B—Building Construction; C—Indoor Environment; D—Energy Performance; E—Water Management; and F—Waste Management. The results of this study show that the current construction method for family houses does not respect the criteria of sustainable construction as much as it possibly can. The reason for this is that investment costs for construction are prioritized over environmental and social aspects. Therefore, one house with a score of 1.10 is certified as BEAS BRONZE, ten family houses with scores of 1.56–2.88 are certified as BEAS SILVER and only two family houses with total scores of 3.59 and 3.87, respectively, are certified as BEAS GOLD. The overall results show that the weakest fields of sustainability are Waste management, Energy performance and Building construction. The best-rated fields are Site Selection and Project Planning, Indoor Environment and Water Management. In the future, it is essential to pay attention to those areas where the sustainability criteria have not been reached, as well as to raise project teams’ awareness of sustainability issues and subsequently to transfer them to building practices.

TL;DR: It is recommended that MCDM methods be taught in semester courses to students in training so that they can develop a deep understanding of these tools and can demonstrate their usefulness for decision making where there are many variables to consider, where there is many decision-makers, and for the incorporation of sustainable factors for project evaluation.
Abstract: Currently, there is a need for civil engineering programs to train their students in subjects associated with sustainability. Additionally, civil engineers in their work must constantly make decisions, so their training is necessary. Therefore, the goal of this research is to present a methodology for teaching multi-criteria decision-making methods in the context of civil engineering and road infrastructure projects using sustainable factors. To achieve the objective of this study, a decision-making simulation activity has been designed based on a five-step research process: (1) definition and contextualization of the case study; (2) design and planning of the simulation activity; (3) implementation of this activity; (4) evaluation of indicators; and (5) statistical analysis of metrics. The teaching methodology used is of a practical-theoretical type and allows for the step-by-step teaching of three multi-criteria decision making (MCDM) methods that, according to the literature review, are widely used in the architecture, engineering, and construction (AEC) industry. This teaching activity is intended for undergraduate students and professionals in the AEC industry who require a decision-making tool that promotes transparency in problem-solving and who have no knowledge of MCDM. The results obtained in this research show that the method perceived by the group of students with the least difficulty was the weighting rating and calculating (WRC), because of its previous familiarity and use in academic environments. It is recommended that MCDM methods be taught in semester courses to students in training so that they can develop a deep understanding of these tools and can demonstrate their usefulness for decision making where there are many variables to consider, where there are many decision-makers, and for the incorporation of sustainable factors for project evaluation.

TL;DR: This study has two sub-goals; the development and adaptation of recycled polyvinyl butyral to increase the elevation of the healthy residential buildings and design a methodology, and create databases and intelligent designs, via knowledge and building information modeling (BIM) technologies.
Abstract: Healthy residential buildings represent the future of construction concerned with the environment, which is increasingly emphasized. This is directly related to the research and development of environmentally friendly building materials, which on the one hand meet the specific requirements of the builder, and on the other hand do not harm the environment. The research is based on the possibility of achieving increased variability in healthy residential buildings via the customization of recycled polyvinyl butyral using smart technologies for sustainable design. This study has two sub-goals; the first and foremost is the development and adaptation of recycled polyvinyl butyral to increase the elevation of the healthy residential buildings. The second objective is to design a methodology, and create databases and intelligent designs, via knowledge and building information modeling (BIM) technologies. In future research, data on environmental materials (such as the abovementioned recycled polyvinyl butyral) should be implemented in the knowledge databases that will be methodically described in our second sub-target.

TL;DR: In this article, an overview of evaluation methods of investments to smart technology in construction projects is presented, which can be applied and used in assessing investments in advanced technologies in the construction industry.
Abstract: Smart technologies and solutions have represented an increasing growth in every industry over the last decade . Many of the smart solutions are focused on improvement with a view to sustainability. The basis of smart solutions is advanced technologies and interactive systems that respond to changed conditions. These technologies are increasingly being implemented in the field of construction and intelligent buildings or urban areas. The construction industry shows great possibilities for the implementation of smart and progressive technologies. However, construction projects represent a volume-intensive investment. The same applies to the implementation of smart solutions, which, however, can also provide savings. This needs to be evaluated very much. It is necessary to use evaluation methods of investments in these solutions. This paper is largely devoted to the evaluation methods of investments in mobile applications and smart technology in the construction industry. The research aims to conduct an overview of evaluation methods of investments to smart technology in construction projects. Research also describes examples of the use of specific smart solutions in the construction industry and urban planning. The output of the research is an overview of Evaluation methods of investments, which can be applied and used in assessing investments in advanced technologies in construction.

TL;DR: In this paper, the authors considered the relationship between energy-efficient design and the leasing/sales markets for commercial real estate and provided an economic model that considers lease rates and occupancy in simultaneous equilibrium.
Abstract: This paper considers the relationship between energy-efficient design and the leasing/sales markets for commercial real estate. An economic model is provided that considers lease rates and occupancy in simultaneous equilibrium. The behavior of both is predicted to be influenced by efficient design attributes. Selling price is determined by both rents and occupancy; therefore the impact of efficient design on commercial sales activity should be distributed through the leasing market. The model is tested empirically using a national sample of sales and leasing data for class A office buildings. The evidence indicates that “green” buildings achieve superior rents and sustain significantly higher occupancy. The improved performance in the rental market is reflected in a significant premium for the selling price of Energy Star-labeled and LEED-certified properties.

TL;DR: A review of definitions of sustainable building shows that the terminology needs clarification as many difficulties exist in identifying sustainability in the built environment as discussed by the authors, and some requirements for a better definition of a sustainable building are indicated.
