Selecting a construction contractor is a major decision which may influence the progress and success of any construction project. The paper analyses criteria used to evaluate qualification of contractors in Lithuania and abroad. Both in Lithuania and abroad, the bid price of construction works is the main criterion for evaluation of con‐tractors. The lowest price often cannot guarantee commitments on quality and duration of a construction project. Therefore, when selecting a contractor, a

A contractor must be selected according to both quantitative and qualitative criteria, and bids should be compared. Only on the basis of quantitative and qualitative evaluation criteria and by comparing bids of contractors it is possible to select a qualified, competent and reliable contractor, to evaluate its qualification, economic and financial condition and technical capability and skills and to achieve relevant results in a construction project. The paper provides an investigation of Lithuanian companies, which analyses issues related to evaluation of contractors' qualification. The paper is completed with a discussion of the investigation results and delivery of proposals based on expert estimations of the weight of criteria for evaluation of contractors.

Many real-life problems are multi-objective by nature that requires evaluation of more than one criterion, therefore MCDM has become an important issue. In recent years, many MCDM methods have been developed; the existing approaches have been improved and extended. Multi criteria decision analysis has been regarded as a suitable set of methods to perform sustainability evaluations. Among numerous MCDM methods developed to solve real-life decision problems, Technique for Order Preference by

In this paper, a novel sorting method (TOPSIS-Sort) based on the classic TOPSIS method is presented. In the TOPSIS-Sort approach an outranking relation is used for sorting purposes. The proposed approach uses characteristic profi les for defi ning the classes and outranking relation as the preference model. Application of the proposed approach is demonstrated by classifying 22 districts of Tehran into fi ve classes (but none of the districts fi ts into Classes 4 and 5), representing areas with different levels of environmental quality. An analysis and assessment of the environmental conditions in Tehran helps to identify the districts with the poor environmental quality. Priority should be given to these areas to maintain and improve the quality of environment. The results obtained by the TOPSIS-Sort give credence to its success, because the results of sorting confi rm our and specialists' evaluation of the districts. This research provides appropriate results with respect to the development of sorting models in the form of outranking relations. The model, proposed by this study, is applicable to the other outranking methods such as ELECTRE, PROMETHEE, etc.

This paper aims to identify and investigate the factors affecting the goals of mass-housing building projects due to the use of building information modeling (BIM). A descriptive-survey method was used to collect necessary data. Fifty respondents from the target sectors and experts in the field of modeling building information participated in self-selection survey. The tools of collecting data included three questionnaires regarding three phases of construction work: pre-construction, during
more » ... struction and post-construction, which were developed based on the three indices of cost, time and quality. The face, content and construct validity of the questionnaires were confirmed after several rounds of testing. The reliability coefficient of the pre-construction, during the construction and post-construction questionnaires were 0.923, 0.917 and 0.876, respectively. The results show that the F-statistic is significant for the difference between the three groups (pre-construction, during construction and post-construction) at the 0.01 level. The results confirmed that BIM has a great influence on a project in terms of meeting time, cost and quality objectives through the whole life cycle of a construction project: during pre-construction, construction, and post-construction stages.

Construction, as an object of marketing, has special features: the construction environment is complex and changing, clients' requirements and expectations are increasing. Construction companies must realize that good marketing, as well as advertising activities have a great impact on sales of construction products and services in today's competitive market. This paper reports on a qualitative study of the Lithuanian and Swedish construction companies about advertising campaign, budget and
more » ... of advertising. The effectiveness of advertising means is also analyzed. The first problem identified in the study is that most Lithuanian construction companies provide self‐advertising policy. The lack of experience and knowledge of advertising leads organizations to inadequate decisions. The observations also detected that advertising campaign in the Lithuanian construction companies is underfinanced and the advertising budget is closely linked with used means. The paper concludes with the assessment of the study results and directions for further research.

Office buildings built before the pre-1960 age constitute a relevant group for analyzing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. By using a staged renovation approach, two passive technologies applied to the building envelope and an efficient domestic hot water system were selected and a financial evaluation through the net saving (NS)
more » ... method was undertaken to choose the best efficiency measures/packages for improving the building's energy performance. Real discount rates of 3% and 1% were used in the financial evaluation. Considering the real discount rate of 3%, the results showed that only two out seven retrofit options had a positive financial return. By using the real discount rate of 1%, all retrofit options were found to be financially efficient. The results of the study corroborated those of earlier works that found that the financial profitability of energy renovation investments is very sensitive to the discount rate used in the analysis. The results of the study also suggested that the staged renovation approach used in the analysis is economically feasible, and that this approach is an alternative to one-step renovation approach to help to achieve the country´s energy and climate targets by 2030. Suggestions for future research conducted for office buildings in the different climate zones and other age groups in Portugal are proposed.

This paper identifies a list of sustainability indicators for examining the supply chains of construction companies. Those indicators were categorized and assigned to one or a couple groups by reviewing their use in the previous literature agreeing to the reasoning to way better reflect the SSCM principle of their use in construction companies. The use of indicators can help develop strategies for the construction sector for sustainable policy makers and construction company managers.

Owing to the advantages of high construction efficiency, prefabricated residential buildings have been of increasing interest in recent years. Against the background of global heating, designing low-carbon facades for prefabricated residential buildings has become a focus. The main challenge for this research is in designing windows for prefabricated residential buildings that can lead to the best performance in carbon emissions. The purpose of this paper is to summarize window design advice
more » ... prefabricated residential building facades with low-carbon goals. This paper adopts the single control variable research method. Building energy consumption and carbon dioxide emissions under different conditions comprise the primary data used in the study. In the process of achieving the research aim, this study firstly extracts the window design elements of prefabricated residential facades. Secondly, objective function formulas are established and a basic model is built for obtaining data. Thirdly, data results are analyzed and window design advice is put forward under the condition of a low-carbon goal. This paper discusses that the optimal window-to-wall ratio (WWR) with a low-carbon orientation is around 0.15, and compares it innovatively with the optimal WWR under an energy-saving orientation at around 0.38. The research results of this paper can deepen the understanding of architectural low-carbon design and play a guiding role for architects.

House purchasing has become an important asset allocation choice for most families in China. House price fluctuation is also one of the important factors that leads to systematic risks in the financial market, which might cause economic crises and then reduce consumption. Since China formally established the dual-pillar management framework of macroprudential policy in 2019, it has played a crucial role in maintaining the stability of house prices. This article employs the mediating effect

Experience implies that macroprudential policy can not only stabilize consumption demand directly and effectively, but also affect consumption indirectly through the cross of the real estate market and the credit market. Further research has also found that macroprudential policies may fail between regions with higher GDP and high-income groups. This finding will contribute to research on the relationship between macroprudential policies and real economics. In addition, it would be helpful in making policies to increase consumption.

2018 Sustainability  
The concept of university-industry partnership sustainability (UIPS) stands for well-adjusted progress among key players from universities and industry by sustaining their welfare, both in the present and in the future. This paper sought to develop an evaluation system for UIPS. The need for such a system is justified at three levels: the micro level (i.e., research and innovation performance, transfer and absorptive capability, and technology development), the meso level (i.e., institutional
more » ... rangements, communication networks, and local and indigenous rules) and the macro level (i.e., supply and demand, regulations, financing, taxes, culture, traditions, market, climate, politics, demographics, and technology). The UIPS evaluation system developed in this study offers the possibility of calculating a fair value of UIPS and providing recommendations for improving university-industry (U-I) partnerships. This can be of great importance for entrepreneurial universities that would like to strengthen their corporate links and/or reduce/reverse the "hollowing effect" of globalisation in disadvantaged regions. Additionally, this paper also contains discussions on the advantages, limitations, and managerial implications of this proposal. collaboration activities between academia and industry. Plewa et al. [18] analysed the evolution of university industry linkage phases: pre-linkage that leads to an agreement to work together, establishment that leads to a contract, engagement that leads to the delivery of a project, advancement that leads to an ongoing partnership as well as word of mouth, and the latent phase that means potential future cooperation should a suitable project arise, with continuing personal linkage. Ankrah and Al-Tabbaa [19] employed a systematic procedure to review the literature on university-industry (U-I) collaboration. Ankrah and Al-Tabbaa [19] examined three main phases in U-I collaboration: formation (identifying partners, making contact, assessing partners, negotiation, agreement signing), organisational forms (informal and formal personal relationships, third party, targeted and untargeted formal agreements, focussed structures), and operational phase activities (meetings, communication, trainings, personal mobility, employment, other activities). The effort to make the life cycle of U-I partnerships and their components more sustainable involved the development of a wide range of different databases, evaluation techniques and intelligent systems (i.e., expert, knowledge, fuzzy, embedded, and decision support mechanisms) [20] [21] [22] [23] . The U-I interface system and the interactive academic-industry partnership database enable academic investigators and industry to match up their needs based on complementary knowledge, initiate contact, and work to develop effective partnerships [24] . U-I partnership approaches (e.g., multidisciplinary, linear, market-led, bottom-up, top-down, and cross-disciplinary, among many others) have limitations in terms of results, generalisations and practical impacts on the community [11, 15, 25] . The present study sought to address this gap by analysing some of the existing multiple criteria decision analysis (MCDA) methods and identifying possibilities for improving the effectiveness of the approaches towards UIPS evaluation. Specifically, the literature review suggests that the methods and systems currently available offer no possibility to calculate a fair UIPS value, and provide recommendations for improving U-I partnerships. Furthermore, the available techniques and software packages are unable to optimise the selected criteria, which might otherwise generate an opportunity for further developments. The INvestment Value Assessments along with Recommendation provisions (INVAR) method [26] can be used for assessing a U-I partnership by using the same data as other MCDA methods. However, by applying the INVAR method, it is additionally possible to determine the fair value of a U-I partnership under consideration, optimise the parameters and composite parts of mutual cooperation, and provide well-informed recommendations for improving cooperative work. This means that the INVAR method can support the evaluation of U-I partnerships in a new form, thereby adding to the extant literature on U-I collaboration, entrepreneurship, and operational research. The structure of the remainder of this paper is as follows. Section 2 presents a review of related work. Section 3 presents the methodology and the INVAR method along with sketches of the components of the multiple criteria assessment system developed for UIPS. Section 4 presents a practical application of the developed UIPS system, and discusses its impact for entrepreneurial universities. Section 5 concludes the paper and lays the groundwork for future research. Related Work U-I collaborations have increased in number and variety over the past few decades [20, 21, [27] [28] [29] . These involve a wide range of UIPS variables, including databases and knowledge tools (e.g., software, expert, fuzzy, embedded, and decision support mechanisms). Figure 1 presents some of these elements, which are considered of extreme importance for increasing the entrepreneurial activity of universities [10, 13, 30] .
