Design Proposal

In view of new construction market and National Project requirements, there is a growing demand in the construction environmental specialists in this field. The article analyses the results of scientific and practical developments in ecological restoration which are being implemented to a degree in the municipal economy and construction. This field of activity has been poorly researched in the studies yet, but it has been already used in construction of unique buildings and constructions, and ecological construction projects. The author has compared the assessment criteria of investment projects for standard (S) and energy-efficient houses (E). The life cycle analysis results provide for assessing the energy-efficient house and confirm that the rising cost at the construction stage is repaid for multiple times at the operation stage. The research has shown that the 2% investment rise for construction of the energy-efficient house would increase the return on investment by 10 times during the building life cycle. Such return is achieved due to energy cost saving. It can be noted that to construct an energy-efficient house as an option of ecological restoration design proposal implementation, various technologies which can both increase and reduce construction cost are used. The increased energy efficiency has a powerful economic and environmental effect and is of interest not only for the enterprises and creditors, but also for the public as to the positive results of the energy efficient project implementation, the increased economic and environmental safety of the country are the additional advantages of the energy efficient building construction that increase the attractiveness of such projects for the bank investment lending.

Energy efficient buildings are viewed as one of the solutions to reduce carbon emissions from the built environment. However, studies worldwide indicate that there is a significant gap between building energy targets (as-designed) and the actual measured building energy consumption (as-built). Several underlying causes for the energy performance gap have been identified at all stages of the building life cycle. Focus is generally on the post-occupancy stage of the building life cycle. However, issues relating to the construction and commissioning stages of the building are a major concern, though not usually researched. There is uncertainty on how to address the as-designed versus as-built gap. The objective of this review article is to identify causes for the energy performance gap in buildings in relation to the post-design and pre-occupancy stages and review proposed solutions. The methodology applied in this research is the rapid review, which is a variant of the systematic literature review method. Findings suggest that causes for discrepancies between as-designed and as-built energy performance during the construction and commissioning stages relate to a lack of knowledge and skills, lack of communication between stakeholders and a lack of accountability for building performance post-occupancy. Recommendations to close this gap during this period include better training, improved communication standards, collaboration, energy evaluations based on post-occupancy performance, transparency of building performance, improved testing and verification and reviewed building standards.

Purpose – the purpose of this research is to find the benchmark, triggering a significant shift of the EU transport infrastructure construction sector from usual labour to the IT-based project implementation. The work aims to find obstacles that hold off IT from booming in this sector. Research methodology – following the literature overview, three bills of quantities of sample transport infrastructure construction projects selected as the objects for analysis and the mathematical-statistical method was applied to actually completed projects to find the benchmark for costs of respective IT development. Findings – the findings of this work suggest a 10% benchmark of project scope, applicable for IT innovations at the expense of human labour demand. Research limitations – EU financial support and public procurements of investment projects are mostly applicable for investment phase. This research is therefore limited to the analysis of investment activities. Practical implications – the industry stakeholders would welcome the IT if innovations developed with the budget not exceeding the benchmark. IT researchers and developers could use the results for cost adjustments of their offered solutions to the EU transport construction companies. Originality/Value – this work encourages discussions on initiation of the initiatives at the political level aiming to the requalification of the existing unemployed labour force in order to meet the current labour demand in the construction market as a whole. It provides a direction for future scientific researches and IT developers in order to increase the attractiveness of IT for application in construction projects.

Efficient Construction

Within the framework of the concept of sustainable development, issues of energy efficiency, environmental safety, minimization of anthropogenic impact on the environment are of particular relevance. In construction, these theses are projected onto the segment of energy-efficient, “green” construction. Nowadays, the development of energy-efficient construction in Russia is progressing at a slow pace, and this is primarily due to the lack of an integrated energy management system, environmental certification of construction products, and institutional features of the real estate market. The authors systematized the methods of improving energy efficiency and greening of construction regarding the types of real estate, analyzed the main global and Russian environmental certification systems in construction, identified the features, advantages and disadvantages of each system, substantiated the need to ensure the generally accepted Russian certification system. The problem of enhancing energy-efficient construction is also interconnected with the need to increase the level of innovation in construction, which is substantiated by the authors in the paper. The authors substantiated the need to change the criteria for monitoring investment projects, taking into account the optimization of energy efficiency and environmental performance of real estate.

The starting stage of the tender procedures in Russia with the participation of foreign suppliers dictates the feasibility of the developments for economical methods directed to comparison of technical solutions on the construction field. The article describes the example of practical Life Cycle Cost (LCC) evaluations under respect of Present Value (PV) determination. These create a possibility for investor to estimate long-term projects (indicated as 25 years) as commercially profitable, taking into account inflation rate, interest rate, real discount rate (indicated as 5 %). For economic analysis air-blower station of WWTP was selected as a significant energy consumer. Technical variants for the comparison of blower types are: 1 - multistage without control, 2 - multistage with VFD control, 3 - single stage double vane control. The result of LCC estimation shows the last variant as most attractive or cost-effective for investments with economy of 17,2 % (variant 1) and 21,0 % (variant 2) under adopted duty conditions and evaluations of capital costs (Cic + Cin) with annual expenditure related (Ce+Co+Cm). The adopted duty conditions include daily and seasonal fluctuations of air flow. This was the reason for the adopted energy consumption as, kW∙h: 2158 (variant 1),1743...2201 (variant 2), 1058...1951 (variant 3). The article refers to Europump guide tables in order to simplify sophisticated factors search (Cp /Cn, df), which can be useful for economical analyses in Russia. Example of evaluations connected with energy-efficient solutions is given, but this reference involves the use of materials for the cases with resource savings, such as all types of fuel. In conclusion follows the assent to use LCC indicator jointly with the method of determining discounted cash flows, that will satisfy the investor’s need for interest source due to technical and economical comparisons.

Joint Application

The article is aimed at considering the content of information modeling of construction and investment projects through the joint application of BIM-technologies (Building Information Modeling - information modeling of buildings) for the full life cycle of construction objects. The use of this approach in the implementation of investment and construction projects makes it possible to detail the project in order to make timely decisions at every stage of the project life cycle, from the concept of a future facility to its operation.Building information modeling technologies make it possible to determine and increase the level of interaction between project participants and improve the organization of collaboration between all construction participants. This requires quantitative and qualitative transformations, including the transition to information modeling and in areas related to construction, which contribute to a more efficient allocation of investments and the formation of the optimal project cost, solving the problems of increasing construction volumes and implementing large-scale infrastructure projects in optimal terms at the state level. Determining the prerequisites and ways of implementing the BIM concept with the optimization of business processes is relevant and requires scientific substantiation and implementation of the study of information modeling technology in the educational process for a high-quality and professional approach to construction projects in practice.
