Abstract
Energy saving and energy efficiency in modern conditions are an imperative of a stable evolutionary stage in the development of the country’s investment and construction complex, while at the same time creating sustainable competitive advantages for both energy producers and its consumers when implementing a construction investment project. The use of digital technologies is postulated as one of the main resources of energy efficiency. The paper systematizes the resources and effects that are formed as a result of increasing the energy efficiency of construction projects in the agricultural sector. The paper substantiates the necessity and specifics of the information modeling technology application to increase the energy efficiency of objects, and also determines the results of the use of digital technologies, differentiating costs and effects.
Highlights
One of the main processes taking place in the global economic system is the transition to a digital economy in all sectors and fields of activity, including construction
Despite the effectiveness of the organizational innovations listed above as a way of creating a sustainable competitive advantage in the framework of increasing the energy efficiency of a project, building or enterprise, one should take into account a number of institutional problems arising from their initiation and implementation of issued recommendations, as well as the initiated increase in costs at the construction stage to eliminate deficiencies identified by experts, which, if relevant information were available, would be easier and less costly to implement at the design and pre-design studies of the project
The BIM model contains an excess of information for CFD/BEM, since energy modeling takes into account only the surfaces of the object, which affect heat transfer, and in CFD, the components of the model, which affect the air flow, are taken into account
Summary
One of the main processes taking place in the global economic system is the transition to a digital economy in all sectors and fields of activity, including construction. Based on the principle of fractality, the management system of the investment and construction complex in Russia reproduces the corresponding changes under the influence of external fluctuations, both on the basis of self-organization of the digitalization process of construction and on the basis of initiated changes at the macro level of management. Energy efficiency as a competitive advantage is formed at three stages: resource (due to available energy resources, instrument metering and a certain level of energy consumption), investment (due to the development of energy audit, alternative energy) and innovative (through the implementation of product, process and organizational innovations, including digital energy modeling, innovations to minimize energy intensity, life cycle contracts and energy service contacts, and so on)
