G. Batechko, O. V. Shelimanova, S.V. Shostak ABSTRACT The relevance of increasing the energy efficiency in buildings of domestic higher educational institutions is determined not only by the need to save energy resources, but also by the fact that such “green campuses” can become the basis for the formation of an ecological and energy efficient lifestyle for today's youth. An integrated approach to the selection of energy-saving measures in a building requires the models of thermal comfort which take into account the intensity of human activity, the type of clothing, the speed of air movement in the room, relative humidity and the like. The purpose of this study is to improve the efficiency of the energy system of campus buildings by taking into account the interaction of energy sources, the heating system, the thermal properties of the enclosing structures and the standardized parameters of the indoor microclimate. Along with an integrated approach to the problem under study, taking into account the necessary comprehensive analysis of energy-saving measures in the system "heat source - enclosing structures - external parameters", attention should be paid to the indoor climate and the problem of meeting human needs for thermal comfort. With the help of a miniature temperature datalogger RC-1B, a round-the-clock monitoring of temperatures was carried out in some rooms of the educational building No. 8 of National University of Life and Environmental Sciences of Ukraine during the heating season. The analysis of the experimental data shows that despite the improvement of the thermal accumulative properties of the outer fencing of the building after the implementation of thermal modernization work, the temperatures in the room do not always correspond to the norm. Thus, when implementing energy-saving measures, it is impossible to violate the conditions of comfort in rooms in which thermal equilibrium is maintained in the human body and there is no tension in its thermoregulation system.

This article attempts to verify the relevance of building a network of energy knowledge hub centres to tackle the priority objective in enhancing energy efficiency and energy saving management in higher education institutions. It is emphasized that the issues of careful and wise use of fuels and energy resources challenge more government efforts, active use of advanced projects to manage energy saving and energy efficiency through the integrated use of different energy sources. The study argues that to identify the potential for energy saving, setting regulatory indicators of energy consumption, determining the key energy saving measures and target objects in the public sector where energy saving programs are planned to be implemented, there is a need to conduct energy surveys with further developing of energy passports for buildings. In the frameworks of this study, the following research methods were used: abstract and logical analysis – to interpret the essence of energy saving concepts for universities; systemic approach – to identify the specifics of energy saving projects implementation in universities; in-depth analysis and synthesis – to forecast the university development priority area of the "Energy efficiency and energy saving"; system, structural, comparative and statistical analyses – to assess the energy consumption in universities; economic and statistical methods – to evaluate the level and the dynamics of the energy sources use before and after the implementation of project activities; graph-based and analytical methods – to facilitate visual representation and schematic presentation of forecasts for further development of energy efficiency and energy saving systems. The study offers a mechanism to shape a network of energy knowledge hub centres to forecast a priority development area of energy efficiency and energy saving programs in higher education institutions along with providing an overview on the process of energy saving based on energy knowledge hub centres by carrying out the following tasks: project identification, scanning, energy audit, implementation of an action plan, and monitoring. It has been verified that to enhance the energy supply system in the university buildings, the following objectives should be attained: using the energy knowledge hub to forecast the university energy efficiency and energy saving programme, implementing an automated individual heating station with weather regulation and installing new radiator heaters.

The article reveals the essence of the key motivation drivers to save energy and increase the energy efficiency in higher education institutions. In particular, a low level of interest of higher education institutions in the implementation of strategies to reduce energy consumption has been observed. The findings suggest that the lack of interest in energy saving is primarily affected by budget legislation since the energy cost calculation was based on the consumption norms for a particular budgetary institution and the current (planned) electricity and heat tariffs. Recently, it has been decided that from now on universities will not obtain budget funding to cover utility costs; the amount of subsidies from the Ministry of Education and Science of Ukraine for the implementation of the government objectives will comprise regulatory costs for public service provision according to the student contingent. Standard property maintenance costs will not be covered by the Ministry anymore which will impose the burden of paying the utility bills upon the University’s gross income. Hence, there is a need to take efforts to enhance energy efficiency and energy saving in higher education institutions which was implemented using a foresight methodology. Within the scope of this study, the foresight project to improve the energy efficiency of buildings in the frameworks of the University energy hub is based on the following calculations: thermal energy consumption for heating public buildings, estimated hourly heating load to ensure heating in the building, verifying the feasibility of heating standby regulation, measuring energy savings through the creation of an automated heat supply station, as well as annual savings in monetary terms. In order to save resources and boost energy efficiency based on the University energy hub using an automated heat supply station, the study offers a mathematical toolkit to justify the choice of minimum and maximum values of optimal microclimate parameters; reduce infiltration, increase the efficiency of indoor air distribution; optimal modes of local air conditioning, preheating and cooling; utilizing of "waste" and natural heat and cold; "combining" microclimate systems with other systems; improving automation devices in technical systems. It is argued that increasing the energy efficiency of heating systems in University buildings on the basis of its own energy hub will contribute to gaining significant savings in thermal energy for heating and significantly reduce carbon dioxide emissions into the environment. In addition, the study reveals that the cost of thermal energy for heating depends upon a building design, modernization quality, reconstruction and insulation, applied building materials, spatial planning solutions, the presence or absence of control and automated systems, maintenance systems and attitude of owner’s attitude to innovations. The conclusions summarize that the cost of thermal energy can vary significantly in buildings of the same type.

The article is devoted to the analysis of information literacy programmes developed by libraries of higher education institutions in Hong Kong and Ukraine. The application of such theoretical and empirical methods as an analysis of sources, the method of external observation over the foreign and Ukrainian experience of the information literacy programmes developing, as well as a prognostic method for summarising, allowed to reveal similarities and differences in the content and forms of information literacy programmes implemented at Hong Kong and Ukrainian universities. Different stages of implementation of information literacy programmes by the Chinese University of Hong Kong (CUHK) Library during the last two decades are highlighted. The content of information literacy programmes provided by the libraries of 4 Ukrainian universities in general and the scientific library of the Kyiv National University of Culture and Arts (KNUCaA), in particular, is reviewed. It has been found out such similar characteristics of information literacy programmes of libraries that were analysed as using of traditional forms (lectures, practical exercises, instructions, video lessons) to form the skills and abilities for the effective information search, analytical processing, organisation, evaluation, and use of this information. It has been found out that, unlike Hong Kong, the introduction of certified and online information literacy courses by Ukrainian universities libraries is isolated cases. There is also no experience in testing students’ knowledge before studies of information literacy. Testing is usually done after completing the information literacy programmes, but these tests are not mandatory and only recommended. The authors hope that the experience of the CUHK Library (Hong Kong) in the implementation of the “Immersion Programme”, the UGCIL project, and InfoLit for U will be useful for the Ukrainian scientific library community, considering that libraries of higher education institutions in Ukraine have also started to develop similar programmes and modules. In particular, the interactive online guide “Music Documents in the KNUCaA Scientific Library” is an example of a modern approach to the formation of first-year students’ information literacy, their acquaintance with the scientific library, its services, and resources, basic types of documents, an electronic search algorithm.

Aims: To correlate the energy and carbon emission efficiency relative to research income, gross internal area, and population for all the Higher Education Institutions (HEIs) in the UK and to assess the comparative carbon emission efficiency of HEIs relative to economic metrics. Study Design:  Analytical panel data study. Place and Duration of Study: This paper evaluates the energy efficiency of 131 HEIs in the UK subdivided into Russell and non-Russell groups from 2008 to 2015. Methodology: Data Envelopment Analysis (DEA) and Malmquist productivity indexes (MPI) are used for the efficiency calculations. Results: The empirical results indicate that UK HEIs have relatively high energy efficiency scores of 96.9% and 77.6% (CRS) and 98.5%, 86.3% (VRS) for Russell and non-Russell groups respectively. Conclusion: The evidence from this study reveals that HEIs are not significantly suffering from scale effects, hence, an increase in energy efficiency of these institutions is feasible with the present operating scale but would need to work on their technical improvements in energy use. Malmquist index analysis confirms the lack of substantial technological innovation, which impedes their energy efficiency and productivity gain. Findings show that pure technical efficiency accounts for the annual efficiency obtained in the DEA model, the technological progress in contrast is the source of their energy inefficiency.

The Impact

Higher education institutions (HEIs) have a huge potential to save energy as they are significantly more energy-intensive in comparison with commercial offices and manufacturing premises. This paper provides an overview of the chief actions of sustainability and energy efficiency addressed by the University of Alcalá (Madrid, Spain). The policies implemented have shifted the University of Alcalá (UAH) to become the top-ranking university in Spain and one of the leading universities internationally on environmentally sustainable practices. The paper highlights two key elements. First, the actions adopted by the managerial teams, and second, the potential of public–private collaboration when considering different stakeholders. A descriptive study is developed through document analysis. The results show that energy consumption per user and energy consumption per area first fall and are then maintained, thereby contributing to meeting the objectives of the Spanish Government’s Action Plan for Energy Saving and Efficiency (2011–2020). Because of the research approach, the results cannot be generalized. However, the paper fulfils an identified need to study the impact of HEIs and their stakeholders on sustainable development through initiatives in saving energy on their campuses and highlights the role of HEIs as test laboratories for the introduction of innovations in this field (monitoring, sensing, and reporting, among others).
