BACKGROUND AND OBJECTIVES. Modern university buildings use a large number of resources, such as heat, cold and hot water, as well as electricity, which is the main consumed energy resource and is used for lighting, office equipment, ventilation and air conditioning systems. In order to improve the energy efficiency of university buildings, it is necessary to carry out heat and energy modernization of internal and external envelopes, which will allow for internal billing and qualitative analysis of consumption, which contribute to prompt decision-making on heat and energy modernization of the premises.METHODS. To assess the potential for improving the energy efficiency of buildings by improving the quality of protective structures, methods for assessing the temperature and humidity conditions of multilayered enclosing structures in a wide range of humidity under stationary boundary conditions were developed on the basis of the University Hub of Knowledge.FINDINGS. On the basis of the University Hub of Knowledge, Kyiv National University of Technologies and Design, the moisture content profile was calculated for the general estimation of the moisture condition for building No. 4, the planes of the highest moisture content were determined to find the most dangerous, from the moisture condition point of view, section of the structure, the calculation of the enclosing structure modernization according to the maximum allowable moisture condition for the analysis of moisture accumulation in the coldest month of the year was made.CONCLUSION. The advantage of the proposed method of increasing the energy efficiency of buildings by improving the quality of protective structures based on the University Hub of Knowledge is the possibility of calculation in a wide range of moisture content of materials, including supersorption moisture zone, as well as applicability to structures with multizone condensation of moisture. The clarity and simplicity of the proposed method makes it available for the practical implementation of energy efficiency improvements in all university buildings.

University Training

Energy efficiency in buildings is one of the main challenges in EU policy, since it is difficult to find common strategies and policies among Member States.  This article describes the USE Efficiency project, an initiative to create a common training framework for energy efficiency systems in buildings based on the Energy Performance Building Directive (EPBD), through university actions. Universities and students are proposed as shining examples both for energy efficiency solutions and for energy efficiency behaviour.  Moreover, involving university students guarantees acting on closest future market players and most convincing actor in diffusion of public opinions. The project aims to improve energy efficiency in university buildings and to establish training program for students around European countries.  In fact, this activity involves 9 Universities (Technology Faculties and Faculties of Engineering) and 4 technological and market players from widespread countries in EU.Initially, a mapping of the methodologies used for evaluating energy efficiency at the different countries is carried out. Students are trained in energy efficiency methods and strategies, having real work experience implementing these Energy Performance Assessment (EPA) methodologies in their own buildings. The wide geographical coverage of the consortium allows an important crossover of methodologies to achieve technical results even to a professional and technological level. Then, the analysed buildings at each university are monitored in order to collect data, which are then used to plan solutions to improve energy performance of the university buildings. This paper describes this innovative training initiative, which involves students as main actors, working and interacting together with professors and technicians in order to improve energy efficiency in their educational centres.

As Malaysia continues to focus its efforts on becoming an education hub, universities are vital places where learning processes, teaching and research activities are conducted. A university is a factor of production in producing graduates, and the university buildings are considered to be assets and resources. Hence, to prolong a university building lifecycle to ensure all university activities continue performing at an optimum level, building maintenance management is vital. Despite the fact that several previous studies have been conducted in this area, there continues to be maintenance issues surrounding university buildings. The maintenance of university buildings has always been viewed as an insignificant activity. Therefore, the objective of this paper was to critically review key factors that affected maintenance costs of university buildings, and consequently propose different approaches to resolve this issue. The present paper reviewed related literature from previous studies and publications. As a result of the comprehensive review, it was identified that key factors that affected university building maintenance costs were fund allocations allocated by university management teams for maintenance departments, user behaviours, environmental factors, university design complexities and the quality of components and materials of university buildings. Each factor identified was critically examined and addressed to ensure that university buildings would be well-maintained.

Moisture content and water activity are important parameters for quality characterizationof products like bulk materials, powders, granules. Thus, an exact determination is necessarilyrequired in a wide range of industrial applications. Moisture of materials is the content ofnon-chemically bound water in a solid or liquid. Water activity (aw) is a characteristic/parameter ofthe non-chemically bound (“free”) water in materials and is measured as humidity over asolid/liquid surface at constant temperature (equilibrium moisture content). It is an importantparameter to characterize the quality of e.g., pharmaceutical and food products. In ourcontribution, we present the developed MOISHUM device for staged determination of wateractivity and moisture content of liquid and solid materials.

Chinese rolls are prepared from hot water dough and wrapped with meat and vegetable when consumption. Staling of Chinese rolls results in loss in texture and eating quality. Moisture content, enthalpy change (H), texture and sensory quality of Chinese rolls which are significantly affected during staling at 4°C storage, were monitored over a storage period of four days. Moisture content was founded to decrease steadily during staling of Chinese rolls. Enthalpy change, H, as measured by DSC increased with storage time. The texture of Chinese rolls became progressively harder with storage at 4°C. A decrease in sensory quality and acceptability of the Chinese rolls was observed with storage. Most of the staling parameters show good correlation. Texture showed the best overall correlation with all other staling parameters.

The Impact

The COVID-19 pandemic has caused chaos in many sectors and industries. In the energy sector, the demand has fallen drastically during the first quarter of 2020. The University of Almeria campus also declined the energy consumption in 2020, and through this study, we aimed to measure the impact of closing the campus on the energy use of its different facilities. We built our analysis based upon the dataset collected during the year 2020 and previous years; the patterns evolution through time allowed us to better understand the energy performance of each facility during this exceptional year. We rearranged the university buildings into categories, and all the categories reduced their electricity consumption share in comparison with the previous year of 2019. Furthermore, the portfolio of categories presented a wide range of ratios that varied from 56% to 98%, the library category was found to be the most influenced, and the research category was found to be the least influenced. This opened questions like why some facilities were influenced more than others? What can we do to reduce the energy use even more when the facilities are closed? The university buildings presented diverse structures that revealed differences in energy performance, which explained why the impact of such an event (COVID-19 pandemic) is not necessarily relevant to have equivalent variations. Nevertheless, some management deficiencies were detected, and some energy savings measures were proposed to achieve a minimum waste of energy.

Sustainability has been increasingly incorporated as an essential life perspective into educational institutions as well as local communities. Universities play an important role into the society by debating theoretical contributions and implementing concrete actions. The present research was developed to evaluate a university’s energy efficiency by using the Polytechnic University of Catalonia, Spain as a reference for University of Passo Fundo, Brazil. The reference values and index ratings obtained for energy performance, in the Universities’ building stock, were evaluated based on positive and negative features. The study identifies and assesses the evolution of incident factors towards energy consumption and its impacts on the hidropower generation, the main energy resource in Brazilian. Hence, the university can promote a reflection about its practices to develop feasible tools that contribute to sustainable measures. As a result, guidelines and strategies were proposed, not only on targeted evaluated buildings but also on the entire building stock. The research indicates the importance to follow well-defined guidelines in the decision-making process by institutions of higher education, in order to consider integrated sustainable practices. The methodology and findings contribute to improve and promote Education for Sustainability, which should encourage other similar universities to put sustainable projects into practice and encourage the whole society to face the inevitable change of paradigms for achieving the Sustainable Development Goals (SDGs).

The licuri nut shell is a potential source of biomass for energy production. The aim of this study was the physicochemical characterization of the licuri shell, focusing on the increase of its use as a fuel. The material was collected in Caldeirão Grande-BA and the characterization included a wide range of analyses such as: moisture content, bulk density, particle size distribution, ash content, volatile matter, fixed carbon, high heating value (HHV), hot water and cyclohexane/ethanol extractions, Klason lignin content, and thermogravimetric analysis (TGA). The obtained results  were: moisture content (11,1%), HHV (4652 kcal.kg-1), Klason lignin content (36,86%), volatile content (74,91%), and fixed carbon (21,19%). The results showed that the material can be considered suitable for the purpose of generating energy when compared with other types of biomasses. The ash content (3,9%) and the extractives content (46,75%) are in accordance with the values observed for the babassu nut shell, Brazilian nut shell, and coconut. Finally, by the TGA analysis, it was observed that the degradation peak occurred at 272°C with a loss of 65% of weight. With these results, the licuri nut shell has shown to be potentially promising for the energy production.
