The energy efficiency of a system and the performance level of its equipment and installations are the two key elements based on which the investment decision in its modernization is made. They are also very important for setting up optimal operation strategies. The energy audit is a well-known and worldwide recognized tool for calculating energy performance indicators and developing improvement measures. This paper is a synthesis of the energy audit results performed for a district heating network that uses geothermal energy as its primary source of energy. The location of the heating system is inside a university campus. The first part explains the necessity of a comprehensive study on district heating networks and introduces the defining elements that characterize the analyzed equipment and installations. The complex energy balance methodology that has been developed and applied to this district heating system is presented in the second part of the paper. Next, the methodology for collecting the input data for the energy and mass balance is explained. In the final part, the numerical values of the performance indicators and the technical measures that must be applied to improve energy efficiency are shown, and conclusions are drawn.

“…University campuses-as spaces for educational services-consist of specific groups of different type of buildings having a significant energy consumption [7]. Therefore, as an important measure of energy efficiency on university campuses, energy audits have been proven to be a topical issue [8][9][10][11][12][13][14][15][16].…”

“…The energy generated by the photovoltaic system of the Solar Energy Research Center of the UFSC has made it possible to satisfy the energy needs of the building with 13% of the generation and to have a surplus of 87% to be used as compensation for other consumer units of the same university, as can be seen in the work of (Zomer et al, 2017). As also shown in (Ruviaro et al, 2018), the economic feasibility study for the Federal University of Santa Maria (UFSM) shows a financial return obtained in about 6 years, also analyzing the possibility of adjusting demand contracts. Another study looks at the return on investment based on energy compensation for the North Wing UCSI University Campus in Malaysia, with a payback period of around 16 years, and compares it to another type of public policy-based incentive, "feed-in tariff", which would reduce the return on investment to around 11 years (Tan and Chow, 2016).…”

“…Economic incentives, which attract the attention of consumers from residential to commercial and industrial, aim to reduce electricity bills, as presented in (Ruviaro et al, 2018), allowing them to invest in other sectors of interest. This interest in incentives can also be seen in the increase in the number of connections from consumers in the A4 voltage group, for example, which almost tripled between 2019 and 2018 (ANEEL, 2020c).…”

The energy compensation system has attracted the interest of several sectors, including the public sector. In this context, this work presents a technical dimensioning and techno-economic feasibility of installing a photovoltaic generation plant, considering the service to a Brazilian public university campus. Four systems were designed using NREL's PVWatts and SAM tools with the NSRDB database, analyzing 6 economic viability situations. The results show a payback of 6 years and 3 months for a 545kWp system without energy storage and 10 years and 5 months for a 180kWp system with energy storage. The variations in the results depend on the implementation considerations of each of the proposed systems, such as the energy availability demand contract and the savings on the bill made possible by the implementation method.

“…The electrical energy distribution system of university campuses and the quality of energy on campuses is an important issue. In this context, various studies have been published on improving campus electrical energy infrastructure [8], harmonic analysis of campus energy distribution system [9]- [10], improving energy efficiency and reducing energy consumption on campuses [11].…”

In this study energy quality of university campus network have been analyzed experimentally. The experimental tests and measurements have been implemented at Engineering Building of the Bolu Abant Izzet Baysal University (Turkey). Energy quality analysis has been performed by making current, voltage, frequency, power factor, harmonics, neutral-earth voltage measurements at the main distribution board of the Engineering Building. Besides, active power filter has been connected and its effects examined. The reasons for the energy quality problems on the electric power distribution system of the campus building have been revealed and required solutions have been offered.
