In addition, the building fund of the UL consists of farm buildings and a magnificent building of the rectorate. The total annual energy consumption at the UL is ~ 70 GWh, which means ~ 5.5 Mio € of costs (including VAT) at annual level and ~ 20.000 t of CO2eq emissions (for 2016). The average specific use in the analyzed 25 buildings is 77 kWh / m2 per year for electricity and 117 kWh / m2 per year for heat. The average annual specific energy costs are 18 € / m2 and 102.9 € / MWh for electricity and 76.2 € / MWh for heat.
Based on the implementation measures from the “UL Energy Strategy”, UL developed the “UL Energy Concept” in 2014. In addition to the inventory of the state of energy use and the characteristics of UL buildings, the concept also includes commitments to reduce energy use in UL buildings. In 2015, a central energy information system (energy accounting) was established – in which all members of the UL are included, and the system is also the basis for the on-going acquisition of data on energy use (the basis for active energy management).
In the energy renovation of UL buildings, IRI UL works as an organizer (designing and managing potential interdisciplinary projects) – brings together UL experts in interdisciplinary teams (the principle of knowledge alliances) and builds new knowledge and additional competences in the field of sustainable energy by linking it with expert knowledge from the economy. comprehensive renovation of buildings.
With this vision, UL creates a concrete and feasible image in the field of energy sustainability in the future. This means that the UL has to set even more ambitious goals than the national and European strategy for achieving sustainable energy goals. UL buildings will be among the most efficient within the public sector building fund, as before 2020, UL will exceed European and national targets in the field of energy saving in buildings.
The basis for the energy concept of the UL is the already established methodology of local communities (municipalities), which according to the energy law must do so. Local energy concept (LEC- most UL buildings are located in the City of Ljubljana, which already has this document). UL is a legal entity that does not commit the law to the preparation of an energy concept. However, according to the Energy Regulation, the UL will report on its consumption and, in particular, because it is a major consumer, and by its operation, can serve as an example and demonstration of changes and, consequently, significantly influence the quality of the environment, it has decided to prepare its energy concept.
UEC contains basic records on energy use and emissions, defining the elements of the strategy, and assessing and predicting sources of finance: it is necessary to plan financially to implement a long-term strategy, including any necessary allocations and redistribution of UL budget funds, appropriate time frames and possible external sources of financing or co-financing (eg European and national energy renewal programs such as the Structural Funds, ELENA, EU support programs, subsidies from large energy service companies, public-private partnerships, etc.).
Quality expanded energy audits, implemented together with partners from the UL and industry, are the basis for efficient energy management at the UL, for the determination of measures for the renovation of buildings and the acquisition of a statutory energy certificate. The review takes into account the prescribed methodology, which is upgraded with (for example) measurements for better knowledge of the state of energy use in the building.
