although there are huge savings regarding energy consumption, it is not enough and
further actions should be taken.
It is heavy for the university to pay 20% of its budget to energy expenses reducing
the allocated budget to other factors such as laboratories (equipment, staff, dormitories, etc.), students’ ultimately needs and amenities, renovation of existing facilities,
etc.
The results of the calculation of the annual energy cost per student are presented
in Table 3 and Fig. 7.
