Project first phase: objectives

To carry out the energy audits for selected university buildings and facilities: National Pedagogical Dragomanov University of Kiev - 12 buildings Lviv Polytechnic National University - 22 buildings and facilities Kharkiv Polytechnic Institute - 25 buildings and facilities Total: 59 buildings for 342,000 m²

Energy audits according to EU norms and standards EN 16247 and EN ISO 13790:2008

Energy audits used to define the scope of refurbishment works To increase the technical capacity and awareness on energy

efficiency issues To establish a feasible priority investment program

3

Identified problems from energy audits

Deferred maintenance Critical technical conditions:

Building fabric Heating systems Ventilation systems Electric/lighting systems

Low comfort level: Indoor air temperature Air quality

Low energy performance of buildings Energy tariffs likely to rise

Conclusions This is a major infrastructure project with long term horizon

30 years and more Highly recommended:

for a save use and operation of the buildings for suitable indoor climate For improving learning and teaching conditions cost 7-8 times less than new constructions

Beside energy efficiency measures additional budget has to be planned for structural and basic maintenance repairs

Energy savings help the business case At current condition payback period ~20 years

Fitting financial engineering and future increase in energy cost make the business case good: Acceptable payback time
