ENERGY MANAGEMENT ACCORDING TO ISO 50001

Purpose of seminar • Energy management – legal obligation and response to an increasing need for

reduction of energy costs

• Legal obligation in place in public sector in Croatia

• Private sector players who already have a system in place will have benefits

• The approach based on HRN EN ISO 50001:2012 enables energy costs management in a long term manner and reduce them with the optimal ratio between investment and achieved.

• The seminar enables monitoring energy costs in public sector, industry, small

and big enterprise, energy suppliers etc..
