METHODOLOGY AND SELECTION CRITERIA IN SEEP TECHNICAL IMPROVEMENTS

1 “Preliminary Energy Audits” prepared by SEEA trained energy auditors – visiting nominated buildings, determining current situation, suggestion of potential ee measures to be implemented, selection of optimal package of ee measures according to investment and pay-back and estimation of preliminary investment ee package 2 Ranking buildings according to preliminary investment and pay –back value 3 List of selected buildings, i.e. “scope of the Project”, made by line ministries 4 Based on the scope of the Project, Technical Consultant (TC) is selected for design, producing bidding documents, supervision and for monitoring “before” and “after” implementation of ee measures

5 Based on 1, visits to schools and coordination with schools administrators and local authorities, TC recomends acceptance or revision of the originally proposed energy saving measures and makes “Evaluation Reports” for each school with suggestion of measures package and estimation of investment costs 6 Monitoring “Before” 7 Procurement procedure and selection of Contractor for works 8 Monitoring “After” and preparation of “Final Report”

21 EE Measures savings 40% the most effective measures 1 Replacement of windows and doors 2 Thermal insulation of façade walls 3 Attic insulation 4 Hydro and thermal flat roof insulation 5 Repair works and thermal insulation of (pitched)roof covering 6 Installation of thermostatic valves with balancing combining 1 to 6 INVESTMENT PACKAGES A, B, C… 1 Investment 2 Pay back = Investment / Energy costs

Selection Criteria Preliminary investment cca EUR – School Evaluation Report: New Boiler house = One School more Preliminary investment cca EUR – School in Pozega Thermal insulation of roof needs roof reconstruction: EUR Increases preliminary costs 55% End Users Request: “Jarane, nemoj mi šminkat fasadu, krov ti meni popravi!” Translation: “Listen, my friend, do not paint walls, I do not know what to do with damaged roof!” But roof reconstruction is not ee measure...
