Cost benefit analysis of energy renovation and structural retrofitting of Tobačna Ljubljana factory building

摘要

The thesis presents design of energy renovation and structural retrofitting of the building of TobačnaudLjubljana factory. First, we have obtained the necessary information about the current state of object.udFor this purpose, we have also used infrared thermography and the heat flow meter. Images andudmeasurements, obtained by non-destructive techniques, were used as a part of input data for theudanalysis of building energy efficiency. In ArchiMAID program we created energy performanceudcertificate for our case study. It showed that energy efficiency of building is not adequate according toudcurrent code requirements. Further, we have analyzed different measures of energy renovation andudhave chosen the most optimal combination of measures by considering the protection of culturaludheritage. Building that have historical values do not necessarily need to achieve all requirements forudenergy efficiency. Therefore we upgraded the energy performance of building within the limitsudprovided by protection requirements. For the seismic assessment we have used FaMIVE analysis foruddetermination of relevant local failure mechanisms and with SREMB we verified storey response ofudthe structure. With appropriate measures we have increased seismic resistance of the building inudsignificant amount. Because the building is located on poor clay soft soils its seismic resistance canudnot match current code requirements. A rough cost estimation of various retrofitting measures hasudbeen done and the most optimal solution of retrofitting measures has been chosen. With cost benefitudanalysis, an optimal proposal was created for the retrofitting of the building that is based on theudsimultaneous execution of both works. We have showed that is possible to save around 9 % of theudtotal investment in the complete retrofitting.
