Energieffektivisering av kulturbyggnaden Biotopia : Modellering av en byggnad med simulerade energieffektiviseringsåtgärder där kulturvärden ska bevaras

The purpose of this project was to examine how the cultural heritage building Biotopia can optimize its energy usage with 40 % by implementing different measures, without affecting the cultural values of the building. Furthermore, an economical evaluation has been done, to ensure that the measures are a reasonable investment. The project was done by the request of the property owners Ihus and STUNS Energy. To accomplish this the properties energy usage and production was modelled in the software VIP-Energy and PV*SOL. A literature study was also done to research the possible and allowed actions to implement. The measures that were found to be suitable was to install an extra window pane in the old windows, to add additional insulation to the attic and basement level of the extra building Konservatorbostaden and to install solar panels on a parking slot or alternatively on the modern additional building. Additional insulation of the facade was also modeled to visualize future possibilities if new techniques are found or if the current regulations change. The results showed an energy saving of 32 % if the allowed actions are taken and 56 % if the facade is insulated and the windows are completely renewed. All the measures that are allowed to be taken to energy optimize the building was found to be economically viable. The solar installations were found to be reasonable to implement on the parking slot or the modern additional building, provided that it is legally allowed
