An innovative approach of energy requalification: use of community funds (EEEF) and application of Energy Performance Contract for the Ducal Palace, headquarters of the Military Academy of Modena
Modena, Emilia-Romagna, Italy
The building was built in 1291, but the current architectural appearance was conferred by the architect Avanzini in 1634. State-owned, with a restriction of scientific restoration, it is currently the headquarters of the Military Academy. The palace hosts several use destinations with different energy needs: is equipped with a centralized system for heating and domestic hot water with generation system from traditional boilers, the distribution system has pipes with non-existent or deteriorated insulation, emission system with old cast iron radiators, climatic and manual regulation. The thermal dispersions of the building envelope are high due to the obsolete and inefficient type of windows and the opaque non-thermally insulated structures with deteriorated plasters. An economic obstacle to the possibility of intervention is the scarcity of funds available to the property. From the technical point of view, the obstacle is constituted by the inadequacy of the normally used calculation tools based on a static model to correctly predict the behaviour of the building.
Benefits
The intervention on the structures allows the reduction of the need for heating, with direct economic benefit. The new plant equipment will allow to adapt the indoor climate to the different needs of use of the various areas in which the building is articulated. The installation of a cogeneration system favours the self-consumption of electricity
The setting up of the contract according to the EPC model allows the best management of technical-economic risk and the availability of low-cost public financing favours the participation of private capital thanks to the reduction of financial risk
