Home Our News CETA Study visit to Cultural Heritage Rural Complex

In the ambit of the first “Energy Days” of the GovernEE project, CETA organized a study visit to the rural complex “Santa Giustina” at Marignana, in the Municipality of Sesto al Reghena (Province of Pordenone, Italy) The study visit took place on 15th June 2012 with the participation of representatives of different municipalities and public administrators.

The rural complex is a property of ATER of Pordenone (i.e. ATER is the public territorial body for the council houses that means the body which manage the social housing with the public funds support). The rural complex dates back to late 1400, even if the orientation of the complex could be addressed to the Romanian structures. Also some frescos are present in the main building (i.e. the master’s house); there are also some buildings for agricultural use, a smaller building called “Pesa”, more recent, and other structures. The degree of conservation was sufficient for recovery. Since 2007 the complex’s different buildings are partially managed under protection of the Cultural Heritage Office. In 2008 ATER bought the complex and presented a renovation project. The building benefited of retrofitting with an intervention based on the criteria of energy efficiency. Now it is used as a public residential building. CETA decided to organize the visit at the Complex of “Santa Giustina” because of the interesting renovation works taking into account energy efficiency considerations which ended by the restoration of 16 lodgings of public council houses.

 

 

For the realisation of the lodgings major issues had to be considered. First of all, energy saving. Starting from the assumption that the cleaner the energy, the less energy spared, higher attention has been directed to the building’s envelope which has been restored in order to obtain lower energy consumption index to the legal measurements. Seismic security was another point of view to be taken into account: even if the building was constrained by its protected status, the adaptation of the complex to the binding legislation on seismic risks had to be carried out. Last but not least, hydro-geological security had to be looking into. The intervention has been preceded by important analysis of the existent structures, including an accurate geological investigation of the building. The project’s economical feasibility was also considered since all reported issues have been faced by taking into consideration the financial factor, trying to realize the intervention by reference to the commonly directed budget allocations for such interventions.

During the first Energy Days, CETA organized workshop presentations at the Municipality of Sesto al Reghena. In this ambit Dr. Coassin, Town Councillor, introduced the event while Dr. Bello, Director of ATER, reported the importance of the intervention in Marignana, as an outstanding example of the preservation of old buildings. By transforming these into residential buildings, the terrain is no longer solicited for new constructions. CETA members presented the GovernEE project and the programme of the Energy Days before the visit. Two architects of ATER, Arch. Da Pieve and Arch. Liut, designers and planners of the intervention, presented in detail the characteristics of the historic building, the aspects that should be taken into consideration, the techniques used for the renovation and retrofitting, the final economic balance and the new energy efficiency class. At the end of the session, the visit started in the complex.

The intervention foresaw samplings on the plasters, on other materials, thermo-graphic analyses, structural analyses of walls and wooden beam floors, etc. The envelope insulation was done in the internal walls with mineral wools, wallboard and air bricks. A unique thermal plant was installed for all lodgings supplied with natural gas, but there are also thermal solar panels. The intervention allows getting an average of 54.04 KWh/m2/year. The better performing apartments belong to an energy efficiency class “B”. The building recovery was carried out in parallel with the artistic recovery (art. 10 of the Decree 42/2004 on protected sites). The Master house bear 6 lodgings, the agricultural building 10 and another open building has 16 boxes for cars emplacements, and there are also two pedestrian entrances. The interventions were carried out with the observation of criteria of good knowledge of the site under reconstruction (multidisciplinary criteria), of high technologies used for the investigation and of good materials & technologies of the intervention.
