Casa SpA (public company property of Firenze Municipality) improved Energy monitoring in Florence’s new generation social housing buildings.
Casa SpA realized a new building entirely in wood in Viale Giannotti. The social house has 78 apartments with integrated design that develops since the preliminary phase of the project all the aspects: architectural, structural, energetic, plants, acoustic and economic. Instrumental verifications of the energetic performances of the building (both in winter and summer regime). To collect data are used Heat flow meter, Thermal camera, Thermo-hygrometer, Thermo-hygrometer - datalogger USB and sensors elaborated by the university of Firenze. hHas been carried forward Monitoring of heating consumption, Damp monitoring in wood structures, PV monitoring system. Each apartment is provided by an accounting plant to read the heating and water consumptions. On the perimeter walls 6 innovative tools have been installed, developed by the University of Florence, which allowed continuous monitoring of the heat flow through the walls with a triple degree of precision compared to the systems currently on the market and therefore to verify the energetic behavior of the structure of the building to vary the internal and external temperature and humidity conditions. On the top floor a technical room was set up where they were collected and processed the data coming from the various sensors in the field. A sophisticated monitoring system was installed in the building to control humidity of load-bearing wooden partitions in order to optimize use and maintenance of the building.

Resources needed

The resources needed were funds and human resources from the department of industrial engineering of the University of Firenze for approximately 30,000 euros.

Evidence of success

Maintaining a public housing in class A is not easy, but in this case the accuracy of the monitoring has made it possible to achieve the pre-set energy efficiency targets, also involving tenants. It should be emphasized that it is the first wooden housing company in Europe to have a monitoring system to control the humidity of the wooden bearing walls in order to optimize the use and maintenance of the building.Monitoring of this type plays an important role in the management of a structure.

Difficulties encountered

Other newly built or restructured public housing had very serious management problems, given that tenants did not have the tools of direct knowledge of energy consumption. In this case, having continuous and updated monitoring in real time has helped a great deal in the management of each apartment.

Potential for learning or transfer

In the Florentine experience a method has been applied that can be extended to larger realities; it should be emphasized that the monitoring takes place with instrumentation developed on its own by the University of Florence, which collaborated with full integration with Casa Spa. The method and the project can be replicated also thanks to the low investment costs, which have allowed a company entirely public to build and manage public housing that will also have low management costs thanks to continuously monitored energy efficiency. Given the type of tenants, who do not have great financial resources, the project meets energy efficiency requirements as well as social needs.
