| ^Long description | | ^Long description | **1.The characteristics and dimensions of the Versilia Hospital** \\ The new building, with the type of linear hospital with a compact structure, is spread over four floors above ground and two underground areas reserved for parking and services, and has its own kitchen and sterilization center. \\ On the ground floor the main entrance welcomes the visitor in a large and bright hall; on the first floor are the shops, offices and the outpatient area. The inpatient areas are located on the second and third floors. Ten operating rooms (certified and validated annually, as well as special rooms, according to the ISPESL guidelines and the UNI 14644 standards). The beds are about 450, including beds on a daily basis. \\ The Hospital is fully air-conditioned (heated volume 189.420 mc, the one cooled 135.440 m3) and is equipped with state-of-the-art technological and health facilities. \\ The total area of the area is about 11 hectares with a surface area of about 25,000 square meters and a useful area of the entire building of 69,000 square meters excluding parking. \\ A second project objective was to limit the height of the hospital (17.50 ml) below the pine tree crown (19.00 ml) of the frontal pine wood. \\ 1. The primary source of savings is the energy efficiency of the building structure and of the construction materials \\ In the approach to the rational use of energy, it should be noted that the technical and logical assumption of any intervention can not be separated from the verification and calculation of energy performance – energy efficiency or the energy performance of each building and the relative preparation of the certification energy of the building. \\ This assessment indicates the annual quantity of energy needed in each building to meet the needs of comfort, this quantity takes into account the characteristics of the building and especially its ability not to disperse the energy released by the winter and summer air conditioning systems, in essence the energy needs. \\ The first step for any good energy saving practice is to reduce the needs and therefore to contain as much as possible what is produced within each building. \\ The implementation of interventions that improve and qualify the insulation of buildings and allow not to disperse the energy produced is the most significant and lasting structural intervention for energy saving because it drastically reduces the needs and maximizes the effect of the inclusion of renewable sources in energy production.\\ With this kind of approach during the design of the "Versilia" hospital, and even more during its construction phases, we have implemented some predispositions that, beyond the peculiarities of the area, can also assume a general value in the realization of new hospitals or in the reorganization and restructuring of existing ones: \\ THE ORIENTATION OF THE BUILDING ACCORDING TO THE EAST - WEST AXIS \\ \\ THE WALL MADE UP OF TREES LIKE A CURTAIN WITH SOLAR IRRADIATION \\ \\ ATTENTION TO BUILDING MATERIALS TO ENHANCE THE INCREASE IN THE BUILDING ENVIRONMENT: \\ Ventilated walls in the external part Insulation in the inner courts Inverted roof isolated and ventilated Thermal break windows \\ Green cover of the warehouses \\ Screening films on the large glazed surfaces \\ \\ MITIGATION OF SOLAR IRRITATION WITH FINISHING SYSTEMS BUILDING (brise-soleil on the glass façades - blackout slats in the chamber glass) \\ \\ The recent regulations approved (2005 - 2007) and the implementation regulations in progress make it possible to have the technical references for the production of analyzes and instruments that allow to carry out the technical checks that can attest to the energy efficiency of the building, providing, moreover, the constructive indications to carry out the improvement interventions. \\ A very important objective would be the drafting for all existing hospitals of the energy certification or, in the absence of the ministerial guidelines, of the certificate of energy qualification, as a vade-mecum for the interventions to reduce the energy needs of the sanitary buildings. \\ \\ **2. A balanced choice of the "Plant Strategy"** \\ \\ The history of hospital heating systems is characterized by oversized steam boilers, large steam distribution pipes and scalding heaters. An energetic madness ! \\ To this choice we must now replace a different complexity of plant engineering solutions that will be able to meet the complex and diversified needs of a hospital building that, despite being in operation 24 hours a day and 365 days a year, presents functions that have specific needs. and different times and therefore articulated energy needs. In looking for a modulation in the different phases (summer - winter) and in the daily oscillations, our choice for the "Versilia" Hospital fell on this system. \\ 2 Low temperature hot water generators: 3.48 MW (modulating burners) + 1 0.90 MW condensing generator \\ 1 Alternating motor cogenerator P: 1,000 kWel - 1.140 kWter \\ 3 Water chillers with centrifugal compressor.

| | ^Abstract or Summary| Casa SpA (public company property of Firenze Municipality) improved Energy monitoring in Florence’s new generation social housing buildings. \\ Evidence of success \\ Monitoring confirmed the design parameters of the building, which reached class A. In Italy there are not many buildings in social housing that reach energy efficiency targets. \\ \\ 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. ||| |

| | ^Long description |Casa SpA, in cooperation with the University of Firenze, used the following working method in the interventions of realization of new buildings and recovery of existing buildings: Integrated design that develops since the preliminary phase of the project all the aspects: architectural, structural, energetic, plants, acoustic and economic.Design theoretical energetic evaluation in static regime (calculations according to UNI/TS 11300).Procedure for the adjudication of the public competition, with a call of tender with the criterion of the more advantageous economical offer.Supervision of works. Draft of the Certificate of Energetic Performance, done by independent technicians according to the building realization and its components, according to the national laws. Instrumental verifications of the energetic performances of the buildings (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. The data were collected from the Social Houses in Firenze, Viale Giannotti. In each house was made an energy audit. Then, has 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. ||| |
