Teenergy Schools Project

 

Sistemi ad alta efficienza energetica per le scuole del Mediterraneo

Piattaforma multi-canale utilizzata come un Network interattivo per la gestione della normativa tecnica, la creazione di un data base di tecnologie energetiche e la disseminazione di best practice.

Edifici Scolastici ad alta efficienza energetica nell’area Mediterranea: Piattaforma multi-scala come Rete interattiva per la gestione di regolamenti tecnici, banca dati, best practice e attività di disseminazione. Teenergy Schools svilupperà un Action Plan e una Strategia Comune basata sulla sperimentazione di: tecnologie di risparmio energetico, integrazione di materiali innovativi e di energie rinnovabili ( sistemi di raffrescamento passivo) per la riduzione dei costi e dei consumi. Inoltre il progetto mira a realizzare un monitoraggio esemplare attraverso energy audit nell’area MED in modo da ottenere valori rappresentativi e paragonabili delle prestazioni energetiche degli edifici scolastici.

Il progetto opera in quattro paesi importanti dell’area MED, includendo istituzioniche rappresentano otto diversi territori e le tre condizioni climatiche tipiche che si riferiscono alla costa, alla montagna e alla città: Province di Lucca e Trapani (Toscana, Sicilia - Italia), Distretti di Paphos e Larnaca (Cypro), Provincia di Atene (Municipialità di Kessariani) attraverso le azioni della Prefettura di Atene (Attica) e la Provincia di Pieria (Municipialità di Katerini, Macedonia centrale ) attraverso l’Università di Atene (Grecia), Provincia di Granada (Spagna).

 



The energy envelope for a school buildings. The new building for Majorana High School

 

The new building for Majorana High School has been developed with the aim of spreading sustainable construction methodology in Italy. The European Union established these regulation through the Energy Performance Building 2002/91/CE and EU Directive 2010/31. These aim to diffuse local and national regulations to guarantee high the efficient buildings, using appropriate policies which consider local climate conditions. From 31st December 2018, we must start building zero energy public buildings.

The reduction of energy consumptions and the attention to environmental requirements are the main objectives of the Majorana Hig School Project. The design concept of the building has been characterized by the adoption of solutions to improve solar gains and natural ventilation. During the stage of design we simulated every energy performance of the building, choosing the systems that can to reduce energy consumptions. During the first design stage we employed an energy concept which corresponded to the features of the functional plan, the site, the local conditions weather and climate. On the basis of those parameters, the shape and consequently the structure were defined. 

The construction of the new school building involved energy efficient measures, which are not only current innovations for the actual state of art but are also replicable in other schools in Italy.

The importance of this project is the introduction of some specific, innovative, energy saving techniques, which set new energy, environmental and health standards for school buildings. In this framework, the following measures have been incorporated:

  • An appropriate orientation of the building and envelope design.
  • Ventilated façades and highly insulated building.
  • Use of natural ventilation thought a good design.
  • Use of light shelf for even distribution of daylight.
  • Use of a radiant floor for heating.
  • Integration of renewable energies, in the form of photovoltaic and solar thermal panels in the roof.
  • Design buildings with a compact volume to reduce the surface of the envelope and the thermal bridges.

Build walls with a good thermal inertiaThe envelope of the school buildings should be thought as a "skin", a dynamic environmental philtre, that can regulate the airflows, the solar radiation, the heat flows and the water vapour. The skin of the building became a technological system that can produce thermal and electric energy that will be possible to use for the metabolism of the building.

 

The school buildings, in the Mediterranean area, have the major problems with high temperature and indoor discomfort in intermediate months (April, May, September and October), when in the schools is not active a cooling or heating systems. Therefore is very important to develop in the school buildings sustainable technology for the envelope with a good thermal inertia so to decrease the indoor temperature and assure the good indoor comfort.
