Proyecto Teenergy escuelas

Escuelas de alta eficiencia energética en el Mediterráneo

 
Se basa en una Multi-plataforma usada como una red interactiva para la gestión de reglamentos técnicos, y tecnologías, que sirva como base de datos y para la difusión de buenas prácticas.


Teenergy Escuelas establecerá un plan de acción y una estrategia común basada en la experimentación de: técnicas de ahorro de energía, la integración de materiales innovadores y las energías renovables (refrigeración pasiva) para reducir los costes y el consumo. Además, el proyecto establecerá un punto de referencia de buenas prácticas basadas en datos de 50 Auditorias Energéticas en varias zonas del Mediterráneo, que proporcionará valores representativos y comparará el rendimiento en el uso de la energía de las escuelas de secundaria.


El proyecto funcionará en cuatro países importantes del Mediterráneo, por las organizaciones participantes representan a ocho territorios diferentes y dentro de los mismos se estudiarán distintas condiciones climáticas típicas que se refieren a la costa, montaña y ciudad: Provincia de Lucca y Trapani (Toscana, Sicilia - Italia), distritos de Pafos y Larnaca (Chipre), Provincia de Atenas (Municipio de Kessariani) a través de las acciones de la Prefectura de Atenas (Ática) y la provincia de Pieria (Municipio de Katerini, Macedonia Central) a través de la Universidad de Atenas (Grecia), Diputación de Granada (España).

 

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.
