Carregant

ENERPAT (Energy Planning Assessment Tool), is an application that enables professionals in the building sector (architects, urban planners, builders, technicians and municipal managers) to assess the state of the residential building stock and define rehabilitation strategies to improve the energy efficiency of the buildings.

The application integrates the data obtained from the Energy Performance Certificates provided by the Catalan Institute of Energy (ICAEN), the cadastre and the census sections, together with geographic information. The rehabilitation measures are based on the ICAEN simulation tool and the “Long-term strategy for energy rehabilitation in the building sector in Spain” (ERESEE 2014).

In the tutorial you can find a detailed description on how to use the application.

* The data provided by the ICAEN and the AHC was last updated in October 2017.

Benvingut als escenaris de rehabilitació

Per poder oferir-te estratègies de rehabilitació, ENER_Plan ha agrupat tots els edificis de l’àmbit per paquets de característiques similars.

Abans d'accedir al Pas 3 cal saber que:
  1. En la part superior es plantegen objectius de rehabilitació per escollir els del teu interès.
  2. Primerament, s'agrupen tots els edificis de l'àmbit per paquets de característiques similars. **
  3. Posteriorment, apareix informació agrupada en vertical de cada paquet d'edificis.
  4. A la part esquerra dels paquets d'edificis apareix la informació que representa el total d'edificis de l'àmbit.
  5. A la part inferior veuràs un resum de l'abast de la rehabilitació on pots decidir el percentatge d'edificis a rehabilitar.

**ENERSI utilitza les dades de la certificació per agrupar els edificis de l’àmbit seleccionat per paquets de característiques constructives similars segons nombre de plantes, ús i any de construcció. Els Paquets d’edificis estan basats en les agrupacions d’edificis per clústers de l’Estratègia a llarg termini per a la Rehabilitació energètica en el sector de l'edificació a Espanya publicada pel Ministeri de foment.

ENERSI has grouped the buildings of the municipality with similar characteristics into nine clusters (CL). This table contains information about the energy efficiency of the buildings included in each cluster.

INTERVENTIONS


Cluster nº 1

Cluster of single-family buildings built before 1950 with 1 to 3 floors. They are considered buildings built with traditional systems of solid and thick walls, predominating the sloping roof with ventilated chamber and with the levelling floor in contact with the ground.
