Smart UrbaN ServIces for Higher eNergy Efficiency

Scenario 1 Wide-scale assessment of heating energy needs

for residential buildings

Scenario 2 Building energy awareness tools to support

efficient management of heating/cooling systems

Scenario 3 Remote monitoring and control of public lighting systems

to support a more energy efficient management

Scenario 1 Wide-scale assessment of heating energy needs

for residential buildings

L’idea… • Stime dettagliate disponibili solo per un insieme ristretto di edifici/unità

immobiliari • Obiettivo è una stima semplificata, che possa essere applicata a

grande scala, basandosi sui dati di base e disponibili pubblicamente – Footprints, heights, construction periods…

– Building construction typologies…

L’obiettivo… • Fornire strumenti di monitoraggio, stima e pianificazione per gli

amministratori pubblici relativi al consumo energetico di edifici

residenziali su scala cittadina.

In tutta Europa i certificati

energetici riguardano una

piccola fetta dello stock edilizio.

In Italia, nel 2014, solo il 6% delle

unità immobiliari aveva un APE

3,6 milioni di APE/ACE emessi a dicembre 2014 (http://www.cti2000.eu/rapporto-ce-2014/)

59 milioni di unità immobiliari censite al 2011 (A, B, C, D, E) (http://wwwt.agenziaentrate.gov.it/mt/comunicazione/Gli%20immobili%20in%20Italia%202011/Gli%20immobili%20in%20Italia%202011%20-%20capitolo%201.pdf)

Rapporto 2014 - Attuazione della certificazione energetica degli edifici in Italia http://www.cti2000.eu/rapporto-ce-2014/

In Emilia-Romagna gli APE/ACE

a fine 2014 erano

595.389

- 84% residenziale

- 16% altri settori

Dati geografici in numeri

Db topografico regionale - circa 30 milioni di oggetti geografici

- quasi 1,8 milioni di edifici

- tutti gli oggetti gestiti con profondità storica

Db catastale - 15 milioni di unità immobiliari

- 5,5 milioni di proprietari (5 fisici, 0,5 legali)

- 46 milioni di relazioni proprietari-proprietà

Heating energy need estimation

Set of software modules for:

1. Model/import open geodata on spatial db – GeoUML Catalogue, PostGIS, QGIS

2. Verify completeness/correctness (app) – PhoneGap

3. Compute energy needs – WPS

4. Visualize / simulate / validate – Cesium

Footprint, superfici, numero UIU, usi

databese topografico, db catastale, ACI

Consumo gas / elettricità

Servizio SIATEL (Ag.Entrate)

Età, altezza (osservazione e

misurazione sul campo)

EP, trasmittanza e altre proprietà da SACE

e/o stima da dati tipologici (TABULA)
