WP1: Transnational tool for energy audit of public buildings

The main aim of WPT1 is to develop 3D building models and a methodology to perform a comprehensive analysis of energy audits and consequently visualize them in order increase energy efficiency in public buildings.

Building upon a review of what is known and had been done so far in past projects, the methodology illustrates the entire data pipeline and supports the assessment of energy performance in public buildings especially in urban areas and to visually deliver that information in an easy-to-understand language making energy data accessible to non-experts, engaging local users. Management & monitoring energy flows in public buildings both in a spatial and a temporal dimension supports local authorities in EE actions and increases public awareness through public access to the energy consumption data at the same time.

To achieve these objectives the project adopts the following activities:

• develops a spatial database focusing on energy consumption (from municipalities databases and surveys) and geospatial data from existing repositories among the project and associated partners;
• generates 3D building models in urban areas using available geospatial data with sufficient levels of detail;
• estimates PV potential, energy flows and heating losses using 3D geometries and energy data, highlighting problematic areas such as windows or roofs;
• elaborates the transnational methodology to collect energy information and their visualization using 3D building models to establishing the replicability of the project results.

The 3D building models will be created in this WP and will be adopted in WP2 and later as pilot actions in the WP3. Local public authorities and key target groups will support and validate the results.

The partnership is happy to share the following results:
