It is a GIS application based on the Internet that contains the solar potential of the Bressanone buildings' roofs.

I Description of the measure

Title in original language: Catasto Solare Città di Bressanone

Location of CNA: Italy

Municipality / regional entity: Municipality of Bressanone/Brixen

Category of the experience: Strategy
Type(s) of CNA:

Principal nomination: Technological

Thematic field(s):

Principal field: Energy 
Secondary field(s): Land use, Industry & services

Spatial scale: Local
Time & duration:

Start date: 2011
Duration: unlimited

Key word(s): buidings, city, photovoltaic, roofs, solar cadaster

Objectives:

the objectives of this action are: - to help citizens to get information on the solar potential of the roof of their own houses - to evaluate different PV technologies and their suitability for installation in different locations and conditions - to disseminate knowledge regarding the solar energy exploitability

Activities:

The Solar Cadaster is the result of a joint project between the city of Bressanone and the Institute for renewable energy of Eurac - Bolzano. The city of Bressanone provided the baseline cartographic data of the city while Eurac provided the scientific and technical knowledge to simulate and validate the estimation of solar irradiation on the roofs of the buildings. The database has been published through a webGIS-portal freely accessible by all the citizens of the city.

Results:

Photovoltaic technology can help to reduce CO2 emissions associated with electricity production from fossil fuels. The production of electricity can be decentralized reducing also the energy losses due to its distribution on the network. The action can also contribute to reach the energy-self-reliance target of the Municipality. Citizens can, finally, play and familiarize with this innovative concept of energy production, verifing directly which is the potential of their own roof. SMEs, like installers of PV panels, can provide better offers to their customers according to the effective potential of their roofs. From 2007 to 2010 Bressanone installed 155 new Photovoltaic plants equivalent to a total installed capacity of 2.675.772 kW and a production of 1.462.400 kWh in 4 years.

II Assessment criteria

Mitigation effects: Very high

Photovoltaic technology will help to reduce CO2 emissions associated with electricity production from fossil fuels.

Impacts on adaptation: Neutral

No impacts on adaptation can be identified.

Impacts on environment:


- Landscape: Negative
- Alpine ecosystems / biodiversity: Neutral
- Water / soil / air: Positive
- "Other": None

The integration of PV panels on the roofs is still critical from the point of view of the landscape. No impacts on biodiversity or water can be identified. A positive impact on soil preservation is identified on the use of roofs to install the PV panels instead of the occupation of agricultural land.

Impacts on society:


- Social justice: Positive
- Regional / cultural identity: Positive
- "Other": None

Both social justice and regional/cultural identity can be positively impacted. On the one hand because the local production of energy can contribute to be autonomous from external sources of fossil fuel located in complex and critical areas of the world. On the other hand the target of energy self reliance can positivly affect the cultural identity of the citizens that actively manage their own energy plant.

Impacts on economy:


- Employment / job creation: Positive
- Added value / income: Positive
- Know how / competitiveness: Positive
- "Other": None

Positive effects are identified in job creation because the Solar Cadaster can promote the sector of installation of PV panels. The added value to a house that produces energy by itself is high. The market of PV panels installation requires an improvement in the knowledge in this sector.

Public relations impact and awareness-raising: High

The Municipality directly promoted the action. The cadaster has been published via a web-portal and is freely accessible via internet.

Transferability: Very high

The action is easly transferable. The data required for the eleboration of the solar potential are cheap if compared to the total revenue produced by a solar cadaster in the different involved sectors.

Cross sectoral and integrative approach: High

The action can contribute to reach the energy-self-reliance target of the Municipality.

Good governance: High

The Solar Cadaster is the result of a joint project between the city of Bressanone and the Institute for Renewable Energy of Eurac - Bolzano. The Autonomous Province of Bolzano provided a LiDAR database to the Municipality of Bolzano. This database let to obtain a very high detailed 3D model of the houses' roofs.
