Promoting district-level energy saving and optimization through ICT. For this reason, DIMMER has developed an open web platform with real-time data processing at the urban district level, intended as a set of buildings and technology networks that interact with each other.
Three types of users involved: public administrators and planners, building managers and owners, energy professionals. Two test sites: Turin and Manchester. These are two non-homogeneous urban districts, one to the north and the other to the south of Europe, for which both public buildings such as university campuses or schools and private tele-heated buildings such as the area of the district of Centro-Crocetta di Torino have been taken into consideration.
In particular, the research focused on: interoperability aspects between ICT systems, extension of BIM (Building Information Model) modeling from the single building to the district, integrating GIS (Geographic Information System) and SIM (System Information Model) data. All developments were carried out using open source software and libraries.
There is also a great commitment to involve and co-create the DIMMER solution in cooperation with end users, such as public administrators and energy managers, building managers and owners, school executives and energy professionals, involved from the early stages of analysis up to testing and final evaluation of the DIMMER prototype.
Thanks to the project and collaboration with Politecnico di Torino and Iren, CSI Piemonte has developed new skills on energy and sustainability, particularly useful for the creation of energy indicators in the DIMMER Web GIS Dashboard.
The contact with the DISEG department turned out to be very interesting, which gave the opportunity to acquire more skills on BIM modelling, particularly useful in the context of the new Italian Procurement Law.
Active collaboration with the Polytechnic of Turin and the Siebel Institute to prepare projects for other Horizon 2020 Programme Calls.
The DIMMER project has achieved many results:
- CSI-Piemonte has created the DIMMER Web GIS Dashboard used by both cities under study, Turin and Manchester. A Decision Support System tool for public administrations, energy utilities and trade associations that provides monitoring and management of information from the district's energy network.
- Created the "Cost Benefit Analysis Tool", a web application hosted as a plug-in within the Web GIS Dashboard, which allows to simulate redevelopment scenarios for groups of buildings, districts and even on the scale of an entire city. In addition to the economic evaluation of the intervention and the installation cost, the simulation proposes MWh, tonnes of Co2, the possible savings and the years needed to cover the investment.
- Geo services GeoJson: construction and maintenance of web-based network data display services: district heating in Turin and electricity grid in Manchester.
- Mash up: the buildings databases and technical paper available to the City of Turin have been harmonized with the data coming from utility companies, in order to visualize the real time energy measurements and the calculated indices on the buildings of both pilots.
- 3D visualization: creation of 3D visualization applied to buildings and network devices. Using the open source globe CesiumJs for 3D visualisation (link to http://cesiumjs.org/).
- For all the buildings for which the project produced the BIM models, the visualization was carried out at higher levels of detail:
- LOD2: characteristics of exterior walls and roofs
- LOD3 addition of openings
- LOD4 addition of the position of the sensors inside the rooms.
