The “smart cities” approach can help to improve the citizens’ quality of life in
accordance with the objectives set by sustainable energy policies of the European
Union with the target of reducing by 20% the CO2 emissions by 2020
Smart cities rely on the availability of data
although there are more and more energy and other related data sets available, it
is necessary to integrate them in order to provide the various key actors
the information they need to make well-informed decisions
it is not enough to have access to the data
it is necessary to integrate data from different domains in order to
understand the interrelationships between the various areas –energy,
economics, social– that are involved in the reduction of carbon emissions in cities

these technologies can be applied, mainly, to support data integration
processes and to overcome the interoperability barriers between the
data generated by the different users and by the applications
There are well-known issues:
• Type of accessing
• Syntax of the content
• Data format
application of Semantic Web technologies can help to overcome some
of the difficulties which are intrinsic to the development of decision
support systems which rely on distributed and heterogeneous data

…data interoperability is not only a technological challenge.
the technological solutions need to be embedded in scenarios which encompass
strategic goals, users and systems, along with the tools to analyse the data
It also involves devising and applying procedures to avoid doing

3. The development of the OPTIMUS DSS
The goal of the OPTIMUS project is to help local authorities to
optimise the energy performance of public buildings by applying
the short-term actions suggested by a Decision Support System (DSS) which handles data obtained in a diversity of sources and domains:
- Weather conditions
- Social behaviour
- Building energy performance
- Energy prices
- Renewable energy production
Álvaro Sicilia – ARC, La Salle
3. The development of the OPTIMUS DSS
The OPTIMUS DSS optimizes:
• boost time of the heating/cooling system taking into account the
forecasting of the outdoor/indoor air temperature and the occupancy
of the building.
• selling/self-consuming of electricity produced by a PV system
considering different scenarios of energy market and strategies (green,
finance, peak).
• adjustment of the temperature set-point, taking into consideration
thermal comfort parameters (e.g., Predicted Mean Vote index) using
occupants’ inputs gathered with a mobile app.
Álvaro Sicilia – ARC, La Salle
3. The development of the OPTIMUS DSS
The innovative approach of the OPTIMUS DSS is based on:
• The use of multidisciplinary data sources
• The semantic modelling of data using Semantic Web technologies
• The integration of data for energy optimization

results obtained in the SEMANCO project:

To highlight the strengths, the vulnerabilities and the
opportunities of the city in which the DSS is going to be
used.
A Smart City Energy Assessment Framework
(SCEAF) has been developed to estimate the energy
efficient measures based on the suggestions of a
decision support system or of an energy management
strategy.
A list of KPIs has been created to evaluate the DSS.

4. Defining the
application scenarios
A scenario describes the components that the DSS needs to suggest the end-user a short-
term action: input data, prediction models, intelligent rules, action plans and KPIs.
For example, a scenario would be: “To optimize the boost time of the heating/cooling
system taking into account the forecasting of the outdoor/indoor air temperature and the
occupancy of the building”

At the core of the DSS engine lie the intelligent rules, a set of procedures
to check if the input data match certain patterns to derive an action plan.
The intelligent rules are fed with predicted, real-time, and static data.
Prediction models to forecast:
- energy consumption of a building
- indoor air temperature
- energy prices
- energy production of photovoltaics panels

Álvaro Sicilia – ARC, La Salle
4. Conclusions / Collaboration
A first prototype of the DSS has been created based on the findings of a requirements
analysis conducted in three pilot cities
The OPTIMUS DSS represents an innovation with respect to the existing systems in so
far it is able to interlink five types of heterogeneous and dynamic data sources in order
to suggest short-term actions plans that enable public authorities to reduce energy
consumption in public buildings
A first prototype of the DSS has been developed including three action plans, four
prediction models, and data integrated from five sources. It will be applied in the three
pilot cities, operating under real working conditions
Requirements capturing is not a one-time process. It needs to be continuously validated
with end-users and domain experts
Álvaro Sicilia – ARC, La Salle
4. Conclusions / Collaboration
We (consortium) are discussing how to publish the main assets
of the project in order to be reused/extended by third-parties:
- OPTIMUS ontology
- Semantic Framework (based on Ztreamy system)
- DSS engine (Intelligent rules, prediction models…)
- Data collected (RDF)
- Mobile App
