BESOS: Building Energy decision Support systems for Smart cities
The strategic goal of BESOS is to enhance existing neighbourhoods with decision support system to provide coordinated management of public infrastructures in Smart Cities, and at the same time provide citizens with information to promote sustainability and energy efficiency.
About the Project
The smart city era is significantly going to impact existing energy related behaviours as well as relevant business transactions. The fine-grained visibility of the energy signatures – i.e. load and production curves - of prosuming devices and systems in a smart grid, can be coupled with near real-time analytics and control which will enhance decision support processes taken. By being able to access a wide range of previously isolated information, doing real-time analytics, taking decisions and enforcing those decisions into the infrastructure, a better managed system will emerge. Taking into consideration that this is a highly heterogeneous ecosystem, significant challenges lie ahead.
Future smart cities rely upon their neighbourhoods to be monitored and managed efficiently. However the various neighbourhoods might significantly differ from each other and follow their own goals. The infrastructure on the districts is expected to be highly heterogeneous - e.g. with public lighting system, urban heating system, public buildings, electric vehicles, micro-generation, residential prosumers, etc. Addressing also the business perspective of smart cities, public services cannot be assessed exclusively against economic Performance Indicators (KPI) and therefore social impact and non-monetary benefits must always be considered; while citizens need to better understand the cost of energy and services in order to trigger modifications on their behaviour leading to energy savings.
In such a mixed, dynamic, non-standardized and highly complex framework, current business and management applications have a very hard way to dynamically discover, integrate, and interact with the already existing EMSs in a smart city. Vice versa, the device world has very little chance of fostering intra-/inter- collaboration capabilities and take advantage of the opportunity to offer their functionality in tight interaction with others. As such, the move towards an information driven network rather than a communication one is needed. Hence, in the context of a smart city, the proposed BESOS framework is abstracting from the actual underlying hardware and communication-driven interaction and focuses on the information available towards the establishment of a data and services driven operational framework.
Figure 1. BESOS platform high level architecture
Figure 1 depicts a high level view on the BESOS expected contribution to support main actors in a smart city in establishing an easier and more open collaborative service schema. Different EMSs within a smart city are able to share data and services through a new Open Trustworthy Energy Service Platform (OTESP). Stakeholders as ESCOS, public authorities, Distribution and Transmission System Operators (DSOs and TSOs), and domestic users, are able to access and interface the existing infrastructure in smart cities, not only to analyse in real-time the data from such systems but also to implement common strategies enforcing energy efficiency. A key feature of the OTESP is the adoption of secure and reliable protocols – both for communication and data management - to ensure the trustworthiness of the approach and the correct treatment of private information. Moreover, the data modelling in the project consider the openness of the information whilst ensuring the security of the approach.
Hence, the Open Trustworthy Energy Service Platform act as gateway to the different stakeholders at the demand and supply side on a smart city, who already count with their own Energy Management Systems for local decisions and energy management. Typically these stakeholders operate distributed renewable sources – such as wind mills and PhotoVoltaic (PV) parks-, public lighting systems, run facility management on buildings, heating management, electric vehicle management etc. On the application side, public authorities – i.e. municipalities -and facility owners are the main user groups targeted by BESOS. They are provided with a Business Balanced Score Card (BBSC) to audit SLA established with the ESCOs and Facility Managers (FM) against a number of KPI, both considering economic and social impact. At the other side of the contract, Energy Service Companies and Facility Managers form the second main target group. They make use of the same tool –BBSC- to analyse new business models and the commissioning and maintenance activities against a number of KPI, and also provided with a DSS Cockpit to Monitor and Control (M&C) information from the infrastructure and establish coordinated energy efficiency strategies.
As an additional benefit the deployment of an open infrastructure for data and service management, we open new opportunities to mobile application developers willing to increase energy efficiency awareness among citizens. As a proof of concept, we implement and test an interface to inform citizens and try to modify behaviours by means of challenges – in this way the users not only participate as observing subjects but also are invited to affect the energy efficiency of a smart city.
Pilot Site Demonstration
All BESOS applications are tested in two European metropolis: Lisbon and Barcelona. The two pilot cities are leading cities on the energy efficiency arena for Smart Cities setting the optimal testbed for the evaluation of BESOS platform. The main goal during the demonstration phase is to involve as many different energy management systems in a city as possible, focusing on the diversity of assets that consist of a concrete pilot site.
Lisbon is the capital city and largest city of Portugal with an active commitment towards becoming a smarter city as an answer to the biggest challenges faced by the city today. In the context of the project we are examining the integration of multiple types of assets and infrastructure in order to evaluate the different views of BESOS framework. More specifically:
- Energy management in residential buildings where the main objective is to trigger citizens to energy efficient behaviours through real time information about energy consumption and the establishment of a gamification framework.
- Energy management in service buildings where smart metering systems provide real time data towards the implementation of different control strategies and evaluation of alternative tariff polices.
- Energy management in Public Lighting and Traffic Lights as a high consuming asset on large cities. The goal is to demonstrate and evaluate different control strategies taking into account context- environmental & mobility patterns-conditions.
- Electricity production (micro-generation) and renewables and Integration of RES in smart city management framework.
- Electric mobility addressing the mass penetration of Electric Vehicles in the near future. The goal is to incorporate mobility patterns with energy management systems towards the optimal management of EV fleets.
Barcelona is the capital of Catalonia, the second largest city in Spain and a major cultural and economic centre in south-western Europe. Barcelona is a leading city and has extensively support the development of urban-labs involving citizens in the definition of the smart city concepts. Actually, the city plays a leading role at several international initiatives proposing ‘new open, global, and progressive working framework for cities worldwide to assess and improve performance in environmental sustainability, economic competitiveness, quality of life, and city services, by innovating and demonstrating new leadership models, new ways of engaging society, and by leveraging new information and communication technologies (ICT)’.
Barcelona is working towards a more sustainable city through an energy model, which allows more efficient management of resources and greater savings. It is applied in the field of ICT (Information and Communication) with the objective of providing the city with infrastructures that ensure sustainable development and a higher increase in the quality of life of citizens. Within BESOS project, the integration of different types of assets is considered:
- Energy management in service buildings through the integration of heterogeneous solutions from different vendors in order to evaluate the smart city concept in practice.
- Energy management in Public Lighting and Traffic Lights by integrating assets from different parts of the city and further implementing context based control strategies.
- Combination of Electric Vehicles and local RES generation towards the implementation of multi objective control strategies that enable the maximum RES exploitation and optimal charging of electric vehicles.
- Along with the exploitation of local RES, the integration of large scale wind parks is examined in order to examine the mass penetration of large RES and further exploitation in smart city concept.
The adaptation of heterogeneous types of devices is a huge task but also a main goal of BESOS project towards the establishment of a sustainable and energy efficient environment in large scale demonstration sites.
Since BESOS is a demonstration project oriented, the rigorous measurement and evaluation of the energy and emissions savings achieved by the technologies integrated in BESOS will maximize the impact and wide scale market adoption. Towards this direction, the main objective of BESOS project is to collect the experiences and lessons learnt with the adaptation/integration of legacy EMS to the new envisioned Smart city approach and further enable the transferability of BESOS solution to other E.U. Cities. Lessons learnt from the efforts in integrating the existing EMS are depicted and provided as a set of guidelines or best practices. Therefore, the implementation of standardized and interoperable solutions is one of the main outcomes of the proposed framework, enforcing in that way the easy adaptation of 3rd party applications and energy management solutions to the BESOS platform.
