ELLIOT project - basic facts

ELLIOT: Experiential Living Lab for the Internet Of ThingsFramework Programme 7, ICT Call 5 : FP7-ICT-2009-5Objective ICT-2009.1.3: Internet of Things and Enterprise environmentsProject type: STREP / Collaborative research, Project No: 287560Duration: 30 months (September 2010 - February 2013)Web: www.elliot-project.euCoordinator: TXT Polymedia S.p.A., ItalyPartners: 9 + 3 (Italy, Germany, France, UK, Bulgaria, Hungary, Slovakia)

Aims of the project:• the development of an Internet of Things experimental platform,• to directly involve users (customers, citizens) in co-creating, exploring and

experimenting new ideas, concepts and technological artefacts,• to study a potential impact of IoT and the Future Internet in the context of the

Open User-Centred Innovation paradigm and of the Living Lab approach.



5

Living Lab approach to IoT

Objectives, principles of the approach in ELLIOT:• Explore the potential of user co-creation techniques and tools, such as serious gaming,

participative requirements engineering and verification/validation, in the context of IOT.• Study and develop a set of KSB (Knowledge-Social-Business) Experience Models

integrating social, intellectual-cognitive, economical, legal and ethical aspects related to the use of IoT technologies and services into a single, “holistic”, meta model.

ELLIOT Living Lab in Slovakia

Pilot name: ECOffices - Ambient Intelligence in energy saving

• The Smart Office use case:• Integrates AmI-IoT & semantic technologies, with respect to the KSB

(knowledge-social-business) aspects of user interactions• Targets the optimization of energy consumption in offices

• Focus, goals:• experiment the ELLIOT outcomes and the new semantically enhanced AmI

technology in the Energy test case in Slovakia• demonstrate the platform capabilities towards a positive impact on

environment (energy consumption, CO2 footprint)

• Technology:• AmI-IoT: based on LinkSmart middleware, using outcomes of the FP7

project ebbits.• Semantics: device ontology, fusion of generated events, business rules• Devices: energy consumption, environment conditions, and occupancy

sensors - Plugwise, Arduino, …

The Smart Office concept

From “Smart Houses” to “Smart Offices”Smart House:

• a house that has advanced automatic systems for lighting, heating, air-conditioning, window and door operations, security etc.

• many solutions, both commercial and research

Smart Office:• to employ the paradigm of the smart house in a business environment,• inclusion of / integration with business processes,• optimization of existing processes in an organization (or office),• ability to implement new and more efficient business processes,• expected benefits on the user level regarding to more organized and coordinated

social interactions.

Challenges:• correspondence of AmI-IoT with business processes,• acceptance and support from the side of employees (and management),• possible solution: AmI-enhanced services and processes should follow the

recommendations of IT Infrastructure Library (ITIL, http://www.itil-officialsite.com) and the related standard ISO/IEC 20000:1-5.

Application partner : RWE IT

RWE IT Slovakia, http://www.rweit-slovakia.com

• belongs to RWE group, leading energy (gas, electricity) distributor in Eastern Slovakia

• daughter company of RWE IT GmbH, IT services provider for RWE

ECOffices pilot is implemented in the premises of RWE IT:

• office type: open space room

• 8 employees in the office (administration department)

• central heating, air conditioning individually controlled within the office

• equipment: computers, monitors, phones, 2 x printers, 1 x scanner / copier



10

ECOffices : the Living Lab concept

General Goal: a systematic and iterative user co-creation approach integrating research and innovation processes towards the energy efficiency in business environment, using AmI-IoT technologies (enabled by the LinkSmart system).

Living Lab scenarios

Scenario #1: Exploration of a suitable occupancy sensing device• 4 different types of occupancy sensors identified by IoT experts• Goal: Users exploring, experiments and evaluation - to find a balance between:

• Comfortable environment• Amount of saved energy / CO2 emissions• Privacy loss

Scenario #2: Process-based adaptation of the working environment• Uses occupancy sensor as an output of scenario #1.• Template process model given, e.g. predefined work hours, seasonal settings of

environment• Adaptation of working environment according to user preferences• Goal: Adapted process model as an explicit representation of the working environment

settings in a given time scale

Scenario #3: Competition on energy savings in the office• Users playing a “game” saving real energy• A visualization showing actual consumption and CO2 footprint data, overall ranking, etc.• Ranking provided to decision makers -> e.g. awarding of winners, motivating others, ...



13

Indicators for KSB analysis

• Knowledge:– Sensing affordances KPI: Frequency of "Power consumption overview" portal

page views during a specified period– Conation (Desire) KPI: Number of positive reactions to switch off air conditioning

and opening a window

• Social:– Mutual goodwill KPI: Number of user profiles with similar settings on temperature

and lighting– Community behavior KPI: Number of profiles having the proportion of light /

temperature profile settings of particular user to whole group average above a threshold value

• Business:– Performance level KPI: Overall amount of saved energy (in a specified period,

comparing to an average of consumed energy)– Reliability KPI: Number of errors / exceptions in the log during specified period

Schedule of the pilot:• 1st round: May-June 2012 (completed)• 2nd round: end of August• evaluation: end of 2012

Technology:• Devices installed (see figure)• Data monitored and collected from the 1st

round, evaluation is ongoing, use of the data in occupancy sensing

• Interface to ECOffices system is a web portal• Arduino-based prototypes (see next slide)

Involvement of users:• Initial user requirements and information about

user habits collected by a questionnaire• Smart Office Portal - Web application for

gathering user experiences was developed• Success factors and KPIs (focused on KSB

aspects) were specified and provided for analysis into ELLIOT platform

Log format: [Immediate power consumption in watts] [ID: MAC address of sensor] [timestamp]

Monitoring and data collection

Data sources:• sensors: power consumption on plugs, outdoor / indoor temperature, light intensity, motion sensors

• devices: RFID cards for occupancy sensing, air conditioning control unit, LinkSmart middleware system (provides system logs)

• user interface: web based Smart Office portal (user interactions, profiles & preferences, system logs)

Means of collecting the data:• direct measuring - outdoor / indoor temperature, power consumed on a single plug, light

intensity on a single place, etc.• a value fetched in a single shot from a sensor, e.g. Immediate power consumption in watts,

temperature value in °C, etc.

• simple calculation - i.e., CO2 footprint (CO2 emission factor for electricity = 0.527 kg / kWh,

http://www.carbonindependent.org), light intensity in whole room, etc.• value calculated by a simple algebraic statement from one or several directly measured values• data series of two dimensions (e.g. indoor temperature for given time period)

• data merging - i.e., occupancy sensing (calculated by merging Power consumption data analysis,

PIR motion sensors, and RFID cards), average energy consumption of a working team for a given time period, etc.

• multi-dimensional data structures, calculated by algebraic statements and rules



17

Summary, future steps

Work done so far:• LinkSmart middleware adapted for the ECOffices Living Lab• pilot prototype implemented• 1st round of experiments on Scenario #1 accomplished

• Occupancy sensing: simple motion sensor - precision 45-50%,combination of motion sensors, RFIDcards, and energy consumption monitoring - precision 94%

• data from sensors collected and provided to the ELLIOT platform for KSB analysis

Next steps:• new types of devices - actuators: air conditioning control, heating control, light switches

• business rule / process engine, based on Drools framework, www.drools.org• a generic process model for Scenario #2 will be developed• Scenario #2 experiments, evaluation

• the Smart Office portal will be enhanced to enable the “game” on energy savings• Scenario #3 experiments, evaluation

• ECOffices Living Lab has an ambition to join the European Network of Living Labs (ENoLL, www.openlivinglabs.eu) in its next wave.
