Lule Living Lab PilotA warm welcome to the Kulturens Hus (House of culture) in Lule,the northern metropolis of Sweden and cultural town district of 2007.In the spring of 2005 the rst sod was cut and in January 2007 theopening took place. House of culture is Lules new meeting place,completing the image of Lule as a town where cultural expressionsgather under the same roof, cross-fertilize each other and give thevisitors experiences above what was earlier possible. With 13.900square meters of public area and 6.000 square meters of garagearea, in 2008 the building with 80 persons in its staff has received564.231 visitors.

The building a a Library, Concert Hall, Restaurant, Caf, Art Gallery,Tourist Agency, Conference and Ofce areas. The selected roomsfor the SAVE ENERGY pilot are the restaurant, ofces and entrancedoors. The building is equipped with a completely new state-of-the-art energy management systems controlling the environment forevery room of the building.

The house of culture is connected to the district heating systemand district cooling system which works with the nature, using coldwater from the river. The heat dump is located in the town bay.The build has a high level energy management system but aimsto achieve more energy savings involving and promoting usersawareness. The Lule pilot team divided the building into differentimprovement areas that were equipped with the necessary SmartMetering equipment.

The total energy consumption is measured for the whole house.There are four areas selected for testing. These are the restaurant,two separate sections of ofce rooms and the main entrance doors.For the restaurant, electricity, temperature, hot and cold waterconsumption (energy) is measured. For the ofces electricity ismeasured. For the entrance doors the user behaviour is measureddirectly by counting the number of persons using the open doorbutton or not.

For the entrance doors the measurement of user behaviour changesis achieved in three steps. Step one was measuring the old wayof using the entrance doors. In step two a text saying please helpus save energy is introduced. In step three ICT technologies areintroduced to support the user taking the right decision.

The creation of awareness and change of behaviour by the usersof the Lule pilot is also driven from the Serious Game and theestablishment of the Living Lab methodology. A Living Lab wascreated at the pilot premises and thus being an active environment,where the users of the pilot contribute to the co-creation ofinnovative solutions and motivate themselves to change their energyconsumption behaviours.

Lule Technical SolutionEnergy consumption measurements at KulturensHus are being collected using a Saber basedsolution system and an MbusMaster system,both developed by KYAB Lule AB. The differentmetering devices were interfaced with MBus, usingan MBusMaster acting as a hub. The MbusMasterinterfaces several metering devices, connectingthem to the Saber system via RS485 interfaces,i.e. ModBus/MBus.

The data collected by the Saber system is stored inits local database and forwarded every minute (orwhenever there is internet connection available)to the Saber Web Portal. At the Saber Web Portal,the data is stored into a secured database. Theweb portal provides a user friendly interface forremotely viewing and understanding the data asstatistics, graphs and comparison trends.

The data is also feed back to Kulturens Hus intocomputer integrated 15 and 42 LCD displayswhich show a simple to understand, user friendly

and graphical representation of the pilotsprogress in lowering energy consumption at thebuilding. The presentation is not only viewed byon site building staff, but also by the visitors andcustomers of Kulturens Hus, who have access toit. Furthermore, the data collected at the buildingis also forwarded to the ISA central platformservice to be used by end-user services, namelySerious Games.

The metering devices installed at KulturensHus allow the collection of data on electricityconsumption at the restaurant and the two ofcespaces, air temperature and hot and cold waterconsumption at the restaurant areas. Additionallythe use of the buildings main entrance doors ismonitored, which has great impact in maintainingthe buildings internal temperature, especiallyconsidering the northern Swedens cold weather.

Leiden Living Lab PilotThe key objective of the Leiden Pilot is to improve the energyefciency at a public house hosting a variety of public services for thelocal communities. The Leiden City Hall building is owned by the cityof Leiden. The pilot provides information on energy use in a limitednumber of ofces in the building during a period of about a year whileproviding feedback to the participating employees. An indication isobtained about the cost effectiveness of the method and the energysavings that can be obtained, aiming at demonstrating the use ofICT for energy savings in public buildings and spaces through userbehavioural changes.

Savings can be attained on the use of electricity (lighting, computers,and appliances), heating and cooling. During the experiment a test isconducted for the hypothesis that energy consumption behaviours ofemployees can be changed by providing them with current informationabout the energy used at their desk and in their room. Indications arealso obtained about the amount of energy that can be saved usingthis approach.

The Leiden pilot is carried out in ve ofce rooms of the Leiden CityHall building. These rooms vary in size, location, equipment, numberof desks, persons and the type of activity. For every pilot room there isone reference room that is very similar. Employees participating in theve pilot rooms get real time information about their energy usage.The reference rooms are used to provide comparative reference dataand its employees do not get any information about their energyusage. This allows testing the hypothesis that providing informationcan change personal energy consumption behaviours.

The light in the rooms can be controlled by two or four switches bothfor two sets of uorescent tubes at the same time. Rooms havevenetian blinds that can be opened and closed manually. The roomshave two windows that can be opened or closed by the employeesand two hot water radiators adjustable by them, one radiator has athermostatic control valve, and the other has a manual valve.

Both electricity usage and heating required for each room aremeasured; personal electricity usage per desk, e.g. by computers,screens and desk lamps, electricity usage per appliance in a room,e.g. by lighting and other room-specic devices like coffee machinesand printers, heating energy supplied to the room by each hot waterradiator is estimated from the radiator surface temperature and roomtemperature.

Employees can inuence the energy consumption by; switching lightsor equipment on/off, opening or closing the manual radiator controlvalve, changing the set point of the thermostatic valve, opening orclosing windows, opening or closing doors, and by adjusting thevenetian blinds. During the experiment and in consultation with theemployees decisions are made to place extra sensors to evaluate ifextra information might help the user to save more energy.

Leiden Technical SolutionSensors were installed for the desks (computer screen,computer and other electric equipment), lighting(separate for each appliance) and temperature (eachradiator and air outlet). Rooms with special equipmentlike a private coffee machine, then an extra sensorhas been added for this appliance. Plugwise sensorswere user for electricity measurements and Sensitesensors for temperature measurements (LogiSphereBN215 for room temperature and ST208 for radiator

surface temperature). The measurement data fromthe sensors is collected by the Plugwise concentratorsand Sensite HBL100 Wireless Network Controllerswhich communicates with an AnyWi router using anopen XML-based protocol.

The AnyWi router connects via Internet to theSAVE ENERGY technical infrastructure. The primarycomponent of this infrastructure is the ISA centralserver (iCenter), where complex data aggregationtakes place and data is made available to end-userservices, namely Serious Games. The collected datais also processed and presented in real time to the

users through the web portal and in addition a directsimple feedback to the users is provided on their PC.

Data on current energy use is available locally toparticipating employees at 5 minutes intervals. Thedata stored in the local repository can be used forstatistical analysis of trends and effects.

Energy use not only depends on the behaviourof users but varies strongly with e.g. outsidetemperature and time of year (daylight and sun

shine), work pattern (meetings, coffee breaks, etc.)and personal behaviour (type of work). Thereforethere is intrinsic noise in these measurements.To be able to interpret the results and draw moreaccurate conclusions, the overall process started bymeasuring the base-line use of all the rooms involved,subsequently measuring the energy consumption atthe pilot rooms and the reference rooms. During theexperiment phase of the project the data is analysedin order to determine how long the pilot should runand whether adjustments are required.

Lisbon Living Lab PilotThe Lisbon pilot takes place at the Lisbon Municipality main ofcesbuilding, a building with 1.800 employees which started operating in 1998,and serving both as administrative ofces and public attending services.Urban planning and urban management, the denition of a strategyand the mainstreaming of good environmental practices for the city ofLisbon are an important part of the Lisbon Municipality responsibilities.Being Lisbon Portugals capital and its political, economic and culturalcentre, is compelled to lead by example with good practices in urbanplanning, construction, urban management and mobility, respecting thevalues of sustainable development, aiming to promote a higher qualityof life for its citizens, today and tomorrow. The Lisbon Municipalityhas a strategic partnership with Lisboa E-Nova agency, which holds anactive and essential role in all Intervention Projects.

The objectives of the Lisbon pilot are to improve the energyenvironmental performance of ofce buildings in Lisbon, with all directand indirect benets, including the reduction of energy consumption(through energy efciency), the increase of indoor air quality, thermaland visual comfort conditions and the promotion of connectivity amongbuilding users and with the city at large. One of the results should be asignicant reduction of CO2 emissions. The building was built with littleor no consideration for the energy environmental dimension, very much

like most ofce buildings in Lisbon, therefore this pilot will becomea very replicable case study, and a core reference with guidelines toimprove the energy efciency and environmental performance of ofcebuildings.

The pilot project started at grass roots level, by identifying the measuresthat needed to improve the building physics; bringing up to date thebuilding envelope and infrastructure, decentralizing energy productionrelying on renewable energy sources, modernizing building managementsystems, including increasing intelligence in the interaction with theenergy grid, greening information and communication technology tomaximize connectivity between users.

There are expected impacts in Public Administration awareness ofEnergy Efciency through the dynamic, real time information displayingand the publication of terms of reference for tender specications, madeavailable to the buildings users and to other services and institutions.

It is also expected stronger commitment to Energy Efciency Policiesin line with the recently approved Portuguese National Action Plan forEnergy Efciency, the Municipality will further explore interventionopportunities and enhance the city overall energy performance, settingclear energy performance targets for 2013.

Citizens awareness and empowerment towards Energy Efciencyoriginated from the communication with the public will not only lead tomeet the project objectives and results but will actively intervene withthe public and empower their actions by disseminating best practiceson how individual acts can have an important impact in the globalenvironment.

Lisbon Technical SolutionThe Lisbon Pilot was designed to use a complete ISASmart Metering system, being all the equipmentsbased on ISAs integrated solution for building energymonitoring. The range of the system goes fromsensing, data communications, to user interfaces ofinformation displays with local and remote real timedisplay capabilities.

The pilot monitoring relies on several parametermeasurements, requiring different equipment

and technical solutions. For the Lisbon pilot, twoblocks of the Lisbon Municipality building are beingmonitored, with the ISAs iMeterRail smart metersdeployed in these two blocks, allowing the totalelectricity consumption to be measured. It is alsoused to measure different types of electrical circuits,thus creating a segmentation on the electricityconsumption, such as air-conditioning, lighting andelectric plugs.

The iMeterRail devices are connected throughRS485 bus lines to a TCP/IP conversion bridge. The

signals are collected and sent to the network routerand nally stored in the local server.

In order to be able to perform sub-metering, severalplug meters were deployed and each applianceselectricity consumption data is collected usingiPlugMeter sensors. This data is then transmittedto the system using one of the wireless protocolsavailable (Bluetooth, Z-Wave or ZigBee).

The local server is based on a RcWare system thatperforms two distinct tasks: sending data to theISA iCenter central server through the internet and

displaying the real time information on the local LCDdisplay which allows the users to have a continuousoverview of its energy efciency performance.

Additionally, users have access to the ISA web portalwhere they can access more detailed informationand one simple applet software that is installed ateach users PC displaying periodic advice messagesinviting them to have energy efcient behaviours,like turning off their monitor when they leave orunplugging phone chargers if they are not beingused.

Manchester Living Lab PilotThe pilot is located within Manchester Town Hall, which can be foundat the centre of the historic city of Manchester. The building covers40.000 m2 and sits on an unusually shaped triangular site. The TownHall was one of the most technically advanced large buildings of itsdays, built at a time when Manchester led the world in engineering. Itis now regarded as one of the UKs nest examples of gothic-revivalarchitecture and has been listed as an historic monument with the UKshighest grade of national protection (Grade I). Originally constructedto be lit by gas, all electrical installations are post construction.Development of the electrical infrastructure has been piecemeal andwhilst meeting current safety standards, much of it is now dated. Thebuildings complexity and issues of adaptation within strict conservationregulations, presented real challenges in pilot development.

The Town Halls design and heritage also presents particular challengesin terms of energy efciency and carbon emissions. Under the EU EnergyPerformance of Buildings Directive, large buildings that are occupiedfor either public authorities or institutions providing public servicesare required to publicly display energy performance certicates. Onthe scale of A (best) to G (worst) the Town Hall is rated as E.

The aims of the Manchester pilot are to demonstrate that is possible todeliver energy improvements to the most challenging buildings in aneconomically viable way, provide a blueprint for similar improvementsin many of the other 300 Council buildings across Manchester, andlook at how carbon reductions can be achieved through an increasedunderstanding of energy use and associated behaviour change.

The pilot accommodation is on Level 7 of the building (roof level).These rooms are split between two sides of the building on a mezzanineoor. Due to the age of the electrical infrastructure identifying whichdistribution boards provide services to which rooms was a real challenge.Therefore the rst phase consisted on an investigation by the installerto isolate the feeds to different areas following which the actual pilotrooms were selected.

The energy monitoring of the pilot rooms include appliances; theofces use standard ofce equipment PCs, photocopiers, desk lamps,printers, shredders, phone chargers, kettles (there is no dedicatedkitchen area). A full audit of all equipment was carried out. Specialfocus was also given to lighting; the rooms are illuminated by centrallights. On one side these are controlled by motion sensors and on theother they can be manually switched on and off.

In each pilot room measurements take place for lighting and appliances,being the general areas the ambient lighting and air temperature.Internal ambient light and temperature data is recorded to take part inthe user experience at their working environment. Weather data forthe period is obtained via web sources and used for data analysis.

The selected technical solution was based on theequipment supplied by Schneider Metering inconjunction with their approved installer, SamelcoAutomation Systems Ltd. The system collects datafrom the distribution boards using CT strips (CurrentTransformers) and is transmitted to a Branch PowerMeter (BPM). The Branch Power Meter has thefacility to monitor up to 24 individual single phasecircuits. A Belden 9841 twisted pair connects the

BPM to an Ethernet Gateway (EGX100). Using CAT 5cable, data is transmitted from the EGX100 to a miniserver PC which gathers the data and stores it in aSQL database. The system front-end is web basedand provides access to the system functionalities.

As standard the Schneider equipment samples at5 minute intervals with smaller sampling periodspossible, increasing the magnitude and accuracy ofthe data recorded. Measurement data is recordedin kWh. The data on energy use is visualized bythe users in real time throughout the working day

showing the total amount of energy consumption.This is displayed continuously, showing immediateimpact changes as well as the average energyconsumption (kWh) through local LCD displays.

The University of Salford (USAL) is responsible forthe development of methodologies and analysis ofthe collected data. The tasks include questionnaireand survey design, developing statistical models,analysis and interpretation of the data.

In terms of setting up the experiment and creating aset of reference data, and because the rooms at theManchester pilot are not identical (no rooms in thebuilding are), the option was to generate a controlperiod where the rooms act as their own reference,using a system of comparable months. Whilst scalmetering covers the whole of the Town Hall complex,there is no ability to determine usage by space hencethere is no baseline data available for electricityusage in the pilot rooms. The Control Period is thenused to efciently generate baseline data.

Helsinki Living Lab PilotThe city of Helsinki owns about 1.200 public buildings including200 schools, 350 kindergartens, 7 hospitals, ofce buildings andlibraries. For several decades the city of Helsinki has done a greateffort to save energy and to achieve better energy efciency.

Helsinki pilots for Save Energy project are two comprehensiveschools. The key objective of the Helsinki pilot is to improve theenergy efciency at the Ala-Malmi school (built in 1965, with anarea of 7.000 m2 in three buildings, 300 pupils and 50 teachers) andPihkapuisto school (built in 1989, with a total area of 5.100 m2 in a

single building, 220 pupils and 25 teachers), with the support of thedeveloped ICT system providing the display information for differentuser groups with the real time measurements and the calculatedindicators of the energy consumption, savings and internal airquality conditions originated from the several pilot applications.

Following the Living Lab methodologies and based on technicalenergy evaluations and continuous discussions with the users andtechnical experts, different application areas of energy efciencywere identied; lighting and energy consumption applications atclassrooms and at the buildings entrance hall, energy consumptionof the whole school and the gym HVAC systems and energy efciencyof the kitchen operations, energy and consumption at normalclassrooms and PC classrooms.

Based on the test applications at these schools, the target was setto nd the functional model and best practices to be exploited in theother schools and public buildings. For example energy efciencyimprovement and more exible air quality control by the intelligentEC-motor based HVAC systems at the gyms and behavioural changeon energy efciency from the operative personnel at the kitchensusing the high power professional kitchen equipment were identiedas the most important goals to achieve the achieve very good energysavings.

The approach at the Helsinki pilot is to measure in real time allthe relevant energy information on the electricity, heat and waterconsumption; using the new high-tech wireless sensor networksystem, transferring the data from the existing building managementsystems and from the separate transferable measurement units.

All the measurements are collected to the virtual server generatingthe instructions to save energy and the simple and user-friendlyinterface displayed in LCD screens to the users of the schools(kitchen personal, janitor, teachers, pupils and technical experts) inorder to achieve the permanent awareness of behavioural change insaving the energy on these users.
