PERFORMER aims to develop an innovative and comprehensive solution towards improved building energy management & guaranteed energy performance.
PERFORMER will deliver a comprehensive energy performance assessment framework, including a set of performance assessment methodologies along with a suite of adapted and integrated off-the-shelf tools (e.g. energy simulation software) that factor in a high level of sensitivity of the building to its intrinsic attributes as well as the internal and external environment.
PERFORMER will address the needs of stakeholders across the energy value chain (builders, contracting owners, occupants and ESCOs), embedded in a dedicated quality process ensuring the strict adherence to targeted actual energy performance.
As a result, PERFORMER will contribute to drastically reduce the gap between expected and actual energy performance and promote the energy performance guarantee approach.
PERFORMER results will be validated on four demonstration buildings in France, United Kingdom, Spain and Poland. These demonstrators will be used to assess energy and environmental benefits of the new methodology and also to validate the framework and technologies for the concept to be easily replicable throughout countries with different climate condition variations across Europe.
PERFORMER aims to devise a holistic (total lifecycle, multi-aspects, context-based) building energy monitoring methodology that factors in appropriate energy performance indicators, information models, and simulation tools, to achieve building energy performance targets.
The main objective of the PERFORMER project is to develop, install and finally assess energy and environmental benefits of an innovative integrated concept for the monitoring and evaluation of building energy performance, towards energy performance guarantee.
PERFORMER’s technological objectives are:
- To devise a holistic building energy monitoring methodology that factors in appropriate energy performance indicators, information models, and simulation tools, to achieve building energy performance targets.To specify and assemble a configurable prototype “Energy Instrumentation Kit” to be used to establish energy performance accounts during operation and retrofit / post-retrofit stages.To specify, adapt / integrate and deliver a comprehensive framework for in situ assessment of building intrinsic performance of the envelop.To specify and prototype a secure and PERFORMER (monitored) data storage and simulation facility that can be hosted either in-house (on a local server) or outsourced and ported on a cloud / high performance computing infrastructure.
The project processes and demonstration objectives are:
- To stress test (i) the “Energy instrumentation kit in a box”, (ii) the Energy Simulation Environment, and (iii) the data storage and computing infrastructure in the context of the four selected demonstration projects, identifying limitations and areas of improvements for further refinement and consolidation.To test and validate the holistic building energy monitoring methodology in the context of each selected demonstration project articulating common attributes as well as general and unique features with a view of ensuring scalability and EU wide application.To locate the proposed methodology within the procurement path and project delivery lifecycle applicable within each participating countryTo establish a live repository of historic and real-time monitored data of the demonstration buildings accessible using a simple interface / functionality for testing and validation/assessment purposes.
The project assessment, replication and concept awareness objectives are:
To deliver knowledge transfer and embedding related activities, via the elaboration of a PERFORMER replication guide, to ensure results uptake by industry across Europe.To initiate adapted CPD (Continual Professional Development) training courses to pave the way to a new generation of energy responsible and aware skilled building professionals in the field of building energy capable of addressing / implementing EU and national energy reduction targets.To actively participate in standardisation activities at international (for example CEN TC 350, ISO TC 59 SC 17 and 14) and national levels (for instance Part L in the UK) exploiting existing EU channels.
PERFORMER project demonstrators
At all four Pilot Sites similar approaches have been adopted, utilising as much of the existing sensor and data collection systems as possible then filling the gaps with new sensors. Data transmission from sites to the PERFORMER Data Warehouse has often proven more challenging than collection of data itself. However the project has benefitted from the opportunity of trying out numerous approaches at each site.
PERFORMER DEMO N°1 : Baltic Plaza Spa Hotel, Kolobrzeg, Poland
Existing equipment that was used at the Polish Pilot site includes:
- BMS connected fan coil controllers providing actual and set point temperatures in all apartmentsContact sensors on apartment windows and balcony doors to detect whether or not these are openSMOK Boiler Management module providing information on various heating system flow temperatures, boiler firing times and external temperature
Additional equipment that was installed is as follows:
- Electricity meters to measure energy use in apartments and electrical loads such as chillers, air handling units and kitchen areasPulse counters for existing gas meters and some existing apartment electricity metersHeat meters to measure heat delivery to ventilation units, the spa pool, jacuzzi and domestic hot water from centralised boiler plantroomSaia Burgess open-protocol components to collect, store and transmit data from new and existing sensor systems.
Data is now being collected on a daily basis by the existing Bascom BMS and the new Saia system then collated and sent directly to the PERFOMER Data Warehouse each day.
Baltic Plaza Hotel (Kolobrzeg, Poland): The pilot meets all building regulations regarding energy use reduction. All devices working in the hotel are armed in elements getting back energy already used. Approximately 30 % of light source holders are LEDs. Electricity uses represent 75 % of all energy use in the building. The challenge in the building is further reduction of energy uses, especially electricity.
Demonstration challenge: The main problem in the building is further reduction of energy uses, especially electricity.
The PERFORMER project offer the opportunity to test two energy management systems:
- create and develop an electricity system control, which will be able to reduce power stroke effects.provide a model able to cooperate with already existing BMS (Building Monitoring System).
See the hotel website.
PERFORMER DEMO N°2: Hotel De Las Letras, Madrid, Spain
Hotel De Las Letras already had two systems with extensive sensor networks, their Exeon BMS for comfort control and the iGreen energy monitoring system. The sensors from these systems that are being used for the PERFORMER solution include;
- 147 space temperature sensors and 32 flow temperature sensors plus volume, flow, humidity and pressure sensors and valve position sensorsAir conditioning system sensors19 electricity sub-meters plus gas sub-meters and water meter pulsed output loggers
Due to the already extensive existing sensor networks new equipment has been limited to:
- Heat meters to separate heat energy for domestic hot water and space heatingWater meter to measure DHWS useElectricity meters to measure chiller electricity useCO2 sensors to measure air quality
All the new sensors are connected to the existing BMS or iGreen system and from these data is collated and transmitted to the PERFORMER data warehouse automatically each day.
Hotel de Las Letras (Madrid, Spain): The aim of the project is to improve energy management through a system which will enable to detect latent and abnormal consumption of electricity, gas and water.
Demonstration challenge: The building is located in a dense urban area: a specificity is that the building is included in the city’s heritage register and dates back to 1917. It was designed by architect Cesáreo Iradier as the home of the Count of Artaza, and was renovated for use as a hotel in 2005 by architects Virginia Figueras and Franco Corada.The PERFORMER system give the maintenance chief’s information necessary to detect latent and abnormal consumption of electricity, gas and water. Detectors and analysers are installed at critical points of consumption, especially in the outdoor Jacuzzis, and must be working to client availability. Control of the points of intensive consumption, will help the hotel to implement energy saving measures. Since the hotel is a historic building, this system was chosen because its installation must take into account a non-intrusive rehabilitation. The challenge is to achieve 20% savings by changing occupants’ behaviour.
In addition, the hotel manager has been informed about the necessary financial information related to energy consumption: it will help her to make decisions about, for example, the use of function rooms which are currently out of control.
PERFORMER DEMO N°3 : St Teilo’s Church in Wales High School, UK
As a new building the UK pilot site already had a large number of sensors connected to its Siemens BMS over a KNS network. It also had some existing equipment that was not functioning correctly and had to be replaced. Existing equipment that is being used includes:
- Temperature sensors installed in almost every room, various sensors collecting flow, volume, temp in the Boiler RoomElectricity, gas and water fiscal and sub-meters plus heat meters in heating plant roomElectricity meters to measure chiller electricity useIndoor and outdoor temperature, internal CO2 and occupancy sensors plus heating valve position in almost every room
Additional items that have been installed at the UK pilot include:
- Heat meters on heating zones to measure heat delivery to building wingsElectricity sub-meters for roof top cooling and ventilation plantSmart electricity meter for solar PV systemAdvanticsys data collector and wireless bridges to collect installed heat meter dataWeather station including cloud sensorWindow contact sensors to determine if window is open/closedPERFORMER Box and wireless occupancy and electrical plug-load sensors
Data handing at St Teilo’s is quite complex and includes daily transmission of data from the BMS database, Advanticsys data collector, Council energy database and PERFORMER Box to the PDW.
St Teilo’s Church in Wales Secondary School (Cardiff, UK): The pilot is a new build faith secondary (11-18) school which endeavours to exceed existing sustainable design principals and has renewable supplies as part of design. As the building is new, gaps between design performance and actual performance has yet to be measured.
Demonstration challenge: Improve the potential of building to automatically manage itself with a view to:
- (i) achieving energy savings by powering down unoccupied rooms – a common problem in buildings such as this where many rooms have occasional use, and staff/pupils do not have control over local systems.(ii) ensuring sensor and system resilience in an environment where controls can be easily tampered with. Also a 50kW roof-mounted solar photovoltaic panel system and a biomass boiler for space heating are present in the building; the system needs to manage energy from these systems in addition to grid supplies.
Multiple sensors will be used to assess a wide range of parameters including: occupation of rooms, lighting, temperature, ventilation and energy generation from the solar PV and biomass boiler systems. These parameters will produce a model, which will allow assessment and control of the building’s energy performance on a continuous basis.
In March 2014 thermal envelope testing was carried out in a small section of the school while it was unoccupied for a week. The school makes an excellent test facility as almost every room has temperature sensors installed and the data is collected through the BMS. Further monitoring will be undertaken during the deployment phase of the PERFORMER hardware/software through this monitoring will be carried out in the background while the school is operational.
Actual energy data of the demonstration site can be found on Carbon Culture.

PERFORMER DEMO N°4: WOOPA, Lyon, France
The French Pilot Site presents a challenge for the PERFORMER solution as it includes a number of different energy generation plant and shares a plant room with a neighbouring apartment block. The WOOPA office itself has a Trend BMS which all existing sensors are connected to. These include:
- Mains gas and electricity meters, oil flow meter and PV generation meterSub-meters for Co-gen electricity generation, DHW water and electricity for main plant, lights and small power.Space temperature sensors and HVAC temperature and flow sensors
Additional equipment that has been installed at WOOPA includes:
- Qualisteo NIALMS solution to monitor electrical loadsPERFORMER Box & EnOcean environmental sensors, including temperature, CO2, illuminance (lux level), motion, door and window contact sensorsHeat meters to measure heat generation from oil co-gen plant and biomass boiler and heat delivery to office heating circuitNew electricity sub-meters to replace existing faulty meters from original construction
Data transmission at WOOPA is split into 3 separate routes. Data from the Trend BMS, including new electricity sub-meters and heat meters is sent directly to the PDW. Data from the Qualisteo NIALMS is sent separately to the PDW from the NIALMS data collection system at WOOPA. Finally data from the EnOcean sensors is collected locally by the PERFORMER Box then transmitted to the PDW.
WOOPA office building (Lyon area, France): Woopa is a positive energy and zero carbon building, designed throughout 3 different pillars: 1. Use of bioclimatic technology: thermal and visual comfort, strengthened insulation, glass areas optimisation. 2. Use of efficient and high energy performance systems: active slab. 3. Use of renewable energy : local production of electricity, cogeneration, PVs. The project aim to evaluate the magnitude of electricity use in office buildings.
Demonstration challenge: Evaluate the magnitude of electricity use in office buildings.The main interest is to demonstrate PERFORMER’s capability to provide fast and accurate energy-related answers for the facility manager. In particular, the coupling between NIALMS (Non-Intrusive Appliance Load Monitoring System) and the BEMS (or any other additional sensors inside the building) will be also investigated. The extension of NIALMS to other uses (such as the gas consumption) in office buildings will also be explored. Fault Detection and Diagnosis will another key component of the analysis deployed and tested on the Woopa building.
The office building WOOPA is occupied by 4 design offices (QuadriPlus group) : COGECI, KATENE, ETAMINE, PROCOBAT and a bank. KATENE was in charge of the design office. ETAMINE was the design office in charge of the HQE certification of the building. WOOPA building main characterization:
• 500 users,
• 11 000m²,
• 7 floors,
• Year of the construction : 2011,
• WOOPA building is a BEPOS (NZEB) building,
• Centralized heating systems,
• BEMS TREND: 320 data recorded every 15 min.
The Woopa building’s users’ behaviour is key:
• As their behaviour can have a negative impact on the building’s performance, they cannot access the building’s thermal system. The lighting system is smart, self-monitored and adapt the “artificial” lighting according to the natural light.
• Return On Investment has never been the purpose as co-owners’ prerogative is to achieve and maintain a zero carbon level : occupants and owners strive to maintain the building’s good energy performance level, which means that they also have to make some “sacrifices” like maintaining the indoor temperature at 19 °C, what they find quite uncomfortable in winter.
