“NEW TOOLS TO REDUCE THE ENERGY PERFORMANCE GAP“ Workshop Context
At the “New tools to reduce the energy performance gap” workshop at SP’2016, five EU projects aim at providing new services, tools and methodolo-gies narrowing the lacks and the inconveniences of current solutions will present their interrelated solutions. The proposed solutions target a large audience of cus-tomers (ESCO, facility managers, energy managers, maintenance managers, building management system providers, technology or services providers, building owner and building occupants). They are all based on the linkage between build-ing performance models and measured data coming from operational Building Management Systems. National regulations on construction in Europe are de-signed to support the Energy Performance of Buildings Directive, by leading to im-proved energy performance in new buildings, extensions to buildings and refur-bishments, and the revisions to building regulations have indeed led to higher lev-els of insulation and more efficient HVAC systems. In practice, however, the im-provements to efficiency on paper have not been fully achieved in practice. There is a gap between the performance that is sought and the performance that is real-ised. Errors in the construction and commissioning of the building fabric and ser-vices have had an impact, but occupiers are also using buildings in ways that dif-fer from what was originally envisaged. The result is that energy consumptions of buildings often exceed design energy requirements. The performance gap can of-ten lie in the range 150%-250%. This has implications for running costs, national energy supply and climate change.
“NEW TOOLS TO REDUCE THE ENERGY PERFORMANCE GAP“ Workshop Agenda
Five European H2020 funded projects, HIT2GAP, TOPAs, QUANTUM, MOEEBIUS, and TRIBUTE will work to provide new tools and methodologies to minimise the gap between the predicted and the actual energy usage in buildings and blocks of buildings. The workshop aims at initiating clustering around this topic and discussing the solutions developed as part of the projects.

Round table 1: dissemination, exploitation plans and specific ways of collaboration to maximise impact (eg standardisation) (45’)
Round table 2: implementation of the project (User driven, validation procedures for TRLs…) (45’)
Conclusions and closure (10’)
Workshop Co-Chair: QUANTUM
The objective of QUANTUM is to develop and demonstrate pragmat-ic services and appropriate tools supporting quality management in the design, construction, commissioning and operation phase as a means to close the gap be-tween predicted and measured energy consumption in European buildings. The project will integrate different innovative ICT-driven tools supporting the quality management process into building and energy services, and will apply them to a representative set of European buildings. The result of this project will be a com-prehensive QUANTUM quality management platform integrating tools, services and processes.
The estimated average gap between calculated and actual energy performance of the European building stock is 25% for energy performance and 1,5% for comfort perfor-mance (as scored by building occupants). Comprehensive research has shown that faultily commissioned and operated building management systems are a main cause for this gap mainly caused by the lack of ap-propriate and coherent quality management systems for building performance. The objective of this project is therefore to develop and demonstrate pragmatic ser-vices and appropriate tools supporting quality management in the design, construction, commissioning and operation phase as a means to close this gap in European build-ings. The project will integrate different innovative ICT-driven tools supporting the qual-ity management process into building and energy services, and will apply them to a representative set of European buildings (taking into account different climate zones and different energy services).
The result of this project will be a comprehensive QUANTUM quality management platform integrating tools, services and processes. The partners will implement EU-wide dissemination activities to inform the stakeholders about the advantages of com-prehensive quality management systems for the building industry, and to promote the tools validated in the project. Stakeholders that will benefit from the results of this pro-ject include building owners, tenants, ESCOs, developers, architects, engineering and consulting firms, students and public authorities.
Aside from savings on the energy costs CO2 emissions will be reduced and employee productivity in buildings equipped with the tools and services will increase as well due to increased occupant comfort. From previous preliminary data and own estimations, the QUANTUM partners expect that the reduction in energy consumption achieved by coherent quality management for building performance to be more than 10%.
Within the duration of the QUANTUM project demo buildings will be analysed in two phases. The first three demo buildings are in Germany, Austria and in the Czech Republic. To generate an empiric data base 120 buildings will be also examined with the Comfortmeter in the first 12 months of the project.
Phase 1: Small-scale tools demonstration in relevant environment: In Phase 1 three build-ings will be selected for testing of tools ENA and CM (both on TRL6). The main goal is to test their applicability, technical interfaces, successful target definition, measurement and validation and ensure their readiness for the large scale demonstration that will follow in Phase 2. Important part of this phase will be detail building energy system analysis and definition of AFSs and KPIs and their subsequent implementation in ENA. 12 months will be dedicated to data collection and continuous monitoring and validation of implementation. Based on this data and gained experi-ences a helpful feedback will be provided to the tools developers, so that they can improved and adjust them before the beginning of Phase 2.
Phase 2: System prototype demonstration in operational environment: Phase 2 will focus on testing the previously defined process of QM for building performance and application of tools for usability in QM. Apart from the 3 buildings from Phase 1, at least 12 additional buildings will be selected to undergo the process of analysis, tools implementation and 12 months of operation.
This time all described steps will be made in accordance with the definition of process of QM and a particular type of service provided by a partner. Tools ENA and CM are expected to be on TRL7 in this phase. The goal is to obtain sufficient amount of verified data to be able to provide recom-mendations for future use and feedback to other WPs. According to the areas of expertise of the partners and their position in the building industry, the demo buildings will be grouped according to tools and services applied.
Within the project consortium there are companies (i.e. EA, E7, COWI, BRE) from different occupational groups like engineers, contractors or consultants. These companies want to include or already have included QM for building performance into their portfo-lio of service, which are: Commissioning in new construction and comprehensive refurbishment of nearly zero energy buildings (Partners involved: COWI, E7); Retrofitting of building systems (Partners involved: partially ENESA); Energy performance contracting (EPC) (Partners involved: ENESA); Recommissioning (Partners involved: E7); Facility Management; Environmental certifi-cation for buildings (Partners involved: BRE, E7).
Experiences gained during the Phase 2 will be exchanged and discussed among partners and finally transformed into best-practices recommendations. This output will be used as a base ma-terial for development of business plans for QM implementation and further improvement of tools and services.
The consortium strives to reduce the gap between predicted and monitored performance by applying a coherent quality management system (QMS) for buildings supported by three tools. Although the three tools are different elements in the project they work best together doing quality assurance. Different combinations of tools in buildings permit a flexible application in various project situations.

Workshop Co-Chair: HIT2GAP – Pascale BRASSIER, NOBATEK, FR
Graduated as engineer from the MATMECA Magistère in Bordeaux (Fr) in 1997, Pascale received her PhD in Mechanics from the University of Bordeaux 1 in 2000. After an 8 years’ experience in the non-destructive testing domain in the aerospace industry, she joined NOBATEK in 2012 as project manager in the field of building monitoring after a professional training on energy efficien-cy and techniques for building performances assessment. She is in charge of projects related to building monitoring and energy performance assessment of buildings and particularly involved in European and research projects.
HIT2GAP was established to develop an energy management platform which aims to reduce or eliminate the energy gap by providing, firstly, a data platform, to collect and store data about a building, and secondly, by modelling, to predict energy requirements with the aim of forecasting or benchmarking buildings, and thirdly, by the provision of modules to interpret data and present it in a user-friendly style, tailored for a range of au-diences. The platform will also welcome third-party modules, provided by small innova-tive companies for example, which can analyse or display data in an innovative way.
The actual energy consumption of buildings in Europe often significantly exceeds the expected energy requirements. This gap in energy performance can arise from con-struction errors but it can also result from differences between the way a building is ac-tually used and how it was intended to be used. An energy management platform could help to reduce this energy gap.Ach
ieving energy efficiency targets will be made much easier thanks to a new and inno-vative energy reporting platform.
To meet this ambitious objective, the HIT2GAP project will deliver:
1. A generic information platform with protocols for communication with devices and user interfaces
2. Building energy modelling, to establish energy consumption benchmarks3. A va
riety of tailored modules to inform users, energy managers and engineer.
The aims of the HIT2GAP project are:
1. to reduce the energy gap, focusing on the operation phase of buildings
2. to propose a new paradigm for the development of energy management plat-forms in buildings, integrating existing expertise and resources
to provide a smart platform which is marketable.
The partners of HIT2GAP are working together to provide a platform which is both generic and modular, which could be used in a wide variety of buildings and groups of buildings. It will include plug-and-play modules that are designed to inform users about the operational performance of their building(s), based on data collected at building level.
HIT2GAP modules will provide information to users of buildings to help them to re-duce energy consumption. The information could be provided in various formats, and those formats could be tailored to specific needs of building users. For some users, simple or engaging displays might provide the greatest impact on energy saving. For other users, more detailed information could be provided, to enable a strategic approach to be taken by those who are responsible for saving energy. Provision of information to users, in the right format, could help to close the gap be-tween actual energy performance and expected performance.
HIT2GAP PROJECT PLAN:
The HIT2GAP Project is divided into a number of Work Packages (WPs), each led by a partner organisation:
WP1 – Requirements, framework and methodology to perform energy savings from data treatment (APINTECH)

TOPAs will develop an open, cloud based platform of analytic tools to minimise the gap between the predicted and the actual energy usage in blocks of buildings. TOPAs is tar-geting to reduce the existing gap to 10% and approach additional energy savings in the pilot regions up to 20%.
According to the World Energy Outlook reports, buildings are the largest energy con-sumers in the western world with approximately 40% of total energy consumption con-tributing 30% to the total CO2 emissions. TOPAs will focus on reducing the gap from an operational perspective, hence supporting Post Occupancy Evaluation (POE). TOPAs adopts the principle of continuous performance auditing and considers not only energy use but also an understanding of how buildings are used and their climatic state (environmental & air quality), thus providing a holistic performance audit process through supporting tools and methodologies that minimise the gap between predicted and actual energy use.
TOPAs open platform will efficiently analyse large amounts of data from building to blocks of buildings, including existing building management and metering systems to op-timise energy performance and identify areas for improvement. TOPAs will link building performance (prediction) models with operational Building Management Systems (BMSs) and measuring technologies to improve both the accuracy of the prediction models and the in-use performance of the buildings.
TOPAs’s framework for continuous performance auditing will allow the better under-standing of the actual energy performance in and across existing buildings and facilitate continuous performance improvement based on real operational use. TOPAs will pro-vide decision support tools for building and facilities managers, owners and ESCOs to more effectively manage their site, providing visibility on how energy related decisions impact cost, occupant comfort and health and general management process. TOPAs will demonstrate the benefits of continuous auditing process through the use of the TOPAs solution under real operating conditions and scenarios in private and public commercial building blocks.
The TOPAs business offering contains four categories: Building System Integration, Real time Energy Optimisation, Energy Performance Diagnosis and Energy Management Ser-vices. These categories are detailed in D1.3, Section 2. Under these four categories were defined the following twelve use cases: Building Systems Integration o BSI-1 Neighbourhood Information Model Configuration o BSI-2 Building System Abstraction o BSI-3 BMS Policy Configuration Real time Energy Optimisation o REO-1 Thermal Regulation driven by Occupancy & Comfort o REO-2 Cost Aware Energy Regulation o REO-3 Thermal & Electrical Regulation for Blocks of Building Energy Performance Diagnosis o EPD-1 Fault Detection & Diagnosis o EPD-2 System Re-configuration Energy Management Services o EMS-1 Energy Prediction Modelling o EMS-2 Occupancy Modelling o EMS -3 Air Quality Analysis o EMS-4 Monitoring and Manage-ment of Energy Flows (excertpt from: D7.1: Validation Methodology Description )
TOPAs will enhance traditional energy performance related data sources (e.g. energy meters, temperature, humidity, weather etc.) with contextual sources such as occupancy models, equip-ment performance and air quality models to better quantify the performance gap.
TOPAs technological objectives includes:
KPIs – Enhance current common performance metrics and performance auditing processes for building and blocks of buildings to enable experience and knowledge sharing among stakeholders to firstly improve the replicability of energy savings for similar building typologies through a better base model and secondly investigate the most appropriate business models to foster growth in the energy services sector.
TOPAs technological objectives includes:
Open BMS approach – the integration of existing technologies to develop an open BMS platform that will efficiently analyse large amounts of data from building to blocks of buildings, including ex-isting building management and metering systems to optimise energy performance and identify areas for improvement.
TOPAs technological objectives includes:
Energy Prediction – The refinement and fine tuning of building performance modeling approach-es to accurately predict energy usage and close the gap between this and actual energy use through enhanced machine-learning approaches. It is envisaged that such models will assist in the identification of energy saving potentials, fault detection, and control optimisation within ener-gy performance contracts by providing an independent and accurate measurement and verifica-tion tool for Post Occupancy Evaluation (POE).
TOPAs technological objectives includes:
Model Predictive Control – Integrate enhanced building models with a continuous auditing meth-odology encapsulating live building performance measurements enabling a measurement based performance evaluation. Improving control and energy consumption at all levels of building opera-tion using Distributed Model Predictive Control (DMPC) approaches at building and district level that utilize the occupancy, air quality monitoring and energy prediction model).
TOPAs technological objectives includes:
Decision Support Tools – Provide decision support tools for building and facilities managers, owners and ESCOs to more effectively manage their site, providing visibility on how energy relat-ed decisions impact cost, occupant comfort and health and general management process.Gap
Reduction – Target a reduction in the gap to 10% as an initial benchmark and to progres-sively challenge this target throughout the project.
TOPAs technological objectives includes:
Energy Savings – Target additional energy savings in the pilot regions of 15% – 20%
