Monday April 18th
- 9.30 welcome coffee
- 10.00 Welcome and aim of the workshop Staf Roels, Building Physics Section, KU Leuven, Belgium
- 10.15 Presentation of IEA EBC Annex 58 outcome Annex 58 core group - For four years, international experts from all over the world have been working together in the framework of IEA EBC Annex 58 on the topic of ‘Reliable building energy performance characterization based on full scale dynamic measurements’. The major outcomes of this project will be presented as possible starting point for the new proposal.
- 10.45 Bridging the gap between predicted and actual performances through measurements and quality checks along building life Guillaume Ansanay-Alex, Researcher & Project Leader at CSTB, France - Discrepancies between predicted and actual performances of buildings are still observed for a large part of the building stock. We believe that bridging this gap can be achieved by applying a quality approach based on an optimized measurement and verification plan, and including at each stage of building life a set of quality checks able to break down the discrepancy into its main sources.
- 11.15 Towards zero-energy districts – opportunities of characterization in modeling and optimization Dirk Saelens, Building Physics Section, KU Leuven, Belgium - With an increasing penetration of distributed and intermittent renewable energy sources in an energy efficient building environment, demand-side flexibility and energy-exchange between different actuators show significant potential to further increase the energy efficiency on a district level while avoiding potential grid stability issues. An important source of demand-side flexibility is identified to be the embedded thermal mass of building. By intelligent, active control of the indoor temperature this thermal mass can be activated to support such demand-response programs. To exploit this potential, a reliable method to describe the energy state of buildings and their installations is essential. In this lecture, on the one hand a bottom-up, multidomain simulation framework to assess the impact on a neighborhood level of energy efficiency measures taken at the individual building level is presented. On the other hand, a generic characterization method is shown to assess the potential for active demand response using the thermal mass for new as well as existing buildings.
- 11.45 Building Energy Performance and Location -JRC Energy & Cities project; from building to urban area Hans Bloem, DG Joint Research Centre, European Commission, Italy - Presented will be the recently started Energy & Cities pilot project that deals with performance assessment of buildings. A six level approach is discussed that deals with different methodologies using different data resources. A top-down empirical approach starts from administrative data (INSPIRE harmonization of data) resulting in performance label values. A bottom-up approach starts from calculation rules that can be simplified up to detailed standardized calculation method. The validation of the different methods relies a lot on measured data arriving from field experimental work or from regular metering data. The issue of big data handling in relation to complexity and uncertainty will be discussed also. The importance of location issues related to building energy performance is highlighted in the example of energy integration in the built environment.
- 12.15 sandwich lunch
- 13.30 Some perspectives for the use of smart meter data - Henrik Madsen, Peder Bacher, DTU Compute, DTU, Denmark - This talk describes some of the perspectives for the use smart meter data for identifying the energy efficiency of buildings. It will be described how values for the energy performance characteristics can be identified by filtering out the influence of occupancy behavior. Similarly it will be illustrated how meter data and methods for data analytics can be used to cluster and characterize the diurnal profile of energy consumption related to the occupancy behavior.

- 13.30 Progress on standards for in-situ measurements for building and building components within CEN TC89/WG13 Jon Denyer, Convenor CEN TC 89 WG 13 (To be confirmed) - Reported will be the latest advances in defining the methods for in-situ measurements and related analysis methodology.
- 14.00 DYNASTEE – Network of Excellence - Luk Vandaele, Belgian Building Research Institute, Belgium - In the previous project Annex 58, the DYNASTEE platform was responsible for the development of the Network of Excellence. This was done through a series of seminars, the organization of a yearly training session in dynamic analysis methods, a newsletter, the website, … DYNASTEE would like to enhance the interaction with the broader community of potential users of the research results by enhanced tools and facilities for exchange and dissemination.
- 14.15 Training scientists and the potential of e-courses: sharing experience on a successful JRC case Philip D.P. Taylor, European Commission JRC, Belgium - Analytical measurements play a crucial role in science and society at large and many students are taught basic understanding and practical skills in the curricula they follow. Today, when important decisions depend on such measurements (e.g. regulatory, trade, production …) often they can only be carried out in accredited testing laboratories. In 2001, the JRC set up a Continuous Professional Development (CPD) programme called TrainMiC® (https://ec.europa.eu/jrc/en/trainmic), targeting those testing laboratories. It is based on developing common shareware training material (via an editorial board) as well as training local trainers, to enhance outreach. The JRC fostered the development of an International Master programme, called Measurement Science in Chemistry, and runs a very successful annual summer school. Lately, both the CPD and student programmes, have been gaining experience with e-course delivery of courses. The talk will explain how this is done, what are the benefits as well as the challenges. First experience shows that e-course delivery has great potential and can be blended into other forms of training/teaching (e.g. DYNASTEE Summer School).
