Favorite SYMPOSIUM: “The Building as the Cornerstone of our Future Energy Infrastructure – The importance of dynamic and real data for reliable assessment”, 10-11 April 2019, Bilbao, Spain

In the transition towards a new energy system, based on minimal carbon use and circular economy principles, the building is the cornerstone of the future energy infrastructure. Energy use in  European buildings is still around 40 % of the total final energy use. Decarbonisation of power and heat are high on the agenda of EU Member States. Present initiatives by governments for a proper energy transition …. read further.

Favorite Outcome of the Dynastee Workshop of 11 April 2018.

With over 80 participants, the workshop on Building energy performance assessment and quality assurance based on in-situ measurements that took place on Wednesday 11 April 2018 has become a great success. The aim of the workshop was to bring closer together on this topic, research from IEA-EBC Annex 71 and standard writers from CEN TC89-WG13. People from industry, research and academic participated to lively discussions during both sessions on the topic of in-situ measurements and assurance of quality. All six presentations can be downloaded from the agenda below.

Welcome to the workshop – Luk Vandaele (DYNASTEE)

Annex 71: Status of the project IEA project Annex 71 after the expert meeting – Staf Roels (KULeuven, Operating Agent Annex 71)

Session 1 – Assessment and assurance of energy consumption in the building sector

  • Standards dealing with quality aspects for in-situ measurement of the energy performance – Richard Fitton (Salford University and CEN TC 89 WG 13)
  • Panel discussion with Ross Holleron (Knauf Insulation) and Guillaume Pandraud (Isover Saint-Gobain) moderated by Hans Bloem (DYNASTEE, JRC)
  • Questions and views from the audience

Session 2 – On site measurements in the context of the regulatory assessment of the energy performance of new buildings

  • What are challenges and opportunities when using measured consumption (and indoor climate data) for compliance checks in EPBD context? – Peter Wouters (BBRI, INIVE)
  • Energy performance assessment of buildings using measurements: experience from smart meter data analysis – Eline Himpe (Ghent University)
  • Role play on enforcement aspects in case of non-compliance – Peter Wouters
  • Questions and views from the audience

Closing session– conclusions by Staf Roels and Liesje Van Gelder (BCCA)

Favorite 11 April 2018, Brussels – Building energy performance assessment and quality assurance based on in-situ measurements

In order to reduce the energy use of buildings, policy makers impose stringent requirements with regard to energy performance of new buildings and renovated buildings, and the use of renewable resources. Most compliance checks and labelling of the energy performances of buildings are done in the design phase by calculating the theoretical energy use. But, despite regulation and policy enforcements, monitoring of actual energy performances reveals in many cases a significant gap with theoretically designed targets. The currently observed performance gap, in combination with the increasing integration of innovative systems such as intelligent elements, low energy technologies, active solar systems, … accentuate the need to develop reliable methods and procedures that can be applied on site to assess the actual performance of buildings.

This request for onsite quality assessment is also clearly visible in several initiatives taken in different countries. Current assessment methods, however, often focus only on limited aspects, such as the building air tightness, or the quality of ventilation systems,… while overall methods based on in-situ measured data remain sparse. A better prediction, characterization and quality assurance of the actual building energy performance is essential to realise the world wide intended energy reduction in building communities and systems. Quantifying the actual performance of buildings can only be effectively realised by optimized in-situ measurements combined with dynamic data analysis techniques.

The IEA EBC Annex 71-project on ‘Building Energy Performance Assessment Based on In-Situ Measurements’ aims to make the step towards monitoring in-use buildings to obtain reliable quality checks of daily building construction practice to guarantee that designed performances are obtained on site.

This workshop will focus on the development of methods for the assessment and assurance of energy consumption in the building sector and potential applications in the context of the regulatory assessment of the energy performance of new buildings.

The workshop is organised by the DYNASTEE platform (www.dynastee.info), facilitated by INIVE (www.inive.org), following the IEA Annex 71 4th international expert meeting in Brussels.

The seminar is open to all professionals interested in quality assurance of the actual building energy performance.
