Favorite Outcome of the Summer School 2018

Outcome of the 7th Summer School on “Dynamic methods for whole building energy assessment” organised by the INIVE-DYNASTEE and PSA-CIEMAT in collaboration with CIESOL (Joint Centre University of Almeria-CIEMAT dedicated to research in Solar Energy and its applications), in Almería, Spain. The focus has been more on pragmatic application of developed dynamic calculation techniques to support the analysis of building energy data that is of high importance and can give potentially high value information to utilities and end-users. The focus this time has been on increased complexity and variability, and several approaches have been applied to benchmark data.

A follow-up Summer School has been discussed which may take place in Summer 2019 again in Spain. Follow our organisational progress at the DYNASTEE web-site

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.

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.

Favorite Outcome of the Summer School 2017 in Granada, Spain

A warm welcome to the participants by Josemaría Manzano Jurado, director of School of Architecture from the University of Granada (founded in 1531) and Delfina Bastos González, academic secretary of the School was followed by a tour in the beautiful renovated old building in the centre of the city.

After 5 very successful editions of the Summer School on “Dynamic methods for whole building energy assessment” this time the focus was on pragmatic application of these dynamic calculation techniques. The main purpose of this summer school was to train a methodology for evaluation of measured data. Five enthusiastic lecturers have presented methodologies in more than 10 presentations for assessing the heat transfer characteristics of building envelopes using data for hands-on exercises. During the summer course, information on relevant software has been given. For the practical exercises the software tool LORD has been applied on benchmark data as well as routines in the R-environment. More than half of the participants submitted prior to the course their homework which revealed that most of them have problems with assessing the thermal capacitance. This was the reason for a special lecture on how to deal with techniques for separating the static aspects from the dynamics. Discussed has been a more advanced course as a follow-up of this Summer School School that may take place during the summer of 2018.

For the social mid-week event, a visit to the Salobreña Castle on the Mediterranean coast was organised followed by a dinner with all participants and lecturers on the terrace of a typical Spanish taberna.
