IEA SHC Solar Academy: Renovating Historic Buildings towards Zero Energy - Task 59

The International Solar Energy Society is pleased to host the first webinar of the IEA SHC Solar Academy Solar Academy for 2020 on the IEA SHC Task 59: Renovating Historic Buildings towards Zero Energy.

Task 59 addresses the renovation of historic buildings, increasing their comfort whilst significantly bringing down the buildings energy demand and CO2 emissions as well as keeping their characteristic values. Given the unique character of each of the buildings, a “standard solution” to fit every case cannot be identified, yet Task 59 combines considerable experience on specific cases available, which need to be evaluated, exploited and promoted.

In this webinar, you will be guided through real world renovation experiences - by building owners and design teams, who express their needs, concerns and experiences and the Task 59 experts who introduce the diverse tools which can help you in the decision and design process of an exemplary historic building energy retrofit project.

Q/A Session: The 90-minute webinar will include a 30 minutes Q/A session for the audience.

The webinar is organized by the Solar Academy of the IEA SHC Programme and hosted by ISES, the International Solar Energy Society.


Webinar presentations


Alexandra Troi

Alexandra Troi is co-founder and vice head of Eurac’s Institute for Renewable Energy and leader of the research group on Energy Retrofit of Historic Buildings as well as  the Operation Agent of Task 59. Alexandra's main fields of research are historic buildings & cultural heritage, energetic refurbishment of buildings and cross-discipline communication.


Walter Hüttler

Walter Hüttler as Subtask A leader of Task 59 will introduce you to the Historic Building Energy Retrofit Atlas, a compilation of inspiring best-practices. Walter is an engineer with a multidisciplinary background in social sciences and economy. He is managing partner at “e7 energy innovation & engineering”, consulting engineers based in Vienna, Austria. Before he worked for the Austrian Energy Agency and as research fellow and lecturer at Vienna University (IFF). Since 2015 he is lecturer at the FH Campus Vienna, University of Applied Sciences (study program Architecture – Green Building). Walter Hüttler has long and varied experience in managing projects in the field of energy efficiency in the building sector on national and EU-level and is the author of numerous energy and environmental studies.

Tor Broström

Tor Broström as Subtask B leader of Task 59 will show how the decision process following EN 16883 on sustainably improving the energy performance of historic buildings can help to identify the most appropriate renovation solutions and evaluating them in a holistic way. Tor is a Professor for Building Conservation at Uppsala University, Sweden. With a background in engineering, he spent most of his professional career in working with historic buildings. Tor is coordinator of the Swedish research program on energy efficiency in historic buildings and was chairman in the working group that produced the European standard in the same field.



Pavel Sevela

Pavel Sevela studied civil engineering and works as a scientific project assistant at the Energy Efficient Building department of the University of Innsbruck. In his scientific work Pavel combines his enormous practical knowledge in the design, planning and construction of sustainable buildings with theoretical research on interdisciplinary sustainability.

As Subtask C leader of Task 59 will present you a tool which can help you to at the same time to open up your mind, consider solutions you have not yet heard about, and at the same time narrow down the selection to the ones most appropriate for your building.

Daniel Herrera

Daniel Herrera as part of the Operating Agents team will show you how all the different steps presented were implemented in the specific case of  renovation of the Rainhof in South Tyrol/Italy.
