The EBC Annex 80 held its fifth Expert Meeting on October 14^th and 15^th at Politecnico di Torino. For the first time in years, 24 participants from 9 countries attended the meeting in person. The meeting was held as hybrid meeting as not all participants had been allowed to travel to Italy. 

Results

The annex in the third year of its working phase continues to contribute to resilient cooling in the various fields of its mission statement. The definition and development of fundamentals like the definition of resilience and thermal conditions or generation of future weather files for building simulation is being finalised. While the assessment of cooling technologies is in progress the last phase of the annex will also focus on pushing technological boundaries.

The definition of key performance indicators of resilient cooling, an important task of Annex 80, has progressed substantially. Three categories, each consisting of three levels of indicators expressing their specificity have been defined as following

• Comfort & health metrics
• Energy & environment metrics
• Socio-economic

Metrics for carbon emissions as well as exceedance hours for humidity will also be considered. During the upcoming months the collection of metrics will be finalised and shall be tested in the technology assessment, which will be carried out through dynamic simulations. For that purpose, the simulation task group created a methodology guideline to ensure high-quality comparable results across the numerous participating institutions. 

Dissemination

Members of the annex took the decision to actively contribute to upcoming conferences in 2022. The AIVC conferences in Athens and Rotterdam and the COBEE conference in Montreal, for instance, offer valuable opportunities to disseminate and share findings generated in the annex. It is planned to organise topical sessions on “resilient cooling” to foster the exchange with international experts of the scientific community. The Annex also published the following paper since last expert meeting:

• “Resilient cooling strategies – a critical review and qualitative assessment” Chen Zhang et al, Energy and Buildings (https://doi.org/10.1016/j.enbuild.2021.111312)

Started in March the “Advisory Board of Practitioners of Resilient Cooling” meets on a regular basis to share their knowledge and experience on topics such as the definition of resilience as regards cooling, key performance indicators and metrics of resilient cooling and future weather data for building simulations. The board will meet again in spring and autumn of 2022 to exchange on the latest advances of resilient cooling technologies.

On April 25^th and 26^th Annex 80 members will meet again for their 6^th Expert Meeting. It will take place in Copenhagen, Denmark.
