Visit us at the 13th Spanish Passivhaus Conference

The Passivhaus Building Platform (PEP*) conference will be held in Murcia from 21st to 23rd of October.

Come and visit us at the 13th Spanish Passivhaus Conference which brings together professionals, companies and experts in the field of energy efficiency in the construction industry. The conference will take place from 21st to 23rd October at the Catholic University of Murcia (UCAM). You will find us at stand 5.

During the event we will show you how to fit our solutions in several installation sessions.

Don't miss the intervention on the first Passivhaus office building in Catalonia with Griesser exterior venetian blinds and a Solar Tracking system on Friday, 22.10.2021 between 09h and 10h10.

The conference programme includes an institutional day, technical sessions and a day of visits to Passivhaus projects in the region, scheduled for Saturday, 23 October. Murcia as a host city is particularly suitable renovation projects and solutions in warm climate zones.

For Bruno Gutiérrez Cuevas, President of the PEP "Giving visibility to Passivhaus new build and renovation projects, especially in warm climates, is very important to us, and holding the event in an Autonomous Community that is ideal in this respect creates a unique opportunity to put the spotlight on the relevance of the standard, whatever the climatic conditions of the territory in which it is located. We look forward to sharing first class projects and experiences with our partners and the public at large to further promote near-zero energy buildings certified under the passivhaus standard in Spain".

One such project is the 950 m² offices of Coatresa, an expert in non-stick and anti-corrosion coating solutions in the province of Barcelona with Passivhaus Classic Certification. The use of our Lamisol 70 Fix external venetian blinds with a KNX home automation system and solar tracking addresses the challenge of overheating and reduces energy consumption considerably.

At the same time, this solution allows visual contact with the outside, letting natural light in.

If you want to know more about this project, attend the technical seminar - innovation block - on Friday, 22.10.2021 at 09h.

To attend the assembly and installation sessions of our products, we will provide a link for registration in the near future through our social networks.
