From here I wanted to congratulate the entire Zero Energy team for their approach to the platform and the distance learning system, which was previously appreciated as a way of being able to combine working life with continuous learning. With COVID, it has been shown to be very effective to avoid attendance. Very well-prepared classes, always interesting topics and an exciting world to delve into with all the available material. Highly recommended, and for. My part I will continue to enjoy all the training you offer.

I really likes doing the Certified Passivehaus designer course in online dictated by Zero Energy. It has given me the right tools to be able to design and build with criteria and awareness. The online modality was very useful since living in a different country, with a different time zone and a full time job, the Zero Energy system allowed me to watch videos of the classes as soon as they were available and play them in my time and on my schedule., with the possibility of taking notes at my own pace, continue with the notes, go back and forward the videos according to what is necessary. A very interesting point is that the videos had a possibility of being reproduced at a higher speed, which made it very useful if you had already read the books and wanted to review concepts, saving time. Zero Energy’s online portal to watch course videos, ask questions and receive answers is very simple and easy to use with a nice aesthetic. I highly recommend this online course for all of us who have a compressed schedule. 100% recommendable.
