Certified Data Centre Environmental Sustainability Specialist (CDESS®)

More data centres are being built, driven by the explosion of data and the processing power required for IoT (Internet of things) sensors and AI (Artifficial Intelligence). The percentage of total power consumption by data centres is growing in parallel. It has become vitally important that data centres are optimized for energy efficiency and designed for environmental sustainability.

>> Available in Danish <<

Virtual Course

This course is held virtually with live instructors together with students from all over the world via your own PC. The course consist of a combination of lectures and question-and-answer sessions to discuss your specific needs and issues experienced in your own environment. The exam can be taken as an online exam no later than 7 days after the course is held. You will receive a voucher for the online exam.

Online Course TOD

You can also complete this course as "Training on Demand", which is EPI's online version of the course. Please contact us for further information.


Participants must have at least one to two years' experience in a data centre or facilities environment. The CDCP® is highly recommended. The CDESS® will discuss data centre facility aspects and without the CDCP® or equivalent knowledge, the participant may not be able to gain the full benefits of the CDESS® training.

Participant profile

The primary audience for this course is any IT, facilities or data centre professional who works in and around the data centre and has the responsibility to achieve and improve efficiency and environmental sustainability, whilst maintaining the availability and manageability of the data centre.
