C/2 was founded by David Ellowitz, an industry veteran who has preempted the rise of sustainability engineering and Data Center HVAC design.Over our careers, we advised and designed for some of the worlds most sophisticated technology companies and academic institutions.

Don't just design, deliver.

C/2 is predicated on the idea that bleeding edge HVAC implementation gets stuck at the concept phase.We partner with architects, engineers and contractors to deliver a functioning implementation, on-budget, while still delivering on elegant and bleeding edge sustainability and design.
