Commercial and industrial buildings need stable indoor climate, but conventional HVAC systems often use more energy than the operation can justify. Cutting consumption only works if comfort, air quality and reliability stay intact.

This case looks at energy-efficient ventilation specified for day-to-day operations rather than a one-off efficiency claim. Commissioning, operator training and monitoring decide whether the designed savings appear in the energy bill.

GII’s work in this area connects German environmental engineering with building operations: the technology has to be installable, tunable and understandable for the facilities team that inherits it.
