Office and co-working space

Designing an office building today is like creating a time capsule.
It must contain advanced technologies, create a positive environment and influence workers’ productivity, is easily transformed for various uses and be carbon neutral or may produce a surplus of energy.
There are two areas where our engineers obtain the experience and exercise their creative minds: new office centres and hubs, and reviving and upgrading of existing building systems.

The former factory building that was restored and converted into offices in 2006. The building was heated via portable electric heaters that consume a lot of energy and do not provide comfortable environment. CDI proposed to install three-pipe variable refrigerant system (VRF) for heating and cooling, which provides economically precise, individual comfort control to multiple spaces. System operates with minimum energy usage and low maintenance cost, as service required to the zones that need it, which allows for less required maintenance. Cooling for server rooms and electrical installations will be upgraded to the modern standards. In addition, ventilation will be provided to the basement units and heat recovery to be installed.
