The Coltbaan 2 facility in Nieuwegein comprises of 2.200 m2 of datacenter space and associated office / training and meeting space.
The building is a former government developed data center (rijksgebouwendienst) for the social security bank (SVB). In that time (1992) considered as a unique secure design. The surrounding water not only secures the site but could also be used for "green" cooling techniques. Furthermore the substantial site (0.6 ha) serves dedicated car parking and flexible plant solutions.

Technical installations

The technical installations are approximately 18 years old. Some elements have already been replaced. Dependent on client needs, the installations of the data centre could be upgraded.
Two upgrade scenarios have been analyzed:
1) Upgrade to last for a 10 year period.
2) Upgrade the installation to new market - and energy efficient standards
In both options parts of the installations can be re-used.
The main power supply is 1.7 MVA. It is possible to upgrade the power connection to 5 MVA. With this upgrade the data centre power supply is more than 2.2 kW/m2.
With a market standard of 1,5kW/m2 the current power connection is sufficient for the available 955 m2 data space and the training centre of 548 m2.
Dependent on client needs different solution could be implemented. With or without an upgrade of the power connection. UPS system and back up generators are available.
Security of the datacenter is in place with access control at the building entrances, CCTV installation and 24 -7 on site security. Fire safety is controlled by fire detection system and gas suppression for technical rooms.
Cooling systems can either be used or upgraded to more energy efficient standards.
