Summary

A new futuristic structure is rising toward the skies in the Utrecht Science Park. The National Institute for Public Health and the Environment (RIVM) and the Medicines Evaluation Board (MEB) have commissioned an eighteen-story glass tower to house their offices and laboratories. The design criteria set the highest possible standards for sustainable construction including the building materials, landscaping and HVAC systems.

Challenge

This substantial structure will provide 80,000 m2 of floor space including 17,000 m2 for laboratories. It will accommodate around 2,200 employees. The design has been certified “Outstanding” by the BREEAM-NL (Building Research Establishment Environmental Assessment Method). This represents the highest rating ever for such a complex and extensive project.

Builders MEET Strukton, under the direction of Felix Claus Dick Van Wageningen Architects, turned to Trane for a solution.

Solution

Trane recommended the revolutionary XStream RTWF heat pumps. This latest water-to-water heat pump range extends efficiencies to the extreme through a serial counterflow design of the two embedded refrigerant circuits.

Three RTWF G 240HE high efficiency heat pumps and one RTWF G 240HSE high seasonal efficiency heat pump are the heart of the system, further optimized by Trane’s Chiller Plant Manager making sure that the products always deliver the best possible system efficiency, all year round.

Geothermal storage boosts efficiency even further up to the record braking efficiency level.

Trane XStream RTWF uses R1234ze refrigerant, an HFO with zero ODP (Ozone Depletion Potential) and a less than 1 GWP (Global Warming Potential).

Construction started in 2017, completion is scheduled in 2021. The HVAC equipment will be installed in Q3 2019.

Result

Comfort, Efficiency, Sustainability

Four heat pumps were selected optimizing comfort of the work places and enabling greater energy efficiency of the building. Each Trane XStream RTWF include two refrigerant circuits and a total of three compressors. By adding the Trane Adaptive Frequency Drive (AFD) to the high-efficiency heat pump, part load performance is maximized at all working conditions.

Optimized operation, optimized economy

The exceptional efficiency of the Trane XStream cuts energy usage reducing total cost of ownership to the minimum. Maintenance costs are minimal thanks to Trane’s legendary screw compressor design ensuring life time to exceed industry standards by 200%: It’s Hard to Stop a Trane.


The Public-Private Partnership with a Design, Build, Finance, Maintain, Operate contract is ensuring that decisions are made in the long term interest of the customer. Beyond the construction itself, MEET Strukton is also responsible for twenty-five years of maintenance and operation.
