Grundfos Distributed Pumping makes it easy to balance chilled water systems and enhancing comfort in buildings. The solution replaces traditional balance and control valves with intelligent pumps. This improves Delta T and reduces pump energy in commercial buildings.

Saving operation costs with distributed pumping at Ngee Ann Polytechnic, Singapore

The occupants' comfort is high on our priority list and so is maintaining our Green Mark Platinum rating. Grundfos' Distributed Pumping helps us achieve both.
Facility Manager, Ngee Ann Polytechnic Block 22

Located in Singapore, Block 22 at Ngee Ann Polytechnic (NP) is a mixed-use building housing a cafeteria, sports hall, student lounges and office spaces. The building was finished in 2014 and runs on a third-party BMS with a constant load profile. Its total cooling area is approximately 6000 m². The Singapore Building Construction Authority has certified Block 22 as a Green Mark Platinum building.

HVAC is responsible for about 60% of the buildings total energy consumption. To uphold its Green Mark Platinum rating and achieve even higher energy savings, management and the Environmental & Water Technology Centre of Innovation (EWTCOI) decided to revisit its HVAC system design, which is based on a chilled water loop. The goal was to identify ways to push energy savings while maintaining a cool, comfortable environment throughout the building.
