How would you rate this course?
1: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
An increase in energy efficiency of 35%
1: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
No real energy savings – but 35% installation cost savings

1: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
The savings depend on water pricing
You can find the answer here >
2: Is material waste reduced when using Grundfos Modular HVAC systems?
No, the benefits come from less need for time consuming transportation and assembly onsite
You can find the answer here >
2: Is material waste reduced when using Grundfos Modular HVAC systems?
Yes, as factory production of HVAC modules is far more efficient than onsite construction
2: Is material waste reduced when using Grundfos Modular HVAC systems?
No, you get the security of one supplier – but you still need to unpack and install onsite

3: Do building services perform as expected in a typical commercial building project?
No, only 2% of new buildings have a performance that matches the design estimate
3: Do building services perform as expected in a typical commercial building project?
Yes, only 2% of buildings do not perform as they were designed to

3: Do building services perform as expected in a typical commercial building project?
No, but this is expected – adjusting and optimising building services after completion is always calculated into costs

4: Why is installing a Grundfos MIXIT mixing loop solution a good idea?
It can be for some buildings – if price but not efficiency is important
You can find the answer here >
4: Why is installing a Grundfos MIXIT mixing loop solution a good idea?
You get the security of one supplier – but you still need to ensure capability between system components in your installation

4: Why is installing a Grundfos MIXIT mixing loop solution a good idea?
You reduce complexity and time spent on selecting and sizing and MIXIT is up to 25% more cost effective than other solutions
5: What component does a Grundfos distributed pumping solution make redundant?
Primary pumps

5: What component does a Grundfos distributed pumping solution make redundant?
Balancing and control valves
6: Can Grundfos products be monitored and controlled via a BMS system?
No, Grundfos pumps provide load adaptive performance, so no external control is possible
