How would you rate this course?
1: 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
1: 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

1: 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

2: A distributed pumping system is self-balancing – what does this mean?
No need to integrate a primary pump into the building’s management system
You can find the answer here >
2: A distributed pumping system is self-balancing – what does this mean?
No time-consuming balancing and commissioning process is required
2: A distributed pumping system is self-balancing – what does this mean?
No need to manually check return and control valves – they adjust automatically

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: 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%
5: 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
