Is material waste reduced when using Grundfos Modular HVAC systems?
Do building services perform as expected in a typical commercial building project?
In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
A distributed pumping system is self-balancing – what does this mean?
Why is limited space for HVAC installations an issue for building projects?
Does choosing a hydronic system affect the indoor climate?
Test results
Congratulations. You have passed the test and completed the 84 - Adding value in HVAC applications
Achieved badges:
Q: Is material waste reduced when using Grundfos Modular HVAC systems?
A: No, the benefits come from less need for time consuming transportation and assembly onsite
Q: Is material waste reduced when using Grundfos Modular HVAC systems?
A: Yes, as factory production of HVAC modules is far more efficient than onsite construction
Q: Is material waste reduced when using Grundfos Modular HVAC systems?
A: No, you get the security of one supplier – but you still need to unpack and install onsite
Q: Do building services perform as expected in a typical commercial building project?
A: No, only 2% of new buildings have a performance that matches the design estimate
Q: Do building services perform as expected in a typical commercial building project?
A: Yes, only 2% of buildings do not perform as they were designed to
Q: Do building services perform as expected in a typical commercial building project?
A: No, but this is expected – adjusting and optimising building services after completion is always calculated into costs
Q: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
A: An increase in energy efficiency of 35%
Q: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
A: No real energy savings – but 35% installation cost savings
Q: In our example, how much more energy efficient is a hydronic system compared to an air-based VAV system?
A: The savings depend on water pricing
Q: A distributed pumping system is self-balancing – what does this mean?
A: No need to integrate a primary pump into the building’s management system
Q: A distributed pumping system is self-balancing – what does this mean?
A: No time-consuming balancing and commissioning process is required
Q: A distributed pumping system is self-balancing – what does this mean?
A: No need to manually check return and control valves – they adjust automatically
Q: Why is limited space for HVAC installations an issue for building projects?
A: If too little space is used, you have high operation and service costs; and using too much space reduces the floor area that can be rented out
Q: Why is limited space for HVAC installations an issue for building projects?
A: If the required amount of space is planned for at the design stage, this will not be a problem – as long as it matches the size of the installation
Q: Why is limited space for HVAC installations an issue for building projects?
A: This is an issue that can be resolved by renting out the installation floor area to the service provider
Q: Does choosing a hydronic system affect the indoor climate?
A: No, you choose a hydronic system to save money on installation and energy
Q: Does choosing a hydronic system affect the indoor climate?
A: Yes, indoor climate is improved, and you get cost savings as well
Q: Does choosing a hydronic system affect the indoor climate?
A: Yes, the improved indoor climate makes it worthwhile paying for an expensive solution
