We were recently contacted by one of our US distributors, who claimed that a significant cost reduction had been achieved within just four weeks. BEST decided to send their Sales Director Ben Willcocks and Media Manager Steve Hill over to evaluate the results.
When the original water chilling equipment was installed, the system was set to perform an automatic system shut down when the chiller reached a certain minimum load. The campus engineer was unaware of this setting.
The Eniscope revealed that when the call for cold air across the campus was minimal, usually in the late night and the early hours of the morning, the system was actually shutting itself down and then restarting a few hours later. This caused a massive energy spike at each start up and undue wear and tear on the 30 and 50 hp pumps being used to move the cold water from one building to the next.
Our Distributor brought this information to the attention of campus engineers. In turn they were then able to work with the chiller equipment service company to tweak the equipment settings and avoid the late night shut downs and subsequent full system start ups. This generated savings of over 30% per month in that building alone.
This example clearly illustrates that you can not place a value on energy data until it has been acquired and evaluated. In this case, the energy data was instrumental in identifying a real problem which was ultimately a very simple “no cost” adjustment to correct.
Jesper and the team installed Eniscope at four locations considered ‘typical’ of the full portfolio.
In terms of raw figures, the full rollout equates (so far) to some incredible savings.
