A lot of the work Sirus has done on the TCD campus involves identifying water chillers that have reached the end of their life cycle, and replacing them with more efficient models, a change, Stuart reveals, that saves TCD a great deal of money.
“The replacement of about one megawatt cooling here has accrued to approximately €12,000 a month in pure cost reduction.”
Monetary gain is not the only benefit to TCD of these replacements that Sirus recommends, Stuart says:
“The units that we recommend, they all use non-ozone depleting gasses, they have a smaller footprint, they have smaller proponents and they are lighter in mass which means the manufacturing process is less impact. The transport of those machines has less impact. The installation is easier.
“We also connect those using IOT technology both to the BMS on site and remote access. We can also enable remote access to the manufacturer at the factory as well to enable firstly, a quicker response and fix and secondly, we haven’t got the impact of having to bring engineers to site or to that location specifically until we know there’s a problem that requires their attention.”
The biggest barrier to actually putting into practice these energy efficiency policies is the gathering of existing data on a company's efficiency, according to Stuart.
“Certainly, when we’re working and talking to other potential or existing customers the hardest thing for us is getting the baseline data and actually gathering that data to enable the correct target of spend for the maximum impact in cost efficiency and carbon reduction,” he said.
