Solution

Q1 included a period when unusually hot weather should have resulted in increased cooling costs, however the site benefitted from an electricity saving of 30 MWh’s, as well as having a significant impact on base load gas consumption. Q2,3 and 4 continued to exceed the guaranteed minimum savings for both gas and electricity consumption. Climate complaints from occupants have also significantly decreased. All has been achieved through Ecopilot automatically, pro-actively and dynamically optimising the HVAC in real time, in accordance with the needs of the building and its users, whilst assisting the Parexel facilities team and their M&E and BMS contractors to improve the HVAC operation on site.

Results

As part of the verification process, Parexel used independently sourced data to validate the results presented to them. These confirmed the expected savings Ecopilot promised to deliver had been exceeded. Ecopilot’s initial assessment guaranteed an ROI of 2 years or less. The results confirmed that the payback on Parexel’s investment was only 9 months!
