London’s Natural History Museum has agreed a new 10-year energy performance contract (EPC) with Veolia after energy efficiency measures under the previous contract had “over-achieved”.

As part of the museum’s Carbon Reduction Masterplan, Veolia’s subsidiary Veolia-Cynergin implemented trigeneration combined heat and power (CHP) solutions for two museum sites as well as boiler replacement and an air conditioning plant.

The company says the measures have exceeded the guaranteed annual net savings of £54,000 ($70,000) every year after investment payback and have reduced the museum’s carbon emissions by 1500 tonnes per year.

Richard Kirkman, Chief Technology & Innovation Officer with Veolia UK and Ireland, said: “By implementing the latest energy efficiency measures the Natural History Museum have been able to save on energy costs which have funded these major enhancements.

“In this way Energy Performance Contracts make good economic and environmental sense for those looking to reduce carbon emissions, boost sustainability and minimize capital outlay.”

Veolia acquired Cynergin in January.
