A series of upgrades will help the Eden Project cut its CO2 emissions by 25 per cent over the next two years.
The upgrades, to the project’s technical systems, could be replicated in homes.
It builds on work by Eden to cut its energy usage over the last three years. It has cut its electricity consumption by 6.5 per cent and gas intensity by 20 per cent in this period.
A new Building Management System will be installed which will integrate the temperature controls in the Biomes with related systems on the rest of the Eden site.
The new system provides tight control of heat and electricity consumption and will combine with further upgrades to Eden’s heating system.
These changes are estimated to greatly increase efficiency and, as a result, reduce Eden’s footprint by 694 tonnes of CO2 per year.
A new gas-fired, high-efficiency boiler system has been installed at Eden’s Watering Lane Nursery near Pentewan to reduce CO2 emissions by an estimated 231 tonnes per year. This will replace the previous oil-fired system.
Approximately 746 new LED lights have also be installed across the Eden Project, saving in the region of 51 tonnes of CO2 a year. This is one of the biggest installations of its kind in the country. The lights were installed and assembled in part by Softsun, a company based in nearby Bodmin.
Eden’s energy manager, Matt Hastings, said: “While renewables are very important, the most critical tool in the box is a focused commitment to reducing consumption.”
