  • Successful collaboration for world-famous Eden Project

  • An editor visit to the Eden Project has resulted in major press coverage for Priva in Building Services and Environmental Engineer (BSEE) magazine. The coverage celebrates a highly-successful collaboration between Priva and its partner company, CambridgeHOK, who worked together to help the Eden Project to initially cut its carbon footprint by 111 tonnes of CO2.

    10th anniversary
    Cornwall's world-famous Eden Project, which celebrated its 10th anniversary last year, is a rich, global garden that allows its visitors - more than 10 million since it first opened - to learn about nature. However, maintaining the delicate climate insideEden's huge, domed 'biomes' requires an enormous heating load that originally created a carbon footprint at odds with its green ethos.

    Building Management System
    Eden recognised that it needed to control its indoor climates more efficiently by updating its Building Management System (BMS). However, the integration between horticultural and building control systems on a huge scale posed a considerable headache. Under the old BMS,Eden had no less than 49 separate control system operating across site. Worse still, many of its controllers were no longer supported by their manufacturer.

    Priva Building Intelligence
    Eden needed a single system that could control every part of the site. With this in mind, in 2010, building controls specialist Cambridge HOK began installation of a new, state-of-the-art BMS from Priva Building Intelligence. Priva technology was chosen for the project because its controllers are wholly future-proofed - meaning that the system will not become obsolete a few years down the line. The system is flexible enough to evolve as the Eden Project evolves.

    Energy savings
    In the period since the completion of the first phase in September 2010 to May 2011 Eden has recorded energy savings of 10% in its Energy Centre and 19% in its Visitor Centre. This amounts to a combined financial saving of £16,515, plus a reduction of 111 tonnes of carbon dioxide. Work is ongoing at Eden to further improve energy-efficiency on-site, but the bulk of the current savings is down to the more effective control strategies of the Priva system.

  • Improving energy effiency
    David Moore, Maintenance Manager for the Eden Project, comments: "Improving energy efficiency and overhauling the building controls at the Eden Project was always going to be a complicated and daunting task. Although several BMS manufacturers were able to supply a system to us, Priva Building Intelligence was the only one with the depth of understanding to make the project into a reality. The result has been a site that not only uses dramatically less energy, but is also streamlined, allowing for better communication between all parts of the Eden Project."

    Future-proof
    Anders Norén, Managing Director of Priva, comments: "Priva comes from a background of managing energy in horticulture, and we were pleased to be able to combine this knowledge with our building controls expertise, in order to lower carbon emissions and improve efficiency at the Eden Project. It is a huge accomplishment all round, ensuring that the horticultural and building control technology work in harmony to maintain a site that is highly-efficient and future-proof."
