Project summary
The award-winning Eden Project has been one of Cornwall’s most popular tourist attractions since it opened in March 2001. The remit of the site is to promote the understanding and responsible management of the relationship between plants, people and resources to create a sustainable future for all. The design of the Education and Resource Centre ('The Core') is inspired by plant formations, created by world-leading architects Nicholas Grimshaw & Partners. The Core has taken two years to construct at a cost of £15 million. Major sponsors included the Millennium Commission Lottery, South West Regional Development Agency, and the European Regional Development Fund via Objective One. The Core demonstrates the use of solar energy in combination with complicated architecture and how standard PV panels can be incorporated within complex structures to deliver a highly aesthetic, practical solution. Despite the challenge of The Core’s intricate design, the PV was fully installed within the project's build programme.

Special PV project info
PV architecture and building integrationIn order to meet the architect’s desire for the ‘Fibonacci’ roof curves, solar panels were intricately faceted over a bespoke mounting structure constructed from a spiral of steel tubes. This design was met using a combination of 338 Sharp 80W panels and 42 Kyocera 40W panels; each ‘petal’ of the flower formation on the roof was constructed using standard PV panels. The intricate shape of each ‘petal’ was achieved through descending row lengths of PV panels, extending from the centre. At the eave of the roof over the solar terrace, bespoke Romag 80W glass-glass laminates form a ring that completes the centre of the flower. These panels are mounted using bolt-through glass fittings and provide a canopy to protect the building’s timber exterior finishes with the added benefit of offsetting building material costs.
