What was our client looking for?

A major refurbishment of the headquarters of the Ocean Housing Group
in St Austell means that the building now showcases a state-of-the-art
photovoltaic installation. The initial phase of the project, completed in
October 2010, involved replacing the old asbestos roof with over 1200m2
of Kingspan KS1000 RW insulated panels.

How did we help?

MITIE was the main contractor on the project, assessing the structural
capability of the existing building, optimising the system design and
successfully project managing the complete installation of the PV
system. In total 273 Sharp 210W polycrystalline PV modules with a
57.33kW peak capacity were installed to the south facing elevations of
the roof.

Matthew Goddard, Commercial Manager MITIE Tilley Roofing said, “The
programme went really well and the project was delivered on time.”

“We are in a win-win situation,” explained David Renwick, Chief
Executive of the Ocean Group. “All the ‘green’ electricity we generate
on site is free for us to use. On top of this we are rewarded for every
kilowatt hour of energy we produce, with an additional bonus for the
electricity we sell on.”

“The figures really stack up, especially as all the electricity we produce

when our offices are closed during the weekend and summer evenings,

is sold back to the grid, making us more money,” continued David. “And

what makes this project really exciting, is that we can now assess the

technology for future use in a significant proportion of our homes, with

the aim of making fuel poverty a thing of the past for our residents.”

The results

Actual kWhs produced were 9.95% higher than predicted.

CO2 reduction was 12.14% better than anticipated.

It is estimated that the electricity produced from the 57.33KW system will

save the Ocean Housing Group more than £20,000 annually.
