GREEN building company CA Group Limited has upgraded its own headquarters to create one of the most energy efficient factories in the North-East.

The building, which features a combination of solar technologies and CA Group’s own Twin-Therm® roof and wall system, is expected to save as much as 55 peer cent on the combined heating and electricity requirements, when compared with its base build performance, the company claimed.

The company based at Evenwood, near Bishop Auckland, which specialises in the manufacture and installation of some of the UK’s largest warehouses, has fitted 849 solar panels to the roof of its profiling mill.

It is estimated that the panels will have paid for themselves in six years and will see CA Group generating on-site electricity well beyond 2040.

Andrew Brewster, project development manager for the County CA Group, said: “As one of the largest employers in the area, we are acutely aware of our potential to impact on the local environment and community and we want to ensure this is kept to a minimum. Investing in the next generation of green electricity and reducing our operational energy consumption, and the resulting CO2 emissions, is just one example of our commitment to doing so.”
