The original building, known as the Speke Aerodrome, was constructed as the airport terminal in the 1930s, however this was replaced with a more modern building on a different location in 1986, and the Speke site was left derelict for over a decade. It has since been renovated and adapted to become a hotel, opening for business in 2001.

ENER-G had originally installed a CHP unit on site during the initial renovations in 2000 and Kew Green Hotels contacted us in 2010 to review and replace the existing system.

ENER-G had to ensure that the CHP system specified would be of optimal size to meet the demands of the site. This was critical as the system was also required to provide power for ventilation, lighting and other services.

After carefully assessing the site and carrying out detailed design work, ENER-G provided Kew Green with a proposal that included the supply and commissioning of a 110kWe CHP unit that also considered the requirements of the historic site.

The unit was installed in a roof top plant room, however owing to the site being listed with English Heritage, extra care had to be taken as the original Art Deco building could not be altered. In order to gain access to the plant room, the exterior wall had to be taken down brick by brick with photographic evidence documenting the process. A crane was then required to lift the unit carefully into place before painstakingly replacing each brick to its original position.
