The Key Theatre in Peterborough’s city centre combined Bauder’s reinforced bitumen membrane waterproofing system and sedum blanket green roof finish with a photovoltaic solution. The PV array maximised the assigned roof area with 290wp modules inclined at a 10° angle for optimum energy generation per square metre and reduced wind load impact. The PV panels deliver 15.7% efficiency for a powerful and reliable solution.

Products applied

BauderSOLAR:

An innovative photovoltaic system that does not require any drilling of the deck or ballast to install the substructures and modules.

The result

The green roof system comprised a warm roof construction with an efficient PIR insulation, 27 PV modules were installed with an expected energy generation of 6.5 MWh. The project delivered entirely to the client’s aspiration - a comprehensive sustainable solution to maximise the environmental benefits of the roof.

Advocacy 

Mike Phillips, council's contract manager:

"Bauder was already the supplier for the building’s waterproofing membrane, it made sense to source its PV system. We were going to get a Bauder warranty at the end of the roofing works and we didn’t want to compromise that by using a frame PV system and drilling through the waterproofing.”
