Project overview

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.

The project delivered entirely to the client’s aspiration - a comprehensive sustainable solution to maximise the environmental benefits of the roof.

Applied Products

  • The BauderSOLAR SOLfixx photovoltaic system is an innovative solution that does not require any drilling of the deck or ballast to install the substructures and modules.
  • 27 PV modules were installed with an expected energy generation of 6.5 MWh.
  • The green roof system comprised a warm roof construction with a highly efficient PIR insulation. The root resistant cap sheet is a 5mm thick SBS modified elastomeric membrane.

Mike Phillips, council's contract manager: “Because 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.”
