HBS New Energies worked for NG Bailey on a large office refurbishment project at Stockley Park. We completed the design and installation of a 72.8 kWp solar PV system to The Bower building, helping the upgraded office achieve an ‘Excellent’ BREEAM rating.

In 2015, the Bower building at 4 Roundwood Avenue, Stockley Park underwent a £24 million pound office upgrade and extension. NG Bailey transformed the existing three-storey property into one of the largest and most highly specified office developments in the Thames Valley region. It now offers an impressive 151,074 square foot of world-class office accommodation.

HBS worked on behalf of contractor NG Bailey to deliver the development’s solar PV requirements. We made a significant contribution to the success of this project, helping The Bower meet the highest levels of sustainability and achieve the required ‘Excellent’ BREEAM rating.

Project delivery

  • The new energies division provided a full service solar PV solution. We managed the system design, supply, installation and commissioning. Contracted works included all necessary DNO approval and help with the ROO-FIT application.

  • Following initial surveys, our in-house design and technical engineers designed a solar PV system that would best suit the roof type, whilst meeting the projects renewable requirements.

  • We specified JA Solar 280W modules that would ensure the PV system would achieve the required performance and kWh output.
  • The roof mounted 72.8 kWp solar PV system will generate up to 65,156 kWh’s of clean electricity each year, reducing the building’s energy consumption from the grid. Furthermore, the system will help reduce the development’s overall carbon emissions, with annual CO2 savings estimated at 34,402 kg.
  • Integrating solar PV into the construction of this £24 million pound office renovation proved to be most cost-effective solution to help the project achieve an ‘Excellent’ BREEAM rating and EPC B rating.
