HBS New Energies completed the design and installation of a 109.89 kWp PV system as part of a major refurbishment of 4 Longwalk, Stockley Park. Integrating solar PV into the construction of this modernised office ensured the project achieved an ‘Excellent’ BREEAM rating.
In 2015, Kier started a complete refurbishment and extension of 4 Longwalk, a four-storey office HQ within Stockley Park. Working on behalf of main contractor Kier Group, HBS New Energies completed the design and installation of a roof mounted solar PV system that would ensure the building achieved its targeted EPC B and BREEAM “Excellent” ratings.
The project was completed in 2016, with the 100,000 sq ft building upgraded to modern standards, meeting a high level of sustainability with a CAT A standard fit-out. The office HQ which is owned by Aberdeen Asset Management was designed by architects, Barr Gazetas.
- HBS New Energies managed all stages of the projects solar PV requirements. This included design, supply and installation right through to testing, commissioning and connection. The contracted works included DNO approval and help with the ROO-FIT application.
- Following a detailed site survey, our in-house design and technical engineers designed a PV system that would best suit the roof type whilst meeting the client’s renewable requirements.
- We specified 330 x Ben Q 330W modules to ensure the PV system would meet the required performance and kWh output.
- Integrating solar PV into the construction of this office refurbishment proved to be most cost-effective solution to help the project achieve an ‘Excellent’ BREEAM rating and EPC B rating.
- The roof mounted 109.89 kWp solar PV system will generate up to 98,063 kWh of clean electricity each year, reducing the building’s energy consumption from the grid. In addition to the energy savings, the inclusion of solar panels will help to offset the office’s carbon footprint, delivering an estimated 51,777 kg of CO2 savings per year.
