BRE Offices



The Task

Alternergy, in partnership with South Facing, supplied the roof mounted PV installation at the large research office complex for the Building Research Establishment (BRE) in Garston. The new system was installed to help reduce the BRE’s carbon footprint. BRE’s S Plan sets out a four-year programme of continuous improvement across eight key areas of sustainability: carbon dioxide emissions; resource efficiency; supply chain engagement; transport; community engagement; ecology; water; and information systems.

Why Choose Alternergy?

For the BRE, it was critically important that the products and companies met their very high and exacting standards. Alternergy was chosen due to their ability to manage the complex logistics involved in an installation of this size. Overall, the products needed to meet the requirements of high quality, superior energy generation, from trusted brands with strong warranties backed up by manufacturers that are viewed as being financially strong and stable.

Rajiv Bhatia, Director of Alternergy said, “We were proud to be selected as the supplier of choice for such a prestigious installation. With such exacting requirements on quality and delivery, Alternergy was one of very few companies that had the ability to deliver.”
