Unison Headquarters, London

Client : Foreman Roberts, Building Services Consultants

The Project : £73m headquarters development covering an area of 4,800m2. Listed as one of the best buildings in London in 2011.

ERS Consultants Involvement:

ERS worked in collaboration with Foreman & Roberts, the M&E design consultant, to conduct a full Environmental and BREEAM assessment. With our support, the final scheme reaches over 50% carbon reductions above Part L of the building regulations. A biomass boiler and solar photovoltaics produce over 20% of the building’s energy. ERS more than met the objective, gaining an ‘as-built’ BREEAM excellent certification with a score of 73.53%, making it one of the most energy-efficient buildings in London.
