Portsmouth HQ achieves BREEAM Excellent rating

A Portsmouth building has been awarded a BREEAM Excellent certificate, achieving the second highest rating for sustainability.

Named after the Land Rover Ben Ainslie America’s sailing team, the 74,000 ft² Land Rover BAR in Camber Dock was designed by HGP Architects and built by Allied Developments.

Part funded by a £6.5m government grant, the building saw sustainability embedded from the outset with 98 per cent of all demolition, excavation and construction waste diverted from landfill and 100 per cent of the demolition concrete reused in the foundations as secondary materials.

BIM technology enabled the design team to undertake life cycle analysis of the design choices while providing informed options for in-use performance monitoring. A bespoke building management system monitors 15 different points including energy and water consumption as well as renewable energy generation and waste.

More than 400 solar panels cover the available roof space while natural ventilation is achieved through the central atrium. Rainwater harvesting has led to a 25 per cent improvement in water efficiency over existing UK building regulation standards. In addition, the building’s fabric wrap provides a heat-saving air cushion of approximately 5°C and controls the amount of sunlight that enters the building, reducing energy used for cooling and carbon emissions.

Matthew Williams, Director, HGP Architects commented:

“Using modern methods of construction – and with technologies incorporated into the design to seek carbon neutral credentials – Ben Ainslie and his team have sought to commission a team home of cascading layers linked together through a central light well that connects everyone to the heart of the team and the boat.”
