Refurbishment Project of the Year (value over £5m)
HVAC Roof Infrastructure, Harrods, London - Harrods
London's iconic Harrods store grabs the gong for a complex 10-year refurbishment programme that has delivered improved internal conditions, energy reductions and more resilient building services.
Harrods' rooftop HVAC project is a scheme that was conceived more than 10 years ago. It was developed to replace existing, ageing infrastructure while at the same time introducing extra capacity to support future expansion plans. The ethos was to strive towards reducing energy consumption, improve comfort levels within the store, and to enhance the resilience of the system.
During the work, retail space grew from 925,227 ft2 to 1,381,691 ft2 while the building's annual electricity consumption has fallen from 49,000 MWh to 41,500 MWh per annum during the same period. The cumulative effect is a reduction of more than 4,000 tonnes of CO2 each year.
The scheme has demonstrated strong collaborative working between the project team in the delivery of a complex refurbishment spread over a 10-year period. The ability to establish a strong design brief early in the process, maintain the principles through design and construction phases, and to deliver the project with no dilution of the original vision, is very rare.
The scheme was completed without affecting the store's operation, despite the complete replacement of all air handling plant and chillers during the some of the coldest, wettest and warmest periods experienced in recent times.
The difficulties of working within a Grade II listed building, which is also an icon for London and tourists, was not used at any time as an excuse to avoid striving for the best technical solutions.
While this created the hardest challenge, the team's determination to work with the existing building has paid big dividends in the overall success of the project, which can be measured in real terms with reduced energy consumption and improved internal environment.
