Shopping centre shops with Waterloo
As part of a major refurbishment for a major shopping destination in Aberdeen, Waterloo Air Products has supplied a wide range of air diffusers, including customised designs for eating areas. They are helping to contribute towards an overall 80% reduction in energy consumption.
The £6 million make-over of the Bon Accord Centre, a joint venture between Land Securities and British Land, includes new entrances and a new interior. There is also an atrium with LED lighting and renovated toilets. The centre was built in the 1990s, and much of the refurbishment work was carried out at night.
Before work began, Land Securities analysed meter readings, motor-run times and power-consumption to help identify energy-savings opportunities.
As a result, improvements were made to the heating, ventilation and air-conditioning systems by installing heat pumps, a CHP system and modifying the air-handling system to optimise payback and lifespan of major plant. Energy costs have been reduced by £50 000 a year, with an 80% reduction in energy used for HVAC in the common parts — representing over 330 MWh and 139 t of CO2 emissions.
Air distribution was a key element, with Waterloo required to achieve effective air distribution to maximise airflows and ensure that the air throws deliver the correct temperatures throughout the centre.
CSF linear slot diffusers are used throughout the centre, including the food court, atrium and upper mall.
The modern architectural design of the food court required a customised solution, so Waterloo made bespoke products to provide long sweeping curved designs above the area. They are finished in RAL 9003 signal white with 20% gloss level. They provide strong Coanda effect for good flow performance and have hidden flow-control vanes for consistent facial appearance.
MC small-format circular diffusers were used in the second phase, which includes the corridors and the north mall.
High-flow jet diffusers are used in toilet areas, as their reversible and rotational design enables air jets to be adjusted for pattern and deflection.
Consulting engineers Wallace Whittle provided design services from its local Aberdeen office.
