Waterloo helps deliver 80% energy savings at Scottish retail centre
As part of a major refurbishment programme for one of Aberdeen’s major shopping destinations, Waterloo Air Products plc has supplied a wide range of air diffusers including customised designs for the eating areas and helped contribute towards an overall 80% reduction in energy.
Air terminal devices have been used throughout the Bon Accord shopping centre where there was a need to design an efficient air distribution system to help reduce emissions and carbon footprints.
The centre, whose landlord is Scottish Retail Property Limited Partnership, is a joint venture between Land Securities and British Land with over 200 stores.
A £6million make-over has now been completed and was carried out in two phases, which included new entrances and a stunning new interior providing shoppers with a fresh design, an atrium with sleek LED lighting, ceiling and flooring, renovated toilets and a range of stylish furniture, which achieves a modern contemporary look.
The centre was first built in the 1990s and much of the refurbishment work was carried out at night with minimal disruption to shoppers and retailers and the final phase of the multi-million pound development welcomed a new eating area to the centre with new names to the North-east including Pret-A-Manger®, Café Rouge & Di Maggio’s.
Land Securities was keen to reduce the environmental impact of its property portfolio on the environment, prior to carrying out any work the company analysed meter readings, motor run times and power consumption to enable it to identify energy saving opportunities.
This helped shape the refurbishment programme’s aim of carbon emissions reduction and energy savings which included improving the heating, ventilation and air conditioning facilities by installing heat pumps, investing in a CHP (combined heat and power) system and modifying the air handling system to optimise payback and lifespan of major plant.
By carrying out these changes Land Securities has achieved an impressive £50,000 of annual energy costs savings and an 80% reduction in the energy used for HVAC in the common parts, saving 330,560kWh and 139 tonnes of CO² emissions.
Air distribution was a key element with Waterloo being required to provide the most effective air distribution to maximise airflows and ensure that the air throws deliver the correct temperatures throughout the centre.
Waterloo’s ‘CSF’ range of linear slot diffusers have been used throughout the centre including the food court, atrium and Upper Mall .The modern architectural design of the food court required a customised solution, with Waterloo manufacturing bespoke products to provide long sweeping curved designs above the food court. These were finished in RAL 9003 with a 20% gloss level and are not only striking in their own right but provide high aerodynamic and acoustic performance with strong Coanda effects for good flow performance and hidden flow control vanes for consistent facial appearance.
Linear slot diffusers can be selected or set to provide horizontal diffusion in one or two directions across a flat ceiling surface and are suitable for a wide range of commercial applications.
Waterloo’s ‘MC’ small format circular diffusers were used in the second phase of the refurbishment which included the corridors and the North Mall. The MC diffuser is specifically for use in applications requiring compact circular diffusers. Unlike other similar designs on the market the MC has a small overall neck size ratio which is adjustable to produce horizontal or vertical air patterns.
High flow jet diffusers have been used in the toilet areas as their novel ‘reversible and rotational’ design allows air jets to be adjusted for both pattern and deflection. The diffusers are constructed from aluminium spinnings and feature long throw characteristics and high air handling capacity. They are easy to install and adjust.
