Breezair's evaporative cooling system from distributor CoSaf Environments has been specified for two major building projects in the higher educational sector for being the most environmentally suitable and cost-effective means of cooling the buildings
Institutions are increasingly concerned with their environmental impact, and new building programmes provide an obvious opportunity for adopting best environmental practice and using the latest technology to create greener buildings.
Breezair Icon coolers have been specified by WS Atkins for the new £9m Marine & Built Environment Centre at Llandrillo College in Colwyn Bay, North Wales. Due to open in November, the Centre will include a range of full and part-time courses associated with the marine sector.
For this Building Research Establishment Environmental Assessment Method (BREEAM) education building — the Government’s benchmark to measure the environmental performance of buildings — four Breezair Icon coolers have been specified to provide cooling to the second floor classrooms and IT rooms. The coolers are installed externally with conditioned-air being ducted to each classroom.
In order to maintain the optimum temperature and maximise free cooling, the units automatically adjust the motor speed to cope with different ducting systems and back pressures. The coolers are being operated by a Building Management System which is also linked into a rainwater harvesting system to maximise use of the reclaimable rainwater and enhance the system's ‘green’ credentials.
Cooling a flagship campus
A total of 20 Breezair units have also been specified by the international consultancy OPERON Group for the new £100m flagship campus for Stockport College. When completed, the campus will provide 10,000 students with an exciting learning environment with state-of-the-art teaching facilities, shops, restaurants, salons, workshops and sports facilities.
Here, the Breezair coolers will provide summer and winter ventilation together with full summer comfort cooling to all four floors of the new structure. Breezair Icons are located at roof level with conditioned-air being ducted to each room via DW144 galvanised ducting automatically vary the air volume to maintain space temperature and maximise free cooling. As with Llandrillo College, the cooling system the coolers are being operated with a BMS in order to maintain year-round ventilation.
These quiet, efficient coolers hold VDI 6022 air hygiene certification and are said to consume up to 40 per cent less power than conventional ducted evaporative air conditioning systems and up to 90 per cent less than refrigerated units. Cost-effective to install and run, the emission-free units provides excellent cooling properties and ventilation with minimal energy consumption.
They allow a constant flow of 100 per cent cooled, natural fresh air to be drawn into the building and then expelled. The majority of all odours, germs and airborne contaminants are removed from the incoming air and expelled without being re-circulated.
