Shopping Centres

Supermarkets and other mechanically cooled buildings can directly measure the benefits of SkyCool through energy savings. However, non-air conditioned shopping complexes, warehouses and factories can have equally important need for keeping their environment cool and comfortable.

Mirvac Group - St Mary's Village - Sydney,   N.S.W.

Mirvac's 17,000 square metre St Mary's Shopping Centre invested in SkyCool to help reduce the cooling demand for the air conditioning plant. Results were so effective (at one time retaining overnight frost on the upper roof till late morning) Their investment was so worthwhile that they have continued to deploy SkyCool on more of their retail properties in NSW as well as Queensland.

Here is what Mirvac's Facilities Manager actually said.

Direct Factory Outlets - Moorabbin, VIC

Direct Factory Outlet centre at Moorabbin, Victoria was looking for a solution to cooling the inside environment for customer comfort. While the most recently constructed sections of the building contain air conditioning, the original 13,000 square metres laboured under a non-insulated roof, with a small number of evaporative cooling towers. This large area of the building was experiencing difficulties with over heating during the warmer months.
 
It was recognised by the centre’s consulting engineers that the majority of the heat was entering through the roof from the solar load. A normal galvanised metal roof will often attain temperatures approximately twice that of the ambient shade temperature – on a 30°C day, the roof can be as much as 60°C transforming it into a large overhead radiator.
 
As part of their pre-application research into SkyCool, the Queensland University of Technology was asked to model the effect of SkyCool on their building. The graph below was produced by the University takes into account Melbourne weather variations hour-by-hour throughout the year. It shows the effect of SkyCool on the temperature of the air immediately below the uninsulated roof. At the peak of summer, SkyCool has the ability of bringing an overall sub-roof temperature of 65°C down to about 25°C. The occupied level of the building would experience a resultant temperature move from the mid to high thirties to the mid twenties.

Charter Hall - Sth Headland, W.A.

South Hedland is located only about 100 km from Marble Bar which is famous for being one of the hottest places on earth. In the very hot summer of 2008-09 one of the two air conditioning chillers in the shopping mall had collapsed leaving the remaining chiller to pick up the load as well as supply the K-Mart store. Needless to say it was significantly over-taxed.


SkyCool was applied to the common and small tenancy roof areas in early January 2009 where uncoated roof temperatures were reaching 87c - even melting the soles of the shoes worn by the applicators. Comparing that temperature of the uncoated roof section on 9 Jan 2009 at 11am with the coated roof, the difference was amazing. Uncoated roof = 87c whereas the coated roof still retained overnight dew.


 The difference was so powerful that the centre did not have to replace any air conditioning plant until the second chiller finally wore out some 9 months later.
