What was the developers brief to you for the building?
We have done several buildings for Bidfood and their brief is all similar. The size of the warehouse & office is dictated by their location and city size, as this was in Nelspruit the size was not to big 3000m2 in warehouse space, including a freezer area and 1500m2 of office space, all to be covered by one warehouse roof. The roof design is affected by the internal access to the freezer pods which cool the freezer area, as well as allowing space for the smoke ventilators and translucent sheeting which allows more natural light into the warehouse.
Were there any particular innovations you were looking to achieve from the steel cladding?
As we have a freezer inside the warehouse, the freezer panels can be exposed to the elements thus not needing cladding around the freezer. This allows us to only clad to 1m under the top of the freezer, this is a unique design which separates our building from other warehouses. This is not really an innovation, but is different from any other warehouses we do.
Any specific other details you would like to mention that you feel would help the submission?
As we have a fairly large roof area, this allowed us to harvest rain water from eastern slope of the warehouse (approximately 2400m2 of roof) into a rainwater harvesting area. This water was then connected to the internal plumbing as grey water which was used to flush toilets, urinals and irrigation water.
The Western side of the roof (approximately 1300m2 of roof) was used for solar panels which were connected to our geysers and heat pumps to save on the electrical demand.
