Chilleweni Cold Storage Solutions provides cold storage and refrigerated logistics services to several of South Africa’s largest brands within the frozen food market.  Their new, larger and more improved home in the Randport Industrial Park is strategically located adjacent to the Elands Interchange, a major transport node situated in the well-established industrial hub of Gosforth Park, Germiston. The Facility benefits from high visibility and accessibility in all directions.  The N3 links the site Northward to Pretoria, the M2 Geldenhys Interchange, Ekurhuleni and OR Tambo International; Southward to Alberton, Vereeniging, and Durban.  The M2 links the site Westward to Johannesburg City Centre and Roodepoort; Eastward to Germiston. A fresh design approach has given rise to a unique building which compliments the strategic and locational benefits of the building. The harmonious choice of structural elements combined with technology, technical aesthetics, colour and material has resulted in a visually appealing industrial building fit for purpose. It is a building which enhances the experience of the user and adds value to the immediate context.

Industrial buildings are characterised by standard ‘archetypal features’ such as large unbroken facades, blank walls, large spans of repetitive faces and materials which integrate various engineering structures and equipment.  Through careful artistic treatment, systematic arrangement and sensible proportioning of these main and pronounced features, the repetitive appearance of a ‘standard’ industrial building was avoided.  Instead, the harmonious choice of structural elements combined with technical aesthetics, colour and materials resulted in a visually appealing industrial building fit for purpose, one which enhances the experience of the user while adding value to its immediate context.

External materials such as sheeting and tilt-up reduce the cost of maintenance and increase the longevity of the building.

Utilisation of pumped ammonia to all Low-Temp and Medium-Temp areas to reduce capital cost and improve efficiencies.

Detailed financial evaluations done for Ammonia (NH3) vs Carbon Dioxide Plant (CO2). Ammonia found to have a 23months payback on additional capital and an electrical saving of ±R 2M per annum.

  • The development has been a success as it has had a positive impact on the local community, immediate surroundings and neighbouring precincts, while adding to social upliftment, transformation and job creation within the community.

Complexity of the services combined with aesthetics

  • Longest known freezer in SA, possibly Africa with single throw fans: 55.95m
  • Integral compressor oil cooling providing waste heat for underfloor glycol to prevent frost heave.
  • Bespoke in-rack blast freezers installed inside the main freezer chambers allowing for integrated blast freezing utilising primary room coils as opposed to dedicated blast freezer room.
  • Construction period of 8 months. Most facilities this size take 10 months to a year to complete.
  • Is this proposal clear and well presented? YES

The main contractor is a Level Four BEE Contributor comprising 51.57% black ownership with a 100% BEE procurement recognition level.  In addition, the main contractor employed the Gosforth Local Community Forum to undertake brickwork and paving installations.  Chilleweni has increased their operation capacity, and by so doing, have employed more staff.  The quality of the facility impacts its immediate surroundings and improves the amenity of the area.  It is a catalyst for encouraging more business to develop new and improved facilities in the area, contributing further to social upliftment.

Through well thought out spatial arrangements coupled with quality finishes and design, the user experience is positively enhanced. Low emissivity glazing and strategically positioned windows allow natural light to filter deep into the office space.  It connects the user to the amazing vistas surrounding the site. The office HVAC system is designed with reduced chilled glycol supply temperatures to optimise HVAC equipment efficiency and performance to create a comfortable climate at a reduced operational cost while reducing environmental impact. The staff/ back of house facilities share the same amenity and are not segregated from the main office portion.

The building is comprised of cellular offices, open plan offices, balconies, pause spaces, chillers, freezers, and mechanical plants. It boasts a unique Complexity of services combined with aesthetics, and sets a design precedent for buildings which combine complex engineering services with aesthetics rather than being an archetypal and standard industrial building. The building has uplifted staff morale and has encouraged passers-by to stop on the side of the road to have a closer look.

Locally sourced and primary materials such as sheeting, structural steel and aluminium used. Concrete use limited.  Steel speeds up construction period and is highly recyclable, meaning it can be capitalized on by future generations. It also limits the operational costs during construction.  Further reduction in operational costs achieved through careful selection of material colour, insulation and use of Low-emissivity glass.  Office HVAC system designed with reduced chilled glycol supply temperatures to optimise HVAC equipment capital cost and utilize highly efficient primary ammonia plant operating at a Coefficient of Performance of 4.93. Waste heat from compressor discharge used to mechanically dehumidify the receiving and despatch area. All condensate from blower coils harvested and re-utilized for heat rejection in condensers. Highly efficient, two-stage ammonia plant operating at a Low-Temperature Coefficient of Performance of 5.62 and a Medium-Temperature Coefficient of Performance of 4.93. Decreased TEWI (Total Equivalent Warming Impact) vs synthetic and other natural refrigerant options evaluated due to reduced primary and secondary emissions. All-natural refrigerant designed with zero Ozone Depletion Potential and Global Warming Potential. Integral compressor oil cooling providing waste heat for underfloor glycol to prevent frost heave.
