Botswana Innovation Hub - New Data Centre And Office For Orange Botswana - AOS Consulting Engineers

On the 30th November 2018, Orange celebrated the 20th Anniversary of their operations in Botswana. For this important milestone, Orange had a ground breaking ceremony for their new data centre at the BIH Precinct in Gaborone. Present at the ground-breaking ceremony was the Deputy President of Botswana and other important dignitaries. Going through memory lane, we present the journey of the construction of the new data centre for Orange.


The Construction Process

For a successful development, Orange from the onset confirmed the budget and timelines and the technical team and the contractor were appointed based on their expertise and technical abilities. On the commencement of the project, governance structures were established jointly by Orange and the professional team to ensure adequate monitoring of the project for smooth and efficient delivery. The various photos below show the project progression and deliverables.



Site handover Date: 21st November 2018

Completion date & opening: 21st November 2019



Orange Botswana made it clear at the outset of the project the following constraints:

  1. Budget
  2. Time
  3. Quality
The project was completed within the budget, time and exceeded the quality standards.


An innovative design taking the following into consideration:

  • The new work out-performed current statutory requirements for sustainability through,
  • Maximizing energy efficiency


As the first purposed built data centre by Orange in Botswana, the project had become a reference point for success within the Orange Group globally. The team had established a framework for development.

State-of-the-Art Ammonia Cooling Service for South African Frozen Food Producer: Case Study

The need: Dr Oetker in South Africa, a producer and importer of frozen foods, wanted to increase their production and storage capacity since their existing facility was running out of space.

The solution: Energy Partners Refrigeration (EPR) installed a new three-stage ammonia refrigeration plant to supply cooling to the process areas, process fluids, blast freezers, holding freezers and cold rooms at the new production facility in Johannesburg (South Africa).

Reclaimed heat from the plant has been included in the solution to generate hot water for the site. With the selection of the Cooling as a Service (CaaS) model, the plant could be optimised for operational efficiency and redundancy while achieving the lowest possible carbon footprint.

The Changing Landscape of Refrigeration

As South Africa joins one hundred and twenty-eight other countries in implementing the Kigali Amendment to the Montreal Protocol 1 , the landscape of refrigeration continues to change.

In South Africa, the ‘baseline’ Hydrofluorocarbon (HFC) consumption is currently being determined so that, as early as 2024, this consumption will be ‘frozen’ and incrementally reduced to 20% of that baseline value by 2045 2. Read the entire article here.



Shoreline Sibaya, a retirement village, primed for healthy estate living is nearing completion after two long years of hard work and dedication by the professional team and client. It consists of:

  • 213 apartments broken into three separate blocks.
  • A central and easily accessible community centre.
  • The Care Centre providing residents with tailor-made, reliable day-to-day living with personal assistance.

Using the outdoor gardens and walking trails, retirees are given a sense of community, purpose, and connection with others. The ‘Village Green’ will act as a communal space where residents can get together for social engagement, and gentle activities, like walking, Tai Chi, or yoga.

HFW was involved from the outset with the HVAC, Fire, Wet Services and Bulk water and sewer for the development and are in the process of successfully handing the project whilst occupation starts.
