Aurecon Center, (Lynnwood Bridge Office Park, 4 Daventry Street, Pretoria, Tshwane)
SignificanceThis is the first office building in Tshwane (South Africa’s Capital city to achieve a 4 Star GreenStar SA [Office Design v1, Office Design v1] rating from the Green Building Council of South Africa (GBCSA). Sustainability is a research field high on the agenda of the City of Tshwane Metropolitan Municipality Council, making this a prominent building within the context of Tshwane and South Africa. The Executive Mayor of Tshwane, Councillor Kgosientso Ramokgopa officially opened the Building on the 15th of September 2011.

The Aurecon Group received the opportunity to relocate 1000 of their Tshwane employees from their Offices in Burnett Street, to that of a newly planned development, namely Lynnwood Bridge Office Park. This relocation would allow them to play a mojor key within the design of the building, which according to their CEO, . This allowed the group to illustrate their beliefs that states: “Part of being the best in industry includes thinking about the most pressing issues their clients face. At the moment, one of these overarching challenges is that of ‘sustainability’, and in line with this, they are committed to playing a leading role in promoting environmentally sustainable development.”

Description of site and/or structures and/or interior spaces
David Barnes, the Architect, stated that the worst traif that a building can have is to be inflexible. Therefore the Aurecon Building is adaptable to new layouts within the space, and the incorporation of new technology. He further states that the building should evolve as the company's needs grow (Kruger, 2011:61).
It can be described as an office building comprising of a concrete column and beam structure with either glazed windows or well insulated brick infill used at all 4 Facades. A service core is in the middle of the building, with each floor as a mere duplicate of each other. This allows for large open spaces in which offices, meeting rooms and hot-desks can be installed. According to Barnes (in Kruger, 2011:61) a building’s worst trait is inflexibility. Thus one can understand how the approach of a simple structure covered by a “Green” shell (Kruger, 2011:62) with the specific engineering features qualifying the Green Star rating prominently influenced the design. The building signifies modernist design stylistically as well as intent.
Main Architectural features within this design, is that of implementation of natural light. The way in which light is reflected without glare into the building is a detail quite well resolved by the 3 different skylights.
- Main Atrium
- Circulation Space
Thick insulated wall were used to keeping warm air out, when it is hot, and retaining warmth when it is cold. The Shutters has also been designed with the intent of allowing the worker to experience the outside without having to deal with 50% or more glare.
- Site was situated within 100m From the Morelleta Spruit, (Wetland Area)
- Noise, (Next to Highway)
According to Nicol Labuschagne and Martin Smith from Aurecon, the principle focuses of the engineering design were the following:
- Reducing Consumption of electricity
- Reducing Consumption of Water
- Reducing the Environmental Impact of Building Materials
- Improving the Indoor environmental Quality
- Improving the building Design.
