Kirstenhof Office Park, South Africa

Aurecon appointed Environmentally Sustainable Design consultant

The Kirstenhof Office Park is situated on Witkoppen Road in Johannesburg and it comprises four, two-storey high office blocks that function as a single building by virtue of being connected by a core quad area that covers a single, shared basement.

The elegant Cape Dutch designed building is 20 years old and is used for both corporate office space and tertiary education facilities.

Growthpoint appointed Aurecon as the Environmentally Sustainable Design (ESD) consultant for the 3 837 m² multi-tenanted office park refurbishment. Aurecon was tasked with improving occupancy comfort levels as well as reducing the energy and water consumption of the building.

Some of the green features of the project include energy efficient lighting, flow restrictors on all taps, a storm water management plan to limit the disruption of natural hydrology, as well as a waste management plan that will ensure that more waste is diverted from landfills.

Aurecon conducted occupant, thermal and transport mode surveys in the project’s twelve month performance period and this information can be used to further enhance the building occupants’ experience and comfort levels.

There is a large amount of natural light in the buildings, as a result of the numerous windows throughout the office blocks. Glare from direct sunlight was reduced by installing high performance blinds and we were also able to prove that 60 per cent of the usable area has direct line of sight to the outdoors. The large trees, building orientation, landscaping and the high Solar Reflectance Index value of the office park’s facade has enabled the building users to make use of the natural cross ventilation in the building instead of using air conditioning. These factors led to a lower running cost and reduced energy consumption on heating and cooling.

On 27 May 2015, the Green Building Council of South Africa (GBCSA) awarded its one hundredth Green Star SA certification to the Kirstenhof Office Park.
