Cape Town’s Portside awarded another 5 Star Green Star Rating for its green building credentials

 Cape Town’s Portside

In recognition of its commitment to sustainable investment in green buildings, Portside, an Old Mutual co-owned building in the Cape Town CBD, has achieved a 5 Star Green Star rating for its construction efforts as a premium green building, Old Mutual Property has announced. The award, a 5 Star Green Star Office v1 AS-BUILT certification by the Green Building Council of South Africa, comes after the building has already been awarded a 5 Star Green Star rating for Design in 2013. The building is the only high rise building in South Africa to be 5 Star Green Star rated. 

A joint initiative between Old Mutual and FirstRand Bank, the R1.6bn project is situated in the financial district of Cape Town’s Foreshore. The building was designed by DHK and Louis Karol Architects to represent a thoroughly green high rise development. It features 32 floors, comprising over 52 000 m² of prime AAA office space, 1 200 m² of retail and banking space on the ground level and 1 382 parking bays.

“We are incredibly proud of the recognition through these ratings of Portside’s green building credentials by the Green Building Council of SA,” said Faieda Jacobs, Regional Manager at Old Mutual Property. “This building is an important showcase for Old Mutual Property’s sustainable investment strategy through an expanding green building portfolio, as well as being a key example of how green and social imperatives can make a difference,” she says.

Both Portside’s 5 Star Green Star Office v1 AS-BUILT and Office Design ratings are based on a number of features which include the following:

  • A high performance building façade which allows less heat in during the summer and also allows less heat out in the winter
  • Over 95% high efficient LED Lighting – Portside is the first building in SA to boast LED lights to all parking areas as well as the offices
  • Passive Infrared sensors that respond to ambient lighting conditions and switch off lights in unused zones
  • High performance chilled water plant which uses less energy
  • Air handling units fitted with economy cycle to reduce air-conditioning costs
  • Water efficient fittings
  • Water recycling in terms of both Rainwater harvesting and Greywater harvesting
  • Water and electricity sub-metering together with an intelligent building management system that controls the heating/ cooling, ventilation, lighting and water usage throughout the building

The rating doesn’t take into account the green credentials of the building’s tenants; however Portside has rolled out a system of soft green leases for the initial leasing stages, which will impact how the building is used. A green lease follows the premise that a building is only truly green or sustainable if it is operated and managed the way it was intended to be.
