WSP in Africa achieved a 4-Star Green Star SA As Built rating, including a keen focus on Local Connectivity, for Rosebank Towers – setting another benchmark in sustainable buildings.
Rosebank Towers is located in the heart of Rosebank central business district, at 15 Bierman Road. As a brownfield project, the project has a total gross floor area of around 25 500 m2, where the original buildings on the site were demolished to make space for the new development - 94% of all construction waste was diverted from landfill.
Additionally, the building is also in close proximity to an array of amenities, from schools to medical facilities, restaurants, spas, retail outlets, sport facilities and, great connections to transportation nodes – including the Gautrain - within allowable walking distance. This inspired the decision to target a local connectivity innovation point, by means of exceeding the Green Star SA Benchmarks, which has never been rewarded within the Green Star framework. The South African Green Star rating guidelines requires that a building has convenient, safe access to a minimum of four prescribed listed amenities - and in the motivation WSP submitted to the GBCSA on this project provided evidence that the Rosebank Towers in fact has access to all the prescribed listed amenities and more.
The scenario case study provided evidence of the benefits for the environment through the reduction of automobile emissions - due to the close proximity of all the amenities, the number of automobile trips that would usually be required are significantly reduced. This also proved to be greatly beneficial for the buildings occupants, as less time spent travelling creates opportunity to significantly reduces the perceived stresses of time constraints and traffic annoyance.
