It is the first residential development in South Africa assessed using the Green Building Council of South Africa's (GBCSA) version one rating tool. Prior ratings were under the pilot scheme.
Commenting on the rating, CEO David Green said, "Sustainability is balancing the human need for natural resources while preserving the environment so that these needs can be met not only in the present, but also for generations to come. Sustainability is no longer just a trend, but a necessity. This is the standard we align to. Sustainable building and greening practises are at the core of our business practises and past, current and future developments at the V&A Waterfront."
The GBSA developed the Green Star rating system to provide an objective measurement for green buildings and to recognise and reward environmental leadership. Sustainable buildings are designed and constructed according to high environmental standards, thereby minimising energy demand, reducing water consumption and making use of materials with a low impact on the environment. The aim is to create healthier and more productive environments for people to live and work in.
The materials employed in No2 Silo are low energy lighting, high performance glass that provides thermal and acoustic insulation as well as sustainable timber sources that are FSC-certified. No.2 Silo also uses sea water as a cooling agent, a centralised solar heated hot water system and external solar shading. Water-efficient showers, toilets and energy and water-efficient kitchen appliances, energy saving devices and even a website allowing homeowners to track and manage their water and energy consumption, are all included.
The area is named after the original Grain Silo building. Completed in 1924 by SA Railways and Harbours, its location was driven by its connectivity to the docks and the resultant rail infrastructure. The building was such a principal part of the city's urban character that it has been heritage listed by the authorities. Silo Square will embrace the historic landmarks of the former grain elevator and silo buildings which will become the centrepiece of a public plaza that will incorporate a combination of public space and commercial development.
"The V&A Waterfront is an extension of the city and a neighbourhood within the city. The development of Silo Square honours the initial vision of the V&A Waterfront to remain the most desirable place for Capetonians to live, work, shop, play, stay and eat and to be an integral part of the City of Cape Town and of the on-going regeneration of the docklands," says Green.
The 4-star Green Star rating comes shortly after No1 Silo, an 18,000 square metre commercial building and the new Allan Gray head office, was awarded a 6-star Green Star rating for design.
