Six stars for V&A Waterfront property development
The new No 1 Silo office building under construction at the V&A Waterfront has been awarded a six-star Green Star SA design rating by the Green Building Council of South Africa.

The office development is South Africa's latest - and largest - green office building, and is only the second to get a six-star rating and the first in the Western Cape.
"Sustainable development and green operations are fundamental to the V&A Waterfront's overall development strategy," says David Green, chief executive of the V&A Waterfront.
"We have adopted a rigorous approach to green construction and sustainable design principles and the efficient use of natural and energy resources."
The Green Star rating system was established by the Green Building Council of SA in 2008 to evaluate potential environmental performance of buildings.
Green buildings should be energy and resource efficient and environmentally responsible.
Design, construction and operational elements need to be combined to reduce significantly or eliminate the negative impact on the environment and building occupants.
Green buildings use resources more efficiently while creating
Thealthier and more productive environments for people to live and work in. The No 1 Silo development is due for completion in June. One of Africa's most advanced intelligent buildings, the development has been designed in line with strict global environmentally sustainable building principles.
Features include the use of water from the Atlantic, which will help reduce waste heat from the cooling plant, allowing for significant savings on potable water and improving the overall energy efficiency of the building. Heat generated from the IT server room will feed the underfloor waterborne heating system that will warm the reception area.
The high performance double skin façade has a system of automatically controlled blinds. Set between the internal double glazing and the external single-glazed skin, the system will track the sun as it moves across the building. The façade reduces solar heat gain while maximising natural light penetration. The blinds also prevent heat gain and control solar glare in the office space. The double glazing prevents radiant heat loss and gain in the office space.
The underfloor mechanical air-conditioning system allows energy efficiency and a quality indoor environment.
The system supplies cool fresh air from the raised floor, which then warms as it rises and is extracted at ceiling level, preventing the build-up of pollutants.
The building ensures optimal indoor environment quality to promote the health and wellbeing of those working inside, says Green.
"Building occupants will have striking views and ample natural ligh. Care has been taken to specify paints, wood products and carpets that contain no har mful compounds that may be inhaled by occupants. The building has also been designed to provide outdoor environments, like a roof garden with indigenous plants that overlooks the harbour and the City Bowl. A small herb garden will contribute to the food prepared in the kitchen, and composting units will recycle organic kitchen waste."
Low-flow water fittings have been specified to promote water efficiency, and a grey water system has been installed to save potable water. Waste water from washbasins and showers will be collected, treated, and reused for flushing toilets.
No 1 Silo has been designed with efficient and environmental lighting in mind. All fluorescent fittings have energy efficient high frequency ballasts.
Sensors ensure that lights are on only when they need to be, and at the correct levels of illumination. Care has been taken to ensure that no night lighting is directed towards the sky, to reduce light pollution.
More than 70 percent of waste generated on site is recycled.
