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,” he says. The No 1 Silo development is one of Africa’s most advanced intelligent buildings. Through innovative design solutions, combined with proven technology, the building works with the environment rather than against. It speaks to a wide range of sustainability issues and adheres to the strictest global environmentally sustainable building principles and requirements. Some of the more unique green features are the use of seawater from the Atlantic Ocean, which will be used to reject waste heat from the cooling plant and allows for significant potable water savings and improves the over-all energy efficiency of No 1 Silo the building. Heat generated from the IT server room will feed the underfloor water borne heating system to warm the reception area. Another key innovation of the building is the double glazed double skin high performance façade that has a system of automatically controlled blinds between the internal double glazed system and the external single glazed skin which will track the sun as it moves across the building. The high performance façade reduces solar heat gain while maximising the natural light penetration into the building. The blinds prevent further heat gain and also control the solar glare in the office space. The double glazing prevents any radiant heat loss or gain to the office space. One of the benefits of this façade is to maximise views and natural light throughout the building. 63
