The new 6-star GBCSA Office V1 design-rated headquarters for the Department of Environmental Affairs is located in Pretoria, capital city of South Africa. The project is a good example of how Government can lead by example through forefront sustainable innovation.The design brief called for a maximum energy consumption target of 115 kWh per square metre (sqm) per annum, giving rise to innovative design processes through Building Information Modelling (BIM) and extensive energy modelling. Innovative technologies include night flushing to enhance passive climatic strategies, while natural resources are conserved through water harvesting, solar power and hot water etc.

The Department’s environmental and sustainable ideologies was communicated through the architectural language while it demonstrates aspects of sustainable design, energy and resource efficiency through the extensive use of outdoor and indoor planting, expressive feature water collectors and a photovoltaic (PV) farm covering most of the roofs. Material selection was largely driven by sustainability, longevity and ease of maintenance.
