We compile guidelines to help make buildings more energy-efficient, resource-efficient and environmentally responsible. We project manage the installation of systems to ‘green’ buildings. NCC is a member of the Green Building Council SA, and has experience in green building methods including: passive solar design, solar power, grey water recycling, rain water harvesting, recycling and composting. We are "greening" our head office, by reducing electricity consumption, water consumption and recycling our waste.
