30 Bond Building – Sydney, Australia

This was one of the first green rated buildings back in 2005.  Its most sustainable feature is the Chilled beam system for producing cool air.  90% of the cool air comes from it and 10% is fresh air.  The “wall” is a sandstone wall that was originally cut by the prisoners in Sydney’s jails but it is used to cool the atrium.  The cool air comes down and they have crea to a shorter wall on the bottom to catch the air and the recirculate into the system.  The floors in the atrium are heated (when needed) by tubing in the floor and the floors absorb heat in the summer which helps in keeping it cool.   Some of the interior features are bamboo flooring, Goat hair rugs, raised flooring, recycle bins in the kitchens, all green waste is taken offsite to a third party – Earthpower, they have a small rainwater tank but they don’t use it much, automatic louvers that are open in the morning and by 3pm they close to reduce heat and bright sunlight and a garden roof.
