This document evaluates a study case of a sustainable commercial building called "30 The Bond" in Sydney, Australia. It achieved a high performance and low energy consumption through designing for occupants with sustainable criteria and an adequate site analysis. The site had constraints like only three exposed facades and an historic sandstone wall on the fourth facade. This wall provided thermal mass and was incorporated into the building design. An external shading system and double facade with intelligent controls were used to reduce energy consumption while improving indoor comfort and performance, considering the site's sun exposure, winds, and urban context. Through its design strategies, 30 The Bond achieved a 5-star energy rating from the Green Building Council of Australia's rating tool.
