The City of Melbourne, a C40 city, has embarked on an innovative financing effort for commercial building retrofits – an achievement supported from its inception by expertise across C40's network of staff, cities and partners.
Seattle seized the opportunity to improve sustainability during a time of unprecedented capital improvement that began in the late ‘90s. It did this by first requiring all new City buildings over 5,000 square feet to meet new LEED™ (Leadership in Energy and Environmental Design) building ratings that measure the sustainability of buildings, and by providing financial, height and density bonuses for private projects meeting LEED™. Subsequent initiatives have included priority permitting, energy benchmarking and an updated policy for City buildings. As a result it now has one of the highest concentrations of sustainable buildings in the country and a powerful sustainable building industry.
Melbourne Council House 2 (CH2) is a multi-award winning and inspirational building that has reduced CO2 emissions by 87%, electricity consumption by 82%, gas by 87% and water by 72%. The building purges stale air at night and pulls in 100% fresh air during the day. The building exterior moves with the sun to reflect and collect heat, and turns sewage into usable water. The building has improved staff effectiveness by 4.9% and will pay for its sustainable features in a little over a decade.
Heidelberg is at the forefront of environmental protection in Europe and has cut CO2 emissions by over 15,000 tons per year in municipal buildings since 1993. The city has developed a comprehensive energy management system for local authority properties and has been involved in a wide range of projects for sustainable development.
