As office buildings age, they become less efficient, producing higher CO2 emissions and consuming higher amounts of energy and financial resources. With 85% of all Australian office stock older than 10 years, the commercial ‘office’ building is the most significant building type in terms of energy efficiency and emissions reduction. There are huge...
