Leadership in Energy and Environmental Design (LEED) is setting the standard for sustainable infrastructure. Projects like the GO Transit Network Operations Centre have achieved LEED Gold by focusing on every detail, from using FSC-certified wood to installing electrochromic glass that reduces energy use. The results are impressive: the centre achieved a 41% annual energy cost reduction and diverted over 75% of construction waste from landfills. These projects prove that environmental responsibility and high-performance design go hand in hand.
