Episode 19. AJ Climate Champions with Hattie Hartman. This week we continue our focus on reuse with a step-by-step approach to tagging the components of an existing building so that they can be dismantled and reused, just like Lego blocks. Hoolahan explains how she collaborated with a multidisciplinary team to develop an open source, design-led approach to material passports for retrofit, an initiative that won her this year’s AJ100 Sustainability Champion award.
