Last spring, several members of Group2 Architecture Interior Design, revisited their plans for an office space in Edmonton after hearing a wallboard that absorbs one of the highest concentrations of volatile organic compounds (VOCs)—formaldehyde. The firm’s new lease was for a 478-m2 (5150-sf) top floor plate in a nine-storey building. They were to completely remodel the space, adding new framework and drywall, among other things.
