Derek Newby, LEED AP, CPHD, has returned to Diamond Schmitt Architects as the principal of its Vancouver practice. Newby brings extraordinary experience to designing mixed-use, office, and academic facilities, and is recognized nationally for his leadership in sustainable design and high-performance buildings, the firm said. For years he has advocated for low-carbon buildings, both through the application of Passive House principles to reduce operating emissions and through the use of timber to reduce embodied emissions.

Toronto-based Diamond Schmitt Architects has appointment Sybil Wa and Nigel Tai as principals with the firm. The promotion of the two senior associate architects recognizes their contribution to design excellence and skilled project management on a wide range of projects, the firm said in a press release.
