SYDNEY MAINSTER - Vice President of Sustainability

Sydney brings over 16 years of professional and academic architecture, design, and construction experience to The Durst Organization. As Director of Sustainability, her primary role is to support the company leadership’s vision for sustainability in ground-up development projects, existing building renovations, and building management. Working cross-functionally with the Marketing, Leasing, Engineering, Operations, and Construction Departments, Sydney develops strategies for implementing sustainability guidelines, setting targets, and maximizing tenant engagement.

Sydney works closely with design consultants, construction teams, and manufacturers to ensure product selection, procurement, and installation all meet established performance and sustainability criteria—not only to achieve outcomes on current building projects, but also to improve environmental standards and innovation in the industry at large.
