Zero/Six Consulting, LLC was founded in 2003 by Bill Coltzer Jr., AIA in response to an industry wide need for higher performing and cohesive building envelope systems. Since its establishment, Zero/Six has become a leader in delivering innovative solutions for the creation and maintenance of better building envelopes. A firm focused solely on building envelope integrity, we have assembled a staff of professionals with diverse skill sets — Architects, Engineers, LEED Green Associates, Registered Roofing Observers (RRO), Project Managers, and Field Specialists — to achieve the necessary “whole building” approach.
