Green Certification

Zinner Consultants manages green certification projects for five certification systems. No matter which system is utilized, our goal to cost effectively maximize project performance. We focus on reducing operating costs and carbon emissions over the life of the project while increasing project value, marketability, and occupant health and performance.



We have over 50 LEED certified projects, including a number of firsts: first Platinum museum in the world; first certified sound stage; first two Core & Shell projects in the City of Los Angeles (one ground up, the other adaptive reuse); and the first zero net energy (ZNE) classrooms in Los Angeles. As a LEED Proven Provider, we are able to fast-track the LEED certification process through direct communication with senior LEED reviewers at the Green Building Certification Institute (GBCI) and accelerate project reviews.



Kids learn better in green or high performing schools. It only makes sense that healthy indoor air, daylight and good acoustics support improve education outcomes. The CHPS K-12 criteria was developed in California and is now national. Its priorities, in order of importance, are 1) student performance and student and staff health; 2) minimizing operating costs through energy and water efficiency, and 3) environmental stewardship. ZC Principal John Zinner is a long time Board member and Co-Chair of the CHPS National Technical Committee.



The WELL Building Standard is the first to focus on occupant health and wellness. The antecedent to WELL, if there is one, is CHPS. WELL addresses seven “concepts:” air, water, nourishment, light, fitness, comfort and mind. Certification documentation is relatively simple. The key is passing the onsite third-party testing conducted by trained analysts. 



Like WELL, Fitwel focuses on optimizing buildings to support health. Fitwel for residential includes multifamily buildings and residences; Fitwell for workplaces addresses multi-tenant, single-tenant, and commercial interior spaces.



Envision helps create sustainable civil infrastructure projects. It serves both as a planning and design tool, and a certification system for completed projects. It rates the community, environmental and economic benefits of all types and sizes of infrastructure projects.
