Zero Carbon Building Standards

A made-in-Canada solution

CAGBC’s Zero Carbon Building™ (ZCB) standards are a made-in-Canada framework that makes carbon the new measure of building innovation. Among the world’s first zero-carbon building standards, they recognize the importance of building emissions in reaching national climate commitments. The ZCB standards are an important tool supporting the green building sector’s efforts to decarbonize Canada’s buildings.

What is a zero-carbon building?

A zero-carbon building is highly energy-efficient and minimizes greenhouse gas emissions from building materials and operations. Until all emissions can be eliminated, high-quality carbon offsets can be used as a counterbalance.

The ZCB standards define low-carbon design and operational performance for buildings. They offer both rigour and flexibility, opening the door for all buildings to minimize their climate impact. Buildings of all types, from office towers to arenas, warehouses, multi-unit residential buildings, and schools, have been certified under the standards.

Zero Carbon Building Performance Standard

The ZCB-Performance Standard™ is used to demonstrate that a building has achieved zero-carbon operations. It requires verification annually.

Zero Carbon Building Design Standard

The ZCB-Design Standard™ guides the design of new buildings or retrofits of existing ones. It offers a pathway to ensure buildings can achieve zero-carbon once in operation.

Events and education

The Accelerating to Zero series of events and education are specific to zero-carbon buildings. As Canada ramps up efforts to reduce carbon, the building sector must have the knowledge and skills necessary to build to zero and to take advantage of the new opportunities afforded by our new, low-carbon economy.
