Zero Carbon Building Standard

CaGBC’s Zero Carbon Building Standard is Canada’s first green building program to make carbon emissions the key indicator for building performance.

Zero Carbon Building – Design

The Zero Carbon Building Standard provides a path for both new and existing buildings to reach zero carbon, with unique requirements for each. New construction and major retrofit projects earn Zero Carbon Building – Design certification by modeling a zero carbon balance, highly efficient envelope and ventilation systems to meet a defined threshold for thermal energy demand intensity, and onsite renewable energy systems capable of providing a minimum of 5% of building energy consumption. Project teams are required to evaluate energy use holistically, including impacts on peak electricity, and determine the GHG emissions associated with structural and envelope materials.

Zero Carbon Building – Performance

At its heart, the program is about demonstrating a zero carbon balance in building operations year after year. Buildings that achieve a zero carbon balance and meet the other requirements for existing buildings earn Zero Carbon Building - Performance certification. This certification is awarded based on a twelve month period of operations, and performance must be verified annually. Project teams are required to evaluate energy use holistically, including impacts on peak electricity, and determine the GHG emissions associated with structural and envelope materials. Recognizing the inherent challenges to retrofitting existing buildings, this certification does not require a minimum of onsite renewable energy or a minimum level of thermal energy demand performance.

 

Education: Zero Carbon Building Standard Workshop

CaGBC offers a half-day workshop that introduces participants to zero carbon buildings, with particular emphasis on the CaGBC's Zero Carbon Building (ZCB) Standard. Participants will be equipped with important foundational knowledge, as well as an understanding of how the ZCB Standard could potentially be used for their current or future projects. This workshop provides the opportunity to learn from a subject matter expert in a facilitated environment. Exercises and group discussion helped to reinforce the material. Topics covered include the requirements of the Zero Carbon Building Standard for both new and existing buildings:

  • The zero carbon balance;
  • The zero carbon transition plan;
  • Thermal Energy Demand Intensity (TEDI);
  • Energy Use Intensity (EUI)
  • Peak demand;
  • Renewable Energy; and
  • Embodied carbon
