The National Energy Code of Canada for Buildings (NECB) sets out technical requirements for the energy efficient design and construction of new buildings. It is published by National Research Council (NRC) and developed by the Canadian Commission on Building and Fire Codes in collaboration with Natural Resources Canada (NRCan). 

The NECB has two main versions 2011 and 2015. The 2015 edition broadens the scope to address all service water and introduces requirements for pressure-sensing controls which reduce the short-cycling of booster pumps when the demand for water is low. Overall there are 90 changes to improve energy performance of buildings included in 2015 version when compared to 2011 version. 

Cove.tool supports both of the NECB versions i.e 2011 and 2015. It also takes care of selecting default version of NECB accepted by different states in Canada when you input the location of the project.
