NRC NECB-2015
National Energy Code of Canada for Buildings 2015
Product Details
The National Energy Code of Canada for Buildings 2015 (NECB) sets out technical requirements for the energy efficient design and construction of new buildings. 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 demand for water is low. Other HVAC and service water changes include equipment efficiency regulation of heat rejection equipment, such as cooling towers and (standalone) condensers, heating performance requirements for gas-fired outdoor packaged units and updated minimum pipe and duct insulation requirements. Lighting power density values and controls have been updated with more stringent lighting allowances and additional requirements for common spaces and exterior applications. The performance path modeling rules and guidance have been updated to reflect the changes to the prescriptive path as well as more current typical use profiles of buildings. Application of the code for residential and small buildings has also been clarified.
Preface
The National Energy Code of Canada for Buildings 2015, together with the National Building Code of Canada 2015, the National Plumbing Code of Canada 2015 and the National Fire Code of Canada 2015, is an objective-based National Model Code that can be adopted by provincial and territorial governments. Codes Canada are developed by the Canadian Commission on Building and Fire Codes (CCBFC).
In Canada, provincial and territorial governments have the authority to enact legislation that regulates building design and construction within their jurisdictions. This legislation may include the adoption of the National Energy Code for Buildings (NECB) without change or with modifications to suit local needs, and the enactment of other laws and regulations regarding building design and construction, including the requirements for professional involvement.
The NECB is a model code in the sense that it helps promote consistency among provincial and territorial building codes. Persons involved in the design or construction of a building should consult the provincial or territorial government concerned to find out which construction requirements are applicable.
This edition of the NECB succeeds the 2011 edition.
The development of the NECB 2015 has been a collaborative effort involving the National Research Council of Canada (NRC), Natural Resources Canada (NRCan) and other stakeholders. NRCan’s financial and technical contributions will improve the energy efficiency of new buildings and reduce greenhouse gas emissions. The NECB 2015 will contribute to long-term benefits for both Canada’s economy and the environment.
