National Energy Code of Canada for Buildings: 2025

Date published

<p>The National Energy Code of Canada for Buildings: 2025 (NECB) sets technical requirements that address the protection of the environment in the design and construction of new buildings and in subsequent alterations. The 2025 edition of the NECB includes the following updates:</p>
<ul>
<li>Expansion of the environment objective to address greenhouse gas emissions;</li>
<li>Introduction of a harmonised framework that aims to reduce the operational greenhouse gas emissions of buildings, offering provinces and territories a harmonised pathway to reduce emissions over time by choosing the performance level that best suits their needs;</li>
<li>Introduction of energy efficiency requirements for the alteration of existing buildings, offering building officials a harmonized framework to enforce code requirements in retrofits;</li>
<li>Updated requirements to account for the impact of thermal bridging through the building envelope Introduction of an energy use intensity path for compliance with energy performance tiers, providing builders with an additional option to demonstrate compliance that recognizes the inherent efficiencies of smaller, more compact housing forms; and</li>
<li>Inclusion of projected climatic data, which anticipates climate trends over the next 50 years, so buildings are better prepared for future climate conditions in Canada.</li>
</ul>

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

The management and allocation of funds, assets and investments to meet various objectives
