Step 1 - Choose a rating system based on construction type

Determine which construction type the project falls into. Be sure to consider the building in its entirety or the complete interior space.

Many projects will be undergoing construction work that does not fall neatly under one construction type definition (such as ‘major renovation’ or ‘interior fit-out’). It is the project team’s responsibility in this case to make a reasonable determination on which definition best fits their project. A strict application of each definition is not required.

Complete Construction

These rating systems are appropriate for buildings that are undergoing new construction or major renovation (or gut rehab, for low- and mid-rise residential) and a complete interior fit-out. There are five rating systems in this category.

Core and Shell Construction

This rating system is appropriate for buildings that are undergoing new construction or major renovation on its exterior shell and core mechanical, electrical, and plumbing units but NOT a complete interior fit-out. There is only one rating system in this category.

Commercial Interior Construction

This rating system is appropriate for commercial Interior spaces that are undergoing a complete interior fit-out of at least 60% of the certifying gross floor area. There are two rating systems in this category.

Existing Buildings: Limited Construction

This rating system is appropriate for existing buildings undergoing improvement work or little to no construction. There is only one rating system in this category.
