Core and Shell

LEED^® Canada for Core and Shell Development (CS) is derivative of LEED Canada for New Construction (NC) and applies to buildings where less than 50% of the building area will be fit-up to LEED Canada NC requirements prior to certification.

Like the LEED Canada NC rating system, LEED Canada CS applies to new construction and major renovations of commercial and institutional buildings, ie., buildings regulated by Part 3 of the National Building Code. Generally, projects using LEED Canada CS are office occupancies where the developer has no control over the final interior fit-ups of the tenant.

LEED Canada CS 2009

The CaGBC is happy to announce that registration for LEED Canada for New Construction and Major Renovations (NC) 2009 and LEED Canada for Core and Shell Development (CS) 2009 opened June 21, 2010. These new rating systems offer many advantages, including:

Consolidation of documentation: all the Application Guides and relevant CIRs have been incorporated.
Updated reference standards: the new rating systems refer to more current reference standards.
New and updated pathways: several alternative credit compliance pathways have been introduced, and thresholds have been adjusted to better reflect the state of the industry.
Re-weighted credits: the number of points that may be earned for each credit has been re-evaluated using a more scientific approach, resulting in greater emphasis on preventing climate change.
Familiarity: the majority of credits have not substantially changed.
Faster certification: the audit round of the certification process has been eliminated, and streamlined compliance pathways are available for some credits.

Projects registering as of June 21 2010 will be registered under the 2009 versions, while projects registered prior to this date may switch to the new rating system.
