LEED: Transforming the market

The LEED Green Building Rating System for Core and Shell Development (LEED-CS) is for designers, builders, developers and new building owners who address sustainable design for new core and shell construction.

LEED-Core and Shell

LEED Core and Shell is used to evaluate building projects where the owner does not control the interior design and fit-out. 

It is not available for those owners who wish to achieve exemplary performance in the Core and Shell while failing to meet LEED standards in the building interiors fit out.  Those owners who have control over both the core and shell and interiors elements need to apply under LEED for New Construction.

LEED: Giving Developers a Competitive Advantage

For the Core and Shell developer to gain market advantage from their LEED initiatives, they must be able to use their LEED-CS designation as part of this differentiation. 

LEED-CS responds to this

need by allowing for “pre-certification” prior to the construction of the building.

LEED-CS: Energy and Atmosphere Credits

• LEED-New Construction has 16 possible EA credits. LEED-CS emphasizes these opportunities but makes no additional changes.

Calpine Center, Houston

LEED-CS: Materials Credits

LEED-CS ties with LEED for Commercial Interiors, particularly in the specification of environmentally-friendly materials for construction and fit out. No changes in LEED-CS from LEED-NC.

LEED-CS: Indoor Environmental Quality Credits

LEED-CS creates a base building that supports tenant choices in regard to indoor environmental quality issues by addressing controllability of systems and indoor pollutant source control. No changes from LEED-NC.

LEED-CS: Innovation & Design Process

Opportunities abound for creativity by design teams in LEED-Core and Shell.

Pilot projects have

exhibited exceptional performance in many credit categories.
