Intent

The LEED rating system is designed to evaluate buildings, spaces, or neighborhoods of a certain size. The LEED requirements do not accurately assess the performance of projects outside of these size requirements.

Requirements

All LEED projects must meet the size requirements listed below.

LEED BD+C and EB:O&M Rating Systems

The LEED project must include a minimum of 1,000 square feet (93 square meters) of gross floor area.

LEED ID+C Rating Systems

The LEED project must include a minimum of 250 square feet (22 square meters) of gross floor area.

LEED Neighborhood Development Rating Systems

The LEED project should contain at least two habitable buildings and be no larger than 1500 acres.

LEED for Homes Rating Systems

The LEED project must be defined as a “dwelling unit” by all applicable codes. This requirement includes, but is not limited to, the International Residential Code stipulation that a dwelling unit must include “permanent provisions for living, sleeping, eating, cooking, and sanitation.”

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

LEED Interpretation
Inquiry:

Can dormitories and assisted living facilities pursue LEED for Homes/Residential certification?

Ruling:

Yes. Dormitories and assisted living facilities can pursue LEED for Homes certification based on the building type they align with. These buildings are typically identified by the presence of a central kitchen facility, and the fact that they fall outside of the scope of ASHRAE Std. 62.2. If a bedroom has its own cooking area and/or bathroom, that space should be treated as a multifamily unit within a multifamily building. If multiple bedrooms share a private living area, bathroom, and/or kitchen that is not accessible to the rest of the building occupants, that suite of rooms should be treated as a multifamily unit, and the building should be treated as a multi-family building. Non-unit spaces should meet all LEED prerequisites and the same credits as the worst case unit, where applicable.

A few additional notes:
- Each dwelling unit must be compartmentalized (i.e. isolated from common spaces and each other).
- Central kitchens and common bathrooms are required to meet the local exhaust requirements in ASHRAE Standard 62.1. Common residential associated spaces do not need to be included in the Home Size Adjuster but are required to meet the ventilation requirements in ASHRAE Standard 62.1 and must meet all LEED prerequisites and the same credits as the worst case unit, where applicable.
- In-unit spaces are still required to meet the ventilation requirements in ASHRAE Standard 62.2.
- Buildings that do not meet the definition of single family or multifamily may be allowed to use a Home Size Adjuster of Zero. Consult GBCI with questions on registration, space definition, and home size adjuster questions.
