Characteristics of a LEED Home
A LEED home is designed to use 30-50% less energy and 20-50% less water than a code-built home, while providing 50% more fresh air and contributing 50-75% less waste to landfills.
Veridian Homes
LEED for Homes Checklist
A more prescriptive approach to LEED, including 136 Credits and 18 Prereqs. A Home Size Adjuster determines points thresholes. Predicated on ENERGY STAR v2 certification.
Roles in LEED for Homes
LEED for Homes follows the same implementation model as ENERGY STAR, using approved Providers to oversee the work of Raters. “Builders” have primary responsibility for design and construction.

Eligibility: New or Gut Rehab
St. Finbar
To qualify for ENERGY STAR and LEED for Homes, projects must be gutted to the structure on at least one side of exterior walls to allow for air sealing and insulation install and inspection, and major systems must be replaced.
Eligibility: Residential Amenities
Overlook at Clipper Mill
LEED for Homes projects must be >50% residentially associated area, and must include cooking facilities.
Eligibility: Dwelling Units
EcoGreen Townhouses
Any number of dwelling units is acceptable in LEED for Homes. For group home situations, 10 or more bedrooms follows multifamily while 9 or fewer is treated as single family.
Eligibility: Height
Single family projects of any height can use LEED for Homes. Multifamily projects up to six stories can use LEED for Homes and its adaptations.
82nd Street Townhouse
LEED for Homes Midrise Multifamily
Melrose Commons Site 5
An adaptation for 4-6 story buildings that retains the prescriptive options but incorporates energy standards and other credits from the commercial standard to specifically address this underserved market.
Eligibility: Building Systems
University Village Apartments
Central HVAC systems at three stories or less follow regular Homes. Central systems at four-six stories follow Midrise and ASHRAE 90.1.
Eligibility: ENERGY STAR®
ENERGY STAR v2 is a prerequisite of LEED for Homes 2008. LEED 2012 in Nov 2012 will require ENERGY STAR v3. Midrise is similar to ENERGY STAR Multifamily Highrise.
Eligibility: Use Type
The Franciscan Sisters Motherhouse
LEED for Homes does not explicitly require R code designation, and has allowed some institutional use types, but only R projects can earn ENERGY STAR Homes.
Decision Time
LEED for Homes
orLEED for New Construction?
HfH-NYC Atlantic Avenue Homes
Pros - LEED for New Construction
LEED for New Construction aligns with certain incentive programs, is more familiar to project teams, and may be more appropriate for institutional projects. Also can have more lenient IEQ requirements.
The Solaire
Pros - LEED for Homes
LEED for Homes is as-built, focuses on residential priorities, serves smaller buildings, and can carry smaller soft costs. Aligns with ENERGY STAR programs for single and multifamily, as well as NY Green Residential Building Program.

Summary: Non-trad LEED Homes
LEED for Homes is being used far beyond the white picket fence! Projects that are primarily residential in scope are benefitting from lower soft costs and more residentially focused requirements in this rating system.
