All homes participating on the Certified Green Homes track of the GreenBuilt Home Tour are pursuing or have received one or more of the following green home program certifications/verifications. All of the home programs below require some nature of third-party verification.

DOE Zero Energy Ready Home
DOE Zero Energy Ready Homes—formerly DOE Challenge Home— are verified by a qualified Zero_Home_MASTER_Mark_perfect    third-party and are at least 40%-50% more energy efficient than a typical new home, and goes beyond ENERGY STAR. A DOE Zero Energy Ready Home is a high performance home which is so energy efficient, that a renewable energy system can offset all or most of its annual energy consumption.  Learn more at

A relatively new entry-level green building program called ecoSelect™ is proving to be a straightforward ecoSelectlogo_highresresource for builders wanting to break into the market. The intent is to provide builders with an “on-ramp” to green building programs, and to help fill in the gap between building/energy code requirements and more complex green building programs. With over 1,000 certifications to date since its launch in 2013, the program’s simplicity is part of its appeal. Learn more »

ENERGY STAR certified homes are independently verified to meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes save money on utility bills, provide a more comfortable living environment with better indoor air quality, and help protect the environment. Learn more »

This program applies to both remodeling and new construction and ensures healthier, more durable GreenStarlogohomes that save energy and water thus reducing the cost of living and improving comfort.GreenStar looks at how green measures are systematically applied to the 7 components of a home including, Outdoor/Site, Building Envelope Systems, Mechanicals, Electrical/ Lighting, Plumbing Systems and Fixtures, Finish Materials and Coatings and Waste Management.

HERS Rating
A measure that cuts across green certifications, the Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance. A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home. Learn more »

LEED for Homes
LEED for Homes is a third party-verified rating system that promotes the design and construction of LEEDlogohigh-performance green homes. LEED measures a home’s performance based on eight categories: site selection, water efficiency, materials & resources, energy & atmosphere, indoor environmental quality, location & linkages, awareness & education, and innovation. Each LEED-certified home undergoes onsite inspections and thorough performance testing to ensure proper performance.

Living Building Challenge
The Living Building Challenge™ is the deepest shade of green, calling for the creation of building projects at all scales that operate as cleanly, beautifully and efficiently as nature’s architecture. To be logo_lbccertified, projects must meet a series of ambitious performance requirements over a minimum of 12 months of continuous occupancy. The Living Building Challenge is comprised of seven performance areas: Place, Water, Energy, Health & Happiness, Materials, Equity and Beauty.

NAHB National Green Building Standard
The National Home Builders Association’s National Green Building Standard™ certification provides independent, third-party verification that a home, apartment building, or land development is designed and built to achieve high performance in six key areas: Site Design, Resource Efficiency, Water Efficiency, Energy Efficiency, Indoor Environmental Quality, and Building Operation & Maintenance.

Passivhaus Institut – EnerPHit
Passive House buildings are characterized by especially high levels of indoor comfort with minimum energy consumption. EnerPHit is the established Standard for refurbishment of existing buildings using Passive House components. Despite the slightly higher energy demand, it offers virtually all the advantages of the Passive House Standard. A Passivhaus Institut building can be found on every continent and in every climate zone including Antarctica. Learn more »

PHIUS+ 2015 Passive Building Standard

PHIUS+ Certification (also known as Passive House) combines a thorough passive house design verification protocol with a stringent Quality Assurance and Quality Control (QA/QC) program and on-site testing.  Projects certifying under this program are required to meet cost-optimized aggressive climate specific energy targets.  PHIUS+ Certification uses the Energy Star and DOE Zero Energy Ready Home programs as prerequisites for single-family projects.

The Water Efficiency Rating Score (WERS) is a water performance evaluation tool that is currently being piloted across the country through the GreenBuilder® Coalition. Only measurable parameters were established as the foundation of the WERS, along with a scoring scale of zero to 100 with zero being the most desirable. The tool scores a home’s water use for both indoor and outdoor applications with the potential for offsets via on-site rain water or grey water collection. Learn more »,
