Wathen Castanos Hybrid Homes, according to the EVHA judges, has "found a niche
in a difficult market and is building high efficiency homes that are
competitively priced within the market." As the judges further note, "Their
product is well thought out and the features selected closely adhere to the
company's vision." In achieving its goals, the production builder—which plans
10 other homes using the same specifications—works closely with trade
contractors in the design process and relies on checklists and other quality
control mechanisms to ensure that specifications are precisely met. Through
this cooperative process, the company has found trade partners who share its
belief in building a quality product through building science.

With its first Existing Home EVHA entry, Clifton View Homes demonstrated its
ability to translate the sound building science techniques and quality control
mechanisms that it uses for new home construction into a remodeled home design.
Starting with the design process, the EVHA judges report, "The builder's
effectiveness was very apparent." Energy modeling, done early in the project,
was used in the decision making process. As a result, the builder and the
customer got "terrific bang for the buck." To keep true to the design, regular
site meetings, checklists, and trainings were used to ensure quality control
throughout the construction process. To date, the effort seems to have paid
off: despite a 10% increase in square footage, utility bills have dipped to
one-third of what they were prior to renovation.

Cobblestone Homes has married high performance details—which, as the EVHA judges
note, include exceptional building envelope, HVAC, and water heating
systems—with a comprehensive construction management process to create a home
marketed as Michigan's First Affordable Net Energy Zero Home. Through a
partnership with several manufacturers, Cobblestone Homes has created a
veritable building science museum and education center that includes over 60
interactive displays. Yet it hasn't forgotten why it is in business: its
exceptional customer relationships include five formal tours scheduled
throughout the construction process and follow up visits at one week, 60 days,
and 1 year after occupancy.

What really makes Clifton View Homes stand out, according to the EVHA judges,
are "the systems, the team focus, and the depth of experience and passion.
These folks care, and it shows!" By encouraging a "culture of partnership" and
paying "fanatic attention to detail," the company is able to create a high
performance product within a reasonable price point. Through the custom home
building process, the company puts forth a tremendous effort to get buy-in from
customers, and then follows through to ensure customer satisfaction. In short,
say the EVHA judges, Clifton View Homes "gets the idea of a comprehensive
approach to energy efficient building."

According to the EVHA judges, Ferrier Custom Homes creates "excellently crafted
homes" in large part due to its meticulous construction management process. As
one EVHA judge quipped, the company "could not improve on this process and
still have the subcontractors show up." Judges further describe Ferrier Custom
Homes' marketing practices as a "blueprint for best practices." The company's
marketing materials have a unified look and a strong, central theme, "Building
Dreams. Saving Energy." Its visually striking website hosts detailed
information on past projects including construction photographs, lists of high
performance home features, and testimonials by the homeowners.

GreenCraft Builders' net-zero energy design, including passive solar features
and a whopping 9-kW photovoltaic system, has been producing a utility credit
since the home's occupancy in early 2010. But it's not only the homeowners who
are benefitting. During construction of the home, the jobsite served as a
learning center for other builders and the completed show home was toured
extensively. As the EVHA judges noted, "The outreach effort was exceptional."
In fact, the homeowners still open the house for guests interested in seeing
their uniquely designed and constructed "demonstration" house. The EVHA judges
described the home as an "excellent example of how high performance homes
should be built" with well-thought-out design features and a "balance of
efficiency and cost effectiveness." In short, they said, the project "raises
the bar of what can and should be expected of high performance homes."

Through its marketing efforts that focus on energy efficiency and green
building, production builder Baldwin Homes is educating not only prospective
buyers but also the community at large. In its model home that is open for
tours, cut-aways show "behind-the-wall" energy features and numbered signs
throughout the home correspond to an easily comprehensible tour guide that
explains each green feature. For buyers, the aesthetically-pleasing homeowners'
manual describes the operation and maintenance of high performance homes. Yet,
Baldwin Homes doesn't just talk about efficiency: it built what the judges
describe as a "nice home" in which the "homeowners should be happy with the
performance."

For its winning entry, first-time EVHA applicant Meritage Homes combined
efficiency techniques atypical of a high-volume production builder (Meritage is
the nation's 9th largest home building company) with renewable power
generation. According to the company, the strategy is working: its high
efficiency, solar powered homes are selling three times faster than its
competitors' homes. Meritage Homes is making a big impact on the local new
homes market by constructing 210 homes to the same specifications as the
winning entry—which judges described as having a "great building envelope,"—and
by its strong marketing and educational efforts. The home, say EVHA judges, is
an "excellent example of a builder raising the standard of performance" for

With a self-proclaimed mission that is "as much education as [it is]
construction," Near Zero Maine built a working proof of concept home that, say
EVHA judges, is "well designed and well-insulated." Due to the carefully sealed

house in Maine is only 15,000 Btuh; it is anticipated that the evacuated tube
solar thermal collectors will supply about three-quarters of the annual heating

Implementing a "good team approach with the clients, excellent attention to air
sealing, and extensive motivation and education of subcontractors," led to the
creation of what was described by EVHA judges as a "simple house done well." In
response to the client's need for a second distinct dwelling for a family
member, Scott Homes integrated the additional dwelling unit in the same
structure rather than building two separate structures. This allowed them to
use one heating, electrical, and plumbing system for the entire house and
reduce environmental impact. The judges were impressed by Scott Homes' "deep
community involvement," which includes numerous speaking engagements and
hands-on energy efficiency classes, as well as its focus on energy efficiency
education and outreach in all of its marketing materials and press coverage.
Through active local involvement, Scott Homes is helping to bring energy
efficiency into the forefront in the community.

Green Builder Media, Building Media Inc., and Steven Winter & Associates
This project represents a unique and synergetic partnership between two media
companies and a Building America team to create a net-zero energy remodeled
home while documenting the process of improving an existing home. By
dramatically tightening the building envelope (while leaving the interior wall
surface intact), improving window efficiency, replacing outdated mechanical
equipment, and adding renewable power generation, the partners proved that a
net-zero energy remodel is attainable. Not surprisingly, they garnered
significant media attention for the project, thereby furthering the project's
impact on the remodeling industry.
