Description
of Project
In
September of 2004 we purchased a 35 acre lot south
of Fairplay, Colorado as the first step in my
dream of both building an off-the-grid solar home
and designing/building a home. I was inspired by
attending the Denver and Boulder Tour of Solar
Homes for many years. The land is on the east side
of the Continental Divide and consequently gets
less snow than the western slope but can get lots
of snow with huge drifts. It is very high (9600
feet). After looking at a lot of land in Colorado,
it was one of the only properties that had a nice
southern mountain view, the southern orientation
being very important for the passive solar aspect
of the house. The area has excellent hiking,
running, fishing, and mountain biking opportunities as well
as being relatively close to some cross-country
skiing and about 45 minutes from Breckenridge ski
area. We purchased a camper as a construction
dwelling.
We
did not plan on starting the building so soon but
my daughter and I went to meet with a builder of
tilt-up concrete passive solar homes outside of
Pueblo Colorado and were at that time favorably
impressed, deciding to start building when the
ground thawed in early June, 2005. I took two
online classes from Solar Energy International
on "Solar Home Design" and "Photovoltaic Design
and Installation."
The
home has many energy efficient features including
passive solar design, insulated concrete
construction, concrete exterior walls and most of
the interior walls to serve as thermal mass,
energy efficient exterior and garage doors,
energy-efficient/Energy Star appliances, 5.6 kW
photovoltaic system with battery storage (
Solar-One HUP Batteries 48V 845 aH 40
kwH since 2018) for electric requirements, solar hot
water (380 gallon storage tank and 200 sq feet of
collector panels) with backup propane fueled Takagi on-demand hot
water heaters for domestic hot water and space
heating with radiant infloor heat, a Tulikivi masonry
fireplace for supplemental heating, structural
insulated panels (SIPs) R-42 for roof, extremely
energy-efficient "Heat Mirror" windows,
daylighting with clerestory windows, and a heat
recovery ventilation system. Since the home is
very tight, without too much ventilation, healthy
building materials, paints and sealants have been
used. The cabinets are made of lyptus which is a
renewable wood. The house is stucco with brown
window trim and a brown roof. The space above the
garage is used for exercise equipment and a table
tennis table. We currently have satellite internet
service which allows for VOIP for phone
service. Cellular service and a landline are not
available.
The
building process went very poorly and took longer
than the estimated finish date of March, 2006. We
had problems not only with the builder and almost
all of the subcontractors but also the remote
location, the lack of familiarity of the
subcontractors with green building practices, and
the harsh weather conditions which made things
extremely difficult. While my builder had some
very good ideas about passive solar design, it
turns out that she was a poor general contractor.
The result was that I did much of the general
contractor work and all of the bill paying. Most
but not all of the problems have been correctable
for a price. We did the minimum required for a
certificate of occupancy, and miraculously
obtained one in December, 2006.
I
slowly did as much of the finish work as I
could, and eventually finished. Since this was my dream solar home, the building process was
very stressful. On the positive side, my husband
was amazingly supportive. He actually has
been impressed with the outcome and is not second
guessing my bad decisions. He only has pointed out
that the project was far too ambitious and that
the house should probably have been a lot smaller (I agree).
My daughter liked the house and helped me do some
of the work. My son didn't like all the time that
I spent in Fairplay, but was helpful cutting
firewood and admitted that he would have been
disappointed if I had given up.
