Passive Solar log and timber homes built with Sustainable Heating solutions.
Integrating inexpensive heating and cooling design into your home.
Passive solar / Direct gain /Passive solar designed homes.
You have noticed the heat that can build up in your car on a sunny day,
even in winter, that is solar gain.
Why not capture that heat in your home, but only in the winter,
through passive solar design?
Notice how cool shaded concrete is even on a hot summer day,
that is thermal cooling storage!
These are the simple concepts behind passive solar heating and passive
geocooling that save on energy costs, make your home more comfortable,
and are very inexpensive to incorporate into your home design.
Passive systems have no moving parts, are environmentally sustainable,
they can provide tax credits, and are no more expense in the construction process,
how about lower utility bills with cost saving comfort, It is really that easy!
Think of it this way, all homes are passive solar, but most are very
inefficient and in some cases they will help you loose your heat far faster than you think.
lets think about some possibilities to make your home work better for you.
When building a log home, most people plan to own and live in them
for an extended period of time. Their log home may be a family retreat
or a retirement home that they intend to own for the rest of their lives.
Now how many times do you have to design it with solar benifits, Only once!
The turnover rate of log homes is much lower than the average
conventionally built house.
Let's look at the common sunroom as an addition for starters.
Design and function are most efficient when the room faces directly south and has
a lot of glass windows & doors.
Dark stained concrete floors and tile absorbs more heat than liter colors.
Deciduous trees around the sunroom allow warming sunlight to get through
when the leaves are gone in the winter.
In the summer, the eves provide shade and assist in the geocooling cycle.
With such a long term outlook, the decision to build green and live in a
energy efficient home is smart.
Passive solar or direct gain design combine with a well insulated structure makes
good sense for the health of the environment and a families future, green built homes.
The earth is heating up, why not capture heat that is already here!
We are proud to construct our green built log homes with reclamed forest products.
Our exterior and structural timbers are from reclaimed “dead stand” trees.
These damaged forest areas have perished due to fire, or by other natural causes.
In our northern hemisphere, the sun is lower on the southern horizon in
the winter and higher above in the summer.
In California, Nevada, Utah and Rocky mountains, for example,
a two-foot eves on the southern side of your log home will shade the floor the in summer .
Sun radiate warmth through the southern glass windows
and doors warming the floor during the winter months.
Providing the floor has thermal mass and is dark color,
will absorb and store heat from the winter sun.
The concrete slab should be insulated from the earth , to store heat most efficently.
In the summer, the shaded 55-degree ground temperature will help keep your home cool.
This solarium for example performs very well summer and winter,
by utilizing a lexan, polycarbonate insulated roof system,
with retractable shade cloths to deflect the summer sun.
Opening sliding doors lets a breeze through keeps it cool in summer.
During winter months, the solar energy stored in the concrete
slab helps keeps the interior warm at night.
In winter, on sunny days where the temps do not rise above 20 degrees,
this solarium heats up by an average of 50 Degrees warmer inside temps.
So that one can enjoy temps of 75 to 80 degrees inside all winter!
This heat is used to warm the rest of my home in afternoon by circulating the air.
Temp controled fans turn on and blow the warm air in to the main living area.
Yes we love passive solar heating!
Direct Gain / Passive solar.
Passive solar referes to design and material choices that capture and or deflect the sun's heat.
To promote thermal comfort and energy conservation you reduce the need for, fossle fule burning
mechanical heating, cooling, and ventilation systems.
This is a traditional method used throughout the world to cost effectively increase comfort.
Passive Solar Heating does not require solar panels.
The primary elements required are south facing glass and a
thermal mass to absorb, store, and distribute heat.
The easiest and least expensive approach to solar is a passive system direct gain.
The goal of all passive solar heating systems is to capture the winter sun' heat
within the building and release that heat during periods when the sun is not shining.
In this direct gain system, the actual living space of your house
becomes a solar collector where heat is absorbed and distributed
through a simple system.
South-facing glass admits solar energy into the house where it directly
and indirectly strikes thermal mass materials, such as masonry floors, a stone hearth,
Rammed Earth walls & fireplace and walls.
These Rammed earth walls are 18" thick providing a large thermal mass.
The direct gain system utilizes 60 - 75 percent of the sun's
energy striking the windows.
With our Log Homes we offer gable and eve window feature walls that
help provide this solar gain potential! In addition, our gable-end overhangs
extend out 4 feet as a standard to offer shade from the summer heat.
Advantages from building with pre-built 1/2 log homes system;
Our logs are carefully selected to contain less than 19% moisture content -
the most significant cause of cracking and warping.
Sealed Tight From the Elements
High quality chinking between the log siding, conventional R24+ blown insulation,
and an interior vapor barrier ensure that only invited guests make it into your
We employ highly skilled craftsmen at reasonable labor rates.
Lumber costs tend to be much more stable where where we run our
sustainable timber harvest program.

Passive solar design & Building Green makes sense!
Passive solar construction is built into the design.
Why not design a smarter way to live into your new home?
Norm Clover, a Northern California, Utah, Nevada Log Home Dealer/
energy efficient building developer and Contractor, has extensive
experience building a variety of solar energy efficient and environmentally
friendly green homes including:
Rammed Earth homes in Sonoma County's wine country; Straw Bale homes;
and SIP Panel high insulated passive solar homes. We have been incorporating
passive solar into all of these home designs.
Below is an example of a SIP Panel passive solar assisted
home in Park city Utah .
This home gains 6 to 10 degrees daily on sunny days with outside temps never above freezing.
The night heat loss is less than 1 degree / hour.
This home was designed and built by Grizzly Log Builders.
The siding on this home is Hardie Board, fire resistant material.
Grizzlylogbuilders is now offering this material as an alternitive
to the exterior 1/2 log and 12"timber siding for all models.

How many times are you going to build your get away cabin or familys gathering place?
With energy costs on the rise and no end is sight, it makes good
economic sense to design passive solar and build with efficiency in mind.
There is a great deal of documented evidence supporting the energy
efficiency related to the construction of panelized prebuilt and
insulated log homes.
