Important Features of a Full Solar
Home
How many times have you heard that your home is
your biggest investment? For most people, it’s true.
And as you see from our interactive calculator, a
Full Solar Home is the best investment by far
Since you plan to live in the future, it’s wise not to
choose a home designed for the past.
Here are a few features that will contribute to your
comfort, safety, and enjoyment in the future.
Climate Control for a changing climate
This starts with a sealed attic (see the Design
page) and proper insulation, including double-
glazed insulated windows (impact-rated in some
areas). This makes it easy and energy-efficient to
maintain pleasant temperatures and humidity in
your home over a wide range of conditions in the
outside world.
With a modern HVAC system, outside air entering
the home can be microfiltered against particulates
and allergens, UV-sterilized, and
humidified/dehumidified as well as temperature-
controlled. Modern systems with inverter drive
compressors and variable speed fans maintain
temperatures more precisely — and much more
quietly — than the typical system that waits until
you are too warm or cold before it whooshes on for
a while.
A range hood that vents to outdoors
No explanation needed, but not all of them do that.
A heat pump waterheater is three times as effi-
cient as a typical electric waterheater.
The modest cost difference is no excuse for not
having one.
Metal-clad wiring
Codes and customs vary by jurisdiction. In some
places, you need hard steel conduit for your wiring,
and in others you can use Romex or even individual
conductors. Metal-clad is accepted in most
jurisdictions, a group of wires inside a flexible
gooseneck tube of aluminum or galvanized steel,
called armored, metal-clad or MC. Steel MC reduces
EMI (electromagnetic interference) by 95%, and
many claim they sleep better in homes with MC
wiring.
From our perspective, the cost of MC is close to the
cost of the separate wires inside, and can save you
a lot of time (money) on wiring. With a proper plan
(hint!) precut and labeled lengths can make wiring
the home easy, saving not only wiring time but
time wasted waiting for electricians.
MC connects to boxes with simple fittings. MC
comes in all combinations of wire gauge and
numbers of solid or stranded conductors needed
for any home.
Roof decking material (and exterior sheath for
frame construction)
Don’t accept plywood or OSB for the roof. These
materials are commonly used because they are
cheap and theoretically good enough. In real life
they often get wet before the roofing is installed.
They are subject to rot and mold.
PEX plumbing
Cross-linked polyethylene tubes, known as PEX (or
XPE or XLPE) have been standard in Europe for 40
years and are increasingly popular in the U.S. We
recommend PEX because it is fast and easy to
install, and eliminates couplings and joints
(potential leaks) in your attic and walls.
With a manifold as shown you can to turn off the
water to any tube, and use a continuous length
from the manifold to each fixture. Again, with a
proper plan, precut and labeled lengths save even
more time on installation. PEX-type tubes use
simple fittings that attach fast and reliably. More
economical than copper, more reliable and easier
than rigid PVC plumbing (and overall cheaper), you
can save even more time in construction not
waiting around for plumbers.
And what about some fun? A media wall.
It is amazing how many homes, new and old, don’t
have a simple 12-foot wide wall in any living area.
100-inch flatscreens are awesome, but where can
you put it?
You can also get a small 4K projector that can hang
from the ceiling or sit under your coffee table and
fill a 12-foot or wider wall with movies, sports or
whatever you like, at surprisingly reasonable
prices. This is a stunning new dimension in home
entertainment, yet most homes can’t take
advantage of it.
Contrary to popular belief, you don’t need a
projection screen. Any white-ish or light colored
wall with flat interior paint will do. When you turn
off the video, it’s just a wall. Turn it on and it’s a
whole new world.
Hey, it’s the future, right?
Pay a little extra for a product like ZIP board from
Huber huberwood.com which is much stronger
than plywood and so impervious it is guaranteed
for 6 months directly in weather. Panel joints are
sealed with Zip System tape or Zip liquid flashing.
With Zip board’s built-in water-resistant barrier and
air barrier, many exterior claddings don’t need
housewrap.
