Hybrid Energy Saving
Taking a Closer Look
Walking around any home, it’s almost
impossible to tell what energy saving features
the building offers. Most are hard to see by a
simple visual inspection.
• Are the walls and roofs well insulated,
producing a high R-value?
• Are the windows double or triple thermo
• Is the heating system efficient and cost
• Is there an exterior wall thermal barrier?
Answers to these and other related questions
helps determine just how energy efficient
any home really can be.
Energy efficiency and performance is what
Hybrid Energy Saving Construction is all
about. For our company, this means the
application of state-of-the-art architectural
design and building techniques, combined
with the careful selection of premium
components, including insulation, windows,
heating systems and alternative hot water
solar energy systems. For the owner,
combined, these elements deliver energy
saving performance and benefits… now
and for the future.
Building Energy Efficient
Homes Since 1973
As a family company, started over 40 years
ago, Kasprzak has built more residential
homes and condominiums in Maine than
any other company. For quality, energy
savings and reliability, Kasprzak designed
and built homes have always outpaced the
Today, we reaffirm our commitment to energy
efficiency and performance no matter the size
or configuration of the homes we build. For
example, a Kasprzak condominium with an
average of 1,900 square feet of living space
typically requires only 600 to 700 gallons of
fuel oil annually for the combined baseboard
heat and domestic hot water. Now, we offer
more options that can help reduce oil and
electric consumption even further.
Key reasons why our condos are more energy
efficient than the competition:
• Exterior, thermal barrier walls with energy
• High Efficiency rated Viessmann boilers
• High Efficiency rated, triple glazed
Hybrid windows by Paradigm
• Optional Viessmann Solar Collector for
domestic hot water
• Energy Star ® Rated Appliances
Exterior Thermal Barrier Walls
Thirty years ago, Maine’s building code
standards for exterior wall insulation
increased from R-13 (3½ inches of fiberglass)
to R-19 (6 inches of fiberglass). At that time,
most homebuilders switched from 2 x 4 wall
construction to 2 x 6 wall construction to
accommodate the 6-inches of insulation.

Dark areas indicate heat loss and cool temperatures.
This meant everywhere there was wood
framing in the wall, there was no insulation
between the cold outside air and the heated
interior space. This solid wood area in a 2 x 6
framed wall typically represents 20% of the
wall area, and has only a R-7.5 value across
these wood members as compared to R-19
for the 6 inches of fiberglass.

Note: R-Values are per manufacturers’ product specifications
homes at that time, met the
new code requirement of R-19
with 1-inch thick energy board
insulation, (R-6) and 3½ inches
of fiberglass (R-13) between
the 2 x 4 studs for a total
R-value of 19. One inch thick
energy board has an aluminum
foil face and is taped at all of
the joints, creating a thermal
barrier across all of the wood
framing in the exterior walls.
The infrared photographs below
demonstrate energy loss and
shows how effective the thermal
barrier is in minimizing heat loss.
Triple Glazed Hybrid
We specify the multiple-glazed Paradigm
Hybrid window made here in Maine.
These premium windows offer a ¾ inch
triple glazing with two Low-E coatings as
well as Krypton gas. This window offers
a value of R-5.6; almost double the
R-value of its competitors.
We believe that this engineered window
supplies significant energy savings
compared to windows with much lower

Blown-in R-52 cellulose insulation material in a
condo attic area.
We use blown-in cellulose insulation to a
depth of 14 inches (R-52) in all the areas
with flat ceilings. It is a natural wood product,
and 75% of what it’s made from is recycled
newspaper and fire-retardant additives
which gives the material a Class-1 fire rating,
making it an extremely safe product.
One of the biggest advantages of using
cellulose is its performance value. Because
of its tighter density, it has a higher R-rating
per inch of material and outperforms many
common insulation products such as fiberglass.
Its loose nature makes it easier to install into
irregular space areas, creating a custom-fit,
monolithic seal over an entire area.
From both health and environmental
perspectives, cellulose is considered a
“green” product and ecologically very sound.
It contains no formaldehyde, and cancer
warnings are not required on the labeling.
Energy Efficient Compact
In 2007, we replaced all the incandescent light
bulbs in our condos (except for those used
in recessed lighting), with energy efficient
compact fluorescent lamps, commonly called
CFLs. The advantage of this type of lamp is
that it uses about a quarter as much electricity
as regular bulbs and lasts several times longer.
Lighting makes up approximately 40% of
the average electrical energy use in a typical
Maine home (see for yourself with Central
Maine Power’s Home Energy Calculator at
If you have a monthly electric bill of $100
then $40 of that bill is for lighting. Using CFLs
lowers the monthly part of your lighting bill to
approximately $10, a savings of $30 a month,
or $360 for the year.
The Oil Fired Viessmann
Boiler With Triple Pass
In the early 1970’s, popular inexpensive
baseboard electric heat and electric hot
water heaters were the standard in the
industry. They were replaced with oil-fired
boilers with single-pass heat exchangers
for hot water baseboard heat. These
boilers have a coil in the boiler to heat
the domestic hot water.
These furnaces operate 24 hours a day,
year round, and boiler water temperature
cycles between 180° to 200°F since the
hot water in the boiler is used to heat the
domestic hot water. Even in the summer
time, the furnace continues to fire up
every time the water in the boiler drops to
180°F; even if you’re away on vacation,
and there is no demand for any domestic
We began specifying European designed
and engineered Viessmann boilers with a
triple pass heat exchanger in 2005 as our
standard heating unit. The triple pass heat
exchanger increases the efficiency of the
boiler and means less heat is going up the
chimney. Older furnaces with single pass
heat exchangers have a typical chimney
flue temperature of 500° to 600°F.
Boilers with a triple pass heat exchanger
have a typical flue temperature of 350°.
Super Store Contender
Indirect Hot Water Tank
In concert with the Viessmann boiler, we
specify the Super Store Contender indirect hot
water tank. This tank has a 2-inch thick R-17
foam insulation and allows less than ½ ° F of
heat loss per hour from the storage tank.
The water in the storage tank cycles between
120° and 140°, and if no domestic hot
water is being called for, it could be as long
as 40 hours before the furnace is needed to
heat the domestic hot water. As a result, the
homeowner will find a significant savings in
annual fuel oil usage.

Option: Viessmann Vitosol
Solar Collector – Free Hot
We offer an option to add a Viessmann solar
collector to heat your domestic hot water. This
should save 175 to 250 gallons of oil per
year, depending on family size and lifestyle.
A Vitosol 300 system should replace up to
70% or more of the energy required to heat
domestic hot water. This highly effective
collector system is specifically designed for
In the summer months, this high performance
system will cover almost all the energy
required for the domestic hot water, thus
reducing oil and electrical
consumption and thereby
making the homeowner less
dependent on fossil fuels.
Using the highest quality
corrosion and UV-resistant
materials, Vitosol collectors
are performance tested in
Europe and North America
by the Solar Rating and
and are designed to
produce a consistently high
thermal output for more
than 20 years.
For a typical family of two, a single 3½
x 8 foot flat plate, or a single 5 x 6 foot
20 tube solar array is all that would be
required. We estimate annual oil usage for
domestic hot water for a family of two in
our condominiums to be 250 gallons to 325
gallons. These solar tubes have an average
annual efficiency of 70% or more, offering
an estimated savings of 175 to 225 gallons
of oil per year. For example, if oil is $4.00 a
gallon, this represents an annual savings of
$700 - $900 a year.
(The state of Maine conservatively estimated
in its 2007 Annual Report for Maine Solar
Energy Rebate Program an average savings
of 180 gallons for various solar systems
installed in the state.)

Cellulose Insulation is a non-conducting
material used to separate the internal climate
and sounds of a building from external climate
and sounds, made with recycled newspaper
using grinding and dust removing machines and
adding a fire retardant. Cellulose has the highest
recycled content of any insulation material and
also has less embodied energy than fiberglass
and other furnace produced mineral insulations.

Chimney Flue is a masonry duct for conveying
exhaust gases from a fireplace, furnace, water
heater, or boiler, to the outdoors.
Energy Board Insulation is a glass-fiberreinforced
polyisocyanurate foam core with solid
aluminum foil facers on both sides.
Energy Star® is a US Government program
to promote energy efficient consumer products.
The program was created in 1992 by the United
States Environmental Protection Agency to reduce
energy consumption and greenhouse gas emission
by power plants. The program was intended to be
part of a series of voluntary programs, that would
demonstrate the potential for profit in reducing
greenhouse gases and facilitate further steps to
reducing global warming gases.
Fiberglass Insulation (also called fiberglass)
is material made from extremely fine fibers of
glass, and this material when combined into batts
is used to reduce the rate of heat transfer. All
insulating products are based on a single basic
principle: heat moves from warmer to colder
areas. On cold days, warm air from inside tries
to get out. On warm days, the hot air outside is
trying to get in. Insulation slows this process.
Indirect Water Storage Tank is a tank used
for storage of domestic hot water, separate
from the heating system boiler, without interior
electrified heating elements to heat the water in
the storage vessel.
Knee Wall is generally any short wall, usually
3 to 5-feet in height and used as a part of the
support for a roof structure and found in an
attic or loft. Low walls are also used in offices
and other rooms to separate an area for storage
or for aesthetic reasons. A short wall is used in
construction of the second floor of a one-andone-half-story
Low-E (low-emissivity) glass has a thin
metal coating on the glass within its airspace that
reflects thermal radiation back into the interior
and allows solar radiation into the room. Thus,
the coating helps to reduce heat loss but allows
the room to be warmed by any sunshine. The
principle of operation is similar to the greenhouse
effect where short wavelength radiation is
transmitted through the pane, but longer
wavelength radiation is reflected.
R-Value is the measure of resistance to heat
flow. Insulation materials have tiny pockets of
trapped air, these pockets resist the transfer of
heat through material. The ability of insulation
to slow the transfer of heat is measured in Rvalues.
The higher the R-value, the better the
insulation material’s ability to resist the flow of
heat through it.
Single Pass Heat Exchanger is a device built
for efficient heat transfer from one fluid or gas
to another, whether the fluids are separated by
a solid wall so that they never mix, typically a
plate heat exchanger composed of multiple, thin,
slightly-separated plates that have very large
surface areas and fluid flow passages for heat
Solar Energy is energy from the sun. Solar
energy predominantly arrives in the form of
infrared, visible and ultraviolet light, and is either
returned back to space or is absorbed. Nearly
all of the absorbed energy is converted directly
to heat, with a small but important fraction
converted to chemical energy, such as in ozone
production, photosynthesis or photovoltaic energy
Kasprzak Homes, Inc.
Solar Thermal Collector is a solar collector
specifically designed to collect heat that absorbs
sunlight in order to provide heat to generate
solar hot water. Collectors have multiple
evacuated (vacuum space) glass tubes which heat
up solar absorbers and solar working fluid (water
or an antifreeze mix) in order to heat domestic
hot water. The evacuated tubes minimize the reradiation
of infrared energy from the collectors,
allowing them to reach considerably higher
temperatures than most flat-plate collectors.
A further advantage this design has over the
flat-plate type is that the constant profile of the
round tube means that the collector is always
perpendicular to the sun’s rays and therefore the
energy absorbed is approximately constant over
the course of a day.
Thermal Barrier (break) is an element of low
heat conductivity placed in an assembly to reduce
or prevent the flow of heat between highly
Thermal Bridge is a point in the building
envelope that allows heat conduction to occur.
Since heat flows through the path of least
resistance, thermal bridges can contribute to
poor energy performance. A thermal bridge is
created when materials that are poor insulators
come in contact, allowing heat to flow through
the path created. Insulation around a bridge
is of little help in preventing heat loss or gain
due to thermal bridging; the bridging has to be
eliminated, rebuilt with a reduced cross-section
or with materials that have better insulating
properties, or with an additional insulating
component (a thermal break).
Triple Thermo Pane Glass is a set of three
lites of glass spaced apart and hermetically
sealed to form a single glazed unit with an air
space between each lite. The space between the
lites may be filled with air or an inert gas like
argon or krypton which provide better insulating
