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

pane glass?

• 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

board insulation

• 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

Conversely, Kasprzak-built

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.

Environmentally Friendly

Cellulose Insulation

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

Fluorescent Lamps

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

Heat Exchanger

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

hot water.

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

northern climates.

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

Certification Corporation,

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.)

We constantly keep abreast of government

incentive programs looking for the best deal

Glossary of Terms

To help better understand the different

construction, heating and solar energy terms

in this brochure, here is a brief guide to their


Boiler is a closed vessel in which water or other

fluid is heated. The heated or vaporized fluid

exits the boiler for use in various processes or

heating applications.

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.

CFL is energy efficient compact fluorescent lamp

which uses a quarter as much electricity as a

regular bulb and lasts several times longer.

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

conductive materials.

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
