On August 16th 2006,
The house received
óóóóó ½
Energy Star rating, the highest
possible, and a NY HERS Score of 92.8 / HERS Index of 36.
This awards winning project is
the contractor’s own house, and his first home. The 3750 square foot house
is overlooking a lake. The home design style is now referred to as
contemporary
craftsman. The original 2500 SF house built in 1983 utilized an octagonal floor
plan. The previous owner referred to it as an “upside-down house”, due to the
bedrooms being located below the main floor. It was clear
from the very beginning that the renovated home would need to have more living
space to accommodate the lifestyle of a family of four. Keeping the same
footprint was the obvious choice, since doing so is more cost effective and
minimized the amount of design by building up rather than out, not to mention
less "red tape".
Additional benefits are a better view of the lake and a much improved curb
appeal.
The house has features that are attractive from many perspectives. The exterior
has all engineered products for durability and low maintenance. Many of
these products came with a lifetime warranty, like the oversize
trim, the
decking
and the railing. The
roofing and the
siding carry 50 years warranties. Absolutely
none of these products requires any paint or stain whatsoever.
The interior of the home has many green features as well. All interior surfaces
are made of basic raw materials: Wood, wrought iron and stone. Raw, but not
"virgin":
Most of the wood were either reclaimed from the original house or from other
buildings. The
reclaimed wood floors for example, are re-milled hickory,
chestnut and pine, each of the 3 levels of the home highlighting one of the three. The
main floor structural supports, and those for the additional level added to
the home, features reclaimed 200 year old Doug Fir and hearth pine beams. Ten of the twelve
existing engineered roof rafters were salvaged
and re-used. The
barn doors, the
dining table,
all the
bath
vanities, a
bed platform, all were custom made from
left-over wood. One vanity was rebuilt from a
discarded armoire found on a
street curb. The walls are finished with
natural earth plaster.
Speaking of walls, we should mention that absolutely none of the
interior walls are load bearing, providing great flexibility in future
alterations to suit changing needs and/or new homeowners. Welcome
universal design.
Central to the home on all three floors is the stone chimney, and the lower and
main level see-through fireplaces. Massive but not overwhelming,
the stone structure rises 48 feet tall. None of the stones needed for the additional 15 foot chimney extension had to be
purchased;
All stones were reclaimed from the existing home, providing a perfect
match. Custom wrought iron structural elements, fasteners, light
fixtures and hardware are used throughout the home, and for the one inch
diameter tension rods holding up the dramatic suspended catwalk to the rafters.
The library rolling ladder, the two pull-down cupola ladders, the hardware for
the
barn doors, all are wrought iron as well. The old exterior spiral staircase was salvaged
and re-used, providing an access between the deck and the patio
below.
The existing home was basically taken down to its foundations; The
only framing that could be retained and left untouched was the lower level floor
joists. Using
advanced framing techniques,
close to 100% of the new home structure is made of
engineered lumber.
This method allows for extra insulation, which is
blown wet sprayed foam for maximum
efficiency and air tightness. Many wall studs from the original home were
salvaged and re-used, some for temporary bracing, concrete forms, blocking, etc.
Most floor joists were put to uses as well, many as planks needed for
scaffolding. All of the exterior
sheathing, as well as the
subfloors, are made of
OSB,
instead of standard plywood. Floor joists, and most of
the roof structure are
TJI’s, also at 24” on center. The sheathing was caulked
before siding was installed, providing a very
tight building envelope.
The exposed eaves and its generous 4’ overhangs, which provides ample shading to
minimize
heat gain during the summer, were built from salvaged lumber originally used for the vaulted ceiling/roof
sheathing and for the
porch roof. All metals was sold to scrap yards for several thousand
dollars.
Looking past the materials, one finds more than just a multitude of
energy saving features. The shape of the structure, the open floor plan, the
high and/or vaulted ceilings, all maximizes the use of natural light and
certainly make the dwellings more spacious than they actually are. A cupola was added with
power windows, not only allowing for extra natural
light, but also for
passive cooling during warm weather, taking advantage of the
natural “stack effect”.
Trellises over the South-facing windows and doors provide shading in summer
months. Another passive cooling feature is the window's manufacturer
factory tinted glass that greatly reduce solar heat gain in the summer and
eliminate harmful UV's
to fabrics; An unexpected benefit is the
resulting privacy. The
thermal mass of the stone fireplace keeps the interior cool during summer and
warm during winter. A 3 ton
high
velocity air conditioning system is all that was required.
Radiant hot
water PEX loops beneath the floors puts heat where it’s needed, under your feet,
and allows the
ultra efficient sealed combustion
gas boiler to run at a much lower
water temperature. An
instantaneous flash water heater provides ample hot water
on demand, without the standby losses of a storage tank.
All of the
appliances are
Energy Star and the lighting is a mix of low wattage
LED’s,
CFL‘s
and some halogen lighting. 24 outside LED spots that lights the entire house use
less electricity combined than one single 75-watt incandescent bulb. Four of the
eight facets of the roof are utilized for
photovoltaic panels generating 6.27Kw
of electricity. Cooling, heating,
cooking, lighting and electrical costs average $3500 for the entire year;
That is less than a dollar per square foot for the whole year!
Even though the existing water well never ran dry in over 25 years, the new
plumbing fixtures, including all four toilets and three shower valves, are low
water consumption, which is less taxing on the septic system.
Last but not least, still one of the most neglected aspect in our industry
today, healthy indoor air quality: Fresh air is maintained in the
home by employing two
heat recovery ventilators. Stale air is picked up from
“wet room” such as the laundry room and the bathrooms and conditioned fresh air
is supplied to bedrooms and other living spaces. Since showers always produce a
large amount of moisture, supplemental ventilation was in order. All three
showers (two of them being totally enclosed since they double as steam showers
as well) received their own in-line unit. A separate, completely independent
whole-house HEPA filter system continually filters out fine particulates such as dust mites,
allergens, etc., with its sole return at the highest point of the house (where
again physic laws “pull” the warmer air) and the sole supply at its lowest, the
lower level, therefore providing a continuous cycle.
Vital "Make up air", to this day still very much not
understood, is provided for each of the fireplaces. In the kitchen area, two automatic
mechanical dampers provide more make-up air absolutely necessary to supply the range hood, which
is equipped with a powerful yet surprisingly quiet 1000 +
CFM
motor. Mounted in the attic rather than inside the hood, this system
is referred to as a remote, in-line exhaust fan. Due to the "attic
being inside", all the AC ductwork is inside the conditioned space, which is
critical to eliminate unhealthy condensation and mold that can form between the
air handler cycles. Because the
air-tight sprayed wet foam insulation
was installed below the roof deck as opposed to the attic floor, it does not
have to fight 130 degrees temperature found in common attics in
the summer months. This makes the whole system remarkably more efficient, also
resulting in longer life for the equipment. One last requisite to healthy indoor
air is a
central vacuum system.
The public demand for such efficient homes in our area is surprisingly still
very low compare to other areas of the country but inevitable. Making the
public and the medias and the public aware of the immeasurable benefits is our
top priority. And for us to experience and live those benefits after
two years of intense work is a pretty good reward in itself, but to be able to
contribute by building more of these gem homes for other conscientious families
is “the ultimate satisfaction”. -
