ORIGINAL PLAN
HE ORIGINAL PLAN PARTI WAS TWO BLOCK CONNECTED BY A LONG NARROW GREAT OOM. IT WAS REDESIGNED SO THE LONG SIDE OF THE GREAT ROOM WAS PERPENDICUAR TO THE SOUTH. THIS REDESIGN ALLOWS THE HOUSE TO GAIN A LOT MORE FROM THE WINTER SUN. ADDITIONALLY THE SOUTHERN WALL WAS CHANGED TO A DOUBLE GLAZED WALL WHILE THE OPPOSITE BECAME A THICK CONCRETE THERMAL MASS WALL THE GLAZED WALL ALSO PROVIDES GREAT DAYLIGHTING FOR THE MAIN SPACES.
REDESIGNED PLAN
REDESIGNED FEATURES: THERMAL MASS WALL WINTER SOLAR GAIN (GLAZED WALL) PERPENDICULAR TO SOUTH DAYLIGHTING
ORIGINAL SECTION
THE SUSTAINABLE GOAL OF THE REDESIGN WAS TO MAKE THE HOUSE COMPLETELY PASSIVELY HEATED AND COOLED. TO ACCOMPLISH THIS A GLAZED WALL WAS PLACED ON THE LONG SOUTH SIDE OF THE HOUSE. THE OPPOSITE WALL AND ADJACENT FLOOR BECAME THICK CONCRETE THERMAL MASS ELEMENTS. IN THE WINTER SOUTHERN LIGHT WOULD BE ABLE TO HEAT THE WALL AND FLOOR MASSES AND THEY WOULD RERADIATE THE HEAT DURING THE NIGHT. THE FLOOR WOULD ALSO HAVE SUPPLEMENTARY RADIANT FLOOR COILS WITH WATER HEATER FROM THE EVACUATED TUBES ON THE ROOF. THE ROOF PITCH WAS INCREASED TO OPTIMIZED THE ANGLE OF THE EVACUATED TUBES AND ALLOW FOR BETTER ANGLE FOR SNOW. SUMMER OPERATION CONSIDERATIONS INCLUDE A LARGER OVERHANG OF THE SOUTHERN GLAZED WALL TO SHADE IT AND AN OPERABLE CLERESTORY WINDOW PROVIDING STACK VENTILATION REMOVING WARM AIR.

THE MODIFIED LANDSCAPING DESIGN CONSIDERS BLOCKING NORTHERN WINDS, AND SHADING S THE PAVED DRIVE. ON THE NORTH SIDE OF THE HOUSE NEW CONIFEROUS TREES ARE TO BE PLANTE CULT TO HEAT IN THE WINTER. ON THE SOUTH SIDE DECIDUOUS TREES ARE TO BE PLANTED THAT WO WALL IN THE SUMMER. IN THE WINTER WHEN THEY LOSE THEIR LEAVES SUNLIGHT WOULD BE ABLE TO HEATED. ONE CONIFEROUS TREE WOULD BE REMOVED ON THE SOUTH EN SIDE SO NOT TO SHADE WOULD BE PLANTED ON THE DOWNHILL SIDE OF THE DRIVEWAY TO REDUCE RUNOFF.

FIBER OPTIC TECHNOLOGY Optical fibers are long thin stands of glass that light is transmitted through. It converts information to light waves which bounce off the walls of a optical fiber. It reflects of the walls of the glass fiber via a phenomena known as total internal reflection. This technology is constantly being improved in terms of cost and materials and is being more widely used to send information over long distances replacing copper and metallic cables.

TOTAL INTERNAL REFLECTIO Li is th va This allows light to bend in a cable as it keeps reflecting off the walls of the tube.

Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire.
e e
Thinner - Optical fibers can be drawn to smaller diameters than copper wire. Higher carrying capacity - Because optical fibers are thinner than copper wires, more fibers can be bundled into a givendiameter cable than copper wires.

c
SINGLE MODE- used for long distances such as telecommunication lines. Lasers can be used as the light source. diameter is 8-10 microns
SINGLE VS MULTI MODE
Less signal degradation - The loss of signal in optical fiber is less than in copper wire. Light signals - Unlike electrical signals in copper wires, light signals from one fiber do not interfere with those of other fibers in the same cable.

HISTORY
ght is sent though a material and bounced off the walls because he outer layer has lesser refractive alue.

Low power - Because signals in optical fibers degrade less, lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires.

Digital signals - Optical fibers are ideally suited for carrying digital information, which is especially useful in computer networks. Non-flammable - Because no electricity is passed through optical fibers, there is no fire hazard. Lightweight - An optical cable weighs less than a comparable copper wire cable. Fiber-optic cables take up less space in the ground.

Sustainable Design Alterations Proposal: 1. Fiber optic day lighting Replace selected electric lamps with fiber optic day lighting lamps to reduce electrical load.
2. Rain water collection Collect Rain water in a drywell to be used to irrigate garden and lawn. To reduce water usage. 3. Insulated Concrete Forms Foundation and cellar walls and the long North wall to be made from ICF’s for better insulation. Provides R-25 insulation and will make the basement warm enough to use in the winter and cool in the summer can save up
insulated concrete forms before
uninsulated foundation causes enitire house to lose energy in cold months INSULATED CONCRETE FORMS CAN BE USED FOR THE FOUNDATION INSTEAD OF CONVENTIONAL CMU OR POURED CONCRETE. THERE IS LESS CONSTRUCTION WASTE AS THERE IS NO WASTED BLOCK OR FORMS. THE INSULATION SERVES AS THE FORM. ADDITIONALLY LAYERS OF INSULATION ARE PROVIDED CREATED A THERMAL BREAK BETWEEN EXTERIOR AND INTERIOR. iT WILL KEEP CELLAR WARM IN WINTER AND COOL IN SUMMER AND SAVE HEATING AND COOLING FOR THE ENITIRE HOUSE .

FIBER OPTIC CABLE COULD RUN FROM THE COLLECTOR TO SPECIAL OPERABLE LIGHT FIXTURES. WHEN THE INSULATED SHADE IS PULLED OVER THE SOLAR GLASS DAYLIGHTING S STILL POSSIBLE. ADDITIONALLY INTERIOR ROOMS SUCH AS BATHROOMS AND THE CELLAR NOW CAN BE PROVIDED WITH DAYLIGHT.

A RAINWATER RECYCING SYSTEM CA BE ECONIMCALLY ADDED TO REDUCE WATER USAGE. THE GUTTER SYSTEM WILL COLLECT RAIN WATER FROM THE ROOF AND TRANDFER IT TO A DRYWELL BURIED BELOW THE FROST LINE. DURING DRY TIMES WATER THE WATER STORED CAN BE USED FOR THE IRRIGATION OF THE LAWN, FLOWER BEDS AND VEGETABLE GARDEN.
