Rutkin/Teicher Residence

• This type of structure allows for the development
  of non-conical shapes that create stronger
  buildings."
• The shape of the house is formed within Rutkins
  reusable air shell. The form was sprayed on the
  interior with foam insulation. Next, steel
  reinforcements were attached to the interior side
  of the insulation and sprayed with concrete. Once
  the air form is removed the exterior of the
  concrete shell is sprayed with what Rutkin refers
  to as its "protective skin."
• Almost all areas of the house benefit from the
  glass wall. The 45-foot living/dining area
  benefits from the light as does the lofted studio
  reached via the spiral staircase. All three
  lower-level bedrooms of the Rutkin residence are
  enclosed by the glass southern wall. Rutkin and
  his houseguests have more than simply the view
  from their bedroom windows, each room has its own
  door that leads out to the 1,800-square foot
  terrace. Placed on tamped earth, the sprawling
  terrace is constructed of terracotta-colored
  concrete.
• Cross-ventilation became a creative challenge to
  tackle. Due to this section of the house being
  rounded, Rutkin worried that rectangular windows
  could ruin the aesthetic of the shape. Purchasing
  Windows from a ship supply saved 1700 per
  Window

How to achieve

• Develop Baseline energy code model of schematic
  design
• Identify range of isolated energy efficiency
  strategies for all building system categories
• Simulate isolated energy performance
• Identify cost-effectiveness of each isolated
  energy strategy
• Create bundle sets of most promising isolated
  strategies
• Simulate bundled energy performance
• Select final bundle to implement

Structural Insulated Building Panel

• A structural insulated building panel is an
  engineered wood product that consists of two
  outer skins, generally oriented strand board,
  with an inner core of expanded polystyrene.
  Alone, these components are non-structural, until
  they are pressure laminated together under our
  strict quality-controlled conditions using a
  two-part latex construction adhesive.

11
SIP Advantages

• Money - Save labor costs on the installation
  because panels can arrive pre-fabricated. Panels
  save interest on your construction loan by
  consolidating your construction schedule. But the
  most prominent savings are pocketed with energy
  efficiency.
• Comfort - Insulation is an integral part of a SIP
  Home. Air and moisture penetrations are greatly
  reduced because there are so few thermal breaks.
• Quality - Walls are straight, plumb and square.
  The continuous wood surface gives you a sound
  nailbase for any exterior and interior finishes.
• Speed - Framing a 2000 square foot house with SIP
  has been done in a matter of hours. While every
  project may not go that fast, SIP construction
  will shave significant time off the schedule.

IQ Glas

• IQ Glas can serve as either a primary heating
  system or as a supplemental heating system,
  making it an energy-efficient solution for indoor
  swimming pools and sunrooms, office buildings and
  residences. Of course, other features can also be
  incorporated into IQ Glas such as anti-theft,
  alarm systems, soundproofing, and sunblocking. It
  can also be manufactured with built-in blinds
  between the panes and with a feature that turns
  the glass completely opaque with the flip of a
  switch. Each IQ Glas system consists of
  electrical control units (maximum power 23 W/ft²
  or 250 W/m²), the temperature of which can be set
  independently for each room. The electrical
  cables are not visible even when installed in
  older buildings. Although IQ Glas is initially
  more expensive than conventional glass, so many
  possibilities, benefits, and solutions exist that
  the enthusiasm of our clients speaks volumes
  !To sum up, thanks to the similarity of the
  radiant heating of IQ Glas to the sun, room
  temperature settings can be lowered 9F (5 C)
  without any impact on your comfort. IQ Glas is
  maintenance free, sound isolating and filters
  harmful UV light. The air temperature is
  regulated by a programmable clock thermostat, and
  the surface temperature of the glass can be
  regulated by a microprocessor.

Photovoltaic roofing

• Photovoltaics (PV) or solar cells is a
  solid-state, semiconductor-based technology that
  converts light energy directly into electrical
  energy, without moving parts, without noise, and
  without emissions. A Building Integrated
  Photovoltaics (BIPV) system consists of
  integrating photovoltaics modules into the
  building envelope, such as the roof or the
  facade. By simultaneously serving as building
  envelope material and power generator, BIPV
  systems can provide savings in materials and
  electricity costs, reduce use of fossil-fuels and
  emission of ozone depleting gases, and add
  architectural interest to the building.

Waitakere Eco Friendly Home

• The aim Create a family environment friendly to
  nature and sympathetic to the lifestyle of its
  occupants.
• A dual aim was to create a home that appealed to
  the mainstream housing market and which fronted
  onto the road in a welcoming manner.

19
Example Features

• MEP system integration
• The LAW system controls the home's
  electric-related facilities including its
  lighting, heating, security system and some
  appliances. In most homes, these facilities
  operate independent of each other. But in the
  eco-friendly home they interconnect across a
  power cable network by way of a single network
  cable
• LAW system increases the life expectancy of light
  bulbs and tubes.
• HVAC Heat pump
• Unlike conventional heaters, the power isn't
  converted into heat, it is only used to power the
  pump that circulates the liquid through the
  system. The same principal is at work in your
  refrigerator. The heat pump in your fridge
  extracts the warmth from inside the fridge and
  releases it outside which is why the back of your
  fridge is warm. And it continues to work even
  when the inside is colder than the outside.
• Cost effective package
• Less harmful to the environment. It doesn't
  produce any carbon dioxide emissions that
  contribute to global warming. Carbon dioxide and
  other gas and water vapour emissions are often
  regarded as a major drawback of solid fuel and
  gas

20
Example Features

• Induction Stove
• Breathable walls
• The plaster used breathes and allows water vapour
  to move through it. This stops trapped moisture
  impacting on other building materials which can
  deteriorate. At the same time, the plaster and
  water repellent stops outside water getting into
  the home
• Woolblend insulation
• Sheep wool, recycled carpet wool and regenerated
  polyester were used to make 'Thermowool'
  insulation
• Drainage
• A Polyethylene Drainage System is a waste
  bi-product from the oil industry and no toxins
  are emitted during this production process. It is
  also fully recyclable.
