Companion PowerPoint Presentation for the Introduction to Housing textbook



  • What is a small home?

    1,200 to 1,700 square feet

  • Advantages for young families buying their first home, busy career persons, or mature adults wanting to downsize

  • Require less cleaning, painting & routine maintenance

  • More easily negotiated & higher energy efficiency

  • Require fewer resources to build


  • Mies van der Rohe—”less is more”

  • Question—How do you either create or recreate qualitative space which is limited in square footage (reality) but looks larger than it actually is (illusion)?

  • Do it through craftsmanship (best that can be afforded), materials (high quality) & design

  • Hans Hollein (Pritzker Prize winner)—combines the costly with everyday materials



  • Interior-exterior connection be more extensive & desirable that what actually exists

    roof overhangs

    porch & deck

    courtyard

    Smooth transition from & exterior to interior

    glass doors

    lots of windows

    interior plants


Sustainable design
Sustainable Design be more extensive & desirable that what actually exists



Leed home criteria
LEED-Home Criteria of the present without compromising the ability of future generations to meet their own needs

  • Location & linkages

  • Sustainable sites

  • Water efficiency

  • Indoor environmental quality

  • Materials & resources

  • Energy & atmosphere

  • Homeowner awareness

  • Innovation & design process



  • Holistic approach that includes: harmony with their surroundings

    solar orientation

    daylighting

    healthy ventilation systems (IAQ)

    environmentally friendly components such as recycled materials

    energy efficiency

    Rug made from

    recycled plastic

    Bamboo floor


Strategies harmony with their surroundings

  • Interior design—taking advantage of natural sunlight for lighting; minimizing interior space

  • Architecture envelope—adopting climate responsive design

  • Culture—designing to reflect local culture

  • Siting—acknowledging interrelationships between humans & their environment

  • Alternative building materials—selecting local and/or resource efficient materials

  • Energy efficiency


Energy efficiency
Energy Efficiency harmony with their surroundings


Why focus on housing
Why focus on housing? harmony with their surroundings

  • Accounts for a major portion of total energy use (20%)

  • Heating (38%) is largest consumer in home

  • Easiest sector to target

  • A great deal (perhaps 50%) of energy is wasted

  • Most homes are not adequately built for energy efficiency & older homes are typically not efficient

  • High energy prices can create financial burdens for homeowners and renters


  • Energy programs: harmony with their surroundings

    Built Green (Colorado)

    Energy Star (U.S. Environmental Protection Agency)

  • Many minor modifications can enhance energy efficiency (including appropriate R-level & site plan)

    Compact fluorescent

    lights

    Efficient ceiling

    fan


Earth-sheltered housing harmony with their surroundings

  • Uses the earth as a barrier & as a moderator of temperature

  • Not a new idea

    sod homes

    earth berming

    homes built into hills


Geodesic dome harmony with their surroundings

Uses 30% less surface area to enclose the same amount of volume as a box type structure—less area for heat to escape or outside air to penetrate

Spherical shape provides for natural and efficient interior air circulation


Solar housing harmony with their surroundings

  • Active—uses collectors, pumps, & tanks to collect & distribute the sun’s heat

  • Passive—where the shell of the house & living space collect & distribute the sun’s heat

  • Photovoltaic cells—convert sunlight directly into electricity


Components of a passive solar house: harmony with their surroundings

  • Direct gain—sunshine enters south-facing windows; absorbed within living space; stored in mass within home

  • Indirect gain—energy from sun collected at one place, such as a solar greenhouse


Wind-powered housing harmony with their surroundings

  • Wind power is the world’s fastest growing energy source

  • US wind turbines produce over 3 billion kilowatt hours of electricity

  • Wind turbine generators harness the energy of moving air to generate electrical power
