Companion PowerPoint Presentation for the Introduction to Housing textbook


Welcome to

Small Homes


Welcome to

  • 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


Welcome to

  • 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


Welcome to

  • Key is to create illusionary space—space which appears to be more extensive & desirable that what actually exists

  • Some possibilities:

    glass & skylights

    mirrors

    curves

    wall-to-wall floor coverings

    multi-purpose, small scale furnishings


Welcome to

  • Interior-exterior connection

    roof overhangs

    porch & deck

    courtyard

    Smooth transition from & exterior to interior

    glass doors

    lots of windows

    interior plants


Sustainable design

Sustainable Design


Welcome to

  • Sustainable design is defined as design that meets the needs of the present without compromising the ability of future generations to meet their own needs

  • The U.S. Green Building Council’s Leadership in Energy and

    Environmental Design

    (LEED) Program


Leed home criteria

LEED-Home Criteria

  • Location & linkages

  • Sustainable sites

  • Water efficiency

  • Indoor environmental quality

  • Materials & resources

  • Energy & atmosphere

  • Homeowner awareness

  • Innovation & design process


Welcome to

  • Frank Lloyd Wright—houses should grow from and work in harmony with their surroundings

  • Emerging goal is to create environmentally conscious homes that remain functional & aesthetically pleasing


Welcome to

  • Holistic approach that includes:

    solar orientation

    daylighting

    healthy ventilation systems (IAQ)

    environmentally friendly components such as recycled materials

    energy efficiency

    Rug made from

    recycled plastic

    Bamboo floor


Welcome to

Strategies

  • 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


Why focus on housing

Why focus on housing?

  • 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


Welcome to

  • Energy programs:

    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


Welcome to

Earth-sheltered housing

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

  • Not a new idea

    sod homes

    earth berming

    homes built into hills


Welcome to

Geodesic dome

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


Welcome to

Solar housing

  • 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


Welcome to

Components of a passive solar house:

  • 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


Welcome to

Wind-powered housing

  • 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
