  1. Welcome to... Companion PowerPoint Presentation for the Introduction to Housing textbook

  2. Small Homes

  3. 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

  4. 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

  5. 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

  6. Interior-exterior connection roof overhangs porch & deck courtyard Smooth transition from & exterior to interior glass doors lots of windows interior plants

  7. Sustainable Design

  8. 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

  9. LEED-Home Criteria • Location & linkages • Sustainable sites • Water efficiency • Indoor environmental quality • Materials & resources • Energy & atmosphere • Homeowner awareness • Innovation & design process

  10. 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

  11. 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

  12. 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

  13. Energy Efficiency

  14. 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

  15. 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

  16. 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

  17. 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

  18. 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

  19. 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

  20. 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
