Presentation Transcript
orientation
Orientation
  • Building should be positioned to maximize desirable features and minimize negative aspects
    • Energy Orientation
    • Solar Orientation
    • Room/Outdoor Area Locations
    • Overhang and Baffle Protection
    • Land/Shelter
    • Wind Control
energy orientation
Energy Orientation
  • Local resources and climate have an affect on energy use – heating, cooling, and lighting
    • Native Americans building houses under the overhang of cliffs
      • Provided shade from the summer sun and protection from winter wind
energy orientation1
Energy Orientation
  • Fossil fuels are finite so energy efficient principles need to be used
    • Combustion of natural materials such as reclaimed wasted, wood or other organic materials
    • Require special equipment to heat/cool the home
solar designs
Solar designs
  • Active solar designs – Use of mechanical/electrical tools or devices to control the sun’s energy
  • Passive solar designs – Use of the sun’s power without mechanical/electrical tools or devices. Use design features and orientation of a building to gain control of the sun’s energy
solar orientation
Solar Orientation
  • Sunlight angle changes from summer to winter as the earth revolves around the sun
    • Northern Hemisphere: South and West sides of a structure are warmer than the North and East sides, South being the warmest
      • Building should absorb southern heat in the winter and repel in the summer, also plan to provide natural sunlight
floor plans
Floor plans
  • Open floor plans and tall ceilings create cooler temperatures and

increased ventilation

  • Closed floor plans and low

ceilings typically increase

temperatures

room layout
Room layout
  • The function of the room as well as the season/time of day the room will be used should be considered when the layout is determined
  • Typically the dining room and kitchen should get sunlight early in the morning and then the living room should have light by afternoon
room layout1
Room layout
  • Kitchen and dining room on the south or east side of the house
  • Living room areas are placed on the south or west, receive late day rays of the sun
  • Sleeping area tends to be located on the North side of the building, provides greatest darkness in morning/evening and is also the coolest side
overhangs baffles shields
Overhangs/baffles(shields)
  • Thought out to allow the max amount of sunlight and heat to enter the inside of a building during winter, opposite for summer
  • Edge of the overhang should be related to the height of the window
baffling and louvers
Baffling and Louvers
  • Should be

accomplished

without

blocking

natural

light

Not all light can be blocked

    • Direct and indirect radiation through windows
