Presentation Transcript

  1. Environmental Controls I/IG Lecture 9 Microclimatic Analysis Microclimatic Design Climatic Factors in Regional Design

  2. Goals Identify and establish the microclimate design determinants

  3. Solar Access – Sun Angles Confirm sun path for solstices and equinox At solar noon: 12/21β=90-23.5-L 3/21 & 9/21 β=90-L 6/21β=90+23.5-L where L=latitude

  4. Solar Access – Sun Path Diagram L: p. 605

  5. Solar Access – Openings/Filters L: p.142, Fig 6.14 Verify solar orientation and obstructions

  6. Solar Access –Solar Envelope Confirm solar envelope of buildings on adjacent and adjoining sites

  7. Wind Conditions – Direction and Speed Obtain climate data

  8. Wind – Channels or Obstructions? Verify distance to openings and barriers

  9. Wind Conditions + Topography Verify changes in terrain Locate changes in local terrain

  10. Vegetation & Soil Conditions –Trees Confirm location and species of trees • Coniferous • Deciduous

  11. Vegetation & Soil Conditions Verify locations and conditions • Vegetation • Surface color • Soil type • Hardscape

  12. Water/Water Runoff Verify water table and drainage patterns

  13. Final Site Summation Compile findings on site diagrams Wind Factors Vegetation, Ground Cover & Drainage

  14. Microclimatic Design

  15. Case Study

  16. Microclimates Interactive Seasonally dynamic Occur outside and inside the building Interactive Fountain, Celebration, FL

  17. Location & Climate Compare site opportunities to the climatic issues L: p. 300 Fig. 11.2c&d

  18. Climatic Design Priorities Assess design priorities “...Region 14 • Allow natural ventilation to both cool and remove excess moisture in the summer.” L: p. 114

  19. Regional Precedents Identify local vernacular precedents Vernacular Side-Gallery House, Charleston, SC

  20. Climatic Form Givers Identify local climatic form-givers

  21. Design Strategies Evaluate design strategies

  22. Contemporary Translation Shutter House for Photographer Tokyo, 2003, Shigeru Ban http://www.shigerubanarchitects.com/SBA_WORKS/SBA_HOUSES/SBA_HOUSES_29/SBA_Houses_29.html

  23. Temperate Cold Hot & Dry Hot & Humid Develop Alternatives Assess and adapt generic models L: p. 333-6, Fig. 11.12 b-e

  24. Develop Alternatives Evaluate possible design solutions within the site context

  25. External Factors Evaluate external impacts for sun, wind, and water

  26. Internal Factors Evaluate internal impacts for sun, wind, and water Atmospheric Research Center, Boulder, CO

  27. Integrate with Building & Site Microclimatescomplement and activate the building design

  28. AIA Climate Zones (1980)

  29. Climate Zone Analysis Each analysis describes: • Climate • Psychrometric profile • Design priorities • Basic conditions • Temperature cycles • Relative humidity • Wind speed • Sunshine • Degree-days
