www.arkleg.state.ar.us/data/SustainDesignBuildingPractice/GreenBldgInit_files/frame.htm#slide0235.htm Site Analysis is the process of surveying or studying the existing environment and how it will influence the structure’s design and layout on the site.
Now you know why I asked you to purchase some basic colored markers and colored pencils for the Ach 111 class ! Site Analysis and Site Plans (rendered)

The Angle of the Sun varies during the seasons, this is due to the tilting of the earth’s axis as it rotates around the sun. Actually, the earth is closer to the sun in winter but the northern hemisphere is tilting away from the sun.
Therefore…. one could assume that a design that works well for a flat plot of land may not do as well for a sloped topography and visa versa. http://www.cce.ufl.edu/current/green_building/passive.html
The Affects of a Slope
Affects of Slope on Building Design
Therefore a SITE ANALYSIS must be completed first before design development can commence.
Exterior devices are better than interior devices, because they intercept the sun’s radiation before it can reach the surfaces of the building.
Relationship between 2-D and 3-D representation of site topography (contour lines)
Contour lines are imaginary lines in plan view that connect points of equal height above a datum or bench mark.
Each contour line represents the form in which the site acquires over a specified elevation that is why we have surveyors and topographic surveys vs. metes and bounds surveys
Contour lines are continuous and never intersect each other. They change in shape, but never in elevation.
Various ground shapes as represented by contour lines and site sections
contour lines spaced far apart indicate a flat surface
contour lines spaced evenly describe a constant slope
contour lines spaced close together designate a steep rise/fall in elevation
Without the elevation numbers you could not tell these forms apart! Contour lines & Topography
Contours must match existing grades at property lines. existing new
Each contour line is placed with an elevation marker.
states the height of the contour relative to the site.
Elevation markers are documented in intervals depending on the size of the plat.
Smaller sites or sites having gradual slopes may show 1, 2 or 5 feet markers,
Larger or steeper sites may show markers in
10’, 20 or 50 feet markers.
The soil type affects:
the type and size of a building’s foundation system
the drainage of ground and surface water
the types of plant material able to grow on a site
All buildings rely on soil for their ultimate support. The underlying foundation is effected by the soil’s strength.
The types and locations of plant materials affect:
the site’s micro-climate
Solar radiation, wind, humidity, air temperature
the definition or visual screening or exterior spaces
the absorption or dispersion of sound
The light shelf is an extremely useful tool. This mechanism, a horizontal surface at or above eye level, serves to reflect light falling above the vision window up onto the ceiling and therefore deeper into the room. At the same time, it reduces illumination immediately adjacent to the window, where illumination levels are typically too great to work comfortably. http://images.google.com/imgres?imgurl=http://www.afcee.brooks.af.mil/ldg/s01LandscapeDesign/graphics
