1 Chapter 13 Site Orientation

2 Introduction Site orientation
Placement of a structure on the property with certain environmental and physical factors Consider at the beginning of design process Sometimes predetermined Considerations Specific occupant needs (e.g., individual habits, perceptions, and aesthetic values) Setback

3 Terrain Orientation Terrain
Characteristic of the land on which the structure will be placed Affects structure type Level construction site is a natural location for a single-level or two-story home Sloped sites are a natural location for multilevel or daylight basement homes



6 View Orientation Building site may be purchased before home design begins People buy the view (e.g., mountains, city lights, ocean, or gold course) View sites are usually more expensive Architect must provide a home design that optimizes view View orientation can conflict with advantages of other orientation factors

7 Solar Orientation Sites with a solar orientation allow for excellent sun exposure South slope Southern exposure

8 Solar Orientation (cont’d.)
Establishing south Established in preliminary planning stages Determined by a line from the North Pole to South Pole with a compass Magnetic north True north

9 Solar Orientation (cont’d.)
Solar site-planning tools Calculate solar access Demonstrate shading patterns for any given site throughout the year Provide accurate readings for the entire year at any time of day, in clear or cloudy weather

10 Solar Orientation (cont’d.)
Solar site location Rural or suburban location with plenty of space Allows flexibility Other factors: Zoning restrictions with height requirements Avoid a site with large coniferous trees Sites with streets running east–west and lots 50' X 100' provide limited orientation potential Adjacent homes may block the sun


12 Wind Orientation Prevailing winds
Direction the wind most frequently blows in a given area Mountains, large bodies of water, valleys, canyons, or river basins may influence conditions U.S. prevailing winds are from west to east

13 Wind Orientation (cont’d.)
Site location Wind conditions can be found in almanacs, in the local library, and on the Internet Evaluate prevailing wind direction by calling the local weather bureau, discussing it with local residents, or searching the Internet Select an area where winter winds are at a minimum or where there is protection from them



16 Wind Orientation (cont’d.)
Summer cooling winds May be mild and contribute to a more comfortable living environment Comfort can be achieved through design for natural ventilation and landscape design


18 Sound Orientation A site within a mile of a major freeway can be plagued by road noise A site level with or slightly below a road can have less noise Landscaping designs can also contribute to quietness
