Presentation Transcript
solar orientation
Solar Orientation
  • Becoming more important because of energy conservation.
  • NORTH SIDE – cooler – Because it is shaded
  • EAST SIDE – Cool – Gets little sun
  • WEST SIDE – Warm – Receives a lot of sun in the afternoon
  • SOUTH SIDE – Warmest – Almost constant exposure to the sun.
  • **The ideal orientation absorbs as much winter heat as possible and repels excessive summer heat.
the perfect orientation
The Perfect Orientation
  • Would be to have a rotating house.
  • As this is not practical the most effective way is to design the roof overhang to its full effectiveness.
  • As the angle of the sun differs in the summer and the winter, the length of the overhang must be considered.
wind orientation
  • The term prevailing wind refers to the direction in which the wind typically blows.
  • The prevailing winds in Fergus blow from North to West but change depending on where you are.
  • This information can be found on the Internet by searching climate or microclimate of a region.
  • In planning a home site, select an area with protection from the prevailing WINTER winds
  • Landmass, other buildings and vegetation can provide protection from prevailing winds
  • Placing a home on the crest of a hill will provide the best view but it will also maximize the force of the wind.
  • The shape of a roof can deflect prevailing winds and the orientation of the house will affect wind flow around it.
noise orientation
  • Locate rooms requiring quiet away from the source of the noise.
  • Isulation helps
  • Trees baffle noise
  • Earth berms baffle noise
  • Control vehicular traffic
lot orientation
  • The lot orientation is affected by the size of the lot, the zoning bylaws that restrict the and setback and the access (location of driveway and parking) to the structure.
  • Small lots present small flexibility
soil considerations
  • The stability of structures relies heavily on what we put the structure on
  • Questions that need to be answered about the soil when looking at placing a new structure on it include:
  • How much weight can be placed on it? (lbs/sq.ft)
  • How much settlement can be expected?
  • How will the soil act under wet and dry conditions?
  • What is the best type of foundation to use?
  • What kind of drainage is there?
2 basic classes of soil
2 Basic Classes of Soil
  • 1. Cohesive Soil – One who’s particles tend to stick together, especially when moist. (example clay, silt)
  • 2. Cohesiveless Soil – One who’s particles do not have the tendancy to stick together under any given conditions (example, sand and gravel)
terrain considerations
  • A single level or two storey home is well suited to a level or gently sloping site.
  • Sloping sites are more suitable for back splits or other multilevel homes.
homework assignment
Homework Assignment
  • Consider the type of lots that would be best suited for a 2-Storey Home, a Bungalow and a Multi Level home.
  • Next create a list of advantages and disadvantages for these types of homes.
