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 • 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 • 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 • 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.
