Hints
for Design
|
|
HOT DRY CLIMATE
|
|
DOS:
|
DONTS:
|
- Use reflective
devices on roofs and walls exposed to the sun both for sky and ground
radiation
- Grow grass and
use shade devices
- An inward looking
layout
Uninhabited spaces should be placed on the west side to baffle the impact
of the sun.
- Compact shapes
are preferable yet they should be somewhat elongated on the e-w axis.
- Thick insulating
materials should be provided.
- A double roof reduces
heat.
-
East &
west walls should be shaded. The walls of daytime should be made
of heat storing materials, while walls of night rooms should
be of light heat capacity.
|
-
Avoid sun pockets
and radiation glare from sky.
-
Avoid dust and
sand being carried indoors.

CLIMATE:

|
SITE AND ORIENTATION:
|
WALLS:
|
High elevation facing the
windward side are desirable.
Southern and northern slopes
rather than eastern and western ones are preferred because they receive
less radiation.
Dense high vegetation is
preferable for shading and to avoid interference not be allowed.
|
Roof overhangs are required to prevent direct sun from striking
the walls.
Avoid moisture penetration into the structure.
Materials used for roofs and walls should be relatively
non-moisture absorbent and not susceptible to fungus mould growth.
|
|
HOUSE PLAN:
|
OPENINGS:
|
Interpenetration of indoor-outdoor areas.
Through ventilation is required for comfort. Freely elongated,
high buildings are preferred. Paving should be avoided.
|
Ventilation is needed 85% of the year.
Features such as screening, louvers, jalousies and
grills are useful to admit air flow. Windows should be shielded from
sky radiation and glare.
|
| |
INTERIORS:
|
| |
Interior spaces must be shaded and well
ventilated. Flexible spaces are desirable. Floor materials must
be impervious to moisture. Reflective light colors in the pastel ranges
are best for avoiding glare both inside and outside.
