1. Windows
"Windows are a very important part of both interior planning and exterior
v Traditionally, the window was considered an “opening” in the wall.
v Windows, perform several distinct functions. The most important of these is
normally the admission of “light” both from a practical stand pointed for it’s
psychological and aesthetic effect on the interior space.
v Any window design must satisfy the technical requirements of the relevant parts of
building. The main considerations are size, format, divisions, way of opening,
thermal and sound insulation, fire resistance and general safety issues, including the
use of security glazing must also be taken into account.
v A second function of windows is ventilation.
v A third function of windows is to permit vision, in or out.
v Fourth, windows sometimes serve as an emergency escape.
v Finally, windows are elements of architectural composition.

v The amount of light admitted depends on the number, size, location, and
transparency of the windows.
v The orientation of the windows will have an important effect upon the quality of the
light admitted.
v The type of glass used will also affect the quality of the light, as well as the quantity.
v If daylight is considered to be essential for the use to which a room will be put, then
windows are an unavoidable necessity.
v For workrooms which are 3.5m or more high, the light transmission surface of the
window must be at least 30% of the outside wall surface, i.e >0.3 AXB

v Where windows are used for ventilation, the requirements vary the season and the
v In cold weather the principal requirement is to deflect the entering air upward.
v In hot dry summer weather, it is often desirable to admit as much breeze as

v The vision function of glass in windows works both ways, permitting one to look out
as well as to look in.
v Where looking out is a pleasure that can be indulged, large clear glass areas should
be used with as few divisions as possible.
v The use of large glass areas not only permits the view to be enjoyed but also makes
the room itself seen more spacious.

Fig. (10) shows that the choice of windows is important in room planning and design.

Fig. (11) shows that large glass panes

enhance the view in this

Fi.g. (12) shows that the windows form living room
to the terrace are located where glass walls are large.

v Windows used for emergency escape must be easy to open, have reasonably low sills,
and openings large enough to go through without difficulty.

steel or bronze.

1.3. Other considerations
v Every work area needs a window leading to the outside world.
v The window area which transmits light must be at least 1/20 of the surface area of
the floor in the work space.
v The total width of all the windows must amount to at least 1/10 of the total width of
all the walls.
v Window size as %10 of room floor area.
v In planning the size of windows, the optimum daylight level relative to the purpose
of the room must be the deciding factor. For example, building regulations require a
min. Window area of 1/8 of the floor surface area for living rooms.
v The window width in secondary rooms can be chosen according to the distance
between the rafters.
v Minimum height of the glass surface is 1.3m.
v The total height of all windows must be 50% of the width of the workroom .i.e.

2. Doors
v Internal doors must be positioned in order to maximize the usable room space.
v It is necessary to decide whether a door should open inwards or outwards.
Normally doors open into the room.
v The width of doors is determined by it’s use and the room into which leads. The
minimum inside width of a door opening is 55cm.
v In residential buildings the standard door opening width are as follows.
1. Single-panel doors: main rooms approx. 80 cm, auxiliary rooms approx, 69 cm,
front doors to flats approx. 90 cm, front doors to houses up to 115 cm.
2. Double doors: main rooms approx. 170 cm, front doors 140-225 cm.
3. Door opening height at least 185 cm. but normally 195-200 cm.
