The document discusses different types of windows used in buildings. It describes windows for habitable rooms, kitchens, and toilets with their typical sizes. It discusses controlling windows based on rain, wind speed, and outside temperature. Different types of windows are described like top hung, casement, sliding sash, and fixed lights. Windows serve purposes like natural light, weather exclusion, security, insulation, and privacy. The document also discusses stack ventilation and using clerestory windows to admit daylight.

Control on rain: window closed when it’s
raining
Control on wind speed: wind closed when
the wind speed is greater than a threshold
Control on outside temperature:
The current control logic compares the
outside air temperature with a lower limit.
No upper limit control exists for outside
temperature for window opening.
In a hot and dry climate, the control on
the outside air dew point temperature will
not be sufficient to limit outside air
admission at high temperature.

The vertical sliding sash
windows were often used in
Georgian Architecture such
as the ones shown above.
The two sliding sashes were
allowed to slide up or down
to provide ventilation.

8. • Stack Ventilation
It is caused by pressure,
For stack ventilation to work
properly there must be a
temperature difference. As the
warm air (usually given off by the
occupants and their computers),
which is less dense, in the building
rises, the cooler air is sucked from
the openings below.

10. Clerestory window
Windows are the most common way to admit daylight into a space. Their vertical orientation means that they
selectively admit sunlight and diffuse daylight at different times of the day and year. Therefore, windows on
multiple orientations must usually be combined to produce the right mix of light for the building, depending on the
climate and latitude. There are three ways to improve the amount of light available from a window:[3]
(a) placing the window close to a light colored wall,
(b) slanting the sides of window openings so the inner opening is larger than the outer opening, or (c)
(c) using a large light colored window-sill to project light into the room.
Different types and grades of glass and different window treatments can also affect the amount of light
transmission through the windows.

11. a clerestory;. clear storey,
also clearstory, clearstorey, or overstorey) is a
high section of wall that
contains windows above eye level.
The purpose is to admit light, fresh air, or both.
Another important element in
creating daylighting is the use
of clerestory windows
. They can be used to increase direct
solar gain when oriented towards the
equator.
When facing toward the sun,
clerestories and other windows may
admit unacceptable glare. In the case
of a passive solar house, clerestories
may provide a direct light path to
polar-side (north in the northern
hemisphere; south in the southern
hemisphere) rooms that otherwise
would not be illuminated.
This method has the advantage of
reducing the directionality of light to
make it softer and more diffuse,
reducing shadows.
