In our 1 & 2 floor duplex house, we added ventilators only
in the second floor. Second floor roof slab is exposed directly
to the sunlight and will be cooked nicely in summer.
As the ventilators are above the lintel line, one problem
is how to provide for rainfall protection. We also used the
EBCO friction stay hinges, so that the ventilator can be pushed/pulled
vertically. Not sure how this arrangement will pan out.

I am thinking about the Glass Bricks to be installed between the Lintel level to Roof level ( running 4 ft Block work and 2 ft Glass brick around the exterior walls) which could serve to get the light and an element for interior design too. Any suggestion/disadvantage for this method ?

i have a duplex wall where i have installed the glass bricks between the height of 9 feet & 15 feet. the bricks are not set up in a continuous order, rather it is installled alternatively between the regular walls due to security reasons.

Hi,
You have to take a cross ventilation and exhaust view of the building.

Now you wanted to know whether you wanted keep a exhaust between your lintel and roof levels.

1. If the wall that is being constructed is a western or a southern wall, then keep a small opening, say 3" below the roof slab of size say 12"width and 6" height. This you do only if you anticipate a lot of suns heat falling on this wall and there is no much cross ventilation in the room.
2. If there is a double heighted roof, then provide a sky light with no windows on the double heighted volume, but a turbine ventilator attached to the sky light for a wonderfull exhaust system.
3. It is better to keep ventilators in the bathrooms and toilets, rather than in lviing room and bed rooms.

all the best.
