What are the lighting and ventilation requirements in an auditorium?
One-tenth of the floor area excluding doors for dry hot climate. ii. One-sixth of the floor area excluding doors for wet/hot climate. No portion of a room should be assumed as lighted if is more than 7.5m away from the door or window which is taken for calculation as ventilating that portion.
Why do we need illumination?
We have evolved to not only love light, but to need light: we see best in the light and have limited sight in the darkness; daily exposure to light keeps us healthy and light is already used in a number of therapeutic applications; and since time began, light has allowed us to live productive lives, has kept the

What is 2700k in lumens?
750 Lumens – 9 Watt – 2700 Kelvin – LED A19 Light Bulb.
Does Auditorium need natural light?
Focus more on artificial light: In addition to the above, it is vital that the focus is more on artificial light as compared to natural light. Although most locations require the incorporation of both types of lighting, auditoriums need to maintain low lighting levels to make the projected screens more visible.
What is a scoop light?
In stage lighting, an ellipsoidal reflector floodlight (sometimes known by the acronym ERF which is often pronounced “erf”), better known as a scoop, is a large, simple lighting fixture with a dome-like reflector, large high-wattage lamp and no lens.
Is standard for illumination level?
Earlier it was common with light levels in the range 100 – 300 lux for normal activities. Today the light level is more common in the range 500 – 1000 lux – depending on activity. For precision and detailed works the light level may even approach 1500 – 2000 lux.

What is illumination level?
The quantity of light that illuminates a surface; measured in foot candles or in lux.
What is illumination measured in?
lux
The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.

Which electric discharge lamp gives highest lumens per watt?
Mercury vapor lamps are more energy efficient than incandescent and most fluorescent lights, with luminous efficacies of 35 to 65 lumens/watt.
How do you calculate light and air?
For every 10 feet of floor area you need one foot of natural light area. 2) Figuring ventilation is much easier. Natural ventilation must equal 5 percent of the floor area or exactly half the requirement for that of natural light.
How much natural light is required for a habitable room?
For example: For a 20m2 room the minimum area required for natural light is 10%. If a rooflight is installed only 0.6m2 would be required. If the roof light was only 0.3m2, then a window or equivalent borrowed light would be necessary.
What is natural light and ventilation?
A natural ventilator is an effective way to help bring fresh air and natural light into a building. By placing vents to let the stifling air out at the ceiling level and intake openings on side walls at the floor level, air will move throughout the interior space.
