Question

3. How does the climatic requirements, site conditions and pollution level of any place affect the day-lighting features/elements to be applied in the design of houses there?

Answer 1

* Every house need to be design for better day lighting because of the reduction in artificial lighting which in turn helps in consumption of less energy and it's the impact on the health.

It's need proper planning for designing the building to achieve a maximum day light. There are many innovative devices to achieve natural day light such as reflectors, light shelves, fibre optics, light duct etc can be used.

*But overall it's not about the amount of opening provided to achieve day lighting but it's the positioning of the windows and othe ventilation in the right place.

* There are other factor which affect the day light distribution into the building such as climatic conditions, site conditions, pollution etc

* Climatic conditions play major role, suppose if the building is located in hill stations where during rainy and winter season we rarely have proper sunlight in a day and also due to the presence of more number of trees around the building will not allow the day light into building.

*Site conditions- if the building is to be located near a high rise buildings , all the day light is obstructed by the high rise building and the same case if the houses are located in dense areas where providing larger window or ventilation becomes of no use.

*Pollution level-in places where the pollution levels are high most of them spend there day indoors, if the Air quality index is poor people don't even bother about opening windows for daylighting because the poor air quality will distrub the health condition and which in turn results in poor productivity.

Daylighting is much essential source like any other need for the human being.
