  • Hi, Do you know of any

    Hi,

    Do you know of any architects or designers who can help me build a environment friendly home? But I cannot really afford anything very costly...

  • Excellent article. Nothing to

    Excellent article.

    Nothing to beat natural ventilation. After the Divi Taluq devastating Cyclone in Andhra Pradesh,shelter houses were constructed and given free to the displaced. They have poor ventilation. Many did not occupy these box type houses. On the other hand the workers used to sleep in open and under the trees in the afternoon. Man prefers to live in harmony with nature.

  • Dear Prof. Premachandran In

    Dear Prof. Premachandran
    In my opinion this problem has arisen as nowadays there is a trend for replicating or getting inspired by buildings in the west. It is common sense that these buildings would not be suitable for the Indian climate. Most of these buildings are designed to be completely enclosed, air tight and have a large floor area width.
    Traditionally Indian buildings have always been open to the outdoors with the help of courtyards, chajjas, jharokhas, terraces, deep verandahs, ventilated roofs, ample cross ventilation, permeable building materials etc. But these so called "modern" buildings have scant regard for any of the traditional principles. So it comes as no surprise that this present vocabulary of buildings requires a tremendous amount of energy to function.
    Through such articles (like the present one), we at CSE hope to shed some light and make people aware of the importance of such simple but vital aspects involved in a building.

  • Dear Disha Singh, Your

    Dear Disha Singh,
    Your article on natural ventilation was a well timed one. It is now a known fact that almost all the states in the country are reeling under severe power shortages, and a major consumer of electricity is air conditioning. Here in kerala we had a rich tradition of embeded vaasthusasthra, and so we had houses that did not even require fans to be switched on even during peak summer time.But the present trend is to design buildings in which even fresh air has to be pumped from outside, at the same time take out stale air using heavy duty exhaust fans. It seems that our policy-makers have a totally distorted idea regarding development, In these parts it goes like this--fill up farmland, construct air conditioned shopping centres/malls, build wide roads. all this with scant regard to natural water flow natural air flow, flora and fauna, and topography of the area.

  • Dear Prof. Premachandran I

    Dear Prof. Premachandran

    I concur with the what you have stated in your comment. The worrying aspect is that India's growing dependency on mechanical cooling and ventilation is resulting in a sharp increase in electricity consumption resulting in a major shortfall in our already insufficient electric supply.

    Vaastushastra relies on harnessing natural elements to suit the climate, rather than creating an artificial and hi-tech internal environment which is energy intensive.

    Considering these aspects, it is imperative that professionals like architects, engineers and the common man must understand that harnessing natural ventilation in buildings will help reduce the electricity consumed in keeping them cool.

  • Dear Arun Thank you for your

    Dear Arun
    Thank you for your appreciation. I am in agreement with what you have said in your comments.

    In India we have a tendency to blindly copy the trends of the west even at the cost of our own traditional design principles. These passive design strategies, such as harnessing natural ventilation, have been perfected over centuries to suit our climate but are now being ignored.

    It is our endeavor through these articles to increase awareness among the public with regard to these simple but necessary aspects of building design.

  • Vaasthusasthra is basically

    Vaasthusasthra is basically the science of harnessing the 5 elements of nature-the panchabhootas and create living spaces that are in harmony with nature.Each region has its own vaasthusashtrsa depending upon the longitude and latitude.The indian vasthusasthra speaks of two sutras, the karnasuthra and the yamasuthra,dwelling spaces have to be constructed without blocking these two suthras, and the idea behind this is to allow free flow of outside fresh air inside and remove the inside stale air, we engineers call this process as natural draft scavenging.Even the old arab dwelling spaces made use of these principles of natural draft.You can come across wind towers above old arab buildings; these towers allowed outside air to pass through damp clothes and provide cool air inside, when the temperatures outside are scorching.Unfortunately, we have discarded all this and adopted artificial cooling and ventilation methods which are highly energy intensive.

  • It is sad that now a few

    It is sad that now a few architects are reminded of old construction practices after they have gradually done away with all ventilators,cross- ventilations,courtyards,Jharokhas, high ceilings,use of lime etc.I hope the feelings of these few will spread and people will not be denied enough fresh air for the sake of Rupees here and there.Arun B.Agarwal

  • We are unable to appreciate

    We are unable to appreciate our valued system because those who governed free India,were mostly educated in western oriented schools and colleges and most of the times where people ridiculed the Indian things. Now that science is proving that Oxygen,water,minerals are necessary for the health, there is beeline for water purifiers ,various health drinks supposedly fortified with vitamins and minerals. However, the need for oxygen is still not understood by majority of the people and most of the architects who are responsible for making ill designed unhealthy buildings.Your article serves useful purpose if people and more architects follow it.They do not have to reinvent wheel,it is already there in old buildings.
    Copy it if you so desire.Arun B.Agarwal
