While constructing a room it should be kept in mind that every room gets proper light. Electricity is the main source of energy these days. Main switch board and meter etc. should be fixed in the south-east portion of the building. In every room, switch board should be provided on the right hand side (While entering). It is not auspicious to provide switch board on the left or centre of the wall.

A building or temple where sun rays and fresh air do not reach is not auspicious and beneficial. As far as possible each room in the house should be so planned that it receives proper sun rays and maintains proper flow or air. In modern times, many huge buildings are built such that not only the sun is not visible from inside but it does not receive even traces of sun light. Flies, mosquitoes, germs may, of course, enter it without any check. Electric lighting has replaced sun light and fans, coolers etc. are used to maintain flow of air artificially. The un-natural arrangement is harmful to health and produces adverse effects on the eyes, lungs and heart. Soon the inmates have to suffer from respiratory troubles and diseases or eyes. They have to consult the doctors again and again, and have to take medicines regularly and use spectacles.

Therefore it is necessary to keep the importance of proper circulation of air and light in mind for the healthy and long life of the inmates and the house itself. There are traditions in our country of worshipping the rising sun. Ancient scriptures have mentioned methods of curing several diseases, like anaemia, impurity of blood, dyspepsia, etc. with the help of sun rays and passing the sun rays through water filled in glass bottles of different colours. Exposure of the body to mild sun rays also cures many diseases. Modern architects generally ignore this fact in an attempt to earn more money by utilising maximum space. Sunlight and natural air are very much necessary for the durability of the house and health of the inmates. This should be kept in mind. Proper ventilation and exhaust fans must be provided in proper directions.
