SELECTION OF BUILDING, MATERIALS & OTHER TIPS


a)Use more materials that are ecologically sound and breathe, e.g. bricks and wood breathe where as steel, concrete and glass do not. Even adobe bricks, soil stabilized bricks are better.

b)Avoid materials that are hazardous, e.g. paints that have harmful solvents, modified timber derivatives which use formaldehyde which give out vapors, asbestos fiber which cause asbestosis.

c)Regarding lighting,give priority to health aspects.Sun light has many advantages.

d)Ensure all workplaces have day light.

e)Use windows that can be opened. (This is very essential in our situation where electric supply is erratic. Air conditioning makes the air drier. If the filters are not cleaned frequently, the air we breathe is also of doubtful quality. In centralized air conditioning, the design is based on number of air charges per hour. As part of the air is returned, it has been observed that it sometimes contains cigarette smoke)


g)Use natural light especially in stairs and corridors.

h)Restrict electrical installations to a minimum.

i)Minimize air conditioning.

j)Avoid use of ceiling boards; they invite accumulation of dirt and fungus. The frame work above may attract movements of rats.


l)Avoid heavy drapes: They invite cockroaches and lizards in tropics.

m)Avoid drinking water use for production, flushing etc.

n)Use grey water (water from bath) for alternate use wherever possible.


p)Equip toilets with water saving devices, even in kitchens (like water saving taps) if large volumes are consumed.

q)Plan waste disposal

r)Install system that separates biodegradable from others.

s)Install waste processor.

t)Organize compost for organic waste.

u)Keep the top soil excavated separately and use it for land scape.

v)Minimize paving, allow the soil to breathe, minimize sealing of surface by using concrete and asphalt.

w)Use interlocking sets on compacted gravel (They can be used for drive ways also if built properly.) They allow rain water to soak in, create seepage pond.

x)Use indigenous plants; they resist the local pests best. Give preference to native shrubs and pond.

yDo not use organic manure or weedicides and pesticides .

z)Use roof top for gardening, solar energy collection.Plant climbers wherever possible to be heat shield for walls.
