The concept of green house is very daisy. Here we find lot of inorganic components being used in name of replacing natural materials.  For example door: synthetic doors are used instead of wood. Coatings are high end chemicals like polyurea, PU, epoxies etc.  Facades over building reflect the sun heat and cause global warming or carcinogen.

Let us presume we retain all these for aesthetics and convenience how to have a green house is a matter of debate and question, also is urbanisation a bane, how to handle water and air issues are some of the question to be answered. It is possible to still have a greenhouse and environment by adopting a good thoughtprocess. Let us start from base operation:

Excavation: for constructing high raise buildings and even some cases one floor structure soil is excavated which is then shuttled out, then, after putting required foundation as per design new soil is brought to fill the gap this means labour for loading excavated soil transporting the same and getting new soil which again involves labour for loading and unloading, transporting of soil which means pollution during transporting apart from labour charges and traffic congestion .

Solution for this is, the excavated soil can be used to make air dried bricks or pavers which can be used for compound, pavers and curb stone this will not only save transportation cost and will also reduce pollution caused during shifting of soil after excavation and also while refilling. Addition to that one will be saving cost on curb stone, pavers, bricks for compound etc., this gives employment for the women from the same labour camp. Bricks are air dried so no power is required and it saves cost on pavers/curb stone/bricks. If the available soil is low or in excess It can also be used for re- filling the gaps between pillars etc and also for plant support.

If the new building is coming in place of old one then demolished building debris can be used for making plaster mortar, bricks or column this again reduces cost and also pollution during transportation.

Paint can be cementations so that harsh chemicals need not be used to make it. A ceramic based coating on roof top will reduce the ingress of heat resulting low usage of fan/Ac during summer.

Use of special coatings can eliminate tiling in areas like stairs, common areas, portico, car parks etc. at least if not entire area there by minimising use of stones like sadarhalli to marble or even vitrified tiles which results in faster construction, seamless protection, colour full area with waterproof, crack resistance as additional benefits. Elimination of tiling means reduction of huge pollution of labour and time, as it asks for shipment of cement, sand separately and huge labour camps to fix, shipment cost and transportation from long distances is another bane (for example Marble from Rajasthan has to reach Bangalore).

The waste in form of mortar and concrete and broken block can all be pulverised and mixed in plaster with additives so that binding is not lost. This will save the expenses of shifting dead mortar and plaster with bebris.

Plaster used in a building is of enormous quantity this attracts multiple operation like hoarding of sand which chocks traffic on road when there is less space for hoarding as volume required is more. The number of trips required to feed sand is another pollutant since sand is not available the crushed stone powder which has been used has resulted in rampant abuse of mountains. Cement required for this has to be separately transported and stored instead If ready mix mortar is used this will reduce the number of trips in transportation resulting in less pollution and also less hoarding space apart from reduced labour cost. I illustrate this with example. If a hose has to be plastered then the process involved if everything is properly done is getting sand and hoarding in the working site. If there is no space then it will be hoarded on roads resulting in chocking of traffic and also gutter nearby. The sand gets washed away in rain and also neighbours take away in bits for their use without our knowledge all these results in loss of quantity apart from inconvenience which means loss to owner after this sand needs to be sieved which means again cost of labour so sieved sand need s to be shifted inside the site as required and mixed for days job with cement and one has to get cement from stored space for mixing site which again consumes labour time vis-à-vis labour cost. The so mixed cement water and sand will be  kept for entire day and used which means almost drying reaction initiated mortar will be disturbed every time shifting takes place so it is better to have premixed mortar in dry form and the same is used as per requirement by adding water so that mortar will be fresh and quality is also assured. This reduces labour cost on sieving of sand, shifting cement and sand to site and also movement time. Another great advantage is to render mortar each mason needs 2 helpers in case of ready mix plaster one helper can cater to 3-4 mason this again reduces labour cost. The reduced labour force means less menace in site low pollution caused due to their improper handling of daily chorus like cooking food, open field abuse for relieving nature call etc.

Using solar power where ever possible is another option to reduce pollution. Having garden even if it is rooftop one and using kitchen waste as fertiliser for it is another welcome step.

I am not writing this like a cribber to point mistakes or inconvenience caused to public including owners. We can offer technology to make air cured bricks etc using native soil, our PERFECTBOND-S will support this activity one can buy it and make products from soil. PERFECTPLAST is an excellent plaster mortar which has crack, heat and water resistance, available in suitable packing of 5 kg for small repairs and 20 kg for projects.  PERFECTCOAT-TR is an excellent heat resistant coating which is also water and crack resistant. When coated over roof it keeps the inner rooms cool. PERFECTCOAT-LM is good replacement to all tiles which can be used on concrete/metal/wood surface to get aesthetic and functional value as it replaces tiles of all sort including kitchen counter tops and can be applied in shorter period with less problem as they are low labour intensive. RAVISHAKTHI can do both water heating and also provide power from solar including led lights.
