Tips for Green Residential Complexes

· Water Recycling

- A small recycling plant can be devised so that all the grey water coming out from residents can be recycled and reused.

· Rainwater Harvesting

- Tanks on residential buildings or wherever possible should be constructed and used for harvesting of rainwater for future use.

· Garbage disposal

- All waste coming out from residents should be segregated into wet and dry wastes. As far as possible wets wastes should be recycled and reused as manure or compost.

· Planting Trees

- Trees should be planted in and around residential complexes. They not only spread greenery and generate fresh oxygen but they also keep the surrounding air cool.

· Environment friendly construction practices should be adopted.

· Power

- Energy efficient lighting systems should be used in flats. People should be made aware of the general tips they could adopt for saving electricity in their homes.

- As far as possible encourage use of natural day light in common areas of the building.

Case Study – China Builds Low Carbon City

14th May 2010

Turpan, a small town in Xinjiang province in china is going to experience its first environment friendly city.
The model city will be spread across 8.8Sq.Km. Solar energy and wind energy will be utilized to power the city.

For cooling and heating purposes, geothermal energy will be utilized. For public transport, the city will have zero pollutant electrical buses and taxis. The use of private cars will be minimized to least number possible.

Green Lifestyle

The idea of being conservative and environment friendly now has to become more than just an idea.

Many organizations in the professional arena are doing the best they can but this is not it. Smaller changes in the form of individual lifestyle changes in the personal arena can also help and contribute towards sustainability.

In summary we should look in conserving the energy that comes inside the house as also the one which goes outside as waste.

Generally, a home comprises of four main compartments – the bed, the hall, the kitchen and washrooms. These are the places one should look into.

The ideal way to save energy is to use electrical appliances in these four compartments efficiently.

For instance, check whether your ceiling fan has proper blades to spread enough air around the room. Now a days many electrical appliances come with a rating system which tells the consumer how energy efficient that particular appliance is.

Providing consumers with this type of information spreads eco-consciousness among them and they also start thinking the green way.

Another area where individual people can contribute is proper waste management in and around their own locality. Figures say that almost 70% of all household waste is wet waste.

The idea is that individuals now need to assess their own actions and how they impact the environment. This small idea of change in lifestyle can impact the environment to a large extent making it cleaner and greener.

Denmark generates Electricity from Thrash

The people of Denmark can now live clean and happily as their new power plant generates electricity from thousands of tons of household garbage and waste from industries.

This new plant is by far more cleaner than conventional incinerators which is filled with dozens of filters to filter out all pollutants and toxins coming out of it.

Because of this power plant, their energy cost as well as fuel costs have reduced to a greater extent. Not only this, but they have benefited the environment by diminishing the use of landfills and cutting carbon di oxide emissions. 

With all these innovations, Denmark now regards garbage as a clean alternative fuel rather than a smelling environmental hazard.

Chop but Don’t Kill

With the increase in industrialization more and more land is getting barren and trees are being cut down. Because of this the imbalance increases causing more and more problems.

To stop this from happening a new technique called transplantation can be adopted so that the trees are moved to a secure location and not cut down.
For this, first we have to identify which trees can be transplanted. Generally fruiting trees cannot be transplanted while non-fruiting trees like coconut, banyan etc. can be.
After identification of the tree, it should be marked with a circle around the entire diameter of the tree.

Dig all around the circumference of the circle drawn as well as deep under the tree so you will get a huge ball of dirt which should also contain the roots of the tree.
Another plot should be identified for the transplantation. The identified spot should have the same soil as the existing so that the environment remains same for the plant to grow in.

At the transplantation spot, dig a larger hole than you did earlier and put some fertilizers and/or manure inside if necessary.
Pick the tree up and place it inside the whole carefully. The tree needs so looking after for atleast 4 months before it starts to fruit again.

Green Electricity – Know How

v Lighting System

ü Automatic lighting saves a lot of energy. Consider placing light sensors, dimmers, automatic timers etc. so that the lights go off when not in use to save electricity.

ü As far as possible, use task specific lights.

ü 90% of energy consumed by an ordinary bulb goes off as heat rather than ight.

ü Replace all ordinary bulbs with energy saving CFL bulbs. They use 75% less electricity than ordinary bulbs.

ü Recycling one aluminum can can save as much energy to power a TV for six hours!

ü Don’t keep your video games, computers and other appliances powered on or on sleep mode. These devices still use electricity when not in use. Idea is to plug them into a power strip and shut off the power strip when the appliances are not in use.

ü Dirty tube lights and bulbs reflect less light and can absorb 50% of the light; dust your tube lights and bulbs.

v Air Conditioners

ü Use fans or table fans as the first priority of cooling during the summers. Celling fans cost 30p per hour to operate whereas AC cost Rs. 10 per hour.

ü Shading walls and windows of the host can reduce AC consumption by about 40%

ü Set the AC to work at 250 C to provide the most comfort at least cost.

ü Keep doors to air conditioned rooms closed as far as possible.

ü Clean the AC air filters every month. Clean filters help AC to work more efficiently and consume much less energy.

v Refrigerators

ü Refrigerator motors and compressors generate heat, so allow enough air flow around them. If the heat cant escape, the motor will run harder and consume more electricity.

ü Make sure to properly the door of the refrigerator so that the temperature is maintained properly.

ü Periodic maintenance ensures efficiency and less consumption of energy.

v Reuse & Recycle

ü Reduce waste by using recyclable materials. Decrease the use of disposables as they add to non-biodegradable waste.

ü Make sure to recycle what cannot be reused such as paper, plastic etc.

ü Refuse the use of plastic bags, use cloth bags wherever possible.

ü If you reduce your household waste you can save 1200 pounds of carbon di oxide annually.

Re – Cycle

- Recycling Plastics

Plastics are one of the major contributors of solid waste problem around the world. To make up and recycle such plastics an innovative idea in terms of “hand print” paved the way.

The idea was that the low micron plastic bags can be woven together to make them into a fabric which can then be used to make products. With this innovative idea, every plastic bag will be recycled and made to use again so the environment will be free of solid plastic wastes and will become cleaner and greener.

- Recycling Paper

With the increase in industrialization the consumption of paper is increasing day by day. Hundreds and thousands of trees are being fallen down to make paper and this leads to deforestation which leads to other problems.

Looking at this pattern of escalating use of paper and decreased recycling technique one should think to recycling paper on an individual level. People should be made aware of the fact and should be taught to recycle paper.

Ecological Footprint – The Know How


Devised in the year 1990’s by a Canadian ecologist. Ecological Footprint is a figurative count of the amount of resource a human being consumes to make it sustain itself. Here a human being can mean an entire neighborhood or entire mankind.

Some current research says that the collective footprint is 23% more than what the Earth can sustain.


Online footprint calculators ask the person taking the test a series of questions based on their way of living. The questions range from how they commute the food they eat, etc.

After the test the calculation is shows to the individual of the amount of footprint he has as compared to the country as well as globally.


After the result, the individual can assess his own way of living and how he can reduce and save on some things so that the footprint gets reduced

Go – Carbon Low

If you ask someone walking down the street what is meant by the most over used word now days – “Global Warming” or “Climate Change” he will naturally boast about the hot climate or talk to you about the weather.

But little does a common mane know that this phenomenon comprises of hundreds of other conditions ranging from unseasonal rains or excess of snow fall in the tropics, hurricanes, droughts etc. global warming is a universal truth.

Transportation and industrial combustion, which operates on combustion of fossil fuels and deforestation, are the largest contributors of the greenhouse gases like carbon di oxide, methane, ozone etc.

To prevent such disastrous changes to happen, we have to contribute to save our planet and make it environment friendly place to live in.

It is important to remember that every time one uses the air conditioner or a non CFC free refrigerator you are triggering global warming!!.

Carbon Emissions – Facts & Figures

- Sticking to the per capita emission approach, as stated in the Kyoto pact, the developing world demands that every individual has equal rights to carbon space.

- Advocates say the developed nations have occupied roughly 70% of the carbon space though they are home to less than a fifth of the world’s population.

- Poor countries want the rich to evacuate this space – reduce their emissions rapidly – or pay them to do so. This could impact how steep emission targets undertaken will be.

- Critics say the per capita line assumes there is an equal right to pollute or to the atmosphere as a global sink.

v 1510.4 million tons is the amount of carbon di oxide emitted by India.

v 1.3 tons is the per capita emission in India.

Leak Proof Your Home

Wall paints peeling off and the house walls going damp is a regular issue during the rainy seasons. One needs to take care of the leakages beforehand to prevent this from happening.

· Waterproofing in general terms means preventing water to come inside the house and damaging your walls and paints etc. this is a very important thing to do and one can’t just neglect it just like that.

· If, for any reason you don’t come to know from where the leakage or seepage is coming from then you should call the experts who can tell you what kind of leakage is there and how it needs to be fixed.

· Waterproofing is done in three stages – terrace waterproofing, house waterproofing and basement waterproofing.

· While waterproofing the terrace, make sure that the surface is dry and there is no stagnating water. Make sure that all cracks are treated properly with waterproofing compounds.

· While waterproofing in the house, first step is to ensure that all cracks are treated with a waterproofing compound. Tilling of wall also is a good idea, as this not only prevents water coming inside but also makes your house look elegant. While repairing of walls, do not use bricks as they are porous and allow water to seep through it. There are plenty of waterproof paints available in the market for use.

· Waterlogging in basements should be taken care of. If the basement is used for storage purpose make sure it is leak-proof first.

· Water problems if not properly checked and nipped in the bud, can pose to be a great hazard to the house in the future. Hence, it is very important to keep your house free from water related issues.
