Water for drinking, other domestic and industrial purposes needs to be treated according to the purity required. Advanced technologies such as reverse osmosis attains importance in this regard. The development and use of thin film composite (TFC) aromatic polyamide membranes has made membrane technologies more effective and commercially applicable. Even though, the state of the art membrane technologies have many shortcomings including the insufficient salt rejection, insufficient permeate flux.
In the present study effort is made to improve the overall efficiency of commercially available TFC - RO membranes. It aims to synthesize a new membrane with improved efficiency, with the help of commercially available technologies. It also considers the testing the efficiency of the improved membrane. The study will also extend to the application of the membrane in water treatment industry. The membrane so synthesized donot cause any wastage of water and also it is environmental friendly. Thus the newly manufactured membranes could be used for the betterment of water treatment scenario in the industrial sector as well as in domestic usage, as a green technology.

Today, the world is suffering with food and water scarcity due to population explosion and unevenness in the climatic conditions. The world needs food which will satisfy its nutritional need and will be available at cheaper cost. One can grow the same in very small space. The world needs techniques which one can implement easily and without much of an investment.
Hydroponics is one of such technique. In hydroponics, plants are grown with the use of water and nutritional solution only. The nutritional solution contains the essential nutrients which are required for growth of the crops. The crops are artificially supported in the nutrient mixtures and made to grow using the nutrients provided only.
The water which we treat in our sewage treatment plants is mostly discharged into the drainages. But, as it was containing human excreta, it is rich in the N (nitrogen), P (phosphorous) and K (potassium). N, P, K are the macronutrients which are required for the growth of the plants. So, such water may be used by hydroponics system to grow the plants in the most economical manner.
This project tries to create opportunities for the people having arid land and small spaces to cultivate the crops for their daily need. The waste water generated can be used in this system to make it cost effective. This project tries to make the townships self-sustainable by creating an opportunity to grow the plants in small space by optimizing the resources. This may create a source of income to the townships and home owners.

In India water usage for commercial, residential, institutional building etc, is increasing day by day. Also because of changing habits of the users there is tremendous pressure on municipal co-operation. The increased demand is responsible for more wastewater generation, having negative impact on environment. Hence increase in water efficiency by integrating appropriate methodologies would suffice the associated problem.
A smart user in the city is armed with elementary infrastructure to give a decent quality of life, a clean and ecological environment through use of some smart solutions. However with awareness amongst the people and the policies of new government for Swachchha Bharat Abhiyan, the sanitation component in the rural areas is also gaining lot of attention.
After studying the feasibility and effectiveness of many methodologies, a prosperous solution for reducing the pressure on municipal co-operation in an integrated way, in turn would be effective for smarter buildings and hence the cities.

Currently India is one of the major energy consumer among the developing nations globally. Buildings in India generally are responsible for at least 30-40% of energy use and this demand is growing annually almost twice the average electricity growth in the economy. Green buildings leave a lighter footprint on the environment through conservation of resources and at the same time are energy-efficient and cost-effective. Energy efficiency is the first step towards achieving sustainability in buildings. Energy efficiency helps in controlling rising energy costs, reduce environmental footprints and increase the value and competitiveness of buildings.
The following paper will focus on the utilization of alternative sources of renewable energy for satisfying the energy demand in an institutional building. The primary aim is to assess the energy performance, based on monitored data for the existing institutional building and thus demonstrating the potential for energy conservation and thereby proposing optimised energy conservative techniques and also studying the feasibility and effectiveness of those techniques both energy and cost wise.
