Project Name : Eco Friendly House
Theme Name : Natural Resource & their Conservation
Introduction: The prosperity of human civilization is based on harnessing the natural resources that Mother Nature has blessed us with. Since last few decades the competition amongst different nations to excel in various fields has resulted in the over exploitation of these precious resources.
Time has come to harness these resources in a judicious manner. Our model of modern house consists of doubled walls (inner is thin layer of good conductors of heat) in between these two walls runs a network of water pipes containing thermo-regulated water to maintain the room temperature.
Objective/Aim: The aim of this model is to increase the use of self generated solar electricity within a house, its practical application in various domestic activities, rain water harvesting and using the harvested water for various purposes like watering kitchen garden, supplying water for daily use and regulating the temperature of the house by an innovative mechanism. A setup of earthquake shock absorber has also been installed in this house which will minimize the tremors and destruction caused by the shock waves.
It is a model of self sufficient eco friendly house which contains roof top solar panels to meet the energy requirement of the house.
Roof top rain water harvesting installation not only provides water for daily usage but also it has been used in n innovative manner to regulate the temperature of the house.
Scientific Principles Involved: Scientific principles followed in this project are as follows:
Co-efficient of thermal expansion of different metalsare different which is used to make bimetallic strip for fire alarm.
Water has high specific heat capacity due to which it can withdraw or impart more heat energy which helps to regulate room temperature.
Rainwater harvesting is the practice of collection, storage and usage of roof top rain water for daily house hold purposes as well as for agricultural purposes.
Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained, but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes, especially in water treatment and sewage treatment in which undesirable constituents are removed by absorption into a biological film grown on or in the filter medium as in slow sand filtration.
A shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. It reduces the destruction caused by the shock waves of an earthquake.
Photovoltaic modules, commonly called solar modules, are the key components used to covert sunlight into electricity. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. The most common type of semiconductor currently in use is made of silicon crystal.
A greenhouse is a structural building with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible solar radiation (for which the glass is transparent) from the sun is absorbed by plants, soil, and other things inside the building. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. In addition, the warmed structures and plants inside the greenhouse re-radiate some of their thermal energy in the infrared spectrum, to which glass is partly opaque, so some of this energy is also trapped inside the glasshouse. However, this latter process is a minor player compared with the former (convective) process. Thus, the primary heating mechanism of a greenhouse is convection.
Lightening conductor works on the principle that whenever a charged cloud (-ve) comes near to a conductor, it induces an opposite charge (+ve) into it. Due to small area of the spikes, the charge density becomes very high which ionizes the air above it. The positive charge moves towards the cloud and neutralizes it.

Utility and further scope of the project: All economic activity requires some form of (commercial) energy. All energy production and consumption is directly or indirectly associated with some form of environmental impact which may affect the health or welfare of people other than the producers or consumers. In all countries, energy production and consumption are therefore subjected to a variety of laws and regulations which aim to optimize energy development
and use under the prevailing political, economic, social and environmental development priorities.
This project (model) will encourage the society as a whole to conserve energy and will develop a sense of respect for Mother Nature.
Further exploration of the effective use of solar energy and rain water harvesting techniques can increase the work efficiency of this project.
