A green home is basically that kind of a house which uses technology and materials which are eco friendly. The paint used in such homes does not emit any harmful fumes, the materials used for flooring and furniture is all natural. The glass too is also very environment as they are made from renewable or recyclable material and provide natural heating facilities.
The energy resources of the house basically are taken from a renewable source. For this you would need a government based green home construction certificate too. The lightings which are used can also be environment friendly. Energy saving bulbs and tube lights are used in a large number of contemporary homes which makes it easy for one to save up on the electricity bills too. Green homes are cost effective and even healthier to live in.
