- A home that is energy-efficient during its operation. If it is located in Europe or North America where the weather is cold, it will not need a lot of energy for indoor heating.

For night lighting, the house uses LED lamps.
- It has to be a house that has been constructed using environmentally friendly materials, both in the physical construction of the housing components and in its interior decoration. The construction materials for the house, if possible, should be taken from the local resource.
- A home which has designed to have adequate natural lighting and ventilating system
- And the last but not the least a home that is comfortable, safe, and healthy for its occupants.
