The concept of design with energy:

Energy as “the capability of doing action or effect”. Everything has an energy which appears in the different effects produced by it. For example, a person has positive energy simply if he has good characters such as being joyful, optimistic, generous, calm, etc, while he has negative energy if he has bad characters. Increasing the positive energy for a person leads to improving his balance, vitality and accepting life. Thus, positive energy is one of the principles for good life
Positive energy in interior design and furniture:
Beauty energy: artistic characteristics of design elements
Arranging energy: design elements with specific geometrical characteristics to emit positive energy to balance the harmful negative electromagnetic energy.
Biological energy: varieties of plants that have great ability than others to remove harmful air pollution in interior spaces
Natural and non- natural energy in interior design and furniture:
Natural energy in interior design and furniture is a positive energy generated from using natural design elements with good characteristics, and under suitable circumstances it performs the role God created it for. Red color satisfies harmony, balance and unity with the place and reflects positive energy. Yet, it produces its negative characteristics if it is used in reading or sleeping rooms or homes for old people, because these places need calmness and concentration. These characteristics are not available in the red color, but exist in the blue color thus satisfying balance, harmony and unity with the place and reflect this positively on the place user.
The non-natural energy is the one generated in case of using non-natural ( artificial) design elements where under suitable circumstance it has at the same time both positive and negative energy . It has positive energy when it achieves the suitable design character and hence reflects positively on the user of the space. Also, because it is a man factorization, it has negative environmental effect which harms the user of the space.
