By Feng Shui standards, “a healthy home” has fresh air flowing through its interior space, is free of toxic influences, and is balanced in its Yin and Yang qualities.

The first indicator for a healthy home is that the interior space is continually cleansed by Natural Energy Forces - sunlight and air. Airing one’s house daily, weekly, monthly with the turn of the seasons, is important. Commonly, a house is aired in the springtime, however, regular airings are preferable. Once a day brings vitality into a home or office.

Qi like breath, is vital for life and health. Qi flows not only through an environment (a landscape, a home, building or office), but is also affected by seasonal changes and planetary influences. If the environment has for example a polluted landscape, or the house is cluttered and dirty, Qi is re-qualified and can not obtain best results.

Your want to increase the circulation of Qi in an indoor space that you may be allowed to breathe and everything in the interior space also breathes. If the design of the house or building is well executed, air flow will reach every corner, flow through every room and cleanse and invigorate every area of the interior space.

Feng Shui or Kan Yu addresses the flow and change of Qi through a landscape over time. Kan means time theory and Yu means geographical theory. Qi is a living, dynamic energy which is constantly moving and changing.

There are four aspects of Qi, all of which are necessary to obtain the highest effects of Beneficial Qi:
Qi is always moving
Qi is always changing
Qi creates patterns
Qi has a direction
When any of these aspects are not in place, Qi is impaired.

There are Feng Shui expects called “dragon people”, or lung jen in Chinese, who assess environmental Qi. Understanding the principles of environmental Qi and its “generation and destruction” cycles is important. There are three phases of Qi: sheng, si and sha. Sheng means moving upward or waxing. Si means dying or waning. Sha indicates harmful energies. “Beneficial Qi indicates “the breath of Life”.

Sheng Qi is a “beneficial qi” that supports life
An environment that holds sheng qi feels bright and fresh; animals are healthy, the external environment has predominance of Natural ingredients - mountains, greenery, water, woods, ocean etc and the people are joyful and prosper. A room holds sheng qi when there is good, fresh air, good lighting both natural and artificial; there are live plants ; the room is clean and organized; there is a pleasant view from the windows and the floor plan is not irregular and there is not disturbing noise.

Si Qi indicates “the breath of death”
Si qi is present in an environment which is dilapidated and unkempt. The earth energies are depleted and the vegetation is poor, animals are sick and the people are weak and impoverished; people hold si qi when the are depressed and extremely ill.
Sha Qi indicates an environment where the Yin and Yang are not in accord, the Qi breath “hurts” and is discordant
Sha qi comes from negative conditions both above and below the ground’s surface. Below the surface of the earth the sha qi is called “noxious rays” and above the ground “poison arrows”. An environment has sha qi when it feels dangerous or strange; noxious rays drain one‘s energy and cause illness. It is possible to feel fatigued, nervous and frightened for no apparent reason. When a building is constructed on low stagnant ground, around which the air hangs heavy and stale, sha qi is present. “Poison arrows” are irritating conditions that originate above the ground and come from the construction of the building and artifacts. Sha qi is present when the environment has a bad smell such as mildew or something rotting; is dirty and oppressive; has a depressing and/or threatening view; has cracks in the flooring, foundation, construction, walls etc.
