The sun in Fengshui 风水（風水）

Sun in Chinese is 太阳（太陽）tai yang, the great yang, the great brightness. Could something be more representative of the forces than the sun? Of course there is a myriad of energies in question, but few as strong as the sun. That is why I arrange the bagua八卦，the eitht trigrams, acording to the sun.
The sun will bring warmth for parts of the house in cold climates and it’s lack can bring desastrous effects in humid and hot climates, like spreading of fungi.
You could arrange the house to receive the beneficial sun of the morning during this time, arrange some cold machines like refrigerators to not receive direct sun, and some parts of the house that are prone to fungi and humidity like bathroom and kitchen to receive sunlight.
