SOLAR HEAT - LIGHT - NATURAL SETTING
The sun, source of all life is an integral part of THE TEMPLE OF THE SOUL. Windows in the east-south-west-north exposures, bring in the light at different times of the day, in different rooms with different intensity to coincide with the specific needs.
For example:
 All eating should occur in a very well, naturally lit area hence favouring natural digestion.
 As the sun rises in the morning, the gentle light bathes the whole house with renewing life.
 The roof shall have skylights or skydoors in the appropriate areas. The sun's energy is also harnessed to heat up the living space by using different technologies such as mass, windows in the appropriate direction, the "trombé" wall, etc. In my many years of experiential knowledge in building, harnessing the sun's energy and natural light, I have witnessed dramatic changes in people's consciousness as they integrated with these energies. The natural outdoors feeling brought indoors through strategic glass-windows-solarium installation is simply naturally-purifying.
 Full spectrum lighting is used during the dark hours, as this type of lighting has the full spectrum of the colour of light, and is the closest to natural daylight. Many health benefits are derived from this system of lighting.
