Right Direction: The orientation of a building has a dramatic and easily measured impact upon the quality of life of its occupants. The sun’s energy is most nourishing when it is rising; buildings that face east bring the greatest benefits to the health and the vitality of their occupants.

Right Placement of Rooms: Because the sun has different qualities of energy as it moves across the sky, Vastu buildings are designed so that these energies correspond to the specific activities performed within the different rooms of a home or building.

Right Proportion: Proportion is a key to successful design in nature. Right proportion in buildings can connect individual intelligence to cosmic intelligence.

Natural, Nontoxic Materials and Solar Energy: Vedic architecture promotes natural and nontoxic construction materials. It also emphasizes filling rooms with sunlight and fresh air, as well as the use of photovoltaics for onsite energy generation.
