Natural and Nontoxic Materials and alternative energy sources:
An important component of Maharishi Vedic architecture is building sustainably with natural, non-toxic materials suitable to the local climatic conditions. This includes using materials such as timber, brick, rammed earth, sun dried products and stonework, as well as natural finishes such as clay render, marble, ceramic tile, natural fibre for carpets, curtains and furniture, and healthy, natural, non-toxic paints and glues.
Vedic homes are not built near harmful electro-magnetic fields caused by such things as high-tension lines and microwave towers. Special precautions are taken, including shielding of all electrical wiring, in order to ensure that electro-magnetic fields are not propagated within the home. Ideally, all materials and appliances in Maharishi Vastus should be pure and healthy.
Increasing numbers of Vastu homes are being constructed with environmentally friendly, sustainable technologies, which more completely align the buildings with Natural Law. This includes growing numbers of buildings with small or zero carbon footprints. They use such technologies as solar hot water, photovoltaic electrical power, geothermal, daylighting and rainwater catchment.
