The mineral is halite, whose main chemical component is Sodium Chloride (NaCl). Halite is an evaporite mineral-i.e. it forms as a result of evaporating water leaving behind â¦ dissolved chemicals as mineral deposits.
Passive Solar Energy Definition. Passive solar energy is the heating space that utilizes the design of the house or building so as trap solar heat when necessary. This means that the passive solar ensures that the house is not too cold during winter and not too hot in the summer.
Passive solar building design is often a foundational element of a cost-effective zero energy building. Although a ZEB uses multiple passive solar building design concepts, a ZEB is usually not purely passive, having active mechanical renewable energy generation systems such as: wind turbine, photovoltaics, micro hydro, geothermal, and other emerging alternative energy sources.
