A Passive House is a house designed to use Passive Solar Design principals to drastically reduce its energy demands by making full use of the energy supplied by the Sun, this thereby reduces ecological footprint of the building.

Passive solar design refers to the use of the sun's energy for the heating and cooling of living spaces. With this approach, the building itself or some element of it takes advantage of natural energy characteristics in materials and air created by exposure to the sun.

Passive systems are simple, have few moving parts, and require minimal maintenance and require no mechanical systems. Often the thermal characteristics of materials are extensively used, often termed as Thermal Mass design.

Passive ventilation is a natural ventilation system that makes use of natural forces, such as wind and thermal buoyancy, to circulate fresh air to and from an indoor space. 

Photovoltaic relates to the production of electric current at the junction of two substances exposed to light.

Must often used with photovoltaic cells, i.e. solar panels. Where the cells are connected together to make a solar panel.

Geologic theory that the bending (folding) and breaking (faulting) of the solid surface of the earth results from the slow movement of large sections (plates) of that surface.

Substance, especially man-made, that pollutes or contaminates an environment.

The wind direction most frequently observed during a given period.

Energy embodied in natural resources (e.g. coal, crude oil, sunlight, uranium) that has not undergone any anthropogenic conversions or transformations.

This is the process used to create biochar.
