Transpired solar heat collectors

Perforated wall panel that draws the air heated by the sun through perforations into a cavity. Heat calories are then driven into the building's ventilation system during cold days, and ejected directly into the atmosphere during warm days.

Natural ventilation

Supplying air to, while removing air from, an indoor space without the support of a mechanical system, but exploiting pressure differences between the inside and outside of the building.

Trombe wall

Storage and solar heating walls in components with high thermal mass which leads to indirect heat gains. They encompass a range of designs including classic, composite, water, solar trans-wall, fluidised and photovoltaic.
