Clean Energy Technology

{Category}

High reflectivity paint

Paints that provide the same visible colour range as standard products but exploit the infra-red spectrum to reflect a greater part of the solar irradiation spectrum.

{Category}

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.

{Category}

Vapour permeable walls

Integrating pores in building materials to control air quality and moisture by tempering incoming fresh air with low grade heat.

{Category}

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.

{Category}

Radiative reflective roof

Sky-facing surface with optical and thermal properties for dissipating terrestrial heat to outer space.

{Category}

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.

{Category}

Building orientation for thermal performance

Optimal building orientation to allow solar radiation penetration in the winter and ventilation in the summer, by facing the summer wind stream.

{Category}

Bag digester for cooking

Renewable based stove - fuelled with biogas from anaerobic digestion stored in a tank.

{Category}

Structural insulated panel

Structural insulated panels, oriented-strand board or side of an insulating core.

{Category}

Vacuum insulated panel

Porous core enclosed by an air-sealed air and vapour barrier that reduces heat conductivity and component thickness.

{Category}

Dual flow ventilation

Heat exchange between incoming air and exhaust streams.

{Category}

Composite material digester for cooking

Renewable based stove - fuelled with biogas from anaerobic digestion and made of composite materials.
