The home's arch shape (made from FSC certified timber) helps provide improved earthquake resistance compared to perpendicular structures.

Integrated solar panels capture the sun's energy while providing shade.

The Pearl incorporates an array of “passive solar” principles that harness the sun for heating and take advantage of air movement for natural ventilation.

And it doesn’t stop there. The roof can be insulated with a layer of air and cork beads, external walls are made of 12 inch-thick compressed straw, and the design can incorporate <a href="http://inhabitat.com/som-unveils-plans-for-a-green-geothermal-district-in-beijing/">geothermal</a> and <a href="http://inhabitat.com/gorgeous-energy-neutral-amsterdam-townhouse/">wood pellet</a>-fed heating systems.

The bay windows are fitted with an automated venting system - during the winter they soak up the weaker sun, whilst in the summer these huge windows allow every room to be bathed in sunlight.

The white steel roof reflects sunlight in the height of summer to keep the interior cool.

The design of the building itself allows for it to be placed in all sorts of climates and geographies.

The Peal passive solar house looks just as good from the inside as it does from the outside.
