Portugal’s Modular Casas Em Movimento House Rotates to Follow the Sun at the Solar Decathlon Europe

Portugal aimed for the sky with their modular <a href="http://www.casasemmovimento.com">Casas Em Movimento house</a> at the <a href="http://inhabitat.com/tag/solar-decathlon-europe/">2012 Solar Decathlon Europe</a>. It's designed to follow the sun's east-west journey throughout the day in order to increase energy production, reduce heat consumption and adjust interior daylighting, and it has a protective <a href="http://inhabitat.com/tag/photovoltaic/">photovoltaic skin</a> that also generates a ton of energy. In fact, CEM+NEM- believes their house can generate as much as 12.220kWh of energy each year - which is <b>2.5 times more than it consumes</b>.

We visited Portugal's Casas Em Movimento at sunrise in Madrid

CEM+NEM-'s design is both ambitious and striking

The photovoltaic envelope provides protection and generates energy

By following the sun's east-west journey, the PVT system generates 40% more energy than standard homes

The interior lighting conditions change throughout the day as the home, conceptually, tracks the sun

The fresh interior design is largely comprised of cork

Modular, Casas Em Movimento can grow as the owner's needs dictate

This home has a clever water conservation program which harvests water wasted while showering

These panels can move in order to make room for the room behind the wall or to expand the living area

This home has one of the luckiest views of the Palace at Villa Solar in Madrid

There's a lot of space and movement here

The bed folds into the wall when necessary

Glazed openings ensure plenty of daylighting

Timber construction contributes to the home's sustainability

This is a closeup look at the cork and the robust infrastructure used to ensure the photovoltaic system can withstand all kinds of weather conditions

Cork is one of the most sustainable materials in the world and a great majority of it comes from Portugal

Technically, this home should be able to produce 12.220 kWh per year, while consumption is limited to just 3.885 kWh! Wowza.
