1. The windowed cupola, equipped with a ceiling fan, provides natural light as it draws hot air up and out of the house, one of the many energy-saving architectural features.
2. A white roof made of recycled aluminum helps keep the interior of the house cool by reflecting heat. It also provides heat from escaping when the temperature drops.
3. Operable (and good-looking) hurricane shutters block the sun's rays and protect the windows when ocean breezes turn to hurricane-force winds. The double-hung windows help promote airflow.
4. Smaller windows help to minimize solar heat gain, as does the light-colored stucco, which also holds up well to the damp Florida weather.
5. A 7,500-gallon concrete cistern, tucked discretely underneath a guest room, provides half the household's water needs. The system is supplemented by the municipal water supply.
