This elegant home is a wonderful example of what can be achieved using sustainable construction methods. Reinforced concrete walls save huge amounts of lumber and are more fire resistant than wood framed walls. They save power, due to improved thermal performance, keeping the building warmer in winter and cooler in summer. Radiant heating, the most efficient, is provided through slab on grade construction; an added advantage is that no blower is required to move hot air, reducing airborne dust and allergens. In summer, the low tower draws hot air from the house and vents it to the atmosphere, acting as a natural air conditioning system.
