Low energy, solar houses with active and passive systems help to preserve environmental
resources and minimize the costs of utilities. The principle is simple:
The highly insulated walls on the north side absorb the warmth, the fully glassed
south side absorbs the solar energy from the sun. Trees providing shade prevent
over-heating in summer. Heat storers and providers, such as stone floors and wood
fire places, provide heat during cooler periods. Circulating systems and/or heat
pumping systems can even make a central heating system unnecessary! The material
choices are aimed at environmentally-friendly products without health risk due to chemical fumes.
Sourcing materials from other European countries, such as terra cotta from the
Pyrenees and timber from Slowakia, enable the building costs to compare to those
of conventional residential structures.
