Heliodome, Solar Concept of an Ecological Habitat
Fixed architectural volume sculpted by the path of the sun in its annual and daily cycle, the Heliodome captures solar energy in winter and saves it in the summer. Panoramic picture of the passive solar house Heliodome, zooming on the southern facade
Bioclimatic solar house made of wood, glass and concrete, the Heliodome is the ultimate answer to energy constraints and CO2 emissions. It provides free heating in winter and natural cooling in summer. Panoramic picture of the passive solar house Heliodome, eastern view
A new path in the search for higher energy efficiency and a practical answer to the principles and objectives of sustainable development, the Heliodome is an ultimate architecture which is modulable for multiple uses.
How does the sun sculpt the Heliodome ?The passive solar house Heliodome is a fixed architectural volume. It's position and shape are determined by the trajectory of the sun in its annual and daily cycle. The building embraces the sun's rays from sunrise to sunset, feeding on its energy and redistributing it in the form of living comfort. In this way, the Heliodome is, by its bioclimatic architecture, before all else a reconciliation of man with nature.The north face of the structure (the sloping roof) is designed by the trajectory of the sun during the winter solstice whereas during the summer solstice. the course of the sun follows the south facing glass façade.Under our latitudes :
- in winter, the sun describes an arc from the south-east to south-west, remaining low in the sky. The sunlight floods the interior of the building, bringing with it maximum light and heat into the Heliodome.
- in summer, the sun describes an arc from north-east to north-west, positioning itself very high in the sky. Solar radiation therfor scarcely enters through the glass surface into the interior, and because of this the building reamins cool.
Why the Heliodome ?

To allow us to naturally capture and store energy necessary for our well-being by intelligently optimizing the shape, orientation and construction of our homes. The energetic and thermal assesment of buildings will be crucial in the future. To make a common standard for the construction of houses self-sufficient in energy, is a goal which must be acheived. The Heliodome's bioclimatic architecture inspired by the sun's trajectories fulfills this objective. Simulations in accordance with the RT2000 have validated the theoretical model of the Heliodome so we can expect to make energy savings of between 80 and 90% compared to a conventional building. The prototype of our fixed solar house, equipped with probes and sensors, should prove the accuracy of these preliminary studies and validate in a practical way the concept of the Heliodome.
