Inspired by the vernacular architecture, the volumetry considers the inclusion of part of the built volume into the slope of the field.The habitations of primitive civilisations were often caved into the land or covered with soil. The advantage of integrating theconstruction into the surrounding land and of covering it partially of totally with grass is that the soil is a natural moderator oftemperature. Even below the freezing point, the temperature of the soil remains relatively constant. Thus, a construction locatedunder the land surface will have a very stable temperature all year long as compared to one located on the surface. Depending on itscharacteristics, the soil slows down the caloric exchange to such a degree that very small quantities of energy are needed forsupplementary heating or cooling of the place.The habitations are facing South and the back part is engulfed by the slope of the field. The upper storey is conceived for dailyactivities and structured so that it benefits from a passive greenhouse effect in winter. The window surfaces of the upper part arefacing South and West for capturing solar energy; this system gains additional heat by using 60-75% of the solar energy hitting theglass. In summer time, the window surfaces can be covered with wooden shades for thermoisolation.The project avoids major alterations of the topography of the place and of the vegetation, and limits the used surface for the buildingin favour of the existing vegetation. The roofs of the habitations are partially covered with grass. This confers a good integration intothe landscape and maximises the surface for vegetation at the site. The trees and the short vegetation contribute to the passivecontrol of the shade.Supplementary heating is ensured by air-water heating pumps. The running water comes from a near-by spring, and the used watersare directed to a micro station for biological purification before ending into a river situated close to the site. The hot running water issecured through solar heating systems.Natural ventilation is favoured by cavities of the East-West facades and is complemented by an auxiliary system for heating-coolingwhich captures air through a network of tubes positioned in the depth of the field.For the level buried in the soil, natural lighting is ensured by a light-tube system that captures natural light through an ingenioussystem of mirrors.From the functional perspective, the project innovates by placing the night area at the ground storey, the one buried in the soil, andthis confers a high thermal and acoustic confort. The day area is located in the upper storey and makes good use of the beautifulscenery of Rasnoavei Valley.

Quantum change and transferability
The project aims to achieve an original model for habitations placed on fields with increased slope, demonstrating the compatibilityof vernacular architecture and new technologies for optimizing energy consumption. This is a model which can be easily transferredand studied throughly.
[ Self assessment ]
Ethical standards and social equity
Since the contemporary habitations are a large consumer of energy, the project comes with a solution for an economical model,which is also an impulse for paying extra attention to green areas in the immediate proximity of the habitation.The project can beevaluated from the perspective of an attempt for fusing man with natural environment.

Ecological quality and energy conservation
The project avoids major alterations of the topography of the place , and limits the used surface for the building in favour of existingvegetation. Heating is ensured by air-water heating pumps. Fresh water comes from a near-by spring. The hot running water isproduced by a solar heating system.Natural ventilation is favoured by an auxiliary system .
[ Self assessment ]
Economic performance and compatibility
The utilisation of mainly local materials (eg, wood, sand, natural stone) and of local labour force lead to a good return on investment. Also, the integration of the built volume into the grassy soil makes the long-term maintenance costs to be relatively lower . Inaddition, lower exploitation costs are expected because of the massive energy saving for heating, cooling and lighting.

Contextual and aesthetic impact
The beauty of expressiveness of the natural landscape have generated a contextual architectural response. The built volumes aim abetter and organic blending with the natural environment. Although very contemporary, the architectural response stresses theprofound roots of a prehistorical life style and, in the same time, generates an ingenious synthesis between old and new.
