De scripció n de la arquit e ct ura : Established in 38 35 meters, o n a plo t o f 20 0 0 m² facing west o verlo o king a ro cky
o utcro p, subject to winds up to 250 km / h and temperatures o f -40 ° C, the architectural co ncept was co nditio ned by his
enviro nment. This situatio n led to a fo cus Harmo nic Energy determining the shape and o rientatio n o f the shelter. To tame the
wind, we studied fluid mechanics and aero dynamics o f the envelo pe. Thus o ur research o n a co nvex structure led us to a plan
ellipse then pro jected in three dimensio ns, an ellipso id o f revo lutio n. The main axis o f the ellipse was placed into the
prevailing wind to guide the depo sitio n o f sno w in a kettle o n the back o f the building. To transpo se the shaped structure, the
elliptical plan was translated into segments o f a circle, divided into 128 equal parts o f trapezo idal o r rectangular facets. This
fo rm is bo th simple and smo o th, has been pro po rtio nally acco rding to the principle o f harmo nic paths, the plane and alo ng
pro file is part o f a go lden rectangle and the sho rt pro file in a square. The aesthetic dimensio n jo ins the ingenuity o f the
building. The wo o den o verall structure represents a vo lume o f 40 0 m3. The 720 m² o f ho llo w bo xes flo o rs based o n a grid o f
beams fixed to 6 9 piles - piles. The assemblies are made by sealing resin. The facets co nstituting the envelo pe are iso lated
by panels wo o d fibers and are co vered with satin stainless steel. Dimensio ned fo r transpo rt, the prefabricated mo dules are
assembled o n site.

The pro ductio n o f co ld water is ensured by the sno w melter, po wered by so lar thermal circuit and sto ring thermal energy
bo o ster. The do mestic ho t water (DHW) is pro vided by a 10 0 0 L preparatio n ball, fed via a heat exchanger in the so lar
thermal circuit and a bo o ster exchanger o n the seco ndary netwo rk (heating) o f the sto rage flask Energy (extra heat fro m
co generatio n). It was pro duced during the 20 13 seaso n 157.8 m3 o f co ld water at 10 ° C thro ugh the sno w melter; the
thermal energy needed fo r this pro ductio n represents 17 MWh, making it the largest item o f energy co nsumptio n o f refuge.
This energy was pro vided by so lar energy, valued at the average thermal senso rs, and partly by heat reco vered fro m the
