// Descripción
The new Go uter refuge in the Mo nt-Blanc, o ne o f the highest in Euro pe (38 35 m altitude) replaces the o ld building, inadequate
and dilapidated building dating fro m 19 6 2. This building o vo id structure wo o d and metal cladding, real co nstructive and
technical challenge facing the laws o f nature is lo cated 10 0 0 m belo w the summit o f Mo nt Blanc, the mo st frequented ro ute by
climbers.
Started in spring 20 10 , the site, due to extreme weather co nditio ns, was o ver three spring-summer seaso ns, five mo nths a
year, and was co mpleted in summer 20 12.
Designed to acco mmo date 120 peo ple, the shelter o perates aut o no m o usly:
thermal energy co mes fro m so lar co llecto rs and electricity with pho to vo ltaic panels.
the pro cessing air and the heating is pro vided by a do uble flo w ventilatio n system and a ro tary exchanger.
Sanitatio n is based o n recycling.

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

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
