Located in Roselló street in
Barcelona, on a plot aligned to the main
axis of the Sagrada Família, the hotel Ayre is the result
of a restricted ideas contest where the Wortmann Architects emerged victorious
with a proposal that emulates and updates Gaudi’s veneration for nature without
forgetting to create an architecture which is aware of when and where it
occurs.
The idea of the building was born as the
connection between two worlds: the hustle and speed of Roselló street and the plaza
inside the block, more calm and secluded. The visitor is invited to go through
the building as it was a public passage to the square, but not before
discovering a great void, an 8-storey courtyard tangent to the axis of the
temple which aims to be, with an abstract language, a reference to the towers
of the temple.
The central courtyard is both a main
space for the hotel and a key for the indoor comfort climate. Bioclimatically
works as an interior climate controller. In summer, it uses convection and
stratification (in the same manner as cathedrals) to assist the heating of the
ground floor public areas and hallways. Fans and motorized lockgates regulate
the excess of heat in the dome extracting it and providing warm air through a
free cooling system in intermediate seasons. In winter, through an intelligent
system, the loss of air through the skylight on deck is reduced to almost zero.
The roof of the hotel aims to
give the possibility to enjoy a unique view of the Sagrada Familia, and to make
possible the visit to the roof, it is provided a solar collection system raised
from the roof floor which works with vacuum tube solar collectors integrated
over a pergola.
The hot water production is
achieved through a combination of solar collectors with gas micro-turbine
support. The micro generation system is defined and calculated to supply up to
100 per cent of the thermal energy demand. For the solar energy storage, the
building has two tanks of 2,000 liters each. In addition to the two networks of
hot and cold water it is provided a third network of recycled gray water, a separated
wastewater system calculated for its reuse in toilets.
Building materials were selected
following bioclimatic principles, choosing those with low heat transfer
coefficient, recyclable, halogen-free and with a reduced environmental impact
throughout the production process and service life.
But beyond the building construction
it is through the efficient use of facilities when greater energy savings are
achieved, to this end, it was installed an energy management system in rooms implementing
switches to fully close the power supply when there is no occupation and
switches to close the cooling system in case of open windows.
