The centrally located atrium is the
defining characteristic of the architectural design. Open at the top,
landscaped with grass and a tree at the ground floor , the atrium
will allow uninterrupted low of fresh air throughout the minimizing
the need for artificial HVAC .The idea is actually inspired by the
traditional atria in old colonial Lima buildings, perfectly suited
for the mild temperatures and high humidity of the city .The
unoccupied ground floor area of the atrium also allow complying with
the 65% limit of ground floor usage without further setbacks and
providing maximum display span for shops.
At the loft floors the circulation area
surrounding the atrium is left open and gets direct sunshine and
fresh air from the open top of the atrium, General Iglesias Street
and also the neighboring plot on South until a building of same
height is completed there. The internal gardens at ground floor,
fourth floor and a garden terrace at the roof continue at the
greenery of the urban surrounding throughout the building .The
openness of the common circulation space eliminates the feeling of
being enclosed within walls and replaces it a feeling of “being
neighbors on the same street” among residents of the building and
eventually catalyze social interaction with each other.
Besides the natural ventilation and
lighting achieved with the atrium, other “green building”
principles will also be taken into consideration. These will include
gray water usage for landscaping, state of the art heat isolation,
glazing to minimize the need for heating in winter, artificial
lighting of common areas with eco bulbs and motion detectors, UV
blocking window blinds at loft floors to avoid overheating by
sunshine in summer, maximum use of recycled / recyclable / local /
non adhesive construction materials without compromising from the
durability and quality. Use of sun and wind power is found unfeasible
regarding the specific location of the site and current economic
factors.
To achieve a structure that is
modernist yet playful bare concrete is extensively used along with
contrasting transparent glass and brightly colored aluminum composite
panels. The panels covering the opaque surfaces of the ground, second
and third floors are chosen dark grey in order to emphasize the
interior lighting and decoration of shops and the restaurant, whereas
visually separating the commercial and residential sections of
building. In contrast to the lower floors each residential floor is
defined with a different vivid color making them stand out in the
neutral grey building.
Landscaping in, on
and around the building also contribute to the contrasting
characteristics of the architecture while blending natural and built
environment.
