The urbanization Lliri Blau is being known as the
first class 100% Bioclimatic in Spain because it incorporates healthy,
recyclable materials, criteria for sustainable construction solutions that
promote energy efficiency and the use of automation technology.
Blau Lliri comprises 130 homes equipped with all
amenities and facilities. In this set there are, commercial areas, offices,
leisure centers, a nursing home and day care.
These homes are a European benchmark for green
building and the environment that meet the sustainability criteria. By
establishing a design process and a 100% sustainable and ecological
construction strategy, the architect has defined a set of parameters and 40
sustainable indicators used to determine the sustainability of a particular
construction.
In Lliri Blau this indicators have been faithfully followed, of which include: the use of recycled and recyclable materials,
using materials which have required little energy as possible to be obtained,
using materials that have generated the least possible amount of waste , local
labor, natural materials, the building to think to be able to recycle once you
have that down, that part or all of its materials biodegradable.
There was a carefully though: the perfect south orientation,
spatial structure, program, architectural design, the arrangement of windows
and channels of natural ventilation design gaps, so that, if only for its
architecture, buildings tend to heat in winter and cool in summer without any
mechanical system.
To enhance the building's bioclimatic performance, walls
were used with 'Termoarcilla block', providing a high thermal inertia, and it
is combined with hemp fiber and concrete block of 9.
This solution configures a breathable wall and
prevents the heat exit to the outside. Also for the thermal performance of the
building the prescriber has included use of roof gardens, greenhouses, frames
with gates to allow the passage of air and thus, natural ventilation and
thermal conditioning of the building.
Note that in these houses it was achieved a high
energy efficiency. It is estimated that due to the level of insulation, thermal
inertia and its bioclimatic component, buildings consume about 30-40% of what conventional
buildings of the same size and characteristics consume.
There were also implemented the use of alternative
energies. A good example is the hot water, which is generated by thermal
accumulator supported by captors with night rate.
Notable Features of the complex:
·
Consumes only 40% of the energy needed by buildings
with similar characteristics;
·
Ventilation and cooling natural system, based on
cross-ventilation and channels that receive air from the north direction, and distribute
for the houses;
·
Collects and uses rainwater for irrigation and filling
out the tanks of the toilets;
·
All materials are 100% ecologic, qualified through 40 sustainable
indicators identified for this purpose;
·
Bioclimatic buildings don't need air conditioned.
They are perfectly oriented to north-south with a perfect form factor and shallow
to allow cross ventilation. By its architectural structure and morphology tend
to cool in summer and warm in winter;
·
Using solar and electric energy with night rate;
·
Healthy materials that don't emit harmful substances
to our health;
·
Abundant use of wood (ecological reference material);
·
No use of harmful materials for the environment.
