Sustainable Buildings
„
ACCIONA has constructed over 1,100 eco-efficient homes, and has built the first Zero
Emissions commercial building in Spain.
„
Sustainable infrastructure addresses economic, social and environmental factors.
z Environmental – CO2 emissions, waste management, water and energy usage, and
materials selection.
z Economic – energy, maintenance, and repair costs.
z Social – interior air quality, accessibility, living quality, and external integration
with surroundings.
z During construction, avoids toxic materials and pollutants, and optimize energy and
water use.
„
Homes have more efficient water consumption and cost less to run. Buildings consume
half the usual energy, covering all energy demands with solar and biomass renewable
sources.
„
ACCIONA is leading the Energy Efficient Buildings Association (E2B) formed to represent
the interests of private industry in Europe, defining the strategic research agenda for
energy efficient buildings and districts. The founding members are ACCIONA, Arup,
Bouygues, D’Appolonia, EDF, Mostostal, Phillips, Saint-Gobain and Stiebel-Eltron

Desired CO2 balance
Projects are analyzed to optimize the final design. Less costly measures
are studied first, so that the use of expensive equipment is reserved as a
last resort:
„ Building architecture is reviewed and modified to
reduce energy consumption (incl. heating, cooling,
ventilation and lighting)
„ The most efficient solutions for energy production
and distribution are applied
„ Renewable energies are used to minimize
emissions

Conserve Energy
The compact cubic shape of the building reduces energy
losses and atrium provides lots of natural light.
„ NORTH façade, with smaller
size glass enclosure. Lower
energy losses but with an input
of natural light.
„ SOUTH façade built as a
glasshouse and curtain wall, with
large windows and photovoltaic
modules in the form of parasols.
„ EAST facade with smaller glass
enclosure to avoid excessive
heat in summer, but with an
input of natural light.
„ WEST facade without glass
enclosure to avoid excessive
heat in the summer.

Pioneers in development and sustainability
Sustainable Edification: Sant Cugat
„
ACCIONA is currently working with the town of Sant
Cugat, a suburb of Barcelona, to develop a zeroemission neighborhood.
„
Sant Cugat plans to offer approximately 150 units as
affordable rental housing for young people, as well as
a technology-focused high school.
„
The study will analyze passive measures to decrease
building energy requirements by 30-50%. Simulation
tools will be used to study insulation levels, shadowing,
facade construction and types of glass.
„
Neighborhood will cover all its remaining energy needs
from renewable sources - solar and biomass.
― Thin film PV panels on rooftops: installed power 100
kWp
― Biomass fuel will be waste from nearby towns
› Trigeneration using Stirling engines
› Installed power 60 kWe, 400 kWth

Efficient Building Design: Sant Cugat
„
The roofdeck will be oriented to maximize photovoltaic production, and the buildings
will have a slim design to benefit from natural cross ventilation.
„
Pilot project will test the latest technologies in intelligent metering, in collaboration
with MIT, in order to promote energy consciousness and saving.
„
Urban planning will promote better interaction of the neighborhood to further reduce
energy requirements.
