Since July 2000, the Barcelona City Council
has implemented a law concerning the
use of solar energy. According to this «solar
by law», all new buildings as well as
those subject to general refurbishment, are
obliged to use solar energy for 60% of
their sanitary hot water supplies.
Moreover, the Universal Forum «Barcelona
2004» is being planned, which will
take place at the seafront of the Besos
municipality. For this reason, a significant
renovation and remodelling of the Besos
seafront is foreseen in the master plan as
well as in the infrastructure development
plan. These changes will entail considerable
building work over the next few years.
The urban renovation and reconstruction
of this community provide an excellent opportunity
to apply the principles of sustainable
development. The Renewable Energy
Partnership «Barcelona Renovable
2004» is being founded with this in mind,
and with special emphasis on the energy
cycle. Its general objectives are the application
of renewable energies as well as
energy efficiency measures, and reducing
the environmental impact of the use of energy.
Main aims
The urban renovation and reconstruction
of this territory offer an excellent opportunity
for application of the principles of
sustainable development. The Renewable
Energy Partnership “BARCELONA
RENOVABLE 2004” is being founded
with this idea, and with a special emphasis
on the issue of energy cycle. Its general
objectives are the following:
Promote the application of Renewable
Energies.
Promote the measures for the efficient
use of energy.
Reduce the impact on the environment
caused by the use of energy.
Objectives
The «Barcelona Renovable 2004» initiative
puts forward several specific propositions
that should be attained by the beginning
of 2004, such as:
1.35 / 4.5 MWp of photovoltaic systems,
10,000 m 2 of solar thermal collectors,
district heating (25 MWt) and district
cooling (30 MW c) from thermal solar
energy and waste energy,
50 apartments with biomass heating,
bioclimatic architecture in urban planning
and building design,
a community which is moving towards
100% renewable energy supply.
Project details
Three energy measures foreseen initially:
PV central
District heating &cooling system
Energy efficient buildings
Besides this three energy measures foreseen
initially, the new one is added: biogas
digestors are being constructed within the
same site. Biogas is going to be used for
CHP.
PV fields on the site: Under initial planning
the station has been divided into two
units: the main pergola of around 1 MW
and an additional installation of 150 kWp.
First phase (main pergola) is going to be
finished in February 2004. Second phase
building October 2004 – March 2005.
District heating cooling system. The proposed
DHC operation is based on the utilization
of the TERSA’s plant steam. 30 ton/
h at 8 barg, 5ºC reheating are put in order
to reach wep steam in the DHC central. An
energy transference plant composed by heat
exchanger water/water, a system of energy
measurement and a control regulation system
will be in each building. Along the primary
unit mentioned before the water will
be driven from the DHC heat plant to the
secondary unit transferring the enough
energy to satisfy the demand. The control
system of the heat plant will allow to
optimise its functioning, so much from the
energy point of view as of the point of view
of operation and maintenance. The system
will allow also the monitoring and energy
bill control in each building.
Bio Climatic Criterions – Applications &
Control: The main topics proposed to be
regulated are:
Energy efficiency
Implantation of renewable sources
The measures related to the energy efficiency
are the following ones:
Limit of the energy demand for building
climatization.
Lighting of buildings.
Efficiency of the building air conditioning
systems
The measure related to renewable
sources:
Power generations systems by means of
the Photovoltaic facilities
Thermal energy generations systems by
means of the Thermal solar installations
Enabling factors
The network connected PV systems benefits
from the Spanish feed-in law, so they
generate incomes. The installations bigger
than 5kWp the price for each kWh generated
and sold to the public network is
0,22 Euro/kWh.
Challenges
Currently, the exigency degree of the PV
installations is the main doubt in the normative
due to the prices of this technology.
Nevertheless, the PV costs tendency is to
decrease gradually. The consulting service
focused on advices on the PV market and
the possibilities to obtain subsides could
help the building developers to fulfil this
criteria.
