The annex on Solar Thermal Energy Capture
in the general environmental ordinance of the Barcelona
City Council went into force in August 2000 for the
purpose of regulating the incorporation of solar thermal
energy capture and use systems for the production
of sanitary hot water in the city’s buildings.
The Solar Ordinance affects newly built, rehabilitated and
fully reformed buildings and those seeking to implement a
change of use, with a forecasted volume of sanitary hot water
demand equal to an average annual energy consumption of over
292 net megajoules (MJ).
This regulation applies to buildings
intended for residential, health-care, sports, commercial
and industrial use and, generally,
any activity involving the existence of dining rooms, kitchens,
laundries or other circumstances that lead to a large consumption
of hot water.
The monitoring and
assessment of the development of the Solar
Thermal Ordinance is one of the projects of the Barcelona
Energy Plan, which the Barcelona Energy Agency has
been managing since May 2003 through an agreement with
the Barcelona City Council.
The Barcelona Energy Agency is preparing a new text of
the Ordinance with a lower threshold of application in
order to make it applicable to almost all the city’s
new and rehabilitated buildings. With the aim to achieve
the maximum consensus for its development, the Barcelona
Solar Energy Bureau has been formed. All the stakeholders
involved in the application of the rules and the implementation
of solar energy in general in the city are represented
in this body.
The Barcelona Energy Agency has published a
Guide to Solar Thermal Energy Facilities, using an easily-understood
and graphic resources to make known the characteristics of
solar thermal technology and the positive effects to be derived
from its use.
