DCC Policy / Documents
SI14 That all proposed developments be district
heating enabled in order to provide an environmentally
sustainable source of heating and cooling.
4.14.2 [B] Design of the Building
Building design will be required to comply with criteria
in the following key areas:
Thermal energy and integration into a District Heating
Scheme
IU9 That all proposed developments of an appropriate
scale be district heating-enabled in order to provide an
environmentally sustainable option for heating and
cooling
IU10 To investigate the feasibility of providing a district
heating boiler station in the eastern/industrial portion of
the SDZ area
It is the policy of Dublin City Council
SI62 To support the development of energy efficient
initiatives such as the district-heating network for
Dublin and combined heat and power.
SI63 To promote the use of Combined Heat and Power
in large developments
It is an Objective of Dublin City Council:
CCO9: To encourage the production of energy from
renewable sources, such as ….. combined heat and
power (CHP), heat energy distribution such as district
heating/cooling systems, and any other renewable
energy sources……..
SIO33: To support the development of energy efficient
initiatives such as use of District Heating and
Combined Heat and Power, and to promote the use of
CHP in large developments.
National Policy /
Documents(published by Government
on 16th February 2018)
• Support New initiatives in District Heating (such as the Dublin
Docklands ‘ District Heating Scheme) in cities and large towns
with a leading role for State bodies, for example, Gas Networks
Ireland, and Local Authorities.
• Establish a Climate Action Fund of €500 million under the
Department of Communications Climate Action and Environment
Key future growth enablers for Dublin include:
• Improving sustainability in terms of energy, waste and water, to
include district heating and water conservation;
• Improving sustainability in terms of energy, waste management
and resource efficiency and water, to include district heating
and water conservation.

GEO-URBAN ProjectAim
The overall objective of GEO-URBAN is to identify the geothermal resources available in two challenging
urban locations and to demonstrate a commercialisation strategy that has the potential to be adapted in
other similar locations.
