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.
