DCC Policy / Documents
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
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
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.
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
