Energy Master Plan

Energy Master Plan

Our Energy Master Plan  (EMP) provides a framework for the transition to reduced energy usage and a low carbon future for Portmarnock.  The cost of preparing the EMP was covered by a grant provided by SEAI and it was prepared on our behalf by IHER Energy Services.

Key components of the EMP are: 

  • Assessment of the Current Energy Consumption of Portmarnock
  • Energy Audits of typical homes and public buildings In Portmarnock
  • Register of Opportunities which identifies potential projects and actions with measurable targets for reduction in energy usage

The full Energy Master Plan can be read by clicking below but these are some of the highlights.


BER Database Analysis

BER Database Analysis

Section 2 of the EMP contains an analysis of housing in Portmarnock based on BER data with breakdowns of housing under headings including age, type, wall type and insulation and heating type.

Current Energy Consumption

Current Energy Consumption

The assessment of our Current Energy Consumption gave a baseline for our energy usage summarised in the EMP.
The total estimated annual spend on energy was €17 million so food for thought there particularly as energy costs have risen since the EMP was prepared and are continuing to rise.

Column 1 CO2 (tonnes) Total (kWh) Energy Cost
Residential 25,913 96,472,502 €7,446,580
Non-residential 4,092 16,195,267 €1,167,040
Transport 13,336 57,008,436 €8,350,000
Total 43,341 169,676,205 €16,963,620

We spend nearly €17 million a year on energy

Home Energy Audits

Home Energy Audits

Energy audits were carried out on 8 home types in Portmarnock based on 8 of the most common house types in Portmarnock. 

Location Type Year
Carrick Court semi-detached 1974
Limetree Avenue semi-detached 1972
Carrickhill Heights detached 1975
Portmarnock Drive detached 1972
Wheatfield Road detached 1972
The Dunes detached 1973
Strandmill Road Terraced 1976
St. Anne’s Square Terraced 1962

The energy audit process involved the following 

  • BER survey on each house 
  • Energy retrofit analysis with 3 levels of retrofit packages assessed in each case.  
  • Retrofit calculator sheet showing the results of the analysis and giving costs of retrofitting, energy savings and payback time.  
  • Descriptive brochure for each of the eight house types with key results from the retrofit analysis.  

The three retrofit packages were as follows:


Includes lower cost measures such as

  • Increasing attic insulation to 300mm
  • Cavity wall insulation (where applicable)
  • A heating controls upgrade:
  • Installation of low energy lights


Adds further measures to the starter package such as

  • Internal or external wall insulation (whichever is applicable)
  • A condensing boiler 
  • New double-glazed windows & new doors
  • A wood burning stove to replace an open fire


Adds further measures again to the standard package such as

  • Insulate other roof types (sloped and/or flat roofs)
  • Insulate suspended timber floors where present
  • Upgrade windows to triple glazing and install high specification doors
  • Address any air-tightness issues and install a demand control ventilation system for improved air quality
  • Install an air-source heat pump rather than a gas boiler to deliver space heating and hot water. 

Public Building Energy Audits

Energy audits were conducted on four public buildings:

  • Portmarnock Sports and Leisure Centre
  • Portmarnock AFC
  • St. Helen’s National School
  • Portmarnock Golf Club

A separate report was produced for each building with a range of improvements recommended.

Register of Opportunities

The Register of Opportunities is our basis for planning our future work and contains the specific energy efficiency measures identified in the home energy audits and the measures recommended in the public building audits. It also contains key opportunities proposed by the PSEC in our review of wider energy reduction opportunities.

The Register of Opportunities is based on ambitious targets of 4% annual energy reduction target for residential buildings and for commercial and public buildings and a 3% reduction in transport energy use per annum. Achieving these targets would give a net overall reduction of energy usage in Portmarnock from 169.68 GWh to 119.94 GWh, a reduction of 31%.


Looking for a simple introduction to Retrofit Measures & Technologies?

The final section of the EMP gives some basic information on various retrofit measures and technologies, including insulation, heat pumps and solar voltaic panels, for anyone who wants a quick introduction to retrofitting.
