City of Dublin ETB's present Energy Efficiency metric measures Energy use (kWh) per square meter (m2) of the floor area of our buildings (kWh/m2). It is derived from the Total Primary Energy Requirement (TPER) as reported to The SEAI's Monitoring and Reporting Database (M&R).
Our baseline and latest available Energy Efficiency data is set out in the table below. The last row sets out the mandated 50% improvement in Energy Efficiency required by 20307.
| kWh/m2 | normalised % |
|---|
| 2009 Energy efficiency (Baseline): | 156.13 | 100 |
|---|
| 2022 Energy efficiency (Latest M&R Data): | 131.53 | 84.24 |
|---|
| 2030 Target & Modelled Scenario | 78.01 | 50 |
|---|
The demand reduction required to achieve this improvement has been modelled within the SEAI "gap to target tool" and the graphical extract below (normalised) demonstrates the achievement of the target (red dotted line).
The modelled Energy Efficiency scenario represented above traces the exact same path as that modelled for the required CO2 reductions. These measures are tabulated in Appendix A for Scope 1 emissions and in appendix B for Scope 2 emissions.
It should be noted that having modelled the scenarios set out clearly in the 2 appendices, a significant gap to the efficiency target remained to be bridged. This remaining gap was quantified and modelled as a package of combined further demand reduction and the quantified and modelled efficiency scenario is set out in appendix E.8
