
Energy efficiency measures
Behavioural change
Development of renewable energy technologies.
Energy Performance of Buildings Directive,2001
Parts F and L (NI) amended November 2006 reductions in energy use and CO2 emissions.
Further amendments 2008 in NI – must include RET.
Emissions

Kyoto, 1997 - United Nations Framework Convention on
Climate Change (UNFCCC). Now >160 countries.

Six “greenhouse gases”– CO2, CH4, NO, SF6, HFCs, PFCs.

EU25 CO2 emissions >8t per capita.


EU target – 8% reduction on 1990 levels by 2008-2012.
UK target – 12% cut in emissions by 2010 plus a further
commitment to a 20% cut.
Pressure on all sectors to cut emissions.



Basic aim to reduce emissions by 1% p.a. from 1999/2000.
May ’06 – Aim to make the NI government office estate carbon
neutral by 2015.
Funding for energy/C reduction measures



Budgets for energy rising sharply.
Central/regional grant funding measures.
Ring-fencing of energy-related savings.

Energy Management in N.I. Councils.
 Commitment varies from council to council – ranges from
a F/T energy officer, to simply recording the energy bills!
 Need to be able to identify opportunities (including
funding) for improvements and renewable installations.
 Consider the energy and carbon performances of future
council buildings at the design stage.


Reporting mechanisms for site monitoring and meter reads.
Ongoing energy audits and benchmarking – sites and major plant
including CHP. New developments to be low-energy.
Energy use matched to facilities operation.e.g by BMS.
Opportunities identified for installing energy-efficient plant and
equipment and controls e.g. run-back timers, 24/7 controls, working
in partnership with the Maintenance Supervisors.





Head office
Seven Towers LC
Ballykeel CC

Total carbon savings 350t p.a.
Gas-CHP will save a further 85 tonnes C and £60,000
per annum.
Landfill gas generation project.





Anaerobic conditions in landfill generate 45-60% methane.
Potent climate change driver (21x CO2eq).
Flare or utilise to generate electricity.
ROI has 21MWe of installed LFG generation = 85GWh,
with potential for 304MWe by 2020.
NI has potential for 177GWh of LFG generation.






1MW/Mt of waste – depends on age and conformation of site,
composition of waste, etc.
1MW:670m3 gas at 45% CH4.
GasSim analysis - Ballymacvea could generate ~1MWe.
Renewable tariff + NIROCs = revenue > £70/MWh
Grid capacity and connection: >0.5MW requires 33kV line.
Option for managed site.
Public Sector Restructuring.
“Reorganising can be a wonderful method for creating the
illusion of progress, while producing confusion, inefficiency,
and demoralisation”.
Petronius Arbiter




Review of Public Administration (RPA).
Reduction from 26 to seven NI “Super-Councils”.
Additional services, facilities and staff will put pressure on
energy spends.
Review needs to include an Energy Policy which will
produce effective energy management across the new
Councils.







Creation of more energy-efficient community facilities.
