EN3: Direct energy use segmented by primary source-building energy use (TLP)

Goals 2005-06

Continue process of meter upgrades to improve electricity consumption reporting
Further decrease tenant light and power (TLP) consumption to 4500MJ per person per year by 2005-06

Performance 2005-06 and trends

overall tenant light and power (TLP) consumption in our JGB/EBB tenancies totalled 1 782 875kWh, up 6% on last year. This amounts to 6418GJ
JGB accounted for 87% of the total usage
on a per person basis, our consumption was 5376 MJ/person/annum, over 45% below the Australian Government’s target of 10 000 MJ/person/annum, but above the 5000MJ goal set for 2005-06
an increase of 4% in annual consumption per m² of office space occurred, to 266 MJ/m²/year
100% of the JGB electricity needs continued to be met with accredited green power. With the increase in use of the EBB tenancy, our percentage of overall power needs being met with green power dropped to 87%, similar to 2001-02 levels
securing green power supply for the EBB tenancy has proved to be difficult due to our current lease arrangements, however, it continues to be pursued for this and other tenancies
metering within JGB was improved to allow for more accurate data capture
the Fyshwick warehouse facility used 43 149kWh. We will report on trend data for this building in the future.

Electricity costs by location were approximately $240 000 for JGB, $25 000 for EBB, and $6000 for the Fyshwick warehouse.

Table 1: Tenant light and power consumption
Tenant light and power	2001-02	2002-03	2003-04	2004-05	2005-06	change
Total kWh	1 710 786	1 389 809	1 448 335	1 687 601	1 782 875	6%
Total GJ	6159	5003	5214	6075	6418	6%
MJ/person/year	5618	5158	5500	5233	5376	3%
MJ/m²/year	338	292	274	255	266	4%
% green power	86%	82%	93%	97%	87%	-10%

These figures are totals for the JGB and EBB office tenancies. 2004-05 per person figures were incorrect and have been corrected.

Commentary

The use of electricity generated by combusting fossil fuels results in greenhouse gas emissions that contribute to global warming, and consumes non-renewable natural resources. The Australian Government Energy Policy addresses these concerns by requiring all Departments and Agencies to achieve a consumption rate of less than 10 000 MJ/person/year for TLP. A new target of 7 500 will be set in the near future, providing a fresh challenge for all Australian Government Departments.

Goals 2006-07

Reduce TLP intensity to 5 000 MJ/person/annum for office tenancies by 2007-08, one-third below the new Energy Efficiency in Government Operations (EEGO) policy target
Conduct a full energy performance audit of the JGB and EBB office tenancies
Gather and report on trend statistics for non-office space DEH tenancies within the ACT, including all warehouse and storage facilities.
