Hotel energy performance in 2013
To track the hotels’ intrinsic energy performance, the indicator used
is kWh per available room, which is in standard use across the
industry, thereby enabling us to compare and assess our performance.
All of the owned, leased and managed hotels track their monthly
the OPEN application. At year-end, after stripping
out hotels acquired or sold over the year and hotels that failed to
report data for all twelve months, the data are reviewed and validated
internally. In 2013, this process resulted in the consolidation and
analysis of 87% of hotel data, a response rate that has risen steadily
year after year (72% in 2011).

Initial analyses show that energy use in the consolidated scope of
reporting, as expressed in kWh per available room, steadily increased
over the 2011-2013 period, by a total 6.7%.
Nevertheless, the increase does not intrinsically reflect our energy
performance due to the significant variations in the scope of
reporting over the period, which accounted for 90% of the rise.
These variations are of two types:
first, the scope of reporting was impacted by hotel disposals
and acquisitions, which totaled more than 700 units over the
three-year period. A large percentage of new openings were
in regions or brand segments where energy use is inherently
less efficient (due to larger or more luxurious rooms, better
equipped facilities, more systematic presence of spas, etc.).
This factor automatically increases the average energy ratio. For
example, half of all hotel openings in 2013 were in Asia and more
than half of the recently opened hotels were in the Midscale
and Upscale segments;
second, the quality of reported data has improved over the years.
For example, in the case of 30% of hotels, data were validated by
the internal control process in 2013 that were not validated in 2011.
As a result, only the energy ratios at comparable scope of reporting
in 2011, 2012 and 2013 offer a meaningful vision of Accor’s actual
energy management performance over the period.This information
has been added to the chart above, where energy use data are
presented for the same base of 1,061 hotels over the three years.
At this comparable scope, energy used (in kWh per available room)
edged up by just 0.3% between 2011 and 2013, reflecting a 2.4%
increase in 2012 and an 18% decline in 2013.
If the ratio is also adjusted for such parameters as weather conditions
and occupancy rates, which have a significant, demonstrated
influence on energy performance, the adjusted ratio of kWh per
available room declined by around 2.9% over the three-years
is most accurate figure for expressing Accor’s intrinsic performance
in managing its energy use.
While, in the end, Accor’s energy use is intrinsically trending
downwards, it is still not on track to meet the 10% reduction targeted
for 2015. We are therefore going to continue deploying dedicated
programs to improve and optimize energy management in the
hotels, such as the BOOST method for optimizing the management
of utility installations.
Actions to manage energy performance in hotel
Charter 21, which supports the operational deployment of the
corporate sustainable development strategy in the hotels, also
recommends a wide range of actions to improve the energy
performance of everyday hotel operations (
bulbs for round-the-clock or room lighting, installing energy-efficient
(1) Based on data from 900 of the 1,061 hotels in the comparable scope of reporting, weather conditions and occupancy rates increased the energy
ratio year-on-year by 1.4% in 2012 and 1.8% in 2013.
