[1] Offices in QGO and APB Centre represent 94% of total ArchSD office space.

[2] Territory wide default GHG emission factors were used based on the Guidelines to Account for and Report on Greenhouse Gas Emissions and Removals for buildings (Commercial, Residential or Institutional Purpose) in Hong Kong issued by the Environmental Protection Department, HKSAR in July 2008. Previous data were adjusted accordingly.

[3] Energy efficient installations refer to LED Exit sign, occupancy sensor/ photo sensor, water-cooled chiller/ evaporative cooling tower etc.

[4] A revised baseline for calculating the estimated energy saved was adopted in 2007 by taking into the account of the requirements of the BEC 2007 Edition and also the technological development. Direct comparison of data before and after 2007 is therefore inappropriate.

[5] Saving would mostly be harvested from the medium or large-scaled projects. In 2008, large numbers of relatively small-scaled projects, like schools, open spaces, toilets were completed and their contributing savings were comparatively small. In particular, the saving comparison benchmark in reference to (EMSD's BEC 2007 Edition) has been raised up since 2007, the savings would be deemed lower.

Resource Usage - Fuel

  Units 2008 2007 2006 2005 2004

GHG emission equivalent to fuel consumption by ArchSD pool cars [6] Tonnes CO2e 39.8 50.6 53.2 65.4 N/A

[6] GHG emission factors for mobile combustion are based on the Guidelines to Account for and Report on Greenhouse Gas Emissions and Removals for buildings (Commercial, Residential or Institutional Purpose) in Hong Kong issued by the Environmental Protection Department, HKSAR in July 2008. The GHG figures for 2005, 2006 & 2007 have been restated from 57.1, 46.4 and 44.1 respectively, as given in the previous Sustainability Report.

[7] The normalised ratio is an indication of the extent ArchSD has improved in an area after taking into account the changes in contract value each year, so as to facilitate better comparisons over time. Such data in 2004 & 2005 are re-adjusted due to incorporation of data from all contract works, also including works for maintenance and improvement.

Percentage of annual expenditure   10.3% 8.0% 7.1% 6.0% 5.2%

Considering all our refrigerants and fire extinguishing agents used during replacement are environmentally friendly models as well as the insignificant consumption amount, we will not report our non-ozone depleting substances consumption value in the future.
