Synergy Energy Efficiency Index (HK) - Commercial Sector: 117%
The score of Intensity Effect is rebased at 100% in the year of 2000 so that it acts as a gage to Hong Kong’s relative increase in energy use (the percentage of change in energy consumption for the exact same activity) since that date.
In other words, a score of index is 100% reflects that Hong Kong is just as efficient now as in 2000. While a score of 80% would indicate that Hong Kong is 20% more efficient than before and a score of Index 130% would show that Hong Kong wastes 30% more energy to perform the same activity 14 years after the base year.
To Conclude: Based on this year's analysis, the Index score of Commercial Sector is 117%. By using 2000 as a base year, the index has revealed that 17% more energy was consumed compared to the past when performing the same activity in commercial sector over the last decade (2000-2014).

|Floor area ('000 m2) / Year||2000||2010||2013||2014|
Table 6: Energy Consumption by segment by years
|Energy Use (TJ) / Year||2000||2010||2013||2014|
The Commercial Sector covers the segments of Office, Restaurant, Retail and Others. The entire energy consumption in TJ of office and restaurant has decreased in 2013 compared to that of 2000 regardless of the total floor areas of these two segments have increased. The significant percentage of increases in energy consumption are found in Others.
The other miscellaneous refers to the segments, such as Hotel, University Campuses, Data Centre, Hospital, Warehouse Storage and Commercial and Public Services, which were contributing to the growth in energy consumption to the entire commercial sector.

|ÄExk (2000, 2014)||Activity||Structure||Intensity||Weather||Total Effect|
Based on the above table with negative figures shown in Intensity column, the energy efficiency performance of both office, restaurant and retail has improved over the years respectively.
Isolating the effect in the growth of the number of offices, retail stores as well as restaurants, which resulted in an increases in total floor areas, the significant surge in net Intensity Effect (energy consumption) could be explained by the rapid expansion in energy consumption of Others.
