Synergy Energy Efficiency Index (Hong Kong)

World Green Organisation (WGO) has announced the launch of the Synergy Energy Efficiency Index (Hong Kong) – (1) Residential and (2) Commercial in 2016 (SEEI). SEEI is developed in collaboration with the Department of Management Sciences of the City University of Hong Kong, and sponsored by Synergy Group Holdings International Ltd.

A scientific tool, Energy Efficiency Index has been developed to diagnose the symptoms of energy wastage in Residential and Commercial sectors. The trend in energy use over the last decade as well as the attitudinal changes in sectoral energy performance (consumption) should be revealed.

Synergy Energy Efficiency Index (HK)

Residential Sector: 104%

How to Interpret SEEI

The score of Intensity Effect is larger than 100% indicating that by 2014, the change in energy consumption for the exact same activity is larger compared to that of year 2000. The Residential Sector is comprised of four segments namely, Public, HASS (Housing Authority Subsidized Sale Flats Segment), Private and Others. Although the total energy consumption in TJ of four segments has increased, the Intensity Effect of all segments (except Others) have exhibited an increase over the years (2000 - 2014).

Is Residential Sector energy efficient ?

To Conclude: Based on this year's analysis, the Index score of Residential Sector is 104%. The index using 2000 as a base year, has revealed that 4% more energy was used compared to the past when performing the same activity in residential sector over the last decade (2000- 2014).

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.

How to Interpret the Index

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.

Is Commercial Sector energy efficient?

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). Compared to last year's score of 110% in Commercial Sector, both Retails and Others sectors in 2014 have made a significant contribution to the increase apart from the decrease in Restaurant and Office Sectors.
