Enhancing the transparency of energy data and benchmarks in commercial buildings by introducing Online Building Based Electricity Utilization Index Benchmarking Tool
Dated 18 July 2022
Energy Consumption in Hong Kong
(A graph shows "Buildings Consume over 90% of the City's Electricity")
| Building Type | Percentage |
|---|---|
| Commercial | 64.4% |
| Residential | 28.8% |
| Industrial | 6.8% |

Data Transparency and Benchmarks
To mobilise the community to take collective actions to conserve energy, we need to enhance the transparency of data and benchmarks. We plan to, through releasing energy data and introducing energy benchmarking tools, facilitate the comparison of building energy consumption performance and establish a two‐way partnership in carbon reduction.

Current BEEO Requirements
- Energy consumption of CBSI (Central Building Services Installation) over the past 36 months is required to submit.
- EAF (Energy Audit Form) is required to exhibit publicity.
- Commercial buildings and commercial portion of composite buildings are required for Energy Audit
Online Building Based Electricity Utilization Index Benchmarking Tool (Online Benchmarking Tool)
Benefit of whole Building Electricity Utilization Index:
- As an index for building owners to identify cost-effective energy upgrades, realize energy and cost savings benefits from those upgrades.
- As a driving force for building owners to apply energy saving opportunities improving building energy performance
- To develop a new on‐line benchmarking tool for whole buildings electricity consumption
Methodology of Building Based EUI Benchmarking Tools
Building Category
| Category | Major usage of Commercial Building |
|---|---|
| C1 | Office building |
| C2 | Retail Building |
| C3 | Mixed commercial development (IFA ≤ 25,000m2) |
| C4 | Mixed commercial development (IFA > 25,000m2) |
| C5 | Commercial Building without Central A/C |
