The first speaker was Mr. Edwin Ginn (Sr. Scientific Officer, Climate Change and Climate Forecasting Division – Hong Kong Observatory) and his topic was “Global Climate Change, its Impacts and Relevance to Hong Kong”.
Mr. Ginn stated Climate Change is the most important issue in the 21st century. Further, he explained the different between climate and weather (i.e. Climate is what you expect; Weather is what you get). Then he showed many scientific evidences and demonstrated how critical it was!
There are three observations of global changes:
i) Rise in mean surface temperature
ii) Rise in global mean sea level
iii) Decrease in Northern Hemisphere snow cover
The concentration of CO2 has been increased significantly which can be demonstrated in different locations, e.g. West China.
The second speaker was Ir. Colin Chung (Executive Director, Parsons Brinckerhoff (Asia) Limited) and his topic was “Green Design for Reducing Carbon Emission”.
Mr. Chung indicated the amount of Hong Kong Green House Gases (GHGs) (44.8 Million Tonnes CO2 generated per year) and a comparison of CO2 generation with other countries.
He explained the characteristics of “A Low Carbon Emission Building”:
· Reduction in use of Fossil Fuels
· Reduction in Electricity & Energy Use
· Water Conservation and Re-use
· Adoption of Renewable Energy
· Waste Minimization and Avoidance
· Use of Recycle Building Materials
To have “Low Carbon Building Design”, Mr. Chung pointed out 4 factors that should be considered, namely “Building Orientation”, “Building Form/Geometry”, “Building Envelope” and “External Shading”.
Finally, he concluded his speech by encouraging people to design low carbon emission buildings so as to reduce carbon footprint. Act Now or it’s too late!
Then the third speaker, Ms. Connie Sham (Sr. Manager, HKQAA), presented “Carbon Audit”.
In addition, Connie shared the main steps to do a Carbon Audit.
1. Define Organizational Boundary (It separated into two approaches: Management Control Approach and Equity Share Approach.)
2. Define Geographical Boundary (e.g. site boundaries of building)
3. Establish base year (data collected by Single base year / Average of several year / Rolling base year)
4. Define Operational Boundary (e.g. specific activities emit GHG)
5. Identify GHG Sources
6. Choosing Calculation Methodology (It separated into two approaches: Calculation-based approach and Measurement-based approach.)
7. Choosing Emission Factor (EF) & Global Warming Potential (GWP)
8. Collect Data
9. Calculate Emission
10. Develop GHG Inventory (example: Connie Pizza & Noodle Shop)
11. Reporting (including “Total GHG Emissions”, “Carbon value per employee (per job/project/dept.)” and “Power used per square foot (offices)”)
She affirmed the GHG target can be a planning tool to drive GHG reduction and showed some famous companies target such as Polaroid, Shell, Intel and CLP. Moreover, she indicated the improvement action by “GHG Removal”.
He agreed Connie that the immediate action for carbon reduction is “Carbon Audit”. Besides, “Carbon Trading” and “Clean Development Mechanism – CDM” are also important.
He summarized several institutional hurdles (barriers) as follows:
· Traditions, established practices and designs
· Market structure and condition may not encourage adoption of innovative products
i) Change has to be driven by management.
ii) Legislation for Mandatory Building Energy Code will help alleviate the second hurdle.
iii) Entrepreneurs to put in greater investment in manufacturing of energy saving equipment and systems.
iv) Everybody needs to involve.
The fifth speaker, Mr. Henry Chan (President, The Hong Kong Institute of Housing), presented the topic “Green Practice in Property Management Industry”.
He believes that the success green property management should be supported by owner, tenant and management staff. The role of property management on green practice includes planning, persuading and analysis, as well as, implementation.
Examples are lighting, construction materials, etc.
The sixth speaker was Ir. Cary Chan (Head of Technical Services, Swire Properties Management Limited) and his topic entitled “Energy Saving vs Carbon Reduction, How Swire Properties Acts Differently”.
The Energy Management employs “knowledge base energy management approach”, by which all related data is analyzed using a precise computer system.
He ended with his experience on the way to change mindset from “Energy Audit” to “Carbon Audit”. They were:
· From Cost Saving to Carbon Reduction
· From I to We
· From Profit to Survive
· From Now to Future
· From Home to Earth
The seventh speaker was Mr. Yu Shuk Man (Head of Business Development – Engineering, Hong Yip Service Company Ltd.) and he presented “Environmental Policy in Property Management”.
i) Less water and electricity consumption
ii) Greenhouse gas reduction
iii) Waste reduction and recovery
He then introduced some measures that were employed in the property management such as solar power and wind energy. He said the trial application of renewable energy was for education purpose.
i) Green Policy
ii) Waste Management
iii) Energy conservation
iv) Air Quality Monitoring
v) Green Procurement Policy
vi) Green Education and Promotion
He showed the flow chart on conducting energy audit.
He concluded environmental property management can be success by enforcing environmental protection policy and active participation.
The eighth speaker was Mr. Fung (EMSD) and he presented “Buildings Energy Efficiency Funding Schemes under Environment and Conservation Fund”.
Environment and Conservation Fund reserved HK$450 million to mobilize the public to take concrete actions to enhance buildings energy efficiency through two projects.
The energy-cum-carbon audit projects and the energy efficiency projects were subsidized HK$150 million and HK$300 million, respectively.
Lastly, Ms. Connie Sham (Sr. Manager, HKQAA) presented another topic entitled “Carbon Reduction Labeling – A Pledge for Achieving Carbon Zero”.
She pointed out some benefits by applying the scheme such as demonstration of organization commitment to environmental responsibility, towards carbon neutral, reduce GHG emission, etc.
The second question is how to influence tenant to participate the energy saving program? According to Mr. Cary Chan, Australia professionals tried to use Green List but the result was not significant. It can’t help but promotion of energy audit / carbon audit to tenant.
