Engagement with Government and Industry

• Hong Kong’s buildings sector contribution to global carbon reduction

• Accelerating energy efficiency in Hong Kong’s existing buildings

• Encouraging green building rating across public / private sector clients

• Rejuvenation of old industrial buildings

• Preparation for the C40 Cities Conference (HK, November 2010)

HKGBCHKGBC’’ss focus focus –– the first yearthe first year

Continued development of BEAM Plus

• Expanded accreditation of BEAM Plus Practitioners and Assessors

• Tailored rating systems for different development types (domestic, districts, etc)

HK sorely needs a roadmap for energy efficiency in buildings!

Buildings Buildings -- which way should we go ?which way should we go ?

CODES & LABELINGbuilding codes to be enforced and tightened over timeobligatory energy labeling for all non-residential buildingsenergy audits to identify performance & prioritiseimprovementsregular inspections of building envelope / energy systemsseparate energy controls and charges for each unit in multi-occupied buildings

SUBSIDIES & PRICE SIGNALStax packages / subsidies high enough to stimulate the marketcharging structures to encourage lower energy use and on-site renewablescreative business models that overcome the first-cost hurdle (utilities, business, financial institutions)

INTEGRATED DESIGN & INNOVATIONgovernment authorities to introduce process incentives for developersdevelopers to restructure business / contract terms for early contractor involvementutilities & stakeholders & developers to work via integrated design teamssubsidies / other incentives for domestic energy-efficiency improvements

TECHNOLOGY FOR ENERGY SAVING BEHAVIOURgovernment support for R&D of effective energy-efficient technologiesefficient information / communication technology in new / refurbished buildingsimprove energy / savings information to each customer from utilities

WORKFORCE CAPACITY FOR ENERGY SAVINGenergy efficiency training / vocational programs for all building workers and stakeholdersdevelop a ”system integrator” profession to support retrofitting in residential properties

MOBILIZE AN ENERGY-AWARE CULTUREsustained energy awareness campaigns by business / governmentbusiness & government to demonstrate leadership in their own buildings

Some ideas: WBCSD “EEB – Transforming the Market”

• 0.037 Million tonnes CO2e or 0.25% reduction in carbon emissions if

applied to new buildings only

• 2.98 Million tonnes CO2e or 20% reduction in carbon emissions if applied to

all new and existing buildings

• Current situation

– $450 Million allocated under ECF

– $76 Million approved

– 33,100 tonnes of CO2e savings

• How much to completely retrofit all buildings?

• How much to reach 45% intensity reduction (1M – 3M tonnes from buildings) or 2 deg limit (3M to 6M tonnes from buildings)?

The The BEAM PlusBEAM Plus green building labelgreen building label

Nov 2009:12.00am

Providing BEAM qualifications to industry professionals help facilitate the wider take-

up on green building practices appropriate to Hong Kong

• Training for professionals to enhance knowledge on building sustainability issues in Hong

Kong and how BEAM addresses these (announcement this May)

• Examination to distinguish professionals with the knowledge to facilitate the BEAM

assessment process and advise on design, construction and management, etc

• Bring BEAM Plus inline with other green building label schemes overseas and keep pace

with the rapid expansion of HK’s green building industry

Scheduled Training Courses:

• 20th April 2010

• 12th May 2010

• 4th June 2010 (Certificate Presentation Ceremony / Testing & Commissioning Workshop)

• 9th June 2010

• Mandatory BEC’s a step in the right direction but by no means on their own a silver bullet for our energy / climate change challenges

• Progressive tightening of standards required

• Actions need to be placed in the broader context of a carbon budget for Hong Kong

• Systems that are efficiently designed and installed are not necessarily efficiently used!!!

• Let’s not forget the wider opportunities for energy saving at the neighbourhood vsbuilding level – district cooling, “carbon balancing” etc
