9 BEEO Regulation Framework Cap Buildings Energy Efficiency Ordinance (BEEO) Cap 610A Buildings Energy Efficiency (Fees) Regulation Cap 610B Buildings Energy Efficiency (Registered Energy Assessors) Regulation Building Energy Code (BEC) Energy Audit Code (EAC) 9

10 Milestone of the BEEO HK Energy Efficiency Registration Scheme for Buildings (Voluntary Basis) BEEO was published in gazette BEC BEEO came into full operation 10

11 Framework of the Ordinance Energy Efficiency Standards Energy Audit Hotel & guesthouse Commercial building Commercial building Educational building Industrial building Community building common area Municipal services Residential building common area Hospital & clinic Government building Composite building Airport passenger building Railway station commercial portion common area of portion for residential or industrial use Composite building commercial portion 11

12 BEEO The 3 Major Requirements (1) Newly constructed buildings Obtain Certificate of Compliance Registration (COCR) from EMSD (2) Major retrofitting works in existing buildings Obtain Form of Compliance (FOC) from REA (3) Energy Audit in commercial buildings Identify Energy Management Opportunities (EMO) and Energy Utilization Index (EUI) 12

13 (1) Newly Constructed Buildings Stage One Declaration Developer engage Registered Energy Assessor (REA) to submit declaration 2 months after obtaining consent to commencement of building works ( 開工紙 ) To declare the design of major building services installation to comply with the BEC Stage Two Declaration Developer engage REA to submits declaration 4 months after the Occupation Permit ( 完工紙 ) is issued. To confirm the energy efficiency requirements complying BEC 13

14 (2) Major retrofitting works in existing buildings Works Area Addition/replacement of a BS installation: Central BS installation (CBSI) Addition/replacement of main component: total floor area covered by the works (i.e. works area) 500 m² in a unit or a common area OR electrical circuit 400A A/C installation 350kW motor drive + mechanical drive Completion of works Inspection by REA Declaration in submission Issue Form of Compliance (FOC) 14 2 months

15 (3) Energy Audit From Registered Energy Assessor (REA) Energy Audit Report with Energy Utilization Index (kwh/m 2 /annum) Energy Audit Form To be exhibited at building main entrance 15 EMO - Cat 1 - Cat 2 - Cat 3 Identification of Energy Management Opportunities (EMO) for consideration of client department

16 Building CBSI (built-in equipment) Lighting Installation Air-conditioning Installation Electrical Installation Lift and Escalator Installation 16

17 Lighting Installation Key Update on BEC Tighten the LPD requirement (W/m 2 ) 2. New Requirement on Automatic Lighting Control Lower the curtain or insufficient sunlight Occupant Sensing Control Daylight Responsive Control 17

18 Electrical Installation Key Update on BEC Upgrade the motor efficiency (IEC Motor) 2. Separate metering device for major BSI (e.g. chiller plant, heat pump plant, lift and escalators) 18

19 Air-conditioning Installation Key Update on BEC Tighten the Coefficient of Performance (CoP) 2. Introduction of chiller part load performance Air-conditioning Installation 3. Adoption of Variable speed drive 4. Provision of demand control ventilation 19

20 Lift & Escalator Installation Key Update on BEC Max. allowable power 3 ~ 5 % Declaration load 2 % 2. Lift Regeneration Braking 20

21 Lift & Escalator Installation Key Update on BEC2015 Demand Control Escalator Automatic Speed Reduction 21

22 BEEO Achievement Over 1,300 building declared to follow BEC Around 400 buildings with COCR Over 4,000 FOC for MRW Over 3,000 commercial buildings meet the energy audit requirements The saving of 5 billion kwh for newly constructed buildings up to
