REDIT REQUIREMENT
(a) Commercial and Hotel Buildings,
1 to 15 credits for a reduction of CO
2
emissions or annual energy
consumption by:
3%, 5%, 7%, 9%, 11%, 14%, 17%, 20%, 23%, 26%, 29%, 33%, 37%,
41% and 45% respectively.
(b) Educational Buildings,
1 to 15 credits for reduction of CO
2
emissions or annual energy
consumption by:
3%, 4%, 5%, 6%, 7%, 9%, 11%, 13%, 15%, 17%, 19%, 21%, 24%, 27%
and 30% respectively.
(c) Residential Buildings,
1 to 15 credits for reduction of CO
2
emissions or annual energy
consumption by:
3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 16%, 18%
and 20% respectively.
(d) Other Building Types,
1 to 15 credits for reduction of CO
2
emissions or annual energy
consumption by:
1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 12%, 14%, 16%, 18% and
20% respectively.
A
SSESSMENT
The number of credits to be awarded will be determined with reference to
the percentage reduction of CO
2
emissions or annual energy
consumption of the assessed building relative to the respective
benchmark (zero-credit) criteria evaluated from the Baseline Building
model.
The calculation shall be done in terms of units of either CO
2
– kg or kWh
per year. A simple conversion factor shall be adopted with reference to
the Carbon Audit Guideline or default assumptions in Appendix 8.3. Full
building energy simulation including energy used for heating, cooling,
lighting, equipment, small power, etc shall be considered.
The methodology of the energy simulation will make reference to the
lates
t Building Energy Code (BEC)or Appendix G of ASHRAE 90.1-2007
or equivalent. (Note: As of interim measure before a Hong Kong
equivalent of Appendix G of ASHRAE 90.1-2007 is available, lighting
power density (LPD) in ASHRAE calculation shall use those parameters
in Code of Practice for Energy Efficiency of Building Services
Installation – 2012 Edition). Appendices 8.1 and 8.2 include the
assumptions for design parameters for Performance-based approach for
residential and other building types for reference.
