3. Efficient vertical transportation system in common areas.
The requirements for these are addressed subsequently.
8.8.2.1 HVAC System
in Common
Area
Energy simulation will be required to show that the carbon emissions or energy
consumption of the building is less than a respectively benchmark criteria
evaluated from a baseline building model for mechanical ventilation systems.
Methodology of the energy simulation of the baseline model and the proposed
model shall make reference to EU 1 – Reduction of CO
2
emission & Appendix
8.1/8.2.
If a hybrid ventilation system is adopted, an exceptional calculation
methodology shall be conducted (see EU 1 – Reduction of CO
2
emission &
Appendix 8.1/8.2).
If natural ventilation is adopted in common areas, the reduction in the energy
consumption of the HVAC System can be assessed based on the area of the
location where natural ventilation is applicable. The calculation or simulation will
be required to demonstrate that natural ventilation can provide adequate indoor
comfort conditions.
8.8.2.2 Artificial
Lighting System
in Common
Area
Energy simulation will be required to show that the carbon emissions or energy
consumption of the designed building compared to a baseline model. The
methodology for the energy simulation of the baseline model and the proposed
model shall make reference EU 1 – Reduction of CO
2
emission & Appendix
8.1/8.2.
Note that car park is excluded from this assessment as energy consumption of
ventilation system of car park is assessed by EU 4.
8.8.2.3 Vertical
Transportation
in Common
Area
The EMSD’s Building Energy Codes 2012[ 9] sets out requirements for the
efficiency of vertical transport. To achieve the credits, buildings have to exceed
the requirements of the building energy codes 2012.
