For the purpose of assessment of this credit, the baseline air-
conditioning shall have identical zoning to the designed building, but
shall be modeled with a system and equipment as described in the
following table:

Reference shall be made to the latest BEC on the performance of
individual components of the systems.
*For buildings with area less than 20,000 sqm – 2 water-cooled screw
chillers sized equally, for buildings with area more than 20,000 sqm – 2
water cooled centrifugal chillers minimum with chillers added so that no
chiller is larger than 2800 kW, all sized equally.
Baseline Envelope Design
Also, in A3.3.2 (d) of BEC, concerning building envelope:
“For buildings not governed by the OTTV requirements, the dimensions
of the windows, doors and skylights shall be the same as the designed
building”
Again, for the purpose of the assessment of this credit, in the case of
buildings not governed by the OTTV requirements, the baseline building
envelope need not be the same as the designed building, instead
suggested baseline envelope specifications are given in Appendix 8.2.
