I would like you to ask for helping me with one LEED issue. We were doing energy model and we have received comments to our model, which one of them is this one:
8. Table 1.4.8 indicates that the Baseline model includes two screw chillers; however, the Baseline model must include at least two equally sized centrifugal chillers, as required by Table G18.104.22.168, since the building peak cooling load is greater than 600 tons (2,551 kW), as indicated in Table 1.4.8. Revise the Baseline model to include at least two equally sized centrifugal chillers. In addition, ensure that the efficiency of each centrifugal chiller is based on the autosized cooling capacity of each chiller using Table 6.8.1C (6.1 COP). Furthermore, update Table 1.4.8 reflecting the changes.
I don´t understand the fact ,, ...since the building peak cooling load is greater than 600 tons (2,551 kW), as indicated in Table 1.4.8. ...''. When I look at our Table 1.4.8., there is no 2551 kW but 1874 kW (total chiller capacity). Could you help me, how I should understand this comment and solve the problem. I really don´t know what to do with it.
Thank you in advance,
