This drawing is for the HVAC roof layout of a mosque, including FAHU and AHU equipment placement. It features sections E-E and F-F at 1:50 and 1:100 scales, plus a full legend for duct types and symbols. You’ll find specific flow rates like 5000 L/s for AHU-1 and 2100 L/s for FAHU-1 nooted throughout. This could be useful in mosque design or large-scale commercial MEP planning.
