    Location : Bengaluru.

    Building area : 3, 89,160 ft.

    No. Of floors : GF + 11

    Indoor design conditions : 77 F, 50% RH.

    Air volume calculation type : VAV single duct system.

    Peak total cooling load : 600 TR (diversity factor: 10%).

    Cooling Air Flow Requirement : 2, 09,480CFM

    Occupancies : 6336 people. Operation time : Day time working (5 days in


  • Heat load report:

    To obtain:

    The Effective Sensible Heat Factor (ESHF): 0.729 Apparatus Dew Point temperature (ADP): 50 F Total effective heat load: 600 TR

    Parameters considered:

    Solar gain glass. Solar & trans. gain walls & roof. Trans. gain except walls & roof. Infiltration and outside air. Room internal heat. Effective room sensible heat. Effective room latent heat.


    ASHRAE -55(thermal comfort applications). ASHRAE -62.1 (fresh air requirement). ASHRAE -90.1(energy standards for high rise buildings).

    Basic refrigeration and air conditioning by P N Anantanarayana (table- A10 ADP).

  • Duct layout design:

    Method of duct design: Equal friction method.

    Software used : Mc Quay Duct Sizer.

    Duct system : VAV single duct system.

    Parameters considered for sizing:

    Volume flow rate of air.

    Velocity of air.

    Pressure drop.

  • System inspector & PD report:

    Finding critical path.

    Finding total pressure drop of system by revit PD report.

  • Clash detecting

    & Resolving:

  • Equipment selection:

    Selection of Supply and Exhaust FAN

    Selected fans:

    1. Floor wise toilet exhaust fan : Centrifugal- inline direct-


    2. Terrace exhaust fan : single inlet single width (SISW) fan.

    3. Supply air fan : backward curved centrifugal fan.


    LAU fan brochure, KRUGER catalogues for fans.

    NBC part 8- lighting and ventilation. (No of air changes required for toilet-10 & office-6 ACH).

    Selection of cooling coil is made based on following
