Project Overview

An administrative building at Hyde Park, Cairo, with a 48 m² main hall (20 occupants) and 24 m² of offices. We started with load calculations in Carrier HAP 5.10 (about 28.6 MBH peak cooling for the main hall), then designed three ducted fan coil units tied into the chilled-water loop with BTU meters, together with plumbing, AC condensate drainage, a sprinkler network and extinguishers. Drawings were issued in October 2025 and revised through Rev03.

The Challenge

  • Small spaces with relatively high loads (a 20-person hall) and limited ceiling void
  • Tying into an existing chilled-water loop with BTU meters and balancing valves
  • Coordinating 1% fall for condensate drains above the ceiling

Our Scope

  • Load calculations for the main hall (28.6 MBH) and offices (12.0 MBH)
  • Three chilled-water fan coils: 1.5, 0.825 and 1.0 TR (700, 300 and 510 CFM)
  • Chilled water at 44.6 to 53.6 °F with BTU meters and balancing valves
  • Cold and hot water, drainage and AC condensate drainage
  • Pendent sprinklers (68 and 79 °C), supervised valves, flow switch, 25 mm × 30 m hose reel and extinguishers
  • Coordination drawings, installation details and ceiling layouts

Solution & Results

Technical Highlights

  • HAP calculation reports for the hall and offices
  • Chilled-water network with a BTU meter per unit
  • A full drawing set: HVAC, piping, drainage, fire protection and coordination

Deliverables

  • Load calculation reports (main hall and offices)
  • Fan coil schedule, ducting and piping drawings
  • Plumbing, drainage and AC condensate drawings
  • Fire protection layout and installation details
  • Composite and ceiling layout drawings
  • Fan coil selection (technical data sheet)
