Convention Centre MEP — Bharat Mandapam Class + ICCA + UFI + ASHRAE Handbook Ch 4
An 80,000 m² Tier-1 Indian convention centre (Bharat-Mandapam-class) demands ₹440 Cr MEP capex with 17.3 lakh CMH total smoke exhaust covering 12,000 m² column-free exhibit hall + 5000-seat plenary + 24 breakouts + 3500 m² banquet. ASHRAE Handbook Ch 4 + ASHRAE 62.1 + ICCA + UFI + ITPO govern. Three failures: exhibit hall HVAC zoned by structural grid instead of high-density VAV (every 100-200 m²) with plug-in floor diffusers, breakout acoustic + IAQ commissioning grouped 6-8 on shared AHU killing concurrent-event flexibility, parking smoke without conv-centre evacuation interlock letting smoke ingress through pedestrian links.
Convention centre MEP — the design event
Indian Tier-1 convention centres (Bharat Mandapam Pragati Maidan, Yashobhoomi Dwarka, BIEC Bengaluru, HITEX Hyderabad, Chennai Trade Centre, Lulu IICC Delhi planned) host 5000-15,000 delegate G20-class events + 25,000+ visitor expo events with concurrent banquet + plenary + breakout. ASHRAE Handbook 2023 Ch 4 + ASHRAE 62.1 Table 6-1 + NBC 2016 Pt 4 Annex F + IFEA + ICCA + ICCA Convention Centre Design Guidelines together govern. The MEP signature challenge is exhibit-hall heat-load swing (50 W/m² empty vs 280 W/m² at trade-show peak) + plenary acoustic privacy (NC 25-30) + breakout room flexibility.
Pragati-Maidan-class convention centre MEP — 80,000 m² with 3 hall types
| Zone | Capacity | Cooling load (W/m²) | OA (L/s/pax) | Smoke design (MW) | Smoke exhaust (CMH) |
|---|---|---|---|---|---|
| Exhibit hall A (column-free 12,000 m²) | 12,000 visitors | 280 (trade-show peak) | 9 | 5 MW (timber booth) | 480,000 |
| Exhibit hall B (5000 m²) | 5,000 | 280 | 9 | 5 | 200,000 |
| Plenary auditorium (5000 seat) | 5,000 | 120 + radiant | 9 | 3 | 180,000 |
| Breakout rooms (24x ~500 m²) | 7,200 aggregate | 110 | 9 | 3 (per room) | 42,000 each |
| Banquet hall (3500 m²) | 3500 | 180 | 9 | 3 | 125,000 |
| Pre-function + lobby (8000 m²) | transient surge | 85 | 9 | 5 | 280,000 |
| Press centre | 400 | 115 | 9 | — | — |
| Kitchen / catering (back-of-house) | — | — | 15+hood | — | NFPA 96 |
| Basement parking (5000 cars) | — | — | — | 5 (vehicle fire) | 420,000 |

Three convention centre MEP failures
- Exhibit hall HVAC zoned by structural grid not by exhibition layout — events install partitions that dont align with HVAC zones. Specify high-density VAV grid (every 100-200 m²) + plug-in floor diffusers so exhibition designers can configure climate per booth.
- Breakout room acoustic + IAQ commissioning skipped — small rooms need NC 30 ceiling + ASHRAE 62.1 9 L/s/pax + dedicated thermostat. Most Indian convention centres group 6-8 breakouts on single AHU = uniform thermal complaints + inability to programme concurrent events.
- Parking smoke fans without conv-centre evacuation interlock — basement parking 5 MW vehicle fire + 25,000 evacuating delegates above. Smoke fans + evacuation logic must synchronise to prevent pedestrian-link smoke ingress.
