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

Three convention centre MEP failures

1. 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.
2. 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.
3. 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.
