How to integrate curtain wall with HVAC efficiency?

Efficient HVAC integration in curtain-wall façades—especially in Riyadh or Doha offices—demands careful coordination between façade design and ceiling layouts. First, locate perimeter air-conditioning diffusers flush with aluminum ceiling grids adjacent to the curtain wall; this creates a thermal buffer that keeps cold air within. Second, use undercut thresholds at entrances to reduce infiltration. Third, design pressure-equalized curtain-wall cavities to vent heat buildup, cutting load on HVAC coils. Fourth, select variable-air-volume (VAV) boxes in ceiling plenums to modulate airflow based on outdoor conditions. Fifth, employ energy-recovery ventilators to pre-cool incoming air via the curtain-wall cavity exhaust. By harmonizing curtain-wall pressure zones and aluminum ceiling plenums, projects in the UAE and Kuwait achieve up to 25% energy savings.
