Designing an ERV is not just about adding a heat exchanger to the ductwork. This guide explains ERV sizing, sensible and latent recovery, key formulas, design mistakes, and real engineering application in DOAS and commercial ventilation systems.

Designing HVAC systems for net-zero energy buildings requires high-efficiency technologies, smart controls, and load reduction strategies. By integrating heat pumps, energy recovery ventilation, radiant systems, and renewable energy, engineers can significantly reduce building energy consumption while maintaining indoor comfort and sustainability. 🌱

HVAC load calculation determines the heating or cooling capacity required to maintain comfortable indoor conditions. Engineers evaluate factors such as building envelope heat transfer, solar gain, occupancy, lighting, equipment, and ventilation. Accurate load calculations ensure proper HVAC system sizing, improving energy efficiency, performance, and indoor comfort while preventing oversized or undersized systems.
