⚠ High Latent Load (SHR < 0.75): Consider a dedicated dehumidification system, hot gas reheat, or desiccant wheel to handle excess moisture.

✔ Normal SHR: Standard DX or chilled water cooling coil can handle this load profile.

Equipment Note: Equipment SHR is typically 0.70–0.80. If your space SHR is lower than equipment SHR, the space will be over-cooled (too cold) before meeting humidity targets — consider supplemental dehumidification.

📚 Typical SHR by Space Type

Space Type	Typical SHR	Latent Load Source	Level
Office / Commercial	0.85–0.95	People, ventilation OA	Low Latent
Retail	0.80–0.90	People, OA, infiltration	Low Latent
Restaurant / Kitchen	0.65–0.75	Cooking, high OA, steam	High Latent
Gym / Fitness	0.65–0.75	Heavy occupancy sweat load	High Latent
Natatorium / Pool	0.30–0.55	Evaporation from water surface	High Latent
Hospital Patient Room	0.70–0.80	People, OA requirements	Med Latent
Warehouse	0.90–0.98	Minimal occupancy	Low Latent
Humid Climate (summer)	0.70–0.80	OA humidity, infiltration	High Latent
