Facility and property context
San Marcos is in Hays County. Common property categories relevant to HVAC planning include:
- Education and university-adjacent buildings
- Multifamily properties
- Retail and hospitality
- Healthcare and public facilities
- Industrial and distribution buildings
Academic calendars, student-oriented occupancy, I-35 access, river-area humidity, large retail roofs, multifamily unit access, and continuous operations require scope-specific planning.
Local climate and system considerations
High occupancy, seasonal population changes, long cooling periods, river-area humidity, large retail and warehouse roofs, and fast construction cycles can stress ventilation, controls, drainage, airflow, and maintenance programs. Winter readiness remains necessary despite dominant cooling loads.
