Case Study: Hilton, San Fransisco

Known for its accommodations and hospitality, the Hilton San Francisco in Union Square also takes top marks as a venue for business gatherings. The 46-story hotel with 1,908 guest rooms was voted Best Hotel for Meetings and Best Hotel for Business Service in a 2009 survey by Executive Business magazine.

Keeping the hotel’s large meeting areas comfortable with the right blend of ventilation and conditioned air is no small matter for hotel engineering staff. Yet a recent upgrade project to improve airflow and circulation to four ballroom foyers on the second floor not only met project goals, it established a whole new paradigm for easy retrofit, energy savings and system reliability through redundancy.
