The American Society of Heating, Refrigerating and Air-conditioning Engineers has published a book that provides tips on HVAC construction buildings considereds “tall” — and beyond.
ASHRAE Design Guide for Tall, Supertall and Megatall Building Systems covers buildings that, for the purpose of the book, are defined as “tall” (300-plus feet high), “supertall” (984-plus feet) and “mega tall” (1,968-plus feet).
