ASHRAE Design Guide for Tall, Supertall, and Megatall Building Systems, 2nd Ed. PDF

Cosponsored by CTBUH

Tall (taller than 300 ft [91m]), supertall (taller than 984 ft [300 m]), and megatall (taller than 1968 ft [600 m]) buildings present unique and formidable challenges to architects and engineers because of their size, location in major urban areas, and the multiple, complex occupancies they often contain. ASHRAE Design Guide for Tall, Supertall, and Megatall Building Systems, second edition is a unique reference for owners; architects; and mechanical, structural, and electrical engineers as well as other specialized consultants involved in designing systems for these buildings.

Expanded since the first edition published in 2015, this new design guide covers broadened scope and updated content that reflects current standards and industry practices, including major sections on architectural design, indoor air quality (IAQ) and thermal comfort, vertical transportation, life safety, residential occupancy needs, and intelligent buildings and controls

Also included are appendices with examples documenting climatic calculation for four representative climates, energy analysis, and HVAC design criteria and systems descriptions for a multiple-tenant office building. There are also nine new case studies illustrating real-world tall buildings across the globe.

ASHRAE Design Guide for Tall, Supertall, and Megatall Building Systems, second edition is accompanied by helpful spreadsheets, which can be downloaded for free online.
