Technical Guides
The output of CTBUH Working Groups, and other Council-led committees, is published in the form of Technical Guides as shown below.
Outrigger Design for High-Rise Buildings (2012)

An output of the CTBUH Outrigger Working Group, this guide sets out a comprehensive overview of the use of outriggers in skyscrapers. This guide offers detailed recommendations for analysis of outriggers within the lateral load resisting systems of tall buildings, for recognizing and addressing effects on building behavior and for practical design solutions.
Natural Ventilation in High-Rise Office Buildings (2012)

An output of the CTBUH Sustainability Working Group, this guide sets out recommendations for every phase of planning, construction, and operation of natural ventilation systems in these buildings, including local climatic factors that need to be taken into account, how to plan for seasonal variations in weather, and the risks in adopting different implementation strategies.

Authored by the co-chairs of the CTBUH Seismic Design Working Group, the objective of this guide is to set out best-practice principles for the seismic design of high rise buildings for any level of seismic hazard.

CTBUH Comments on NIST WTC 7 Collapse Report  

World Trade Center Building 7 (2008)
CTBUH Comments on the 2008 NIST report

In August 2008, NIST issued their report on the Structural Fire Response and Collapse Sequence of WTC Building 7, for Public Comment. This brief report contains feedback from the CTBUH on the NIST report.

Emergency Evacuation Elevator Systems Guideline  

Emergency Evacuation: Elevator Systems Guideline (2004)
Edward Cardinale, Charles Mattes, Carl Galioto, et al.

Includes key issues that design teams should consider in the development of emergency evacuation for tall structures, using three generic types of evacuation, three design approaches to emergency elevator systems, and necessary evacuation systems training.

Building Safety Enhancement Guidebook / Building Safety Guidebook Set   Building Safety Guidebooks (2002)

The purpose of the guidebooks, written in a post-9/11 society, is to educate occupants of tall buildings and give building owners and designers a tool to evaluate the need for additional safety and security features.
Task Force on Tall Buildings: The Future   Task Force on Tall Buildings: The Future (2001)

This document is a transcript from the CTBUH Task Force on Tall Buildings meeting held on October 15, 2001, five weeks after the attacks on the World Trade Center Towers. The meeting set a direction and an agenda that the industry could then follow in response to September 11th..
