Mission and programs · 2024

Mission

To disseminate multi-disciplinary information on all aspects of tall buildings and sustainable urban environments, to maximize the international interaction of professionals involved in creating the built environment, and to make the most recent knowledge available.

Activities or mission (Part I)

To disseminate multi-disciplinary information on all aspects of tall buildings.

  • CTBUH events offer a wide variety of benefits to attendees, speakers, and sponsors. As the recognized international authority on tall buildings, CTBUH conferences are best known by industry leaders for both quality of knowledge-sharing and networking opportunities. By holding conferences and events throughout the world, CTBUH maximizes the international interaction of professionals involved in creating the built environment and makes the most recent knowledge available to these professionals.

    Expenses $2,304,358 · Revenue $1,399,312

  • CTBUH's membership is made up of the world's leading owners, developers, planners, engineers, designers, suppliers, and builders of the vertical urban realm. Through meaningful, multidisciplinary engagement, CTBUH offers its members the opportunity to share best practice information, promote their expertise globally and in their local region, and shape the future of cities. CTBUH Assemblies comprise dynamic, member-driven committees that can contribute their expertise to CTBUH in many ways: educational programming, research publications, journal articles and peer review participation.

    Expenses $889,770

  • CTBUH performs objective research and thought leadership at all scales and distributes findings in the form of technical guidelines, white papers, data studies, and reports that highlight critical issues facing tall buildings and future cities.

    Expenses $759,071 · Revenue $183,595

  • CTBUH developed the international standards for measuring and defining tall buildings, as outlined on its website, and is recognized as the arbiter for bestowing designations such as the "World's Tallest Building." These standards also inform the basis of the CTBUH Tall Building Database, the world's premier online resource for accurate, reliable information on tall building data. The CTBUH website provides the public with detailed data, images, and technical information on more than 40,000 tall buildings, and their cities, the world over.

    Expenses $624,083

  • Through the publication of books, proceedings, technical guides, research reports, and a monthly newsletter, CTBUH disseminates multidisciplinary information on all aspects of tall buildings and sustainable urban environments.

    Expenses $573,580 · Revenue $97,782

  • CTBUH offers annual competitions for professionals and students to engage in design and research projects. The evaluation of competition proposals and designs are undertaken by an expert peer review committee, which reflects a multi-disciplinary group of tall building/urban experts from around the world with experience in varying fields. The Masters of Tall Buildings and Vertical Urbanism (M.TBVU) program is a collaboration between CTBUH and the Illinois Institute of Technology (IIT), and is the world's first multidisciplinary advanced degree focused specifically on the high-rise and the role of urban density in future cities.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
