Tall-buildings experts, who are past chairs of the Council on Tall Buildings and Urban Habitat, are calling for more CTBUH research and development, better tools and greater building team collaboration to make high-rises more sustainable.

The Council on Tall Buildings and Urban Habitat, in its 2018 CTBUH Tall Building Year in Review, found that 18 supertall buildings 300 meters or taller completed construction last year—a record number that beats 2017, but only by three.

In the decade since Antony Wood became executive director of the 47-year-old Council on Tall Buildings and Urban Habitat, membership has increased by 539%, the annual budget has increased to $5 million from about $225,000, and the staff has increased to the equivalent of 31 full-time positions from only two, according to the Chicago-based CTBUH.
