This overview is the most accurate compilation of its kind and uses in-depth research results and reliable building information. It is based on data standards as outlined by the Emporis Standards Committee (ESC). This listing is verified and updated continuously and includes high-rise buildings which have been topped out, including those still under construction or on hold and whose occupiable height is devoted at least 90% to office uses. The ranking is based entirely on the buildings' structural height. TV towers, masts, and other building types are not included.
