Examples of net and gross floor area in a high-rise.

When: Sunday, 29 October 2017
Venue: Rider Levett Bucknall’s North Sydney Office, 141 Walker Street

Kindly Hosted by:

The tall building, no matter where it is constructed, is increasingly a multinational enterprise comprising expertise from around the world. However, techniques for measuring floor space within a tall building vary considerably between regions. The lack of internationally accepted standards means that the floor-area demands of a client may not always line up with the definition of floor areas for a designer or governing body based in a different country.

Just as the internationally recognized method of measuring height was created and refined by CTBUH, we now seek to set the international standard for measuring Net and Gross floor area in tall buildings. The Council has received a research sponsorship grant from ArcelorMittal, to undertake a one-year project to investigate the worldwide methods currently used for calculation and arrive at a consensus.

Through a half-day workshop on Sunday, Oct. 29 in Sydney, Australia, in conjunction with the 2017 CTBUH Conference beginning the following day, CTBUH will convene the leading industry authorities on floor-area calculation from around the world, with the following objectives:

  • Nominate individuals to get involved with the Research Project
  • Present succinct summaries of the dominant calculation methods and CTBUH research undertaken so far
  • Develop an initial consensus about best calculation approaches
  • Begin discussions about which designations should be codified into CTBUH criteria, including “The World’s Largest Building,” “The World’s Most Efficient Building,” and others that not only recognize the floor area requirements of the building’s developers, but the ability of the designers to positively influence the net-to-gross ratio

Dr. Dario Trabucco, CTBUH Research Manager, will lead the workshop.

The workshop will be led by the research project’s principal investigator, Dr. Dario Trabucco, CTBUH Research Manager and Tenured Researcher in Building Technology, IUAV Venice.

Representatives from the following disciplines are expected to attend:

  • Property leasing and management
  • Property development
  • Architecture
  • Structural engineering
  • Quantity surveyors
  • MEP engineering
  • Interior designers
  • Others
