New or Renew?



23–27 September

Today, the construction industry is facing a challenging dilemma: Should we build new buildings, or should we renew the existing ones? In parallel, governments and city-makers debate over the need to grow existing, or to build new, more sustainable cities. The dilemma poses further challenges: How do we make these decisions, and who should be involved?

New or Renew refers to the choice between new buildings and cities, or the adaptation of the existing for the sake of environmental, economic and social sustainability. This is not about the conflict between old and new, or heritage versus future. Instead, the Council on Tall Buildings and Urban Habitat seeks to identify strategies for transformation and growth that bring new blood to urban life. There is a new generation of tall buildings and shapes of density to be discovered, which provides new opportunities for flexibility and energy savings, as well as a substantial reduction of impact on the environment.

Answer the call—be part of the discussion and join us from 23–27 September 2024, in London and Paris, for New or Renew: Addressing the Density Dilemma.

Location & Venues

The 2024 CTBUH International Conference will take place in London and Paris, two historic capital cities at the forefront of this vital question. The past decades have seen a radical transformation of London’s skyline, in both new-built and traditional business districts, as well as in new centers in the outer boroughs. Policy questions around affordability, carbon footprint and preservation are forcing us to rethink the way planning and construction decisions are made.

Paris is grappling with many of the same issues, though its policy responses have differed—a recent ban on new tall buildings within the city limits raises the stakes of the density dilemma. The upcoming 2024 Olympics are set to transform the landscape, while La Défense, the iconic business district built during the 1970s, is also looking for ways to have a second life.

The issues and transformations being undertaken by these cities are representative of a global phenomenon, in which cities are reevaluating the potential of existing structures, seeking to become greener, or even considering to be reset in new locations with different parameters. Given this confluence, the CTBUH 2024 International Conference will be a vital event for all concerned with the future of cities.
