Hilton Worldwide says that it is the fastest growing hospitality company as it leads the way in global hotel construction. 

President and Chief Executive Christopher Nassetta said that the hotel chain has the largest number of rooms under construction in the industry, with more than 174,000 rooms undergoing work. 

Hilton opened a total of 399 hotels last year comprising of 59,100 rooms. This equates to net room growth for 2017 standing at 51,600 rooms. 


Neary 20% of these new properties were across five of the group's newest brands -  Tapestry Collection by Hilton, Canopy by Hilton, Curio – A Collection by Hilton, Home 2 Suites by Hilton and Tru by Hilton.

The hotel group also reached several milestones this year including opening its 100th property in Greater China and passing 100,000 rooms trading the EMEA region.

The figures were revealed as Hilton announced its full-year results for 2017.

Hilton also reported strong fourth-quarter profits that beat Wall Street estimates, as demands for rooms picked up in China thanks to a surge in travelling

Revenue per available room (RevPAR) from the region, a key performance indicator for the hotel industry, rose 7.6% as the company benefited from its growing footprint in China. 

“We feel great about our set up for 2018 and our ability to continue delivering record-setting results,” said Christopher Nasetta, president and chief executive of Hilton.

University of Dresden constructs carbon concrete building

The Technical University of Dresden, collaborating with German architecture firm Henn, is constructing the world’s first carbon fibre and concrete building

The Technical University of Dresden, in partnership with German architecture firm Henn, is constructing the first building to be made out of concrete and carbon fibre, rather than traditional steel. 

The combination of materials, known as, “carbon concrete” has the same structural strength as its steel-reinforced alternative but less concrete is used, according to researchers at the university. 

The building, called “The Cube” is currently under construction at the University of Dresden’s campus in Germany, and is believed to be the first carbon concrete building in the world. Strengthening the concrete, the carbon fibre yarns are used to create a mesh into which the concrete is then poured.

Unlike steel, the mesh is rust-proof meaning that the lifespan of carbon concrete is longer than that of the more typical steel-reinforced concrete. This also allows the layers to be much thinner than steel. 

The design and shape of The Cube 

According to the companies, the flexibility of carbon fibre allows the walls to fold up and become a roof. In a statement talking about the building’s design elements, Hen said: “The design of The Cube reinterprets the fluid, textile nature of carbon fibres by seamlessly merging the ceiling and walls in a single form, suggesting a future architecture in which environmentally conscious design is paired with formal freedom and a radical rethinking of essential architectural elements.

"The wall and ceiling are no longer separate components but functionally merge into one another as an organic continuum.” Displayed as a showpiece for TU Dresden’s major project, backed by the German Federal Ministry of Education and Research, The Cube aims to explore the potential uses of carbon concrete in construction. 

"Carbon concrete could contribute to more flexible and resource-saving construction processes, and switching to carbon concrete could reduce the CO2 emissions from construction by up to 50%," Henn said in a statement. 

Bio-based carbon fibre under development to reduce carbon footprint

While carbon fibre may be lighter and stronger than steel, it has a much higher carbon footprint. Describing the material’s impact on the environment, Dr Erik Frank, Senior Carbon Scientist at the German Institute of Textile and Fibre Research Denkendorf (DITF), said it is “usually very bad.” To reduce the carbon footprint, Frank is finding ways to make carbon fibre out of lignin, a common plant-based substance found in the paper manufacturing industry.
