Studies of the elements that make up the structure of a building have generally focused on topics related to their physical and structural capacities. Although research has been carried out into environmental impact during the life cycle stages, the environmental profile is far from established. This research aims to reduce the gap in the knowledge of this subject, offering useful information to professionals in the construction industry, which will enable them to consider environmental aspects when choosing the best construction systems. The present study applies the methodology of the life cycle assessment (LCA), to analyze and compare four floor construction systems in two different scenarios (“A” with a functional homogeneous unit of 1 m2 and “B” with 1 m² made up of the percentages of the floor system and the special areas of the building). The analysis is performed using the LCA Manager software, along with the Ecoinvent 3.1 database and with a cradle to handover perspective (A1–A5). Comparison was made using two environmental impact methodologies, Eco-indicator 99 and CML 2001. The results highlight the stages A1–A3 as those that generate the greatest environmental impact. Comparing the environmental profiles of the different floor systems, one-way floor systems I and II had the best environmental scores, 30% less than two-way floor system III and 50% less than slab floor system IV.

“…[Figure 1. ] In a period of scarcity like the one the world will face in the future due to its increased population, augmented wealth, and limited resources, it is clear that the abundance of materials required by a tall building in comparison with an equivalent lowrise structure is becoming more and more a problem (Trabucco et al 2015). This is not just due to the economic and environmental cost that many extra materials imply but also to a social pressure that is starting to appear against unjustifiable wastes.…”

The beginning of the skyscraper era was made possible by some key innovations that occurred in the late 19th century. Generally, steel frames and lifts were considered the key technologies, but a third was mentioned by witnesses of the time and then forgotten: the 'flat-arch' system to protect steel beams from fire. Now, The race for the sky is supported by innovation in the two main fields, which would otherwise represent a bottleneck in increasing the height of tall buildings. Fire safety, and safety in general, is probably the hardest barrier to unlimited height growth.

“…There are many studies and publications analysing in much more details Life-Cycle-Assessment and building typologies that have effect on the environment, e.g. [10]. The analysis of the internal composite column was focused on the reduction of global warming potential by differentiation of steel grades and the application of steel products with different carbon footprint.…”

The trends of the modern construction are recognized for many years; go large span, go light structures, go sustainable, and keep it simple. In the holistic approach to construction a column remains one of the key structural elements.This article presents benefits of the application of high strength steel; namely the potential of using S500 and S550 for encased composite columns. The study shows the increase of the buckling capacity and reduction of weight and consequently reduction of the carbon footprint especially when applying XCarb® steel. The results are presented for a single member as well as for an internal column of a 156m high office building.It is assumed in the analyses that the simplified design method for composite columns defined in EN1994‐1‐1:2004 is applicable to higher steel grades and higher concrete compression classes. Different typologies of the encased steel cross sections are considered: simple H section in rectangular encasement, and cruciform section.
