Abstract
False ceilings are non-structural elements present in buildings of all types. They act as passive protection elements and give the rooms in which they are located significant technical capacities. For healthcare buildings, false ceiling systems require a higher level of qualification than in other buildings, with strict requirements for acoustic insulation, fireproof stability, resilience, and noise absorption. In addition, they require exhaustive analysis, design, and sizing processes to ensure a high degree of reliability. This fact complicates their optimal selection. In this study, a multidimensional comparative analysis was made of 14 false ceiling systems that predominate in Spain's healthcare infrastructure. An analytic hierarchy process (AHP) was applied according to five pre-defined variables (LCA, Unit price, Working time, Thermal conductivity, and Maintenance accessibility) based on the technical, environmental, economic, and temporal dimensions. Life cycle assessment was used to define and quantify the environmental variables’ characteristic impact parameters. The optimal solution was found to be the removable mineral fibre system, with a value of 0.82 AHP pt/m2. This system has good technical properties and facilitates maintenance and cleaning tasks. In contrast, the continuous cement board false ceiling system was found to be the least favourable, with a score of 0.18 AHP pt/m2. The knowledge gained from this study will favour optimal decision-making in sizing healthcare infrastructure by providing a detailed view of that infrastructure to those responsible for its engineering, thereby enhancing the socioeconomic and environmental benefits.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
