| dc.description.abstract | Regardless of the construction processes or employed materials, the NBR 15575
defines objectives, requirements, and methods for assessing the behavior in use
performance of accommodations. Therefore, the influence of the coating layers on the
performance of construction systems is an essential parameter to assess the use of
materials and elements of the systems, in order, to make the project feasible, not only
economically, but also technically. Through computer simulations based on a defined
reference model for the study, the present work study the influence of different layers
of floor, roof and, internal and external, vertical sealing systems, on the thermal,
acoustic, and lighting performance. Finally, analyzing the results, for the reference
model used, identified the materials and elements with the greatest influence on:
lighting performance - the internal finishes of the environment and the type of glass
used in the external frame; thermal performance - all elements of tension, roofing
system and facades, especially an absence of external cladding and the roof system
typology; acoustic performance of the façade - function especially of the external
frame; acoustic performance of the floor system - mainly influenced by the thickness
of the structural element and the use of ceiling and acoustic blanket; acoustic
performance of internal vertical seals - typology of the structured element of the seal
and thickness of the lining. We conclude that coatings have a great influence on the
thermal, acoustic and natural lighting performance of buildings and should be
considered in the design stage, with computer simulations as an important tool. | eng |
