DEVELOPMENT OF LANTERN DESIGN FOR THE CLIMATE CONTROL SYSTEM OF THE BUILDING

Abstract

Modern residential buildings are increasingly equipped with specialized climate 
control systems. Such systems are constantly becoming more complicated and nowadays allow to 
control  and,  if  necessary,  maintain  at  a  given  level  a  whole  series  of  parameters  in  structures  - 
temperature  and  humidity  of  air,  its  degree  of  purity  and  ionization,  temperature  and  quality  of 
water, level of illumination and irradiation,  as well as technical design parameters. Placement of 
such climate control systems for low-rise residential buildings is assumed in the building itself, but 
for  high-rise  buildings  such  systems  are  placed  on  the  roof.  In  this  case,  the  practical  task  of 
protecting climate control systems from the dangerous action of aggressive external factors arises. 
The  paper  proposes  the  development  of  a  special  protective  lantern  capable  of  performing 
such  a  function.  Structurally,  the  lantern  consists  of  a  steel  frame  made  of  bent-welded  square 
profiles and translucent filling. Four architectural and constructive versions of the protective lantern 
are considered - arched, pyramidal-elongated, pyramidal and spherical. To select the most rational 
constructive option, numerical modeling was performed based on the finite element method using 
the domestic software product SCAD. Its results made it possible to choose the necessary cross-
sections of the frame  elements in accordance  with the construction current standards in Ukraine. 
Based on the comparison of mass indicators and the market value of protective lantern materials, it 
was finally determined that the spherical lantern has the lowest indicators and is the most rational. 
However, for real buildings that have rectilinear load-bearing structural elements, this option may 
not be effective and may require reworking of the load-bearing structures. Therefore, for practical 
implementation  an  arched  design  version  of  the  protective  lantern  was  chosen.  This  option  is 
recommended  for  practical  implementation  in  the  reconstruction  project  of  a  multi-story 
commercial-office-hotel complex in the city of Pavlograd.
