BRICK STRUCTURE.
The brick enclosure system consists of 4" face brick, 4" common
brick and 4" glazed tile laterally supported by masonry encased
columns.
ADVANTAGES. Adjustable to
deviations in field dimensions and opening locations, modular
manufactured unit easily handled
by the bricklayer, can be scheduled with other trades to allow a
coordinated construction sequence, relatively maintenance
free exterior and easily cleaned interior.
DISADVANTAGES. Increased job
site erection time compared with panel wall construction. All
criteria considered the utility of the wall depends on the brick
layers expertise. Improperly executed joints affect the walls
structural capability and watertightness.
CONCLUSIONS. This enclosure
system provides a long term maintenance free installation but at
increased life cycle cost. Over
estimated energy consumption based on published steady state "U"
values rather than capacity insulation may contribute to part
of the increased cost. Energy consumption could be reduced
significantly by cavity wall construction and rigid insulation. The
structure design would require reinvestigation as cavity wall
construction requires closer lateral support spacing which in some cases may not be practical.
But in this example the fuel savings based on steady state
computations could approach $17,000.00 over the building life period. |
