Energy
Efficient:
A benefit that is high on the list is energy consumption,
According to a study by the British Cement Association
the thermal mass of a building can absorb heat throughout
the day, reducing internal summertime temperatures by
37 to 39 degrees and in reverse supplementing winter heating
needs for several hours each night. The United States
Department of Energy software simulation programs, DOE-2
and Energy Plus, now give concrete a decided advantage
over other types of building materials
simple R
or U values don't tell the whole story as more is discovered
about the benefits of thermal mass.
Metal,
wood and even clad masonry buildings require fasteners
to connect the outside panels or façade to the
building supports. These fasteners provide a "thermal
short circuit" (known as thermal bridging), significantly
reducing the overall performance and thus the full R-value
of the wall. Additionally whenever batt insulation is
compressed it loses R-value. Most metal systems squeeze
the batts between the outside sheeting and the support
girths
.an R-19 batt is taken down to R-11 in such
a case.
Modular
precast components minimize air infiltration due to the
few joints, they offer an R-24 insulating value, and the
concrete's thermal mass keeps temperatures even.
The
best way to determine required values for a given area
is with software called COM-check-EZ. Under the category
"Other" you can enter precast wall thermal values
-(available from Thermo-Mass) to compare with other systems.
