The basement routine is used to calculate the face
(surface) temperatures on the outside of the basement wall or
the floor slab. This is the plane between the outside
insulation and the basement wall. The insulation thermal
resistance can range from zero (no insulation) to any
reasonable value. The units are K/(W/m\(^{2}\)). The program will
simulate two conditions: full insulation from grade to the
footing or half insulation that extends halfway down from
grade to footing. The temperature on this plane is used with
the OtherSideCoefficients object in EnergyPlus to supply the
outside face temperature of the walls or slab.
The output from the program is a csv file, named
MonthlyResults.csv, as shown below.
Output from Basement program
[fig:output-from-basement-program]
Column B gives the basement zone temperature. This can vary
month by month as will be explained later. Column C is the
monthly average wall outside face temperature, as shown in the
diagram above. Column D is the corresponding average monthly
average inside wall face temperature. Columns E and F contain
the same information for the basement floor slab. Columns G-J
contain the same information for the upper half and the lower
half of the basement walls.
Columns K through N contain the monthly average heat flux
for the floor, the walls, the upper half of the walls and the
lower half of the walls. The flux is reported in units of
W/m\(^{2}\).
The program also produces an output file named
EPObjects.TXT. This file contains the necessary idf objects to
make it easy to include the wall outside surface temperatures
in an EnergyPlus input file. Idf objects for all of the
temperatures in the output file shown above are included.
These objects are explained in detail in the section Using the
Interface Surface Temperature Results in EnergyPlus.
