Submission format: submit a python script file(s) (.py file) and a word file on Moodle
Text-based Interface of Energy Modeling
Building energy modeling is an important tool to help engineers predict and analyze building
energy consumption under various design and operation conditions. You can get the energy
demand of a building even before you actually build it, and you can get to know the effects of
some key thermal parameters on the final energy performance of your design.
While most building energy modeling software has a nice graphical user interface (GUI), it is
beyond your ability at this stage of the module. Therefore, this project will just ask you to
develop a simple text-based user interface to perform energy modeling based on a popular
engine named EnergyPlus.
Requirements
- In this coursework, you are given a model file (1ZoneIdealSys.idf) and a given weather file
shanghai_2017.epw. You need create a software with text-based interface by using Python
argparse feature to realize the following features:
◼ When user gives a starting U-value, an ending U-value (inclusive), a step interval
(e.g., 0.2, 3.0, 0.2 respectively), your software should be able to output a single bar
chart file (a .PNG image file) to visualize annual total heating energy consumption
and annual total cooling energy consumption at different U-values (i.e., 0.2, 0.4, 0.6,
0.8, …, 3.0). In this bar chart, the x-axis is U-value, and the y-axis is annual total
heating/cooling代写Architectural Engineering Design energy consumption. You should use different colors to represent
heating and cooling energy consumption bars. - Write a short paragraph (less than 300 words, in MS Word), comment on the effects of wall
U-value on the heating and cooling energy consumption. You should use the bar chart
generated by your software above. Explain the effects based on heat transfer principles (e.g.,
your PCM contents).
Marking Rubrics
Requirements Marks
1 Interface: correct implementation of the text based interface using Python argparse feature.
The text-based interface should have meaningful
argument names and argument explanations.
10
2 Runnable: your software must be runnable
without error. You software must be able to
10
handle the wrong arguments given by users, e.g.,
starting U-value is smaller than the ending U value.
3 Correctness: your code has correct
implementation of the requirements, and can
generate the output image with correct results.
40
Chart presentation: The output bar chart should
have correct axis labels, legends, and correct
color coding
10
Styles: Right programming styles (discussed in
our session 2)
10
Analysis: Clear and correct analysis on the effects
of U value on heating and cooling energy
consumption, with strong reference to the charts
that have been plotted; correct English usage
without grammar errors; correct explanation
based on heat transfer principles.
