Tasks and weights

1.  You should use IES-VE to develop a model and evaluate the cooling load in the summer design day.  [20%]

2.  You should use Matlab to calculate and plot the cooling load with time interval of 10 minutes in any one of the rooms in the summer design day (21st  July). Assume the initial building temperature is 25 oC (Hard mode: You are encouraged to run a 10-day pre-conditioning for the previous day (20th July) in order to get the initial condition for the day of 21st July. You can assume the initial building temperature is 25 oC on 20th July. NOTE: students may get higher marks on this part by finishing the hard mode).

To obtain the cooling load, you should:

Derive a 5 node finite difference models for all walls and roof. Use appropriate time step ∆t so the Fourier Number Fo ≤ 0.5 .

Solve and plot convective transfer coefficient h for all exterior surfaces of walls and roofs, using either Simple-combined, TARP or McAdams algorithms.

Solve and plot h for all interior surfaces of walls and roofs, using either Walton model or Alamdari – Hammond model.

Calculate the solar radiation with either ASHRAE Clear Sky Model or Zhang-Huang Model. (Easy mode : student can choose to adopt the direct and diffuse solar radiation from weather data. NOTE: students may not get high marks on this part by choosing the easy mode)

Calculate the convective heat exchange between air and interior surfaces, assuming the temperature of internal walls is maintained at 25 oC and the interior long-wave radiation among internal surfaces is neglected. (Hard mode : Students can choose to calculate long-wave radiation among all interior surfaces and the temperatures of all interior surfaces. NOTE: students may get higher marks at this part by finishing the hard mode)

Calculate and plot cooling load using Heat Balance Method.  [50%]

3.  Compare the IES-VE results and Matlab results on the summer design day. Discuss what causes these differences.  [20%]

*Presentation and clarity of the report.

Interim progress check

There will be three interim progress checks on 16th October, 6th November and 27th November 2024, respectively. Students will have to bring their ongoing work to the class and present the progress to the tutor individually.

Coursework Submission Deadline

You should submit your report on Moodle AND a compressed model folder (including IES- VE files and Matlab files) to me via emails no later than 4.00pm on Thursday 12th December 2024.
