1. ABOUT THE DATASET -------------------- Title: Data for - A Novel Analytical Approach for Evaluating Thermally Active Underground Retaining Walls Creator(s): Aakash Gupta[1], Fleur Loveridge[1], Ida Shafagh[1], Simon Rees[1] Organisation(s): 1. University of Leeds Rights-holder(s): Aakash Gupta, Fleur Loveridge, Ida Shafagh, Simon Rees, Copyright 2025 University of Leeds Publication Year: 2025 Description: This dataset contains all numerical and analytical results developed for the paper "A Novel Analytical Approach for Evaluating Thermally Active Underground Retaining Walls". The numerical results correspond to simplified two dimensional models for energy walls that were created in the COMSOL Multiphysics 5.5. All numerical models have a time step of 1 hour and a simulation period of 1 year. Parallelly, temperature changes were also calculated through the analytical method, which here is the FIS method or Flux and IPS Splitting method, which used IPS or Infinite Plane Source as the base model to compare energy wall to a planer source. The data sheets presented in this data set contains all these information along with the variables used in the calculations. Through this, any information presented in the article can either be calculated, cross-checked or derived.

PROJECT AND FUNDING INFORMATION ---------------------------------- Title: Integrated Infrastructure for Sustainable Thermal Energy Provision (IN-STEP) Dates: Jun 18 - Dec 22 Funding organisation: EPSRC Grant no.: EP/S001417/1 4. CONTENTS ----------- File listing 1. "01_All_GG_JP01.xlsx": This is an excel data sheet that contains information related to the fully buried energy walls - GG (Ground-Ground) in the journal article titled "A Novel Analytical Approach for Evaluating Thermally Active Underground Retaining Walls". This sheet contains all numerical results and analytical results. This contains all parametric cases connected to GG energy walls. 2. "02_All_GE_JP01.xlsx": This is an excel data sheet that contains information related to the exposed energy walls - GE (Ground-Excavation) in the journal article titled "A Novel Analytical Approach for Evaluating Thermally Active Underground Retaining Walls". This sheet contains all numerical results and analytical results for all parametric cases connected to GE energy walls. 3. "03_Para_Results.xlsx": This is an excel data sheet that contains information related to the parametric analysis performed in the journal article titled "A Novel Analytical Approach for Evaluating Thermally Active Underground Retaining Walls". This sheet only contains the final results. The main data can be found in sheet "01_All_GG_JP01" for fully buried energy walls, and "02_All_GE_JP01" for exposed energy walls. 5. METHODS ---------- Data was generated by two procedures: 1. Numerical Analysis: Numerical analysis was performed in COMSOL Multiphysics 5.5. All data related to simulation can be found in the publication connected to the dataset. Whereas, all parameters used in each model can be extracted from the data sheets provided. 2. Analytical Analysis: The analytical analysis uses Infinite Plane Source (IPS) as base model to represent the planar geometry of the energy wall. The calculations are performed through the Flux and IPS Splitting Method or the FIS method, to calculate the temperature changes at the ground wall interfaces. The calculated temperatures can be seen for each case in the data sheets, whereas all formulae and method is discussed in the publication related to the dataset.
