Guideline 36 Savings Calculator

This repository contains models, analysis scripts, and preliminary calculator for estimating savings potential of ASHRAE Guideline 36 control sequences.

Savings Calculator

A preliminary calculator to estimate savings is implemented in G36_savings_calculator.xlsx based on simulation results from the models within this repository. See the README sheet within the spreadsheet for more information.

Models

Models are contained within the Modelica package BestInClass. Processing scripts are in process. To simulate the models, please follow the steps below:

  1. Install Git LFS first if you have not installed it on your system.

  2. Update your modelica-buildings branch to issue1129_energyPlus_zone to the latest commits.

  3. If the branch issue1129_energyPlus_zone is behind master, please merge master to issue1129_energyPlus_zone branch. This will be the base branch for the use with the models.

  4. Clone this repo and check out to the main branch.

  5. See BestInClass.DetailedZoning for models that can be run.

  6. You can also run models in batches using the script process/simulate.py (BuildingsPy installation is requried) and be careful with the output folders.

  7. If your Dymola version is under 2021, set Hidden.AvoidDoubleComputation = true in the Dymola command window before simulating the models.
