+# Summary
+
+This directory contains the [OpenStudio Parametric Analysis Tool (PAT)](https://github.com/NREL/OpenStudio-PAT) (version 3.1.0) project that was used to calibrate the whole-building model to measured data and produce the `in.idf` for the co-simulation.
+
+## /data
+
+This folder contains supporting data files used for the architectural and mechanical calibrations. These files are also the same files used for the co-simulation.
+
+### schedulefile_*_15min.csv
+
+These files contain the annual 15 minute interval data used by the `Schedule File` measures to add measured data to the simulations. The `elec` file contains the electrical power in Watts for the AC and DC equipment. The `mech` file contains the adjacent thermal zone temperature in Celsius.
+
+### timeseries_objective_function_*.csv
+
+These files contain the measured data for the architectural calibration (zone and plenum temperature in Celsius) and the mechanical calibration (cooling load and fan power in Watts).
+
+## /notebooks
+
+This folder contains Jupyter Notebooks to create supporting data files and plots.
+
+## /pat_project
+
+Self-contained folder for the PAT project. When opening this folder in the PAT application, the following changes will need to be made to successfully run the project.
+
+1. The `Schedule File` measures `File Path` arguments will need to be changed to the corresponding `schedulefile_*_15min.csv` files in the `/data` folder.
+2. The OpenStudio Results reporting measure will need to be added to the project and assigned to all design alternatives.
+3. The `Time Series Objective Function` measures `Path to CSV file for the metered data` will need to be changed to the corresponding `timeseries_objective_function_*.csv` files in the `/data` folder.
+
+### /measures
+
+This folder contains the measures used in the PAT project. See the README files for descriptions.
+
+### /seeds
+
+This folder contains the OpenStudio Models (version 3.1.0) used in the PAT project, described below.
+
+#### FLEXLAB_X3_0uncal.osm
+
+Uncalibrated model for reference.
+
+#### FLEXLAB_X3_1arch.osm
+
+This OpenStudio model was used for the architectural calibration from Oct 30 - Nov 4, 2020 with a preceding warmup period from Oct 28-29. During this period it was assumed that unidirectional air mixing from the occupied zone to the plenum zone occurred due to natural convection when the mechanical system was not operating.
+
+#### FLEXLAB_X3_2mech.osm
+
+This OpenStudio model was used for the mechanical calibration from Nov 5-6, 2020. The mechanical system availability and cooling setpoint schedules in the model were changed to start on Nov 4 to allow the mechanical system to fully adjust to cooling mode during the transition period from the architectural calibration.
+
+#### FLEXLAB_X3_3cosim.osm
+
+This OpenStudio model was used to produce the `in.idf` for the co-simulation. The mechanical system cooling capacity was hard-sized to 2800 Watts to fully meet the cooling loads during the AC and DC experiments.
+
+### /weather
+
+This folder contains the EnergyPlus Weather (.epw) file created from measured site data, which is the same file used for the co-simulation.
