README: clarified repo structure

## About

This repository contains code for analysis and control of various HVAC systems at Engineering Science Building.

This repository contains code for analysis and control of various HVAC systems at Engineering Science Building. It contains:

1. Controller scripts which are run in production.

2. Jupyter notebooks used for data analysis and machine learning.

3. Python packages for data-preprocessing and defining various functions for the above 2.

## Installation and Use

### Installation for ESB condenser water control

The controller imports measurements from BDX (Buildinglogix Data eXchange), and writes a setpoint to a text file. Access to BDX requires login credentials.

The controller (`src/controller.py`) imports measurements from BDX (Buildinglogix Data eXchange), and writes a setpoint to a text file. Access to BDX requires login credentials.

To run the controller, (1) review control settings, (2) create the production environment, (3) activate it, and (4) call the script.

conda activate esb-prod

# Take action every 300s and output to out.txt. Logs default to ./logs.txt

# Uses settings from the default location (src/settings.ini)

# Writes to default logs file (./logs.txt)

python src/controller.py --interval 300 --output ./out.txt

# or, this will exit after taking one action as a test run:

# Or, this will exit after taking one action as a test run:

# Uses settings from the default location (src/settings.ini)

# Writes to default logs file (./logs.txt)

python src/controller.py --interval 300 --output ./out.txt --dry-run

python src/controller.py --interval 300 --output ./out.txt --settings ~/ESB/mysettings.ini

python src/controller.py --interval 300 --target power --output ./out.txt --settings ~/ESB/mysettings.ini
