IBPSA Project 1 - BOPTEST

Building Optimization Performance Tests

This repository contains prototype code for the Building Optimization Performance Test framework (BOPTEST) that is being developed as part of the IBPSA Project 1 (https://ibpsa.github.io/project1/).

Structure

• /testcases contains test cases, including docs, models, and configuration settings.
• /examples contains prototype code for interacting with a test case and running example tests with simple controllers. Those controllers are implemented in both Python (Version 2.7) and Julia (Version 1.0.3).
• /parsing contains prototype code for a script that parses a Modelica model using signal exchange blocks and outputs a wrapper FMU and KPI json.
• /template contains template Modelica code for a test case emulator model.
• /testing contains code for unit and functional testing of this software. See the README there for more information about running these tests.
• /data contains prototype code for generating and managing data associated with test cases. This includes boundary conditions, such as weather, schedules, and energy prices, as well as a map of test case FMU outputs needed to calculate KPIs.
• /forecast contains prototype code for returning boundary condition forecast, such as weather, schedules, and energy prices.
• /kpis contains prototype code for calculating key performance indicators.
• /docs contains design requirements and guide documentation.

Run Prototype Test Cases

1. Build the test case by $ make build TESTCASE=testcase# where # is the number of the test case to build from testcases.
2. Deploy the test case by $ make run TESTCASE=testcase# where # is the number of the test case that has been built from testcases.
3. In a separate process, use the test case API defined below to interact with the test case.
4. Run an example controller test:

• For Python based controllers:

  • in a separate terminal, use $ python examples/python/twoday_p.py to test a simple proportional feedback controller on the testcase1 over a two-day period.
  • in a separate terminal, use $ python examples/python/szvav_sup.py to test a simple supervisory controller on the testcase2 over a two-day period.

• For Julia based controllers:

  • in a separate terminal, use $ cd examples/julia && make build Script=twoday_p && make run Script=twoday_p to test a simple proportional feedback controller on the testcase1 over a two-day period.
  • in a separate terminal, use $ cd examples/julia && make build Script=szvav_sup && make run Script=szvav_sup to test a simple supervisory controller on the testcase2 over a two-day period.
  • once the test is done, use $ make remove-image Script=twoday_p or $ make remove-image Script=szvav_sup to removes containers, networks, volumes, and images.

5. Shutdown test case container by slecting container terminal window and Ctrl+C to close port, Ctrl+D to exit docker container.
6. Remove the test case image by $ make remove-image TESTCASE=testcase#.

Test Case RESTful API

• To interact, send RESTful requests to: http://127.0.0.1:5000/<request>

Example RESTful interaction:

• Receive a list of available measurement names and their metadata: $ curl http://127.0.0.1:5000/measurements
• Receive a forecast of boundary condition data: $ curl http://127.0.0.1:5000/forecast
• Advance simulation of test case 2 with new heating and cooling temperature setpoints: $ curl http://127.0.0.1:5000/advance -d '{"oveTSetRooHea_u":293.15,"oveTSetRooHea_activate":1, "oveTSetRooCoo_activate":1,"oveTSetRooCoo_u":298.15}' -H "Content-Type: application/json". Leave an empty json to advance the simulation using the setpoints embedded in the model.
