Intelligent Building Agents Project

In the U.S., commercial buildings are responsible for approximately 36 % of total energy consumption, and the heating, ventilation, and air-conditioning (HVAC) systems make up about 52 % of that total. Improving building operations can significantly reduce the amount and cost of the energy used in the commercial building sector. The Intelligent Building Agents (IBA) project is part of the Embedded Intelligence in Buildings Program in the Engineering Laboratory at the National Institute of Standards and Technology (NIST). A key part of the IBA Project is the IBA Laboratory (IBAL), a unique facility consisting of a mixed system of off the shelf equipment, including chillers and air handling units, controlled by a data acquisition system and capable of supporting building system optimization research under realistic and reproducible operating conditions.

Data

The IBAL Database contains the values of approximately 300 sensors/actuators in the IBAL, including both sensor measurements and control actions, as well as approximately 850 process data, which are typically related to control settings and decisions. Each of the sensors/actuators has associated metadata. Data are collected every 10 s. The data can be access as individual sensor data or as all the data from a specific test. For example, searching for "DOE Formal Testing" in the Experiments page will bring up tests run as part of a 2019 DOE BENEFIT project. Data can be isolated by subsystem as well. If you select Chiller1, for example, all sensors directly related to Chiller1 are listed. The time series data are shown as plots and can be downloaded as csv files for use offline.

Software

This repository contains scripts developed as part of the IBA project for data processing and model development. They are organized based on the equipment they model, the publication they support, or another keyword. When use in support of a publication, the publication or a link to it are included in the folder. Each script has different software requirements. The languages include MATLAB, Python, and FORTRAN.

Research Topics

The folders in this repo are organized by research topic. They contain README files to explain their contents in more detail.

  • IBASIM: publications and software related to the simulation model of the IBAL
  • Comparison of ice-on-coil thermal energy storage models: publications and scripts related to the development of machine learning models of the ice-on-coil thermal energy storage system in the IBAL
