BRCM Toolbox

What is it?


The Building Resistance-Capacitance Modeling (BRCM) Matlab Toolbox facilitates the physical modeling of buildings for MPC. The Toolbox provides a means for the fast generation of (bi-)linear resistance-capacitance type models from basic geometry, construction and building systems data. Moreover, it supports the generation of the corresponding potentially time-varying costs and constraints. The Toolbox is based on validated modeling principles described in [1].

Features

 

  • Generation of a discrete-time bilinear state-space model of the building

  • Loading from / writing to strictly structured building data files

  • Visualization of the building

  • Programmatical parameter manipulation

  • Providing functions to generate time-varying costs and constraints for the MPC optimization

  • Simulation of the model

  • Input data generation from EnergyPlus input data files

Installation

The Toolbox package installer tbxmanager has a broken link which we have not been able to fix. So until further notice a zip archive of the BRCM toolbox is being made available via the following download link: Download BRCMToolbox_v1.03.zip (ZIP, 2 MB).  The original tbxmanager installation instructions and links are provided below as they maybe in useful in the installation process.

The BRCM Toolbox is available via tbxmanager, which simplifies the installation and update of freely available Matlab toolboxes.

To install the BRCM Toolbox for the first time, follow these steps in Matlab:

  1. Install tbxmanager as described on the external page webpage.
  2. Install BRCM by typing: 
    tbxmanager install brcm

  3. To check for updates type:
    tbxmanager update

 

Documentation

A BRCM Toolbox Manual is available as a Download downloadable PDF (PDF, 1.2 MB).

The most detailed description of the modeling methods can be found in the Ph.D. thesis of David Sturzenegger [3].

Within the OptiControl-II project (website, report), these algorithms have been used to a create model that was experimentally validated and successfully used over multiple month in the MPC on a real fully operated office building.  An analysis of the results of this project are given in:
