Loanstar data handling and analysis software for measuring building energy data

This paper discusses the data handling and analysis software that has been produced as part of the Texas LoanSTAR program, a $98.6 million revolving loan program for funding energy conservation projects in state agencies. In this paper an overview of the different facets of data management for monitoring building energy data is presented. LoanSTAR software that is now available for others to use is also discussed, including: PC-based MS Windows 3.1 software for analyzing before-after energy use data (EModel), software for viewing time-sequenced, temperature dependent trends (Animate), software for viewing 3-D images (Look3D), software for viewing solar data (Solrpath), and software for viewing real-time logger data (Monitor). The Energy Systems Laboratory (ESL) has also developed a combined, general purpose software package for polling, archiving, analyzing and reporting building energy data from multiple sites (MAP).
