➙A new open-source software tool that uses automated calibration
techniques to tweak commercial
and residential building energy efficiency
soft ware models to match measured data
is now available.
The Autotune code, named after the
audio software known for adjusting
pitch in music recordings, can perform
no-touch audits, provide guidance for the
most efficient retrofit procedures, and
allow other data-driven decisions to be
made for buildings under 50,000 square
feet, which are too small to be served by
traditional building modeling systems.
The code was developed by research-
ers at the Oak Ridge National Laborato-
ry’s Building Technologies Research and
Integration Center, who used DOE su-
percomputing resources to perform mil-
lions of energy modeling simulations for
a variety of building types. This allowed
the team to find techniques and computa-
tions that help a building’s performance
match measured data. Rather than
requiring a large number of adjustments
and modifications to be made manually,
the software is designed to automatically
optimize building parameters to save
money and energy.
The software is available free online at
AUTOTUNE, an open-source building modeling tool named after the popular pitch-adjusting
software used in music production, is now available free online.
