Announcing OpenEEmeter 4.0!

Thanks to everyone in the working group for all of your hard work and input on developing the LF Energy OpenEEmeter version 4.0.

LF Energy OpenEEmeter measures the energy impacts of demand-side interventions in buildings. OpenEEmeter 4.0 provides enhanced performance of the daily model with dramatically reduced seasonal and weekend/weekday bias, along with increased computational efficiency.

Among other benefits, OpenEEmeter 4.0:

• Reduces seasonal bias in the daily model by 84%
• Reduces weekend/weekday bias in the daily model by 95%
• Runs up to 100x faster with monthly data, and 2–10x faster with daily data

Along with this release, the OpenEEmeter community is also publishing a detailed 4.0 model specification and results of thorough testing conducted across residential and commercial sectors and gas and electric fuels.

On March 12, 2024, LF Energy hosted a webinar which explained in detail how OpenEEmeter 4.0 was developed and why these advances are important for measuring the energy impacts of demand-side interventions in buildings.
