EcoHome Lab: Calculating Metered Energy Savings (MES) from retrofit

***

This session will focus on the latest work on the development of [Metered Energy Savings](https://carbon.coop/2024/02/retrometer-project-why-metered-energy-savings/) (MES) methodologies to calculate the impact of energy efficiency interventions in the UK. MES approaches compare energy usage post-retrofit with a “counterfactual” – the energy the household *would have used* in the same period had the retrofit not happened.

We’re pleased to be joined by **Connor Galbraith, Data Scientist at [Energy Systems Catapult](https://es.catapult.org.uk/project/retrometer/)** who has been leading the work on how this Counterfactual is generated in the recent [RetroMeter](https://es.catapult.org.uk/project/retrometer/) project. The work draws extensively on work done internationally via LF Energy’s [OpenEEMeter](https://lfenergy.org/projects/openeemeter/) project.

Regular attendees will be familiar with MES approaches from our previous sessions on [CalTRACK/OpenEEmeter](https://www.meetup.com/eco-home-lab-manchester/events/282990686/) and the launch of Carbon Co-op’s own MES web tool, [PowerShaper Tracker](https://tracker.powershaper.io/).

Connor will be discussing:

* How the models work
* In what circumstances different models can be used
* The performance (accuracy, bias) of different models
* Data sources and data accessibility issues for data needed for different models

EcoHome Lab is a [Carbon Co-op](https://carbon.coop/) initiative, often working together with [OpenEnergyMonitor](https://openenergymonitor.org).

Topics will include:

• Home energy monitoring.

• House energy performance assessment

• Sensors – electricity, gas, temperature, humidity, air quality…

• User interfaces, dashboards

• Smart houses and automation

• Aggregation of data sources

• Taking the power back! – Making better use of the surplus power we generate

**Who is it for?**

• Anyone with skills in physical electronics, web development or programming who wants to use that knowledge to reduce energy and carbon!
