EcoHome Lab: Using CO2 data to quantify ventilation rate

14th March, 6:00 pm7:30 pm

***

We are extremely pleased to be joined by Dr. Jess Few (UCL) and Trystan Lea (Open Energy Monitor) to discuss the potential of CO2 sensing to quantify ventilation rates in domestic properties.

Jess – is now a Research Fellow specialising in UK household energy consumption, but during her PhD she developed a method for measuring ventilation rates in occupied homes, based on the tracer gas decay technique. As part of the research she developed algorithms to identify periods when a dwelling is unoccupied and then identify and analyse periods of CO2 decay for ventilation rate analysis – this code is all released under an open source license.

Trystan – Is co-founder of Megni & OEM, who not only builds a variety of tools to model, plan and measure domestic decarbonisation but uses his own house as a case study. For the last few months Trystan has been experimenting with adding CO2 tracking to his monitoring system to track air change rates within Emoncms. He’ll take us through his results so far and how others might replicate it.

This is a really live area of research and exploration, so there will be plenty of time for discusssion, if you’re working on your own experiments please do come along and share your findings.

In our regular monthly slot – every second Thursday of the month – EHL is a hangout for people taking control of their home energy usage and generation. We use open-source hardware and software to gain a better understanding of energy in our homes, how to make the best use of the energy we generate and reduce energy wasted.

**Catch up** on some of our previous sessions and presentations.

This is a [Carbon Co-op](http://carbon.coop/) initiative, working closely with OpenEnergyMonitor and others that work to code us a better world.

**Regular EHL topics 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, data analysis or programming who wants to use that knowledge to reduce energy and carbon!
