Carbon Co-op

EcoHome Lab: Introducing the Home Energy Model (HEM)
2026-03-12 18:00 - 19:30 (Africa/Abidjan) | Online event
RESCHEDULED from February due to illness.
For over 30 years the methodology used to gauge the energy and carbon performance of UK buildings has been the Standard Assessment Procedure (SAP), but all that is about to change. Over the past few years Government has been working with building professionals to develop the Home Energy Model (HEM) which is due for publication shortly.
We are very pleased to be joined by Marianne Heaslip, the Technical Director of People Powered Retrofit who has been working as part of HEM’s quality assurance and verification team. The session will introduce the key principles of the new methodology, how it differs from SAP and what that means for how we model buildings to inform regulation (like EPCs) and design.

Now in our regular monthly slot – every second Thursday of the month. 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.
Unless there’s a specific title to the session, it means we have no scheduled speaker and it will be an open session. We welcome contributions.

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!
• There will be open space for small groups to focus on adding new sensors or hacking the user interface, there will always be a ‘newbies’ group for people interested in finding out more.

EcoHome Lab: Regional data for accurate carbon footprinting
2026-06-11 18:00 - 19:30
***
At Ecohome Lab we’re all about the carbon savings, but how we calculate our carbon can lead to very significant over and under estimates. This can in turn lead us to make retrofit decisions which won’t deliver our desired outcomes.
In this session we’ll go through the three valid methodologies for calculating your homes carbon emissions, their level of accuracy and why the differences between them can be so significant. We’ll also provide you with the datasets to do your own comparison on your own home.
