Using machine learning to eliminate wasted energy from buildings

Small Power isn't small any more. Dan Williams and Josh Eadie from Measurable Energy for their Green Tech South West Talk: using Machine Learning to eliminate waste from buildings

Green Tech South West welcomes Dan Williams and Josh Eadie, both Co-Founders of, to tell us about their mission to create energy efficient workplaces that inspire people to positively impact energy consumption and environmental sustainability.

To do this, they’ve built and developed specific IoT and Machine Learning to automatically identify and eliminate wasted energy and emissions from Small Power energy loads.

Small Power, sometimes known as Plug Load power, accounts for up to 40% of a commercial buildings energy consumption. It’s made up of the unfixed devices, products and appliances commonly plugged in to the electricity network in an office environment.

Up to half of all Small Power can be easily classed as wasted energy use, creating GHG emissions for no reason. For example unused devices which are plugged in but not used or are running needlessly. Until now, there’s been no meaningful way of monitoring this energy load, let alone controlling it.’s approach is to use technology to seamlessly enable energy efficiency without adding to people’s job lists or interfering with a building’s occupants.

About Dan

Dan is co-founder and CEO of, he’s been working in the environmental technology sector since 2009 when he undertook an Engineering Doctorate (EngD) with Microsoft to help define ways to calculate the environmental impact of software services. Using the output of his EngD, he began his first company in 2013, Qingtech, working with the BBC, Google and others to help them rigorously calculate environmental impacts.

In 2018 Dan started to fill in the gap of not enough action being taken to make a difference to sustainability at the simplest level, turning things off when they don’t need to be.

About Josh

Josh has led the technical development as CTO from the back-of-the-envelope calculations, to first prototype, through successful deployment of over 25 UK pilot trials with grant funding – to the current position – receiving significant scale-up funding in late 2021!

Josh has always had a passion for the intersection between hardware and software solutions and looks forward to bringing experience from his EngD in Machine Learning into the environmental sustainability industry.

Coming shortly.

Links and resources

Community 60 second intros

An opportunity for you, our community, to (very quickly) share something with the rest of us. This can be anything from a green tech project or initiative you are working on, a request for help or guidance or even some knowledge/resource you’d like to share with others.

Neil Clark – Co-chairs the BIMA sustainability council – an membership organisation for UK agencies. They’ve been busy putting out a number of initiatives including an open letter to the Government asking for a Green Tax Benefit. They’re suggesting that if companies do a number of climate positive things, there could be a possibility for a green tax benefit similar to research and development tax break.

Neil has also collated a list of employee benefits which are planet focused (pension schemes, electric vehicle schemes, investing in windfarms etc.) which employers could roll lout right now and give their employees access to without much financial output. Be sure to check them out!

Tim Edwards – Designs products to get people faster onsite help in an emergency (vehicle theft, home break-ins, medical emergencies). He’s looking to design and manufacture a range of products while creating a net zero, ethical, sustainable and transparent supply chain.

Alongside this, he’s looking to re-start the Bristol circular economy group. Currently involved in a society of 250 members world wide with a shared goal of product society fit – people who are creating products that will benefit society, the environment and individuals etc. If anyone is interested in what Tim is involved with please get in touch via his Linkedin.

Andrew Brennwald – Relocated to the UK from the States where he volunteered for tech, diversity and inclusion initiatives for around 5 years. Now in the UK, he’s starting a game studio that makes games about environmentalism, combining environmentalism, education and technology to produce games with the aim of bringing brilliant minds into climate awareness space through entertainment.

Tom Finn – Working on a project called ‘Skills for Clean Growth’ supporting SME’s in the West of England region to help them gain skills around sustainability. It’s a fully funded project that has some really good workshops coming up. They’re working with some really interesting consultancies and academics to bring you relevant content. So anyone who’s keen to get some support please get in touch with Tom!
