How it works

Our Approach


First the energy demand needs to be reduced through better building fabric and low energy components.


Using thermal mass, heat and electricity storage to balance the needs of the home throughout the day and night.


Use natural energy sources to generate energy where possible, whilst simultaneously creating a great place to live.

creating a blueprint for zero carbon living.

Sero Projects understands the challenges of development because we do it too. Sero Homes, our sister company, builds and runs zero carbon homes for future generations. So when we’re advising you on construction details, site programming or specialist tendering packages, it’s probably drawing on the experience of having already done it for ourselves.

Our homes

We’ll look after your residents for you!

Sero Projects partners with our developers and landlords for the long term, passing over to Sero Life as the energy service company for the home. This means, unlike consultants or specialists at the construction stage, we stick around for the long haul. Your homebuyers or tenants become our customers, and that means the energy systems we helped you install become ours to run. And in the unlikely event that they don’t work, they’re ours to fix.
