We spent a little time with Stewart Little, a former architect who's been working to support energy efficiency and retrofit in the built environment for more than 20 years.

With IRT Surveys he has led a business that uses thermal imaging to highlight energy saving issues in the built environment and an online platform that uses property data that shows its users how to save energy and access funding.

Stewart was excellent value, with plenty to offer from years of experience and his  Rockstar-related origin story, but we were really keen to speak with Stewart because his story highlights just how much things have changed for the green building sector, and how much opportunity is being recognised.

We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.
