New buildings in the UK consume far more energy than intended by their designers – up to 10 times more according to an Innovate UK study. This performance gap doesn’t arise because we lack technology. Studies by the UKGBC and others conclude that it’s the result of failings throughout the project lifecycle, from concept to handover.

Performance gaps may arise because clients are unclear about what they want; project teams don’t understand the impact of their design choices; contractors substitute products and materials on the fly and then install them poorly; or quality assurance is lax, with employers’ agents either blind to the problems or willing to let shoddy work escape their net.

There’s no doubt about it – we’ve got trouble right here in the UK building industry. But innovation on its own won’t solve the problem. The Internet of Things isn’t coming to the rescue. Because the performance gap isn’t a technology problem – it’s a problem of people, information and accountability.

We’re often told that energy data is valuable. Less often discussed is the fact that handling data can be risky. But just as not all data is equally valuable, some types of data are riskier than others. The trick is to maximise value while minimising risk.

Operational data from onsite energy systems (like heat networks) is extremely hard to come by. Very few people manage to get hold of it, and those who have it rarely share.

What are the typical loads in dwellings? What are the network losses? Do customers all demand heating at the same time or are demand events spread out?

Who knows? Engineers don’t stick around and find out how their designs work in real life; ESCOs hold their cards close to their chests; and many landlords fail to extract or make use of their own data.

This dearth of data has hamstrung the industry at a time when it should be racing ahead. It’s one of the biggest reasons why, when it comes to energy performance, we’re just not getting better fast enough.

In late 2014, when DECC put out a call for proposals to improve heat networks, we saw a chance to unlock some of these data silos and accelerate development of the heat market.

I’ve been invited to do a short talk at a UK Trade and Industry event for investors in heat networks, giving an overview of innovation in the sector. This gives me an excuse to do some research and summarise it in this post – and also an opportunity to ask readers what I’ve missed.
