It is a truth universally acknowledged that there is a skills gap among heat network designers and that by filling this gap we will improve network performance. In other words, if we provide more training to engineers, heat networks will get better.

There’s no doubt that some heat networks are plagued by performance problems, costing customers too much and delivering poor quality of service. But can this be fixed with additional training for consultants? Are heat networks really so complicated that engineers already trained to master’s degree level can’t design them well?

In fact, the skills gap is a red herring and providing more training to engineers won’t help. Here’s why:

Capital contributions, the payments made by ESCOs to developers in exchange for long-term concession agreements, are a hangover from the days when everyone thought onsite generation would be highly profitable.

We’ve since discovered that it isn’t as lucrative as expected. Nevertheless developers continue to demand these upfront payments, leading to higher standing charges, longer contracts and unhappy residents. Isn’t it time for the practice to stop?

At Guru Systems, we’ve been trialing a way of coordinating our efforts to achieve our company objectives called OKRs (Objectives and Key Results).

We’re still fine-tuning, but our experiment over the last seven months has shown how hugely effective OKRs are in aligning our teams and staying focused on the important things. In this post, I’ll explain how they work and what we’ve learned along the way.

Heat loss headaches

This blog was originally posted on networks.online.

Any heat network operator or customer will tell you that heat losses matter – a lot.

Losses that go unchecked can easily double the cost of heat on the network. But while everyone agrees it’s hugely important to limit losses, the way we talk about heat loss is all wrong. And heat network performance is suffering as a result.

In 2016, the heat sector finally recognised the importance of performance data. Helped by companies like Guru, heat network operators began to obtain energy performance data from their networks.

The data sent shockwaves through the industry as many realised that their networks are not performing anything like what was promised, largely due to shortcomings in design and commissioning.

Using this information, the operators of these poorly performing networks could finally attach precise numbers to their long-held suspicions: that losses are high, that heat costs too much and that service can be unreliable. Of course, customers on bad networks already knew this from their own experiences of high bills, cooking corridors and intermittent heating and hot water.

As this awakening gathers pace, a key trend for 2017 will be the move towards quantified performance. Armed with clear requirements, clients will be more specific about what they want, and use measurement and verification to ensure they get it. ESCOs, having had their fingers burnt, will no longer be content to sample the performance on a limited number of dwellings before adopting a new network. Instead they will use performance data to verify that 100% of equipment in homes has been properly commissioned. In short, networks won’t be allowed to go into operation until they work as intended.

This change in approach will have huge implications for the industry.

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.

In the previous post, I described the characteristics we’d want to see in a competitive heat market. In short, we want many heat networks of varying sizes to function as markets that are fast, efficient, accessible, cheap and decentralised. I also tried to show that simply copying the electricity market for heat is a bad idea.

So what model should we adopt? In this post, I propose a new model based on blockchains, the technical innovation that underpins cryptocurrencies like Bitcoin and Ether.
