The virtual environment made it clear how a design detail or proposal would look, and fit, as you can see from the images.

For example, low density means that in order to harness enough energy to power the UK, we would need to build a solar farm of an impossibly large size.Renewables also have problems to do with dispatch power and consistency, as well as challenges with site locations.

Last summer, which was a still and cloudy one, wind and solar simply didn’t generate as much energy as we would have liked, and at this stage, all of the easiest, most suitable sites (the ones which may have access to transmission, and are very suited to wind and solar projects), have already been taken.. Interestingly, while energy systems modelling for wind and solar power often shows a hockey stick curve, as if the upward trajectory of deployment will continue undeterred, in actual fact, this isn’t the case.Over time, we find that the hockey stick turns into an S shaped curve instead.In other words, renewables are getting progressively harder to do.

In fact, the more we build, the more challenging renewable energy becomes..In addition, public resistance to building out an ever increasing amount of infrastructure is mounting, and this resistance is happening before the conversation even turns to transmission, which, Gogan says, is very difficult to build, as it’s hard to make the case that people will directly benefit from things such as the creation of jobs.

This results in real challenges over land use.. And yet, the net zero transition is undoubtedly going to require a large amount of new infrastructure to be built, raising big questions about where to build it.

Gogan points out that it really doesn't matter how cheap something is, if you can't build it in the first place.For tall buildings this can lead to very high stacks that would impact the building’s appearance and will likely require Planning Permission.

For example, a 10-storey office building with an average floor to floor height of 4m would require a stack 10m tall (nearly 3 storeys.)There are a few ways to challenge this, including CFD (Computational Fluid Dynamics) modelling and the use of alternative discharge stacks (e.g.

strobic fans), which may be necessary for some office to lab conversions.Of course, local standards elsewhere will vary.. 5.
