There are numerous studies that explore the causes of energy performance gaps in residential properties. Even the best designs can struggle to translate into real world conditions. On paper they may seem highly efficient and sustainable. However, in practice they can suddenly be far worse. There are several things to consider here, but one of the main factors to examine is occupant behaviour. Let’s have a look, then you can rely on us if you want to work with a fantastic architect in London.

The problem

It’s wonderful to create great designs and have models for energy efficiency. However, they may not accurately consider the behaviour of occupants. In fact, they will likely think of behaviours in very simple, idealistic terms. It can easily mean the actual performance is very different. As a result, the homes can consume more energy and have higher bills than planned.

In the worst cases, homes can be several times less efficient than the design predicted. This is a massive performance gap. Sadly, while it is possible to improve designs retrospectively, it is generally more difficult and more expensive.

What to consider?

If you want to reduce the performance gap, it is important to understand real-world occupant behaviour. Don’t simply think about the ideal scenarios. Look at what the occupants will actually be doing on a day to day basis. Remember you can always rely on us when you want to work with a leading architect in London.

There are a number of key things in particular to look at. Firstly, how will occupants behave in terms of opening windows? If they like to leave them open all year round, even in winter, you need to factor that in. It can have an impact on heating and cooling costs.

Next, consider shading. We’ve seen this year that the majority of homes in the UK aren’t good at dealing with intense hot weather. One way to tackle this is using window shades or even closing blinds and curtains to reduce solar gain. However, you need to make sure occupants will actually be doing these things; don’t idealistically think they will when they may not and simply use fans or air con more often.

It’s also vital to get a good idea of how much water people are actually using. You can design homes with sinks, toilets, and showers that are very efficient and minimise water use. However, what if occupants prefer baths or take more long showers? What if they leave the tap running while washing up or brushing teeth? All of this leads to the performance gap.
