In the north of England, researchers are looking at ways to make the homes we already live in as efficient and sustainable as possible.
The University of Salford's Energy House project has taken a pre-1919 Victorian era property from near the university and re-built it brick by brick inside what the team say is "the only full-scale building in an environmental chamber in Europe."
By controlling the environment and climate inside the chamber, the researchers can undertake scientific research that it's hoped will help improve the efficiency of "hard-to-treat properties."
As the amount of new housing stock being built in the U.K. fails to keep up with demand, the retro-fitting of older homes so that they become more energy efficient is becoming increasingly important.
The chamber is crucial to the project.
"We can control the variables, and we can do things in the house that wouldn't be possible with a person's home, we have hundreds and hundreds of sensors – we can add sensors, take sensors away – but also, we can control the weather," William Swann, from the University of Salford, told CNBC's Sustainable Energy.
