This laboratory in England - the Energy House Labs - can create various weather conditions to research energy use in homes.
According to recent government laws, carbon emissions from new houses need to decrease by 2025.
Labs like these can help the building industry develop quickly, says Labs' director, Professor Will Swan.
Temperatures within the laboratory can be made to fall to -20°C or rise as high as 40°C.
There's a snow machine, as well as a wind machine.
The test houses in the centre might look fairly ordinary, but inside it's a very different story.
The buildings are packed with new technology, to help discover ways to reduce energy costs and become more environmental.
Technical director Tom Cox is very excited by the project.
They've had the opportunity to work with some amazing new technological products.
For Cox, the main benefit is that all the different technologies can work together as one system.
As energy costs rise and climate change issues worsen, this research is necessary.
It could be an important step in reducing carbon emissions.
