THE LESS ENERGY it takes to heat, cool and run your home, the lower your bills will be – and the lower your impact on the environment will be too.

This is a simple enough concept in principle, but in practice, things can get a bit more complicated, particularly when you introduce terms like ‘deep retrofit’ (a whole-house renovation to increase your home’s energy efficiency) or ‘U-value’ (the rate of heat loss through a material like glass or concrete).

Whether you’re planning major renovations or are just trying to be more mindful of your daily energy usage, it can be helpful to understand some of the trickier terms from the world of energy efficiency.

As part of our House2GreenerHome series with the Credit Union, we asked architect Róisín Murphy to decode some of the more common jargon, helping people on their journey to creating cosier and more sustainable homes.
