Principles of Retrofit

Understanding heat and moisture in your home


Description: Confused by talk of U-values and ‘breathability’ in buildings? Keen to understand how you can improve and insulate your home to make it warmer, whilst avoiding unintended consequences? Want to know enough to avoid being bamboozled, but don’t want to become a specialist? Then this course is for you!

For: Householders planning refurbishment works who would like to develop a better understanding of basic technical principles in energy efficiency and retrofit.

Benefit: Will help you to decipher some of the language used by professionals, and better understand the key considerations in ensuring a successful retrofit.

What you will learn:

  • Heat transfer mechanisms and U-values.
  • Properties and application of insulation, thermal mass, air-tightness, and ‘breathability’.
  • Understand key performance risks – cold bridging, leaks, indoor air quality and moisture.
  • Specification concerns – context and criteria.
