The Copper Connection Podcast – Season 2, Episode 10

On this episode of The Copper Connection Podcast, host Chris Bailey explores the fundamental heat principles that shape modern construction and building services engineering. From conduction, convection, and radiation to thermal conductivity, U-values, and condensation control, we'll break down the science behind how heat moves through buildings — and why understanding these principles is critical for creating energy-efficient, sustainable, and healthy living spaces.

You'll discover how heat loss occurs through walls, roofs, windows, and ventilation systems, and learn the practical solutions that reduce energy consumption and improve thermal performance. Plus, we'll examine how moisture and condensation affect construction materials, explore thermal expansion calculations, and look ahead to the future of sustainable heating systems including heat pumps, photovoltaic cells, and combined heat and power (CHP) technology.

Whether you're a construction student, building services engineer, architect, or trades professional, this episode equips you with essential knowledge about thermal dynamics, Building Regulations Part L compliance, and the renewable energy solutions transforming the built environment.

• The three mechanisms of heat transfer — conduction, convection, and radiation — and how each affects building performance
• How to reduce heat loss through cavity wall insulation, double glazing, roof insulation, and draught-proofing
• Understanding U-values, R-values, and K-values and how they guide insulation selection
• Condensation causes and prevention — why poorly ventilated buildings develop moisture and mould problems
• The damaging effects of moisture on timber, plaster, steel, and electrical systems
• Thermal expansion in construction and why expansion joints are essential
• Sustainable heating systems — photovoltaic cells, heat recovery ventilation, and heat pumps
• Passive heating and cooling strategies — building orientation, natural ventilation, and solar shading
• Combined Heat and Power (CHP) technology and reducing carbon emissions by up to 30%
• Future-proofing buildings for climate change and temperature extremes
• 
  

Whether you're studying construction science, working on retrofits, or designing net-zero buildings, this episode delivers practical insights into thermal principles that determine comfort, performance, and sustainability.
