If you are serious about the energy efficiency of your buildings, there’s a game-changing term you’d better get to know: phase change.
Phase-change materials, or PCMs, are being applied to building products at a rapidly accelerating pace. The substances can store and release huge loads of energy as they turn solid or liquid. No, don’t worry; your building won’t melt. The trick is using natural PCMs such as wool insulation, paraffin and clay finishes, which store energy to heat or cool structures a tiny bit across large surface areas. Even better, use super-duper engineered PCMs in concentrated doses within novel building products.
