GBE Equations

  • Decrement Delay Factor (Equation) G#31148
  • UK Building Regulations Part L dictates attention is given to winter heating energy demands but ignores (so far) summer solar heat gains
  • How long does it take for solar radiant heat to pass through the external building fabric to start modifying the internal temperatures
  • Heavyweight construction offers a longer delay
  • Lightweight construction usually offers short delay
  • However some thermal insulation materials can provide that delay in lightweight construction
  • This equation can begin to address this issue.
  • Form Factor (Equation) G#38342
  • The ratio of external envelope to floor area or volume ratios can be used as a design driver to improve building energy efficiency
  • Simple singular cubic design is more efficient than multiple, long thin or sprawling buildings.
