Diversity factor

BG 88 Commissioning Responsibilities Framework, by Matt Lowry, published by BSRIA in January 2025, defines diversity factor as: ‘The ratio of the theoretical maximum demand on all terminal units at any one time to the summation of the design maximum duties of those units. The diversity factor is often quoted as a percentage.’
