(Applying correction factors for ambient temperature, grouping, and thermal insulation) 📌 Standard Diversity Rules

Whitfield's text utilizes demand diversity to ensure buildings do not waste money over-engineering their grid service:

Lighting Loads: Households are generally rated at 66% of total demand, while small retail stores are calculated at a steeper 90% demand factor.

Institutional Blocks: Schools and offices usually apply a broad 40% demand factor to their overall system profile due to low simultaneous massive load use.
