The general lighting load in a hotel guest room is which value?

• A. 1.7 VA/SF
• B. 1.5 VA/SF
• C. 2.0 VA/SF
• D. 1.2 VA/SF

Answer: (A)

In load calculations, you estimate lighting demand using a standard power-per-square-foot value instead of counting every fixture. For a hotel guest room, the commonly used general lighting load is 1.7 VA per square foot. This figure captures typical room lighting levels, fixture types, and usage patterns, giving a reliable, conservative estimate for sizing feeders and the service. To apply it, multiply the room’s area by 1.7 VA for the general lighting load. For example, a 350 ft² room would have about 350 × 1.7 ≈ 595 VA of general lighting load, which you then combine with other loads per code to determine the overall service size. Values noticeably lower or higher than 1.7 VA/ft² would generally under- or over-estimate the actual lighting demand in hotel guest rooms.
