Within a commercial office building of 2300 sq m (25000 sq ft), how many building automation system (BAS) devices are required?

50 devices would represent one device per 500 sq ft, which is too sparse for adequate BAS coverage in a commercial office building.

75 devices falls below the standard density threshold and would not provide sufficient sensor and control point coverage for a building of this size.

The standard rule of thumb for BAS device density in commercial office buildings is approximately one device per 250 sq ft. Applying this to 25,000 sq ft yields 100 devices (25,000 / 250 = 100), which aligns with ASHRAE and industry guidelines for adequate monitoring and control coverage.

125 devices exceeds the standard density guideline and is not the recognized benchmark ratio for this floor area.

150 devices significantly over-provisions the building beyond standard design ratios and is not consistent with established BAS density guidelines.
