Three factors are used to express the efficiency with which teaching accommodation is used.

Space efficiency has implications for used workplace income and total space requirements. Both factors impact directly on the financial viability of courses in colleges and universities.

The calculation of the three indices, based on a space utilisation survey, are indicated in the following table.

The table provides the basis for the plotting of room frequency, seat occupancy and space utilisation levels.

The graph shows current average space efficiency levels. The data, adjusted if appropriate, provides the basis for space modelling.

Space efficiency has implications for used workplace costs and total space requirements. Both factors impact directly on the financial viability of courses and institutions.
