Assessment of user satisfaction of restrooms with existing toilet fixtures and new low consumption fixtures

This research in Langford Building 'A', Texas A&M University, is an attempt to determine the user satisfaction of the new, low consumption toilet fixtures and lavatory valves. 253 surveys were given to the subjects, during the four phases of upgrading the restroom fixtures, to find and compare user satisfaction in each phase. The four phases were:

1. The as-is condition of the flush valves and the lavatory valve.
2. Low consumption manual flush valve and low consumption manual lavatory valve.
3. Old style low consumption automatic flush valve and low consumption automatic lavatory valve.
4. Low consumption manual flush valve and low consumption automatic lavatory valve.

The survey analysis for the building showed a positive response from the users for the low consumption valves, but not for the automatic valves, as they did not function as they were expected to.
