1.3.18 Wash hands with cold water instead of warm water

Description

Although the perception that hot water is more hygienic is based in some factual evidence, there are few, if any hygienic benefits, of using warm or hot water to wash one’s hands. It is true that heat kills bacteria; however, the level of the heat required to neutralize pathogens is beyond what is considered safe for prolonged human contact.

Benefits

  • Energy savings to heat the water

  • Avoid wasting water while waiting for the running faucet to heat up

Limitations

  • Occupant acceptance

Economic assessment

Zero investment.
