|Class Activities:||1 hr|
Class Description: Participants explore the underlying rationale for managing water use in a facility and develop their knowledge of water efficiency and the water assessment process. This class prepares the participant to take an active role in managing water use in their facility. One day.
At the completion of Water Efficiency for Building Operators, a participant will:
- Develop an action plan for applying water efficiency concepts back on the job.
- Discuss the rationale of using water efficiently.
- Discuss how national industry standards, federal and local requirements, guidelines and programs address water efficiency.
- List the phases in a facility water assessment.
- Discuss case studies and resources for water efficiency technologies and best management practices.
- List sources of water and water using equipment in commercial and institutional facilities.
- Describe common water efficiency opportunities for at least three types of equipment or processes.
- Conduct a walkthrough audit and discuss efficiency opportunities with colleagues.
- Describe strategies for facility water reclamation and reuse.
