Operations and maintenance (O&M) of existing buildings get short shrift in the green building community.

But greening existing buildings has immediate benefits for owners, occupants, and the planet. And new buildings that look good on paper need a successful handoff to operations. That often includes a year or more of working out the kinks in sophisticated energy systems.

Sustainable O&M encompasses:

  • site maintenance, landscaping, and rainwater management

  • water efficiency

  • energy efficiency, including auditing and commissioning

  • environmentally preferable purchasing

  • waste management

  • indoor air quality management

  • green cleaning
