Corporate Building Services, Inc. joins a growing number of premier commercial cleaning organizations to certify to the ISSA Cleaning Industry Management Standard (CIMS) and CIMS-Green Building (GB).

Dallas, Texas, USA, May 2021 — ISSA, the worldwide cleaning industry association, announced today that Corporate Building Services achieved ISSA Cleaning Industry Management Standard (CIMS) and CIMS-Green Building (GB) certification.

Compliance with the standard shows that a cleaning organization has the systems in place to deliver consistent, professional services designed to meet customer needs and expectations, and is prepared to deliver a comprehensive green cleaning program based on LEED EB: O&M green cleaning criteria. CIMS and CIMS-GB certification are required in many cleaning service bid specifications as customers look for an effective way to identify high-quality providers committed to customer satisfaction.

“One of the benefits of the pandemic was the realization that customers need and want cleaning companies that offer the highest level of quality cleaning services,” says Sarah Boltz Byrne, President of Corporate Building Services, Inc.

Independent, accredited assessors verify CIMS and CIMS-GB certified firms meet the industry standard for:
• Quality systems
• Service delivery
• Human resources
• Health, safety, and environmental stewardship
• Management commitment
• Green Building

Recently, CIMS-GB became a direct compliance option to meet the green cleaning policy prerequisite of Version 4 of the U.S. Green Building Council (USGBC) revised Leadership in Energy and Environmental Design for Existing Buildings: Operations and Maintenance (LEED EB: O&M) rating system.

“CIMS-GB certified organizations are subject to a rigorous third-party assessment, which provides customers with the assurance that their cleaning service provider is committed to effective management and is prepared to partner with them in the LEED certification process” explains Todd Clark, Chief Operations Officer, Corporate Building Services, Inc.. “Inclusion of CIMS-GB allows us to directly assist customers in earning credits toward LEED recognition”

About CIMS and CIMS-GB

The ISSA Cleaning Industry Management Standard (CIMS) and CIMS-Green Building (CIMS-GB) set forth a management framework designed to assist building service contractors and in-house cleaning departments to develop and maintain quality, customer-focused organizations, capable of delivering a comprehensive green cleaning program based on LEED EB: O&M green cleaning criteria. The standard is nonprescriptive, meaning that each organization has the flexibility to choose the most effective ways in which to meet its requirements. CIMS and CIMS-GB were created through a true consensus-based process that brought together representatives of the cleaning, facilities management, and purchasing communities. ISSA speaks at numerous facility management and purchasing industry events throughout the year to outline the value of working with CIMS and CIMS-GB certified cleaning companies as well as certifying in-house operations.
