Over time, building operation is degraded if systems are not properly maintained and adjusted. Cornerstone’s Existing Building Commissioning process (EBCx), often called Retro-Commissioning, uncovers costly hidden performance issues.
Our methodologies include investigation, evaluation, remediation, and verification. The benefit of EBCx services has provided owners with long-term environmental stability in many mission-critical facilities.
To address the diverse needs of different facilities, three primary types of existing building commissioning services are utilized: Retro-Commissioning, Recommissioning, and Monitoring-Based Commissioning.
Retro-Commissioning Services
Retro-Commissioning (RCx) is applied to buildings that have not been previously commissioned. This process aims to improve performance by optimizing existing systems and upgrading to more energy-efficient equipment. RCx typically involves planning, investigation, implementation, and verification phases. It addresses energy usage and performance issues, implementing measures to reduce operation and maintenance costs while enhancing system functionality. RCx is ideal for fixing inefficiencies due to design flaws, construction issues, or system degradation over time. Cornerstone’s retro-commissioning solutions uncover hidden performance issues that can result in significant cost savings.
Recommissioning
Recommissioning is for buildings that were previously commissioned. It can be part of a scheduled process or triggered by changes in building use, operational problems, or renovations. Over time, even the most efficient systems deteriorate. Recommissioning ensures these systems continue to operate at optimal performance, making it suitable for facilities experiencing performance issues or changes in operational requirements. Cornerstone’s recommissioning services ensure that building systems are fine-tuned to meet current operational needs.
Monitoring-Based Commissioning
Monitoring-Based Commissioning (MBCx) ensures ongoing energy savings and performance benefits. MBCx uses analytical software to continuously monitor critical equipment components by mining key data from the building automation system and then analyzing that data to find issues and recommend solutions. This allows for real-time detection and reporting of malfunctions, as well as ongoing observation of energy consumption and performance. MBCx is a cost-effective service that provides long-term efficiency and sustainability, maintaining the benefits of the initial commissioning process. Cornerstone’s use of advanced monitoring tools from Clockworks ensures continuous optimization and proactive maintenance.
