We prioritize transparency and flexibility, using digital tools to keep stakeholders aligned and catch issues early, when they’re most cost-effective to resolve. From defining goals and reviewing designs to overseeing testing and training your staff, we deliver a high-performing facility with reduced costs, improved reliability, and genuine peace of mind.

The result: a high-performing facility with reduced costs, improved reliability, and genuine peace of mind.

Retrocommissioning

Retrocommissioning is Mazzetti’s solution for unlocking performance and energy efficiency in existing facilities, regardless of age or condition. As your trusted ally, we assess your documentation and system operations, then work alongside your facility staff to analyze operational data and pinpoint opportunities. We focus on practical, actionable solutions, from simple adjustments to advanced controls, that boost occupant comfort, reduce energy waste, and lower operating expenses.

Guiding you through scoping discussions to set priorities and payback goals, we implement energy-saving measures with immediate impact and identify long-term capital projects backed by energy audits at every depth. With experience in LEED for Existing Buildings and ongoing measurement and verification, every project is tailored to your sustainability goals, so you see real, documented results and maximized building assets.
