Bring Your Building Back to Life

Retro-Commissioning

Existing commissioning and retro-commissioning, two terms used interchangeably that refer to bringing an existing building to peak functionality based on current use. This service provides an process that identifies and corrects building inefficiencies that are wasting tens of thousands of dollars annually.

Retro-commissioning helps the owner identify and meet energy efficiency and performance goals through extensive review of the property and benchmarking of comparable properties.

The problem with energy waste in commercial buildings is that most of the waste is invisible in day-to-day operations (like what happens under the hood of a car). HVAC system design problems, broken dampers or valves, simultaneous heating and cooling and general unwarranted human interaction with temperature controls, all can create significant energy waste. 

Retro-commissioning can be the most important building efficiency process implemented for your buildings. These systematic processes provide a detailed engineering evaluation focused on energy savings, with emphasis on low cost or no cost energy saving measures (generally < 2 years simple payback) to combat building waste and identify all measures that meet the long-term plans of the owner. Retro-commissioning goes beyond day-to-day maintenance by addressing high energy costs and resolving operational problems by conducting a thorough assessment of existing mechanical HVAC systems, lighting, service water systems and automatic controls.

Jereme Nollett

Senior Commissioning Manager

Leveraging his years of experience, Jereme specializes in building performance optimization, life- cycle cost analysis, cost-benefit analysis, carbon footprint reduction and energy conservation measures. He has a diverse background in system design, new and retrocommissioning, energy management, and test & balance with apassion for sustainable design and building optimization, resulting in an extensive understanding of MEP systems, their functionality and interaction with one another.

Andrew Shaver

Sr. Commissioning Specialist

Andrew brings a different viewpoint to the commissioning process. Coming from a background of facilities management and program management for construction activities in multi-site organizations, Andrew has spent time across the table as the owner. He has lead activities such as directing design decisions, operating procedures, leading multiple design-build projects, and understanding the cost associated with mechanical systems and their requirements. Over the last decade, he has worked to institute new and retro-commissioning in the facilities he served and advocated for optimization to prolong the life of mechanical systems, reducing operating costs, and aligning real-world metrics with design intent for optimal occupant comfort and usability.
