Typical Retrocommissioning Projects

Buildings that benefit from retrocommissioning include HVAC-intensive facilities like hospitals, schools, labs, data centers, and office buildings. Because automated control systems are often hidden from sight, they may be ignored until there’s a problem—and thus can fall out of tune. When multiple control systems are centrally located, it’s also easier for a commissioning agent to find opportunities for savings. Top candidates for retrocommissioning include:

  • Buildings with central boilers, chiller plants, or underutilized automated control systems
  • Buildings with unexplained increases in energy use or occupant complaints about comfort
  • Buildings that have recently shifted to a new use or type of business activity

How to Get Started

Retrocommissioning takes about three to six months from initial walk-through to final implementation. To begin, contact us, your preferred contractor, or a retrocommissioning agent (RCx). Accompanied by your contractor and an Efficiency Vermont consultant, the RCx agent inspects your facility to find opportunities for savings. The cost of this walk-through (up to $5,000) is 100% covered by us, so it’s easy to get started at little or no expense.

  • 100% coverage up to $5,000 (qualification stage)
  • 50% cost share up to $15,000 (development stage)
  • 10 cents per kWh up to $25,000—based on projected energy savings (implementation stage)

A Five-Step Process

  1. Pre-screening: We assess whether retrocommissioning is cost-effective for your facility.
  2. Qualification (1–2 hours): A RCx agent, your preferred contractor, and our energy consultant inspect your building to identify opportunities for saving.
    [Paid by us: 100% of cost up to $5,000]
  3. Development (1–2 days): RCx agent sets up monitors, performs diagnostics, and develops a report outlining recommendations, including costs to implement and projected savings.
    [Paid by us: 50% of cost up to $15,000]
  4. Implementation: Vendors, RCx agent, and customer carry out work recommended in report, then monitor and optimize.
    [Paid to you: 10 cents per kwh up to $25,000, based on your projected energy savings]
  5. Verification: Our energy consultant measures, documents, and verifies your savings after project completion.
