Retro-Commissioning

Retro-Commissioning (RCx) is the process of monitoring, troubleshooting and adjusting electrical, mechanical and control systems in existing buildings.

Improve the Performance of Your Building

Your building may have met the energy codes when it was originally designed, but do you know how well it is performing now?

The PNM Retro-Commissioning (RCx) Program gives PNM customers the opportunity to get information from experts on how to improve the system efficiency of commercial buildings. Study incentives help pay for the building assessment, and savings incentives help reduce the cost of implementing the assessment findings.

RCx Tier 1

Focus on Common Measures

Medium-sized buildings can benefit from a standard RCx assessment that focuses on common system efficiency improvements.

Study Incentive

RCx Tier 1 study incentives are available for all projects that meet the minimum eligibility criteria (see Customer Eligibility below). The study incentive is paid directly to the contractor (Trade Ally) to help buy down the cost of the study, based on annual energy usage as follows:

 
Building Annual kWh Usage Study Incentive
<750,000 $1,500
750,000-1,000,000 $2,000
1,000,000-2,000,000 $2,500
2,000,000-3,000,000 $3,000
3,000,000+ $3,500

RCx Tier 2

Building Optimization for Greater Savings

Larger buildings may have opportunities for a more complex RCx assessment to yield even greater savings.

Study Incentive

A RCx Tier 2 study incentive of $10,000 is available to building owners whose facilities meet the minimum eligibility criteria (see Customer Eligibility below). The study incentive is paid directly to the Trade Ally to help buy down the cost of the study. Trade Allies receive 50% of the incentive after the study is conducted and a master list of findings is reported, on the condition that the customer agrees to implement all no-cost and low-cost measures. The remaining 50% of the study incentive is paid upon receipt, review, inspection and payment of the final project application.

RCx Tier 1 and Tier 2 Savings Rebates

The PNM RCx program offers rebates for implementing the low-cost operational and maintenance improvements from a Tier 1 or Tier 2 study. Click here to access the writable PDF incentive applications.

RCx Tier 1 and RCx Tier 2 energy savings are paid at $0.075 per kWh of one year of projected, annualized savings.

The savings rebate is based on meeting the eligibility requirements and hiring a qualified RCx trade ally.

Customer Eligibility

RCx Tier 1 Eligibility
To be eligible, all of the following criteria must be met:

1) Applicant must provide PNM Program team with an Energy Star Portfolio Manager benchmarking report;

2) Building must meet at least one of the following size criteria:

  • Be at least 50,000 ft2 in size, OR
  • Use at least 750,000 annual kWh, OR
  • Use at least 500 kW annual peak demand;

3) Customer must commit to installing all identified no-cost and low-cost measures, defined as those measures with payback of less than two years and less than $2,000.

RCx Tier 2 pre-application
To be eligible, all of the following criteria must be met:

1) Building must have direct digital controls (DDC) in place connected to a building management system (BMS);

2) Customer must commit to installing all identified no-cost and low-cost measures, defined as those measures with payback of less than two years and less than $5,000;

3) Building must meet at least one of the following size criteria:

  • Be at least 100,000 ft2 in size, OR
  • Use at least 1,500,000 annual kWh, OR
  • Use at least 1,000 kW annual peak demand;

4a) Customer must have participated in required RCx Tier 1 identified improvements, OR

4b) Applicant must provide PNM program team with an Energy Star Portfolio Manager benchmarking report

AND

4c) Applicant must show a minimum 5% energy savings opportunity through a documented study, most likely conducted by the firm representing the customer.

(The 4b plus 4c option allows for eligible Tier 2 buildings undergoing a more thorough RCx process or a performance contracting process to consolidate assessments into one project.)

Low-Cost or No-Cost Improvements

The following are examples of the PNM RCx upgrades Tier 1 program, and are typically low- or no-cost energy efficiency measures:

1) Re-set

  • Duct Static Pressure (DSP)
  • Supply Air Temperature (SAT)
  • Chilled Water Supply Temperature (CHWST)
