Overview

Building performance optimization, also known as recommissioning or retro commissioning, is a systematic process used to evaluate, test, and fine-tune HVAC control systems to ensure they are operating as intended. At JRE Controls, this includes detailed data analysis, on-site inspections, and system audits, followed by targeted software optimization, hardware upgrades, and control adjustments. Industry best practices recommend recommissioning every 3–5 years to restore system performance.  

Purpose

Over time, HVAC systems drift from their original design due to changes in building use, equipment wear, and control overrides. Without regular recommissioning, this drift leads to wasted energy, higher operating costs, comfort complaints, and unnecessary strain on equipment. Recommissioning helps identify hidden inefficiencies, ensures systems operate reliably, and supports long-term cost control and sustainability goals. 

Typical Benefits for Buildings

• Reduced energy consumption and utility costs

• Improved occupant comfort and temperature consistency

• Extended equipment life and reduced maintenance issues

• Lower operating and lifecycle costs

• Improved system reliability and performance visibility

• Reduced environmental impact and improved sustainability metrics
