The “hidden waste” uncovered during audits—your workshop may have it too.

Photovoltaic glass is a typical example of… High-energy-consuming industries — Mixing, melting, annealing, tempering, and coating: each process is a major energy consumer. During the recertification audit of its energy management system, a certain photovoltaic glass company underwent…

A transformation from “non‑compliance” to “real, tangible benefits.” The audit was conducted by the professional audit team of United Zhiye Certification Co., Ltd.

01 Two non-compliances have opened a loophole in management.

On-site audits identified two issues: First, for key production equipment such as the mixing machine, melting furnace, annealing furnace, tempering furnace, air compressor, and coating machine, no documentation could be produced. Hourly production data ; Second, the “Equipment Failure Statistics” show that the equipment has a high operating rate, Frequent breakdowns and shutdowns 。

This constitutes a reference to GB/T 23331-2020 / ISO 50001:2018, “Energy Management Systems — Requirements and Guidance for Use.” Clause 9.1.1 The nonconformity—monitoring, measurement, analysis, and evaluation of energy performance—lacks a key characteristic. The enterprise had previously assumed that “a high equipment utilization rate means good operation,” whereas… High-frequency fault-induced shutdown , quietly eating away at energy efficiency.

02 From “Non-compliance” to “Consensus”  

The audit team promptly convened a roundtable discussion with the Production Department, the Mechanical and Electrical Department, and management to thoroughly explain and align with the requirements of clause 9.1.1. Hourly production data The significance of energy performance evaluation; an analysis of the energy‑cost implications of frequent breakdown‑related shutdowns, helping enterprises break free from the inertia of prioritizing output over energy efficiency. As a result, companies proactively acknowledge their three major weaknesses— Data management is lacking. 、 Fault management is inadequate. 、 Energy efficiency and fault data are not synchronized. , and establish Special Rectification Task Force 。

03 Three months, one closed-loop rectification system

Based on this, the company has implemented three initiatives:

· Formulate “Daily Production Output Data Management System” , standardize data collection, recording, and evaluation.

· Formulate Management System for Analyzing Production Equipment Failures , clearly define fault classification and grading, as well as the response mechanism.

· Establishing the relationship among production output, equipment failures, and energy consumption Data Integration and Analytics Platform , Conduct a special optimization initiative for equipment energy efficiency

04 Results: Numbers Don’t Lie

The value of auditing extends far beyond a mere certificate. By applying standardized metrics, we transform invisible losses into… Visible Data ——This is precisely Energy Management System Certification The significance of.
