Tips To Reduce Energy Costs In A Refrigerated Warehouse.
Updated: Mar 27, 2020
For cold storage facilities the second highest operating cost is energy. Maintaining stable temperatures, especially in frozen food applications, requires continuous refrigeration and massive amounts of energy. Finding ways to balance energy costs and temperature stability is a constant battle forcing operators to perpetually seek new technologies and strategies that protect product and their bottom line.
Below are six strategies that can lower energy costs while maintaining stable temperatures inside frozen food warehouses.
Conduct energy audits to identify energy wastes: The first thing facility management experts do is the facility energy audit. They assess how much energy your facility is consuming and evaluate the measures to improve the efficiency of your facility. They conduct energy audits at different levels. Basically there are three levels of energy audit – level zero, level one and level two.
These experts identify the level that best suits the needs of the client. Level zero is for facilities which require quick and brief screening. Level one measures buildings energy cost by brief on site survey, through which it provides saving and cost analysis of low/no cost measures. Level two will receive a more detailed survey and energy analysis, which will suggest practical measures to change operational and maintenance procedures that can conserve more energy. Not only once, they regularly conduct energy audits to identify the energy wastes.
Make use of renewable energy sources: Facility managers know that audits alone cannot conserve energy. They properly plan and integrate renewable energy systems to improve the energy performance of the facility. Some of the renewable sources they generally use include solar electric systems, wind turbine systems, and geo thermal systems. They make extensive modifications to these systems before connecting them to the utility grid.
They also provide periodic maintenance for the long run and high performance of these systems.
Use energy efficient lighting: Experts from reputed facility management firms have many options to conserve energy by using effective lighting techniques. Using latest lighting technology, they can cut lighting energy costs significantly. They try to choose energy efficient retrofits that increase the quality of lighting. High efficiency replacements for incandescent lamps, lamps with electronic ballasts are widely used for upgrading the lighting system. They also increase the energy efficiency by taking advantage of the “Daylighting” – the use of natural sunlight to brighten up and/or warm a facility’s interior.
Use zoned HVAC systems: Most successful energy management programs are focused on the proper usage of zoned HVAC systems. New technologies allow facility managers to opt HVAC systems to reduce energy usage by 25-50 percent .
Install programmable thermostats: With a goal to save more energy and money, facility managers install programmable thermostats, which offer the flexibility to manually override a given program for both shorter and longer periods.
