Recent studies have given us a good context within which to examine energy efficiency opportunities within the non-refrigerated warehouse population, better known as cold storage facilities. Utility costs for these facilities can run from 8.7% to 17.3% of revenues, second only to labour costs, with an average of over 11% based on studies, with an average energy consumption of 1.54 kWh/cubic foot. It has been suggested that energy consumption in an energy-efficient cold storage facility should be as low as 0.6 kWh/cubic foot. Electricity costs are typically 70% of the total energy bill. One other study found that the annual energy intensity of cold storage facilities was some 101,000 BTU/sq foot, almost three times that for non-refrigerated warehouses.
Star Energy is dedicated to helping cold storage facility owners increase productivity and profits while reducing their energy consumption. Our comprehensive energy audits examine all aspects of a cold storage facility’s energy consumption. We examine utility bills, inspect HVAC equipment, review maintenance procedures and systems, and analyze building envelopes to accurately gauge your overall energy consumption and measure the environmental impact of your operation.
Armed with this information, we work with cold storage facility owners to develop clear-cut, actionable energy and maintenance strategies. We not only identify various energy conservation measures but also provide owners with tools such as project financing, implementation management, and incentive management to assist them in implementing various identified energy conservation opportunities.
Solutions for increasing the energy efficiency of your operation include utilizing new technologies; replacing outdated and oversized equipment with properly-sized, high efficiency models; utilizing alternative fuel sources and developing no-cost and low-cost strategies to reduce the amount of energy you use, lower your carbon footprint and boost profits.
It can't be overstated that increasing the energy efficiency of you operation is the most effective way to reduce your overall operating costs. Retrofitting older equipment with new, energy- saving technologies is a cost-effective way to save money. Examples of areas in which we have seen substantial energy savings include reduction of humidity loads, improving evaporator performance and re-piping in certain circumstances. In addition to providing sustainable and practical solutions for increasing energy efficiency, Star Energy also provides training and tools for the ongoing monitoring and evaluation of energy use, which alone can reduce your overall energy costs by up to 15 percent.
