The Federal Energy Management Program (FEMP) provides acquisition guidance for commercial steam cookers, a product category covered by ENERGY STAR efficiency requirements. Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified products or FEMP-designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.
FEMP's acquisition guidance and associated ENERGY STAR efficiency requirements apply to pressurized and atmospheric (pressureless) commercial steam cookers (also known as steamers). Steam tables and kettle steamers are excluded.
In the federal sector, commercial steam cookers are typically used in commercial food service operations like cafeterias in General Services Administration (GSA) buildings and dining halls on military bases.
This acquisition guidance was updated in December 2015.
Find Product Efficiency Requirements
The U.S. Environmental Protection Agency (EPA) provides commercial steam cooker efficiency levels and product specification information on its ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. Get a list of ENERGY STAR-qualified steam cookers.
Make a Cost-Effective Purchase: Save More than $700 by Buying ENERGY STAR
FEMP has calculated that the required ENERGY STAR-qualified steam cooker saves money if priced no more than $719 above the less efficient model. The best available model saves up to $2,898. Table 1 compares three types of product purchases and calculates the lifetime cost savings of purchasing efficient models. Federal purchasers can assume products that meet ENERGY STAR efficiency requirements are life cycle cost-effective.
|Table 1. Lifetime Savings for Efficient Commercial Steam Cooker Models|
|Performance||Best Available||ENERGY STAR||Less Efficient|
|Cooking Energy Efficiency||74%||50%||30%|
|Idle Energy Rate||260 W||400 W||600 W|
|Annual Energy Use||987 kWh||3,080 kWh||4,060 kWh|
|Annual Energy Cost||$89||$277||$365|
|Lifetime Energy Cost (12 years)||$931||$3,110||$3,829|
|Lifetime Energy Cost Savings||$2,898||$719||======|
Cooking Energy Efficiency: Represents the amount of energy absorbed by the food compared to the total energy used by the appliance during the cooking process.
Idle Energy Rate: A measure of appliance energy consumption while holding or maintaining a stabilized operating condition or temperature.
Annual Energy Use: Includes preheat, active, and idle energy used to cook 50 pounds of food per day. Assumes a three-pan, pressureless steam cooker used an average of 4 hours per day, 250 days per year.
Annual Energy Cost: Calculated based on an assumed electricity price of $0.09/kWh, which is the average electricity price at federal facilities throughout the United States.
Lifetime Energy Cost: The sum of the discounted value of annual energy cost and an assumed product life of 12 years. Future electricity price trends and a 3% discount rate are from Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis - 2015: Annual Supplement to NIST Handbook 135 and NBS Special Publication 709 (NISTIR 85-3273-30).
Lifetime Energy Cost Savings: The difference between the lifetime energy cost of the less efficient model and the lifetime energy cost of the ENERGY STAR model or best available model.
Best Available Model Column
Calculated based on the ENERGY STAR List of Qualified Products. More efficient models may be introduced to the market after FEMP's acquisition guidance is posted.
ENERGY STAR Model Column
Calculated based on current ENERGY STAR efficiency levels. Federal agencies must purchase products that meet or exceed ENERGY STAR efficiency levels.
Less Efficient Model Column
Calculated based on typical products used in commercial kitchens.
