Lehigh Hanson Facilities Join Energy Star Challenge
Eleven of Lehigh Hanson Inc.’s aggregates production facilities across the country are participating in the EPA’s Energy Star Challenge.
The 11 facilities spread between Texas, Illinois, Indiana, Pennsylvania and California have agreed, under the terms of the challenge, to improve energy efficiency by at least 10 percent.
The plants will use various strategies to meet the efficiency goal. These include shifting production schedules to reduce electrical usage during peak-demand times where possible, and participating in electrical energy curtailment programs. Other initiatives will include the use of cleaner, more efficient diesel engines to lower fuel consumption and emissions, and regular maintenance of equipment, a Lehigh representative told Environmental Leader.
The wider challenge aims to achieve the 10 percent efficiency improvement for the more than 5 million commercial and industrial buildings in the United States. The EPA estimates that commercial buildings and industrial facilities contribute approximately 45 percent of US greenhouse gas emissions.
The EPA says that if the energy efficiency of commercial and industrial buildings in the US improved 10 percent, Americans would reduce greenhouse gas emissions equal to those from about 30 million vehicles, while saving about $20 billion on annual utility bills.
In July, eight Toyota manufacturing sites in North American announced that they had reduced their energy intensity by 10 percent or more, meeting the standards of the Energy Star Challenge for Industry. Collectively, these eight sites have reduced energy intensity by nearly 24 percent from their baseline; however, Toyota didn’t state the start or end year for these percentages.
