Portfolio Energy Performance

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI), and to increase the percent improvement compared to a set baseline. Briggs & Stratton's portfolio comprises 10 facilities including manufacturing, research, testing, warehousing/distribution centers, and corporate offices. Identified energy saving opportunities are shared among the manufacturing facilities and Briggs & Stratton has made substantial use of system assessment and energy Kaizen events to identify energy saving opportunities, with an implementation rate of over 80%.

Energy Performance by Facility

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Briggs and Stratton has achieved energy performance improvement of over 15% at over 50% of its facilities. Introducing a new product may consume more energy for each unit produced at a facility than in the baseline year and may show up as a negative energy intensity. As production stabilizes decreases in energy intensity are expected to resume. In spite of these changes Briggs & Stratton continues to make progress toward the corporate goal of 25% reduction in energy intensity.

Method for Calculating Energy Performance

Briggs & Stratton has a mixture of manufacturing processes including casting, fabrication, machining, assembly operations, and warehousing. Seasonal change in the product mix provides an added challenge to quantifying improvement in energy intensity. Data for production facilities is grouped by manufacturing process to account for varying production levels within the groups. Energy intensity is calculated within each group rather than for individual plants and aggregated for the corporate total. Increasing the use of energy submetering will provide a clearer understanding of facility level energy consumption.
