Honda set global goals for the reduction in Co2 emissions from its products and factories in May 2006, including a 10% reduction in Co2 emissions from automobile production from 2001 levels by 2011. for four years, beginning with the fiscal year that ended on March 31, 2005, Honda’s north American factories reduced annual energy use per unit of automobile production by an average 3.2%, going from 7.1 gJ/ auto (6,729 kBtu/auto) in 2005 to a 10-year low of 6.2 gJ/auto (5,877 kBtu/auto) in 2008. However, Honda’s production volumes declined 20% during the following two years as a result of the recession. While reduced production led to a significant decrease in total energy use during the period, the energy intensity of automobile production rose 9.7%. on a global basis average energy use for each automobile produced has been reduced 12.6% over the past five years. Left A Honda associate checks the controls for the air-conditioning units for the Intelligent Paint Booth, which was developed by Honda of America Mfg. in conjunction with the mechanical engineering department at The Ohio State University. The technology was first introduced at the Marysville Auto Plant in 2008 and has been implented at all of Honda’s major automobile operations in North America. Below The paint booth at East Liberty Auto Plant reduces CO2 emissions and energy consumption by using a predictive algorithim to automatically regulate air temperature and humidity. e n e r g y at a g L a n C e energy use intensity/site energy (Per auto Produced) east liberty 5.14 gJ (4,872 kBtu) electricity 1.87 gJ (1,772 kBtu) natural gas 3.27 gJ (3,099 kBtu) marysville 5.29 gJ (5,014 kBtu) electricity 2.03 gJ (1,924 kBtu) natural gas 3.26 gJ (3,089 kBtu) source energy (Per auto Produced) east liberty 9.7 gJ (9,163 kBtu) marysville 10.2 gJ (9,660 kBtu) in auto production plants, all machines and processes must run regardless of the volume of production. So despite its production energy efficiency improvements, lower production volumes ultimately resulted in a lower per-unit efficiency measurement. energy efficiency strategies With a focus on Co2 emissions reductions over the past decade, Honda’s ohio factories have reduced the energy intensity of automobile production by operating equipment with less variability, by ensuring that process energy requirements are met and not exceeded, and by designing equipment that can be easily shut down when not in use. efficient use of Compressed Air. generating compressed air accounts for more than 12% of total electricity consumption, or more than 5% of total energy use. Steps to reduce compressed air generation energy have focused on better management of compressed air systems to provide the right pressure to the right areas at the right times. 72 HigH Performing Buildings Winter 2011
