Sun Microsystems’s Open Work Energy Measurement Project, an internal study comparing the home and office energy use of more than 100 participants in its flexible work program, found that working at home an average of 2.5 days/week saved energy, time and money.
Key findings of the study include:
Employees saved more than $1,700 per year in gasoline and wear and tear on their vehicles by working at home an average of 2.5 days a week.
Office equipment energy consumption rate at a Sun office was two times that of home office equipment energy consumption, from approximately 64 watts per hour at home to 130 watts per hour at a Sun office.
Commuting was more than 98% of each employee’s carbon footprint for work, compared to less than 1.7% of total carbon emissions to power office equipment.
By eliminating commuting just 2.5 days per week, an employee reduces energy used for work by the equivalent of 5,400 Kilowatt hours/year.
Working from home 2.5 days per week saved the employees in the study an average of 2.5 weeks of commute time (8 hours/day, 5 days/week).
Sun’s Open Work platform is an integrated suite of technologies, tools and workplace practices that enable Sun employees to work effectively anywhere, anytime, using any device. Through this program, nearly 19,000 employees around the world work from home or in a flexible office, representing more than 56% of Sun’s employee population.
