Advantages of Green Design

BENEFITS OF GREEN BUILDING: PRODUCTIVITY

• A study by Carnegie Mellon University measuring the relationship between increased lighting control and productivity showed an average increase of 7.1% in productivity.
• Average employee relocation within a building averages 25% annually for most commercial spaces at a cost of about $2,500 each. Flexible design features often found in integrated green buildings can help cut employee relocation costs by 90%.
• Average annualized costs for personnel amount to $200 per square foot, compared to $20 for bricks and mortar costs and $2 for energy costs.

BENEFITS OF GREEN BUILDING: HEALTH

• People in the U.S. spend about 90% of their time indoors.
• EPA studies indicate indoor levels of pollutants may be two to five times higher, and occasionally more than 100 times higher, than outdoor levels.
• An investigation of 20 studies with 30,000 subjects found significant associations between low ventilation levels and higher carbon dioxide concentrations - a common symptom in facilities with sick building syndrome.
