Green buildings, growing assets
A major collaboration into the study of building value by building green
GREEN VALUE HAS
SHOWN THAT THERE IS VALUE
IN BUILDING GREEN.
GREEN VALUE EXAMPLES
Rick Nevin and Gregory Watson found that people pay $10-$20 more for a home for every
$1 reduction in annual fuel bills.
The Heschong Mahone Group found that ‘adding skylighting to the average non-skylit retail store
would be likely to improve its performance by 40%’.
Pennsylvania Power and Light noted a conversion's electricity savings amounted to a payback in
4.1 years with a 24% return on investment. However benefits from lower absenteeism and higher
productivity meant a simple payback of just 69 days, a 540% return on investment.
At Wal-Mart’s Lawrence, Kansas, ‘Eco-Mart’ skylights were installed to reduce lighting costs.
Employees asked to be moved to the daylit part because sales were higher there.
Reno Post Office was renovated. The improved productivity gains paid for the entire
renovation of $500,000 in less than a year. The annual savings in energy use and maintenance
were a 'free bonus'.
Hyde Tools found that new lighting enabled workers to improve quality control by the equivalent
of $25,000 a year. Every dollar saved was thus worth $10 in improved sales: the retrofit was worth
$250,000 extra sales annually.
CABE's The Value of Good Design quotes a 21% improvement in hospital discharge rate from
a hospital renovation, effectively reducing total costs by 21%. It improved care quality, speed,
satisfaction and had spin-off benefits of lower drug use, reduced return visits and other factors.
