Keeping Students Awake ... and More Productive ...

The Washington Post featured a local high school's green renovation in Titans of Ecology, which began

At the brand-new T.C. Williams High in Alexandria, a modern "green" school, students say the environmentally friendly design has led to a serious lifestyle change: They can't doze in class anymore because sunlight pours in from practically every angle.

This points to one of the real benefits of going green, of being environmentally friendly and energy efficient. Yes, there are the direct cost savings in lowered energy use to be gained through going green. At TC Williams the estimate is $100,000 per year in lowered energy costs for T.C. Williams against a total additional cost of $1.2 million for going green (remember, much of that investment was not energy savings related). Okay, about an 8 percent savings per year on the investment. Sounds sort of okay, if not great, right? Stopping there would be a very limited view of the impact of "going green"

What is less often realized is that those energy savings are not even the tip of the iceberg in real benefits, in measurable impact from "going green". Study-after-study of green buildings has found that there is improved worker productivity, reduced absenteeism, and improved retention (reduced turnover) which directly impacts the bottom line (helping companies make green by going Green). In addition, related to these is that workers have fewer health problems -- working in a healthy space turns out to, surprise surprise, contribute to one's health.

But, how to translate this into the school space?

It turns out that there are measures to use ... and by those measures, the benefits of going Green have real meaning. From AIA Architect:

A study in North Carolina revealed that children in schools with more natural day lighting scored 5 percent better on standardized tests than children in normal, comparable buildings.

What is the "value" of that 5 percent test score benefit? How much more would have to be spent on teacher salaries to get that sort of gain? It almost certainly would be far greater than a one-year amortized cost of going Green and increasing natural day lighting.

Thus, the TJ Williams' students likely will not just suffer from not having their daytime naps but also suffer through the problem of having higher test scores (perhaps because they are snoring through fewer classes).

The National Academy of Sciences commissioned a study that indicated that teacher productivity and student learning, as measured by absenteeism, is affected by indoor air quality.

In other words, it isn't just that lighting: the healthier building has a healthy impact on the school environment.

Sadly, the Post article gave voice to shallow-based criticism.

The new three-story T.C. Williams, home to about 2,000 students, cost about $98 million, which is much higher than the price of many regular high schools its size. Alexandria school officials said the facility's green features account for about $1.2 million of its cost. Still, some educators and parents expressed skepticism about the cost of green schools.

John Wilson, a commercial real estate salesman and the father of student J.W. Wilson, said he was surprised that he had not heard much protest about the school's cost. "I am happy that the students have the best of everything," Wilson said, "but I am not convinced that it always translates into a better education."

Well, the "best of everything". Is Wilson focused on and upset about the $98 million? Or, is it the $1.2 million of greening that's got his goat? And well, again that $1.2 million will translate to $100,000 per year in lower energy costs, could reduce other direct costs, (substitute teachers, health care compensation, etc), could lead to improved student health/happiness, and will, almost certainly, translate into improved academic performance of higher value than that $1.2 million each and every year.

All told, for the citizens, that $1.2 million looks like a pretty good investment.
