A new Guilford County middle school is getting a lot of publicity because it’s been designed to be more environmentally sensitive than most schools. Here’s what the Raleigh News & Observer wrote about it.
How does it compare to what’s being built by Charlotte-Mecklenburg Schools? Well for starters, though the article says the new Northern Guilford Middle school was built for only a half a percent more in construction costs, for $26.5 million, CMS’ middle schools are being built more cheaply, especially if you consider cost per student.
I phoned Tony Ansaldo, CMS director of architecture, to get some facts. Ansaldo said Crestdale and Bradley, two of CMS’s newer baseline (that is, typical) middle schools, cost approximately the same in today’s dollars as the Guilford middle school but are designed for 1,200 students instead of 950 at the Guilford school. He says the next CMS middle schools to be built will likely be 130,000 square feet for 1,200 students, down from 145,000 square feet at Crestdale and Bradley. The Guilford school is 140,000 square feet.
Ansaldo applauds Guilford for working to build a greener school. He also talked about what CMS is doing to help make new schools greener. (One irony, he noted, is that older schools from the 1930s to 1950s have much better daylighting than the 1960s and 1970s schools.) Among other things, CMS tries to design window walls to take advantage of daylight, though most CMS schools are not being designed specifically as “daylit” schools, he said. (One exception is the new Mint Hill Middle School, where a UNC Charlotte daylighting expert was a consultant.) People using the school love it, he said, though the higher windows are harder for maintenance crews to clean.
Ansaldo also said CMS had looked at the dimming system for fluorescent lights, mentioned in the article, but at the time it wouldn’t have paid for itself over the school’s lifetime. Technology is changing quickly, he noted, so maybe newer systems are more economical.
With those advances it’s possible that soon the cost of building a green school will be cheaper than a conventional building, even before lifetime energy costs are considered.
There’s a cohort of people in Charlotte-Mecklenburg who really want CMS to build the cheapest schools possible. They make a lot of noise, and many are not conversant with green building, either the concept or the details.
Another cohort wants CMS to build much greener schools. They don’t make nearly as much noise, at least not in political circles. And they don’t seem to recognize the political power the “cheap” cohort exerts.
So the current push for school buildings is for cheap, not green.
