“Some areas of central Canada, such as  
Manitoba, are almost all renovation because  
Canada’s primary power source is providing  
rebates to upgrade glazing and windows,  
focusing on schools. In general, the Midwest  
is seeing about 75 percent new construction  
versus 25 percent renovation.”  
Scott Bucher,a project  
manager with Bucher  
Glass in Fairbanks,  
Alaska, says his firm’s  
work is split around 80-  
percent new/20-percent  
In the Northwest, our rough estimate is  
that renovation work is probably less than 10  
percent. We see the renovation opportunity  
increasing in the next three to five years, but  
doubt we’ll reach percentages common in  
the east and northeast because this building  
stock is not as old. There are a number of  
significant renovation projects being explored  
now in Portland, Seattle and Vancouver. All  
are being driven by new construction that has  
surrounded the existing buildings. As new  
buildings open, it puts pressure on owners to  
upgrade their existing facilities to compete in  
the lease/rent market.”

“In the Middle Atlantic and Northeast,  
we would estimate about 20 percent  
renovation versus 80 percent new  
construction. In the Deep South and  
Southeast, we would expect renovations  
to be lower due to fewer opportunities.”
