In the past 10 years, green roofs in Portland have come a long way. Jason King, a landscape architect with GreenWorks PC, said constant sharing among those in the design community helps him and others learn from mistakes and advance green roof designs.
“It’s amazing to see how much better they’ve gotten and more refined they are,” said King. “The mistakes aren’t really mistakes. They’re just ways of experimenting and being able to improve. Everybody is willing to share information.”
King said green roofs can satisfy a number of requirements: they can be low-maintenance ways of providing insulation, they can manage storm water and they can be a “beautiful amenity.”
In addition to meeting sustainability goals, green roofs, also called ecoroofs or living roofs, can be convenient homes for birds and butterflies.
GreenWorks has designed a terrace and ecoroof for the First and Main building, which is under construction in downtown Portland and developed by Shorenstein Properties. The ecoroof could include photovoltaic panels, which King said would help the building achieve LEED platinum certification. [Read full article]
