From private residences to cultural institutions, “green” roofs are cropping up on more buildings — including the Whatcom Museum’s Lightcatcher Building in downtown Bellingham.
Olson Kundig architects constructed the Lightcatcher Building in 2009. The roof consists of layers of soil, a root barrier, a drainage system and a water-proofing membrane.
Anyone can observe this architectural feature, which provides many ecological benefits. It was designed to conserve energy, absorb rainwater (to prevent stormwater), filter the air and serve as a habitat for wildlife.
Green roofs can also remove heat from the air through a process called evapotranspiration.
Bellingham Public Works staff regularly maintain the area, said Stefanie Cilinceon, communications and outreach coordinator, in an email. In July, public works added new soil and native succulents, such as Oregon and broadleaf stonecrop.
“The green roof on the museum is a demonstration project that is intended to build public awareness,” Cilinceon said, focusing attention on water conservation.
On Sept. 19, the museum will host a tour during Whatcom Water Week, an annual community event highlighting the county’s water resources. It’s located at 250 Flora St. in Bellingham.
