Walmart turns green roofs into research labs
Walmart and Oregon's Portland State University are working together on research to advance the use of green roofs. Over the next two years, researchers from the University's Green Building Research Lab will collect data from the largest green roof in Portland, which just happens to be on a Walmart store.
The green roof is being installed in three sections, each designed to test various kinds of green roof design, such as materials and soil depth. The rest of the roof - 52,000 square feet - is a white, cool roof, which will also be monitored to compare how it performs. Sensors will detect surface temperature, water flow and building operations.
Researchers are also collecting data from Walmart's biggest green roof - a 70,000-square-foot "EcoGarden" in Chicago. Comparing the two will result in a comprehensive view of green roof performance in various climate conditions.
