Resorts and hotels achieving certification under the LEED sustainable building program really do see increased revenue. Actually, these green hotels see a substantial increase in revenue per available room. We shouldn’t forget about the Cornell Center for Hospitality Research study entitled, “The Impact of LEED Certification on Hotel Performance,” by Matthew Walsman, Rohit Verma, and Suresh Muthulingam. Prof. Verma said that certification under the LEED sustainable building program definitely boosts hotel revenue. Their study, as you might recall, compared 93 hotels which earned certification under the LEED sustainable building program to 514 comparable non-certified hotels.
