Without significant changes in the development of Louisville's urban landscape, urban temperatures are expected to increase over the coming decades due to the greenhouse gas effect, the displacement of trees and other natural vegetation, and the expansion of concrete, asphalt and other impervious surfaces. Rising urban temperatures have implications for public health as well as critical infrastructure preservation. 

In an effort to start managing urban heat, Louisville Metro Government is offering two incentives programs for residents and businesses. They include:

  • Cool Roof Rebate Program (residential and commercial)
  • Go Green Loan Program (commercial only)

Learn about Energy Project Assessment District financing for energy efficiency, renewable energy and water conservation projects. (EPAD Program)

Learn about below market-rate financing for small businesses aimed at increasing energy efficiency and creating “green” jobs, products or services.  (Go Green Loan Program)


Cool Roof Rebate Program

The Office of Advanced Planning and Sustainability provides rebates to property owners of $1 per square foot of cool roof installed, with a goal of incentivizing at least 100,000 square feet of cool roofs. Buildings located in Metro Council Districts 1, 3, 4, 5, 6, 12, 14 and 15 are identified as high heat island areas based on the Urban Heat Management Study (2016), and will receive 70% of the available funding for Fiscal Year 2019-20. The program will continue until funds are depleted. Rebates are limited to a maximum of three properties per property owner per fiscal year.
