Sustainability Incentives

March 17, 2017

The Office of Sustainability offers three incentive programs for residents and businesses.  Please take some time to visit the sites below to learn more about these programs.

                -Cool Roof Rebate Program (

Louisville has been identified as having the most rapidly warming urban heat island in the country.  To identify ways to slow the urban heat island, Georgia Tech was contracted to study the drivers of Louisville’s heat island and identify strategies to manage heat.  The recently released Urban Heat Management Study identified cool materials as a key strategy to help mitigate the heat island.  Lighter color roofs reflect sunlight and heat away from a building, reducing roof temperatures. White commercial roofs and cool residential roofs absorb less heat and stay up to 50–60°F cooler than conventional materials during peak summer weather.


The Louisville Metro Office of Sustainability’s Cool Roof Rebate Program will provide 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. This program supports the city’s efforts to reduce the heat island and will help citizens reduce energy use at the same time. 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 at least 60% of the available funding. Applications will be accepted beginning on March 1, 2017, and the program will continue until funds are depleted.


                -2017 Enhancements to the Green Infrastructure Incentive Program (

The Louisville Metro Office of Sustainability is pleased to announce enhancements of its Green Infrastructure Incentive Program. The incentive funds are used to match MSD’s Green Infrastructure Financing Incentive program, such that eligible projects that are approved by MSD could qualify for additional incentives through the Office of Sustainability. Eligible projects include green infrastructure installations that keep at least 1” of stormwater out of the sewer and drainage system such as rain gardens, pervious pavement, green roofs, infiltration drains and water harvesting systems.


                -Free technical assistance and verification for Energy Star Certification (

The Louisville Metro Office of Sustainability and the Louisville Energy Alliance have a goal of moving Louisville into the top 20 cities in the US with the most number of Energy Star Certified buildings.  Buildings will need to track their energy usage through EPA’s Portfolio Manager program.  Once a building receives a score of 75 or greater, a free verification will be performed.  If a building is struggling to reach the score of 75 or greater or would like to learn ways they can increase their energy efficiency and save money, Kentucky Pollution Prevention Center, a non-regulatory and confidential center will offer free technical assistance.      


                -Free Portfolio Manager Training (

The Louisville Energy Alliance, in partnership with Louisville Metro Government’s Office of Sustainability, will host a FREE EPA ENERGY STAR Portfolio Manager training session on March 28, 2017 from 1-3pm. 
The training will include a one-hour webinar hosted by EPA ENERGY STAR followed by on-site assistance with creating Portfolio Manager accounts and entering data into the software. Attendees will learn the basic functionality of Portfolio Manager as well as how to log energy and water use data and generate custom reports using the data. By the end of the session, attendees will have entered one year of energy data, have a basic understanding of the capabilities of Portfolio Manager and be one step closer to ENERGY STAR certification.
