Kilowatt Crackdown Challenge

In November of 2007, the EPA’s ENERGY STAR program adopted Louisville as a new model partner – one of only a few in the country.  That specialized partnership has launched an aggressive effort to make Metro Government facilities more energy efficient.  In this time of tight budgets and rising energy prices, conserving energy makes sense – and saves money.  Part of Mayor Jerry Abramson’s latest budget outlines plans to reduce energy consumption in city buildings by 10 percent. 

Energy efficiency is a major building block of our new “Go Green Louisville!” initiative.  Commercial buildings use $200 billion worth of electricity and natural gas annually and are responsible for nearly 50 percent of our national emissions of greenhouse gases.

Six commercial real estate associations – BOMA, IFMA, CCIM, IREM, ICSC and CREW – have partnered with Metro Government to create the Louisville Energy Alliance (LEA),  a group that can make powerful strides toward energy efficiency in our community. 

On July 1, the Louisville Energy Alliance kicked off the Louisville Kilowatt Crackdown Challenge, a 16-month competition to promote energy efficiency in commercial buildings.  LEA and ENERGY STAR will provide all the necessary tools and training – free of charge – so building managers may properly assess their buildings’ energy usage and determine ways to make improvements.  The highest-performing buildings will be publicly recognized and will receive awards for their work.

Energy conservation can begin with changes as simple as turning up the thermostat in the summer and turning off lights and computers at the end of the workday.  Improvements to infrastructure – such as new HVAC systems or new windows – can have a more drastic effect on energy use.

Green Roof Concept
Metro Development Center
444 S. 5th Street

Louisville Metro’s first green roof is being constructed atop the Metro Development Center (MDC), 444 S. 5th St., which serves as a one-stop shop for Louisville’s developers, builders and contractors. The six-story building was originally built in the early 1900's as a parking garage, and it was converted it to an office building in the 1980's.

In addition to its central downtown location, MDC was chosen to receive the first green roof for a very basic reason – the roof needed repairs! It was also determined to have a suitable load-bearing structure. About 11,000 square feet will be available for planting, excluding a 1,200-square-foot “penthouse”, which houses various mechanical systems. Although the penthouse roof will not be planted, it will receive a special Energy Star-certified coating.

The firm of Luckett & Farley was chosen to design and oversee the green roof project.

An “extensive” style roof was dictated by the roof structure analysis, which established limits for the weight of the green roof materials.

To keep the roof as maintenance-free as possible, native plants will be widely used, including a variety of drought-resistant sedums. Planters with small trees will be located over structural support columns. Metro Landscape personnel will provide periodic seasonal maintenance. An irrigation system is being installed as part of the roof.

The new green roof will provide many environmental benefits. It will provide insulation value, and the energy value will be tracked through Portfolio Manager monitoring software. Storm water run-off is expected to be reduced by up to 50%. The roof will contribute to urban heat island mitigation, improved air quality, and added habitat for insects and birds. Last but not least, the green roof will provide a model to remind the community to Go Green, Louisville!
