Frank Carlson Federal Building and Courthouse
The General Services Administration's (GSA) Frank Carlson Federal Building and Courthouse in Topeka, Kansas, has six stories–four above grade and two below grade–and a large central atrium.
Energy-efficiency and energy-reduction measures were accomplished at the Carlson Building as the result of a full building retro-commissioning study. The findings provided direction for an energy-reduction renovation project that included the following improvements:
- Installation of four high-efficiency, climate-changer air handlers
- Replacement of Moduline® terminal units with variable air volume boxes
- Commissioning of new equipment
- Advanced metering of all energy and water sources
- Replacement of rooftop solar panels used for pre-heating domestic water.
From fiscal year (FY) 2008 to FY 2011, the Frank Carlson Building reduced overall energy usage by 6.5%. During this period, utility costs escalated more than 29%, so the 6.5% reduction in energy use provided an avoided utility cost of approximately $17,500 per year.
For the FY 2012 period ending February, compared to the same period of FY 2011, the Frank Carlson Building saw an energy reduction of more than 10.5% and a utility cost avoidance of approximately $13,800 for the current fiscal year period compared to the same period in 2011.
The building also received several awards for its energy reduction efforts, including the ENERGY STAR® Building Label in 2009 and 2010. In 2011, the Frank Building was certified as being in compliance with the "Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings."
