Located in Iowa City, IA, the Federal Building & U.S. Post Office is a 3-floor, multi-purpose facility. Its primary tenants are the U.S. Postal Service, U.S. Geological Survey, and Veterans Health Administration.


U.S. General Services Administration staff members at the Iowa City Federal Building are focused on energy conservation. Improved energy efficiency and reduced energy usage is a continuous process for the facility.


GSA worked with electricity provider MidAmerican Energy Company and engineering consultant Nexant to create an energy efficiency action plan in 2009. The plan identifies several opportunities for energy savings at the Iowa City Federal Building.


GSA upgraded lighting components at the facility to energy-efficient T-8 tubes and ballasts. The agency also replaced and reduced the number of second-floor corridor ceiling fixtures and added timers and sensors to outdoor lighting.


Iowa City Federal Building management and staff continually monitor boiler and chiller startup and shutdown timing. GSA also monitors building temperatures daily and makes adjustments when necessary. Air handling unit schedules are adjusted meticulously to avoid wasteful conditioning in unoccupied spaces.


Equipment upgrades and GSA's pro-active approach to monitoring building equipment and conditions increased tenant comfort and decreased overall energy usage by 18.4 percent from 2003 baseline figures.


As for the future of energy efficiency at the Iowa City Federal Building & U.S. Post Office, GSA will replace the building's 37-year-old low pressure steam boilers with new hot water boilers. New piping, controls, and air handling unit hot water coils will also be installed. The agency plans to replace leaking entry doors and install an advanced metering system to track facility energy usage.


Other proposed upgrades include new air handling unit variable frequency drive (VFD) controls, supply and return air motors, chiller controls, and second-floor windows. 


The Iowa City Federal Building & U.S. Post Office is in the midst of a retro-commissioning study to ensure that proposed energy upgrades will reduce operation and maintenance costs. The study may identify additional opportunities to reduce energy demand.

These and other energy improvements are expected to receive approximately $642,000 in American Recovery and Reinvestment Act (ARRA) funding. GSA is committed to meeting its energy goals and continually reducing energy consumption at the Iowa City Federal Building and U.S. Post Office.


GSA sent letters to tenants outlining energy goals as prescribed by an Executive Order designed to strengthen the environmental, energy, and transportation management of federal agencies. GSA also uses tenant board meetings to inform agencies about energy-saving initiatives and encourage energy efficiency.
