OPN Architects is committed to sustainable design solutions on all our projects. For our K-12 clients, though, we are keenly aware that every dollar saved is money that can be spent in the classroom and invested in student success. That’s why we’re particularly proud two of our projects for the Iowa City Community School District — Penn and Alexander elementary schools — in 2015 were honored with a Excellence in Energy Efficient Design Award at the 2016 American Institute of Architects Iowa regional convention in Des Moines on Sept. 21.
Our work at Penn Elementary — which included the addition of a media center and remodeling — was selected based on 55% energy savings when compared to the baseline for a major addition and renovation. This was accomplished by an efficient ground source heat pump system with VFD units, new ‘Airdale’ exchangers in the existing rooms as well as a heat recovery system; occupancy sensor controls throughout the building and a combination of improved envelope insulation package in the addition and where applicable in the remodeled spaces.
At Alexander Elementary, the building has a 61% energy savings compared to the baseline for new construction. This was accomplished by a combination of highly efficient ground source heat pump system with low air return, transfer air as well as a heat recovery system; dimmable lighting based on daylighting and occupancy sensors and an improved envelope insulation package.
The Excellence in Energy Efficient Design awards program recognizes outstanding efforts in reducing energy use. Award candidates are selected from projects whose designers participated in the Commercial New Construction program offered by Alliant Energy, Black Hills Energy and MidAmerican Energy Company. Projects must have been completed between July 1, 2015, and June 30, 2016. The top 5 projects with the highest kBTU savings percentage in Alliant Energy and MidAmerican Energy’s service territory are selected for an award.
