Energy Efficient Design for Jester Park Nature Center
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 and MidAmerican Energy Company.
On September 27th Polk County Conservation’s Jester Park Nature Center received a 2019 Excellence in Energy Efficient Design Award for achieving 73% kBTU savings when compared to the Commercial New Construction (CNC) program baseline.
A few of the Nature Center’s key features contributing to its energy efficiency:
- An upgraded thermal building envelope that includes:
- SIP roof panels for the roof insulation
- Spray foam in the exterior stud wall framing
- Rigid foam exterior insulation & spray foam in the stud wall furring at the cast-in-place concrete foundation
- A building that benefits from “earth sheltering” with a lower level tucked into the hill side.
- Most of the windows face north, minimizing and managing thermal heat gain from glazing.
- The installation of a geo-thermal heating & cooling system.
- Occupancy sensors for the LED lighting – to reduce the electric consumption.
