2015 ASHRAE Community Sustainability Project

The Community Sustainability Project focuses on improving the building efficiency and sustainability for a selected nonprofit organization in order to share the knowledge of members to improve the world around them. The SIUE Student Chapter of ASHRAE has chosen Chappee Cottage on the Beverly Farm Campus in Godfrey, IL. The Beverly Farm Foundation is a loving, caring home for adults with developmental disabilities, providing each individual with physical and emotional security and a dignified quality of life, with opportunities and challenges, within each individual's functional capabilities. Chappee Cottage houses about 25 women and children. Their building currently has an old inefficient multi-zone system with radiant floor heating which has been all but disabled as a result of a grossly inefficient boiler.

The students have been conducting site visits, reading old plans, drawing plans in AutoCAD, developing building energy models through eQUEST and Trane Trace, conducting heating and cooling load calculations for appropriate HVAC system selection for the project.

After the analyses, our students came up with three HVAC options, finished bid drawing, and are currently looking into other ways to save energy via building envelope, windows, lighting, and controls. The most viable option for this project was determined to be a single zone residential split system with a dedicated outdoor air system.  This will allow for energy efficient usage of the equipment while maintaining comfort in the space. The boiler system will be replaced before winter which will allow the radiant floor heating.

Energy analysis of the building was conducted using eQUEST, a public software developed by the Department of Energy. The software helps the students determine how much of an impact the improvements they plan to make will have on the existing building.
