The 2-hour round trip to the two Warren County Public Schools campuses was a beautiful journey with great learnings in the end. The County is home to a Corvette factory, Fruit of the Loom plant and an international center for refugees, so the district responds to a dynamic demographic that brings 400 new students annually, speaking 40 different languages. Coupled with aging facilities and an engaged community group, the district embraced the challenge to concurrently replace three schools.
The 1936 Richardsville Elementary School was comprised of an instructional facility and a barn that served as the school’s gymnasium. Planning for the next chapter in this school’s history, the stakeholders and design team stayed true to their overriding mission in planning, designing and opening a carbon neutral school. In doing so, they found those objectives also aligned with Energy Star and USGBC LEED® gold protocols. Some of the interesting take-aways:
Defining the Big Decisions
Envelop
Mechanical Systems (geo-thermal)
Kitchen

New District Standards
ICF Structure – time savings during construction, even during in climatic weather, resulted in this becoming the district standard for interior and exterior walls. Shaved a couple of months off of the 15-month typical schedule for this project.
Kitchen & Nutrition Plan – as the largest consumer of energy, the kitchen was evaluated. Working with the nutrition team, deep fried foods were removed from the school’s menu and every 3 weeks the school has a “green lunch” (brown bag with salads).
Metering & Post Occupancy Audits – as with all projects, the occupants’ use of the space and the devices they operate are the unknown factor that can have a major impact on the true outcome of a project. In this case, an unexpected cooler created a spike in energy consumption, as well as higher-than-expected usage in the classrooms. Further evaluation and investigation, the team determined the non-essential cooler was not something they would have at the cost of a 30% increase over the anticipated energy consumption for that space. In the classrooms, they discovered that the personalization of the space with toasters and refrigerators were also impacting energy consumption. The district did not restrict against personalizing their spaces, but did encourage them to cut back on the usage of such items. As more teachers embraced this philosophy, the more were on board with changing their approach to classroom energy use.
Engaging the end-user – students of Richardsville Elementary are more aware of their built environment than one might expect of a student under the age of 11. Part is due to the involvement of the staff and parents, but it was equally interesting to see how the school reinforces that message throughout with super graphics and hands-on learning tools integrated into the interior design.
