ATSR guided Chippewa Falls Area Unified School District in long-term planning to meet the District’s needs. The master plan includes:
- Enrollment capacity analysis/forecast
- Comprehensive 25-year facilities timelines
- Major capital improvements per building
- Facility age/useful life breakouts per building
- Property acquisition options
ATSR designed this high-performance new elementary school for Chippewa Falls Area Unified School District.
The unique design celebrates ‘future-ready,’ student-centered learning with ubiquitous technology throughout. ‘Break-out’ spaces are designed as centers for project-based and collaborative learning in the classroom clusters.
Partnering with state government energy programs, ATSR designed/engineered/implemented energy-efficiency and sustainability features for a 10-year payback, giving the District $300,000 in energy savings through the following highlights:
Site Features
- Limited paved/impervious surface is on the site
- Drinking water is infiltrated on-site; no wastewater leaves the site
- Amount of imported fill is limited for the site
- Site infiltrates water to site from other sites
- Bio-retention/infiltration basins are incorporated
- Bike racks are convenient for students and staff
- Pathways provide access for users to grounds
Architectural Systems
- High-performance windows with solar glazing & argon gas in thermo-break frames for comfort
- Sun shading screens at south-facing windows to reduce undesirable glare and heat gain
- Roof insulation is 6 inches for thermal integrity
- Local materials/labor reduces transport costs
- Building oriented for day-light & energy efficiency
- Visual connection to nature via design fenestration
- Design exceeds energy code to meet 2030 goal
- Acoustical materials above 20’ height sound
Electrical Systems
- Automatic dimming day-light harvesting controls
- Occupancy sensor controls throughout
- Lighting power reduced by 30% with LED lighting
Mechanical Systems
- Total heat recovery on 90% of classroom exhaust air – Variable-Air-Volume with gas boiler and air cooled chiller for commons, gym, offices, and classrooms
- Variable frequency drives (VFDs) on building heating water loop pump motors for hydronic system coils
- VFDs on chilled water loop pump motors
- VFDs on chiller compressor to improve load curve – 10% improved chiller efficiency values to 1.07kW/ton
- Efficiency condensing gas boiler with aggressive temperature resets with return water temperatures
- 95% efficient natural gas service water heating
- Reduced fan power for supply/return/exhaust
- Demand control ventilation (i.e., CO2 sensors, control of zones) to reduce outside air while occupied
- Occupancy sensor control of zone temperature
- Displaced air at floor / return above occupied area
