Arizona State University: Student Pavilion
Background
Arizona State University’s (ASU) Student Pavilion is located at the center of student activity. Designed as a student-centric facility, students manage and operate the pavilion with oversight from Memorial Union resident staff. The building hub provides opportunities for entertainment acts, guest lecturers, and student productions. The event space seats 1,200 and features movable partitions to allow subdivision of the space into three separate rooms. The second floor houses office space for student government and organizations. Classrooms and other academic functions are located on the third floor.
Due to the location and student-centric focus, the Student Pavilion was selected to become the first Net Zero Energy building at ASU. The pavilion provides an opportunity to demonstrate and teach Net Zero Energy and Zero Waste practices. ASU has committed to achieving Zero Waste by 2025. Post-occupancy commissioning will address building systems refinement and identify lessons learned for future NZE and ZW projects at ASU.
Solutions
The following energy conservation measures were implemented at the Student Pavilion:
ECM | Details |
|---|---|
| Planned Solar PV | - 200 kW roof mount array |
| Systems & Process Load Metering | - Plug-load control system provided throughout open and private office areas - Tiered metering system allows for areas and components to be zeroed-in for assessment and refinement |
| Energy-efficient office, classroom, kitchen equipment | - All university-purchased equipment is vetted for energy consumption and must meet ENERGY STAR certification, when applicable - Equipment integrated into energy modeling to assess performance and effect on overall energy goals |
| Exterior shading of windows and walls | - Exterior terrace element allows for primary expanses of glazing on the south elevation to be shaded through louvers and a future overhead photovoltaic canopy - Minimal glazing positioned in high or direct exposure locations - South-facing glazing recessed and screened - West-facing glazing provided with static louver system and dynamic glazing to lessen the effect of any direct exposure and limit heat gain within main lobby |
| High levels of building envelope insulation | - Continuous fully-sealed weather barrier - 4-inch-deep corrugated metal skin with perforated cap flashing allows heat to funnel up and escape - High-efficiency building envelope includes spray insulation at stud cavity and mineral wool insulation on exterior side of sheathing |
| High-efficiency HVAC, including chilled beams and evaporative cooling | - Chilled beams in all open and private offices, classrooms, and tutoring spaces - Indirect evaporative cooling units paired with air-handling units provide efficiency and assist with cooling |
| Interior Daylighting, including solar tubes | - Floor-to-ceiling glass partitions between open and private offices allow daylight to enter all spaces - Open and private offices take advantage of glazing, which lets natural light into each floor - Solar tubes at Level 2 and Level 3 primary gallery spaces introduce natural light within the center of the floor plate |
| LEDs and Energy-Efficient Lighting | - All lighting fixtures are LED; selected with efficiency in mind - Lighting in office areas and classrooms programmed with daylighting controls allowing light levels to adjust based on amount of daylight entering the space - Occupant sensors monitor control of lighting |
| Low window-to-wall ratio and high-efficiency glass | Viracon VNE1-63, Low-E Glazing units: - Visible Light Transmittance: 62% - Solar Energy Reflectance: 37% - Solar Energy Transmittance: 24% - Visible Light Reflectance: 10% - UV Transmittance: 5% - Shading Coefficient (SC): 0.33 - NFRC U-Value:
Window-to-wall ratio: - Total Building: 43,875 sf of building elevation/8,040 sf of glazing area: 18.4% - North: 13,186 sf building elevation/1,310 sf glazing area: 10.0% - South: 12,683 sf building elevation/5,512 sf glazing area: 43.5% - West: 9,003 sf building elevation/802 sf glazing area: 9.0% - East: 9,003 sf building elevation/416 sf glazing area: 4.7% View Dynamic Glazing: - Ability to automatically adapt to changing external conditions - Adjusts from clear state to one of four tint states - Energy-efficient electrochromic glazing units - NFRC U-Value: 0.30 - Shading Coefficient – dependent on tint shade: 0.40 – 0.09 |
Other Benefits
The Student Pavilion is planning for Zero Waste by diverting 90 percent of solid waste through composting, recycling, and surplus sales. ASU is further enforcing sustainable purchasing practices and on-site reuse to avoid waste generation.
During construction, ASU vetted materials generated to maximize diversion by finding methods for material separation and reprocessing. ASU will use the Student Pavilion project to develop best practices for solid-waste flow, life-cycle assessment, and waste hierarchies in future campus construction.
The building design allows users to have a greater role in reducing landfill waste. The Student Pavilion will be the standard for future ASU buildings.
Zero Waste strategies include:
- Deconstructing and handling of materials for maximum recyclability.
- Designing spaces to increase operational waste flow and consumer use.
- Employing standardized Zero Waste stations that accept Blue Bin commingled recycling, Blue Bag materials, e-waste, Green Bin compost, soft plastics, and special materials.
- Finding new remanufacturing processes for hard-to-recycle materials.
- Local reprocessing, remanufacturing, and reuse of materials when possible.
- Tooling equipment, fixtures, and furniture for recyclability and maximum lifespan.
- Use of post-consumer recycled materials in project build, finishes, and furnishings.
