Project History

When Hayden Library was originally built in 1966, it contained 600,000 volumes and served a population of about 20,000 students. At the time, Arizona State University was not yet a decade old. The November 22, 1966 dedication ceremony program states, “The history of library development at Arizona State University reflects the growth of the institution not only in numbers of students but also in the enlargements of its educational mission.” ASU has experienced tremendous growth in the last five decades and the university’s mission has expanded. As stated in its current charter, “ASU is a comprehensive public research university, measured not by whom it excludes, but by whom it includes and how they succeed; advancing research and discovery of public value; and assuming fundamental responsibility for the economic, social, cultural and overall health of the communities it serves.”

The existing building was disconnected from campus malls and had no ground-level entry.

Timeline As a result of ASU’s tremendous growth, Hayden Library is one of eight university libraries in a robust system serving more than 70,000 on-campus students and encompassing over 5 million volumes.

Hayden Library alone receives close to 2 million visitors each year. With the digitization of so many resources, “The library is everywhere now,” according to University Librarian Jim O’Donnell. “Our mission as librarians is to meet students and faculty wherever they are and get them whatever they need, quickly and efficiently, with as few restrictions as possible.”

Need for Reinvention

In its first 50 years, Hayden Library has witnessed the transformation of a library from a place for books to a place for people. According to Tomalee Doan, Associate University Librarian for Engagement and Learning Services, today’s university library “is the place to learn new interdisciplinary skills, meet people, and get involved through experiential learning.

Students and scholars might want to incubate a research idea, think through a problem, or get connected with an expert.”

The existing interiors could not support this program and the project’s design challenge became how to reinvent the existing library in place to minimize environmental impact while giving Hayden Library the contemporary amenities it requires to support current and future students. Strategic investments in new landscaping, glazing, lighting, and mechanical systems allow the library to preserve the best of the past while meeting the needs of the present and future.

Project Scope

The Hayden Library Reinvention at Arizona State University is LEED Platinum. To put that in perspective, of the more than 97,000 LEED certified projects in the United States, 6,546 or 7% are LEED Platinum.

213 LEED Platinum projects are located in Arizona.

Nationally, there are 26 libraries with the designation with only two residing in Arizona. At 252,600 gross square feet, Hayden Library is one of only 13 LEED Platinum projects in Arizona greater than 200,000 gross square feet.

Through an extensive engagement process with the university stakeholders, users, design team, and contractors, a series of project goals were established and refined throughout the design stages: • More student space • Campus connectivity • Active ground floor to showcase library program • Visible and accessible support • Showcase curated collections

As colleges and universities catalog aging building inventory, specifically libraries and other flagship buildings that no longer serve 21st century needs for inquiry, collaboration, innovation and discovery, the Hayden Library Reinvention is a case study for what is possible. By preserving the iconic structure, we were able to vastly reduce the amount of embodied and operational carbon emissions while retaining a sense of place and identity. This transformation allows for a design respectful of context, history, and tradition, while showcasing new and future uses and programs, built around a mix of details that celebrate the past and project the future.

• Diverse, versatile space • Sustainable approach to all aspects of the design • Updated infrastructure • Single phase, continuously occupied, staged turnover

DESIGN FOR WELLNESS

Visual and physical connectivity is restored on Hayden Library’s ground level, allowing pedestrian access from adjacent campus malls. Open, central stairs are immediately accessed from the primary entries to encourage active mobility. The library further supports health and wellness with integrated grab-and-go markets and a ground-floor café.

The indoor environment provides exterior views in upper-level gathering spaces. Stack heights are lowered and spacing is widened to increase visibility and improve accessibility. Sensors modulate artificial lighting in response to available daylight.

Users and staff have override controls and can increase lighting from its initial set points which have been established to reduce energy use.

The reinvention uses low-VOC materials throughout its finish palette and a 100% outdoor air system delivers primary air to spaces with demand control ventilation. Bidirectional infrared people counters for classrooms and CO2 and relative humidity sensors in open spaces ensure HVAC systems adapt to the library’s occupant load in real time.

Acoustics remain critical to library programs.

Acoustic finishes and separation balance transparency, privacy, and future flexibility needs.

Highly absorptive treatments are integrated in noise-generating environments and measures are integrated to control sound from mechanical systems, particularly in acoustically sensitive areas.

“Hayden Library has been the engine of intellectual discovery for generations of Sun Devils. We just turbocharged it for a new generation,” said University Librarian Jim O’Donnell. “The new Hayden is a combination of traditional library and high-tech workspace. It is a dazzling showcase for the university – a place where you can find, interact with, and explore all the riches we have to offer.” The book collections featured throughout the library are university-inspired, strategic in design, driven by data and reader interest, and part of a three-year grant-funded initiative to explore the needs and expectations of 21st century academic library users. Part of a larger library system with changing needs, the Hayden Library Reinvention embodies the system’s vision of its central library as a

DESIGN FOR ECONOMY

Hayden Library’s design celebrates structural materials and limits finish redundancy to produce a beautiful, economically responsible design. New materials are limited but varied to complement reused, existing materials such as 2” thick granite slabs, colorful stained glass, walnut balusters, and terrazzo stair treads. The interior and exterior concrete waffle slab structure, exterior precast relief panels, and exposed aggregate columns were left visible throughout most of the building. Overall, the design reuses 95% of the existing structural elements and building envelope to conserve embodied carbon.

Defined project goals assisted the team in evaluating material applications. An openness to industry feedback allowed the project to source well-crafted, durable materials and manage cost. The exterior precast paver system is raised to conceal infrastructure, provide flexibility, and allow for robust waterproofing over new occupied spaces. A raised-access floor is continued on the interior throughout levels 1-4 to separate power and data and minimize the impact of future changes. This will allow library programs to adapt and grow, without significant future embodied carbon investments. Programmatically, this design provides resilient and varied environments. The extensive building reuse allowed the project’s financial resources to be allocated towards infrastructure upgrades that reduce operational expenses.

DESIGN FOR ENERGY

The existing building operated at an energy use intensity (EUI) of 62 kBTU/sf/yr in 2015.

Iterative energy modeling predicts the renovated library will operate at 42 kBTU/sf/yr under normal use, a 32% improvement. The first five months of 2020 energy consumption data is complicated by altered operations during the global pandemic but indicates that the Hayden Library Reinvention will achieve an EUI of approximately 16 kBTU/sf/yr in its first year of operation.

To achieve anticipated energy savings, the design embraces the challenges of its harsh desert environment and the typically high energy consumption of academic libraries by doubling the density of equipment, ventilation, and users compared to the existing building. High-performance insulated glazing replaces the existing building envelope’s single-pane glazing. Contemporary LEDs entirely replace existing fluorescent fixtures, reducing lighting power density and cooling loads. Chilled beams provide space conditioning, decoupling cooling loads from the demand control ventilation system. Remaining energy demands are partially met by a 249.5 kW rooftop solar array which offsets over 13% of annual energy costs. A robust building management system monitors occupancy to adjust humidity, lighting, and temperature while intuitive controls allow individual users to adjust spaces to meet their unique requirements.

Hayden Library Reinvention

39

DESIGN FOR DISCOVERY

The design team has maintained a close connection to the university and users since 2016 and continues to engage today. Hayden Library’s Reinvention is a model for how Arizona State University frames other projects, conserving embodied carbon while upgrading facilities to meet contemporary program and energy conservation needs. Regular ownerarchitect-contractor meetings have been scheduled for the first year post-completion to maintain active involvement and monitor the building’s performance.

The ongoing pandemic has reduced operational time and skewed building resource consumption. However, post-occupancy evaluation is anticipated either virtually or in-person approximately one year post completion, depending on the evolving circumstances.

Hayden Library’s Reinvention has been shared both within and outside the firm’s practice since design began. In addition to internal presentations and construction site tours, the design team collaborated with ASU to develop sustainability-focused content that will be shared on public building tours. This project has served as a case study for other universities with similar library renovation challenges and professional articles have elevated this project as a strategy for higher education to address their aging mid-century assets. Having just recently completed construction, the team intends to submit for national planning and design conferences with continued client, contractor, and consultant collaboration.

DESIGN FOR CHANGE

The reinvention absorbs the library’s continuing evolution and the university’s space needs. The existing, distributed circulation cores can accommodate a variety of layouts as evidenced by the reinvention’s diverse floor plans. A new centralized bank of modern elevators supports accessibility and empowers future use. A new addition to house previously distributed mechanical systems frees up critical floor area and allows the program to breathe within the open floor plan. Raised-access flooring allows additional transformation, and power and data have been separated in the floor and ceiling to eliminate crossover and reduce future rewiring impact.

The building’s 21’-8” x 22’-8” structural grid promotes circulation along its major axis and the structure itself is oversized to accommodate two additional floors if necessary. The floor-to-floor height is increased at the ground floor to promote engagement and showcase programs. Each floor accommodates gathering spaces at many scales, from two-person phone rooms housed in the old elevator shafts to dividable 150-person classrooms. Emergency and standby power is obtained from the existing central plant and the building is connected to medium voltage generators. Backup power is limited to essential systems and the rooftop solar array can be utilized to provide power directly to the building.

Retain and Renew

Hayden Library’s reuse retains the embodied energy and value of its structure and reveals the character of the building in a new light for a new time. Reinvention allows for a design respectful of context, history, and tradition, while showcasing new and future uses and programs, built around a mix of details that celebrate the past and project the future. By creating equitable environments, engaging campus malls, and reinforcing connections on the site and within the building, the library repositions itself to support students at the heart of campus, reconnecting itself to its place.

The reinvention embodies best practices for how existing buildings can be renovated into modern high-performance buildings and will leave an environmentally responsible legacy for generations to come.

• The site location along walk-only campus malls minimizes environmental impact and demand for vehicles.

• 100% of the roof area is highly reflective and helps mitigate the urban heat island effect.

• The building demonstrates 37% indoor water use reduction compared to baseline.

• Native landscaping and high-efficiency irrigation systems reduce potable water used for irrigation by 80%.

• The building anticipates 47% energy cost savings annually.

• The building’s 249.5 kWDC rooftop PV array offsets 13% of annual energy costs.

• 100% of the paving materials on-grade are highly reflective and help mitigate the urban heat island effect.

• 95% of the existing building envelope and structural system were preserved in the renovation, keeping carbon intensive materials out of the landfill.

• 80% of construction and demolition waste was diverted from landfill.

• 22% of the project’s materials are recycled content.

• 12% of the project’s materials were sourced within a 500-mile radius.

• 76% of the new wood products are FSC certified.

DESIGN FOR ECOLOGY

As part of ASU’s Tempe Campus, Hayden Library is sited in the lower Sonoran Desert, an incredibly diverse, arid landscape. The design protects existing, mature mesquite trees and adds climate-appropriate plants to achieve a responsible, water-conscious design.

The removal of palm trees from the existing site and replacement with canopy trees increases biomass, shade, and creates nesting habitat. Permeable pavers allow the limited amount of available rainfall to slowly nourish the landscape rather than run off. The design connects people to the seasons with deciduous trees and blooms that change throughout the year and incorporates salvaged granite planters to connect the current design to its historic roots.

Site lighting includes only full cut-off fixtures and all building-mounted exterior lighting is captured by deep roof overhangs, reducing light pollution. Upperlevel slot windows allow for daylight and views at the building perimeter but are less impactful to flight paths, reducing bird collisions. The exclusive use of highly reflective paving is particularly impactful in the desert to reduce the heat island effect.

Equipment is contained within an acoustical barrier designed to complement the existing building in scale, material, pattern, and finish and prevent noise from interfering with pedestrian paths.

DESIGN FOR WATER

The landscape design incorporates native and adapted species maintained by a high-efficiency irrigation system that is anticipated to reduce potable water consumption 80% from baseline. Stormwater is directed to a nearly 20,000 cubic foot below-grade retention vault with an open bottom. The project team carefully sited the vault around existing footings, retaining walls, and campus infrastructure tunnels to meet current capacity standards and mitigate stormwater issues from adjacent sites, doing good for not just Hayden Library, but for the campus as a whole. Existing building roof and new plaza roof drains are directed to the vault and drain directly into permeable ground layers.

Low-flow fixtures and fittings are used throughout the building and result in a 37% water savings from baseline. The new domestic water system is configured to tie directly into a future non-potable water system, allowing for additional offsets in domestic water use with minimized schedule and new equipment costs. In the future, non-potable water will be provided to all water closets and urinals, and provide makeup water to mechanical systems, while potable water will be provided to all other fixtures.

The original building concept of a tower surrounded by a moat no longer supported the university’s programmatic needs, and was also overwhelmed by campus stormwater. Water would flow towards the library without a way to safely manage flooding in the event of a major storm. The new approach of an open-bottom stormwater retention vault brings the capacity to current standards and helps to mitigate stormwater issues from adjacent sites, improving not just the project, but the campus as a whole. Existing building and new plaza roof drains are directed to the vault and drain directly into the permeable ground.

DESIGN FOR RESOURCES

Preserving 95% of Hayden Library’s opaque building envelope and structural system has conserved over 9,000 metric tons of embodied carbon in place.

The retrofit of its exterior glazing system and a new addition to house high-performance mechanical systems invested 550 metric tons of embodied carbon to reduce ongoing energy demands. Existing interior concrete and terrazzo stairs were cleaned and remain intact. The new design embraces unique details of the existing building, such as stair balusters and textured wall tiles, and builds the new palette around these features in addition to considerations for environmental stewardship, durability, and recyclability. The concrete waffle slab structure was left exposed in many areas to minimize interior finishes and existing stained glass was repurposed. Nearly 22% of the project’s new architectural products consist of recycled content and 12% of the project’s materials were sourced within 500 miles. New wood product selections prioritized the use of Forestry Stewardship Council certified products with 77% of the wood carrying this designation.

Construction prioritized waste diversion with 80% of the project’s waste stream diverted from landfill.
