Dudley Hall and Lambertus Hall
LEED Project Summary
Dudley Hall and Lambertus Hall serve as a gateway to the West Lafayette campus and combine cutting-edge studies in manufacturing and engineering. The complex houses laboratories for Purdue Polytechnic’s School of Construction Management Technology, School of Engineering Technology, Department of Computer and Information Technology and Department of Computer Graphics Technology, as well as faculty offices.
The complex was designed to be as high performing as the programs inside by achieving the Leadership in Energy and Environmental Design v4 (LEED) Silver Certification. LEED is the most widely used green building rating system in the world. It provides a framework for healthy, highly-efficient and cost-saving buildings, which directly contributes to progress towards the Physical Facilities Sustainability Master Plan goals. The list below illustrates key examples of LEED sustainability features that were incorporated into the complex.
Integration
Integrated design, where different disciplines and project stakeholders work together to explore design solutions, is critical for sustainable buildings. For Dudley and Lambertus Halls, architects, engineers and representatives of Purdue collaborated early in the project to identify sustainable strategies, especially ways to save energy and water.
Drink Up
Electric water coolers are available throughout Dudley and Lambertus Halls with integrated bottle fillers to promote the use of refillable bottles, which in addition to saving water, reduces the amount of waste resulting from the use of bottled water.
Saving Water
Dudley and Lambertus Halls use water efficient plumbing fixtures to help reduce indoor water consumption by 30% compared to the baseline design. The complex also utilizes a landscaping strategy with native plants that reduces irrigation water use by 50%. In addition, water-cooled equipment uses a closed loop system instead of discharging cooling water to drains to save a precious resource.
Easy Access
The complex is located at the forefront of campus with easy access to plenty of shops and services. Visitors can walk or ride a bicycle down the expanding campus bike path network or hop on one of the many public bus routes. The bike path network is part of Purdue’s goal to double miles of infrastructure on campus by fiscal year 2025.
Sustainable Site
The LEED rating system encourages projects to be located on sites that respect the relationship between buildings, infrastructure and ecosystems. Before the first shovel hit the ground, civil engineers and landscape architects surveyed the site for climate, sunlight, pollution sources, topography and more to develop design strategies. Purdue University has a goal of eliminated combined sewer overflow (CSO), meaning engineers separated storm water from sanitary sewage to ease the burden on West Lafayette’s water treatment facilities and keep waterways clean.
Daylight Power
Louvers, or shutters with slats spaced at a fixed angle, on the south side of the building let daylight in while keeping out excess heat and glare. Using daylight is a strategy for reducing lighting energy, and having an outside view has proven to have positive effects on mood, concentration and vision health.
Eco Materials
The materials used to construct Dudley and Lambertus Halls were selected with care to reduce environmental impact. Many of the products used have Environmental Product Declarations, which include information on the product’s life cycle such as raw material sourcing, transportation and manufacturing. Health Product Declarations, on the other hand, disclose a product’s ingredients, including any that might be harmful to human health. This building’s materials take into account environmental and health impacts, resulting in a more sustainable, healthier place.
Keep It Clean
Many recycling stations are available throughout the complex. The ethos of recycling started before construction even started with 84% of construction materials diverted from the landfill through recycling and reuse.
Efficient Design
When it comes to using energy efficiently, the complex reduces energy use by 16% through features such as all LED lighting, energy recovery HVAC systems and shading to reduce solar heat gain. These features can help reduce energy use, lower operating and maintenance costs, and improve indoor air quality, thermal comfort and access to daylight.
Walk Around
Dudley and Lambertus Halls were designed to create a pedestrian-focused experience. Trees help separate sidewalks from the street, parking and loading docks are tucked away, and the ground floor is welcoming with plenty of windows and entrances.
