case study: james hall, a greener home for greener sciences
DESCRIPTION
The project features several strategies to integrate sustainable architecture and engineering improvements into a historic structure. We will investigate questions of design strategies, LEED Certification, performance measurement, products and materials, and other critical questions.Sited on the main historic quad of the campus, the building was constructed in 1929 and has been housed in the Earth Science and Natural Resources programs since 1970. Interweaving the retention and restoration of existing materials alongside new efficient technologies, the rehab and expansion included refinishing existing windows, implementing high-performance envelope strategies, and shoe-horning ventilation within the existing shell. The HVAC systems included both chilled beams and highly efficient energy recovery systems.The collaborative and integrated team included UNH Department of Facilities Design and Construction, EYP Architecture and Engineering, Le Messurier and Shawmut Design and Construction. This roundtable is part of the Sustainable Design Case Study Series at NEXUS. Learn more at http://www.nexusboston.org/news/casestudyroundtables.TRANSCRIPT

Agenda
/ Project Goals
• To adapt, modernize and expand James Hall to create avibrant environment for the Earth Science and NaturalResource Departments
/Campus Goals
• To connect easily with other campus buildings, particularlyscience buildings
/Building Goals
• Preserve the essence of Eric Huddleston’s architecture whileadapting James Hall for modern science• Reflect the importance of the natural environment to theacademic departments occupying James Hall by theenvironmental sensitivity of the new work• Achieve LEED certification
/Program Goals• A project that is the best long term value for the University
within the available resources

SustainabilitycurrentlyInherent to UNH Estimated 18 – 22 LEED credits are achieved based on
UNH current standards
Common Practices as LEED credits1. Measurement & Verification through BAS – Controls2. Site Selection3. Development Density & Community Connectivity4. Alternative Transportation5. HVAC and energy management6. Water Use Reduction7. Interior Lighting and Controls8. Recycling9. Local Transportation10. Bicycle parking / storage11. Specific parking for low-emissions vehicles (Eco Cat,
Zip Car)
Credits currentlyProblematic toUNH 42 – 46 credits are problematic or not inclusive to UNH
standards
1. Exterior lighting, Sternberg fixtures – light cut-offsdo not meet LEED requirements
2. Lacking in typical materials used with recycledcontent
3. Lacking in typical materials used with no off-gassing4. Construction waste management needs to be
improved5. Material re-use needs to be increased6. Low emitting finishes need to be augmented in
standards7. Commitment to Regional Materials8. Commitment to Certified
Wood Products
Revised UNHStandards
Enhancing the construction standards has lead to a review ofUNH’s overall planning, design and construction process witha new web-site detailing changes in progress scheduled forJune publication.
- Commitment to the documentation process
- Education to operations and end users about what a LEEDbuilding is and means
- Green Scorecard for all projects regardless of formal LEEDcertification
- Commitment to Commissioning as a standard procedure forall building projects to ensure energy efficiency designed isachieved
