  1. Building for the Future: Designing a Passive House Residence Hall at Emory & Henry College Jesse Freedman Joint Energy Manager Hollins University/Emory & Henry College

  2. Introduction • Who I Am • What We Did • How We Did It • What We Plan To Do

  3. Who I Am • Joint Energy Manager • Made possible by a generous grant from the Jessie Ball duPont Fund • Direct a three-year collaborative energy conservation project • Two hours (120 miles) between the two campuses • Modeled loosely on the Five Colleges joint energy manager

  4. What we did • Second of three residence halls • Nearly identical to it’s predecessor (LEED Silver spec) • Built using modular construction • Approximately $4.7 million • Seeking Passive House Certification

  5. What is Passive House • World’s most stringent building energy code • Airtight building envelope (<.6 ACH50) • 4.75 kBtu/sf/yr heat demand • 38.1 kBtu/sf/yr primary energy • Heat recovery ventilation Source: http://www.passivehouse.us/passiveHouse/PassiveHouseInfo.html

  6. How we did it • R-30 walls, R-50 roof • Triple-glazed windows • Ground-source heat pumps (15 tons) • 18 Energy Recovery Ventilators • Air-tight building envelope • preliminary blower door test <.2 ACH50

  7. Building Envelope

  9. Modular Construction • Click here to see a video of the construction process

  10. Fiscal and Energy Performance *Hickory Hall based on modeled data; average based on ASHRAE 90.1-2013

  11. What we plan to do • Comparison energy study of Elm and Hickory • Short-term and longitudinal behavior study • Measure student behaviors and academic performance
