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 its predecessor (LEED Silver spec) Built using modular construction Approximately $4.7 million Seeking Passive House Certification

5 What is Passive House Worlds 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.htmlhttp://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
