The Leadership in Energy and Environmental Design (LEED) rating system, developed by the United States Green Building Council (USGBC) has multiple categories, including a 2009 version for healthcare buildings. Determination and award of Interior Environmental Quality (IEQ) rating points for Acoustics requires theoretical calculation in design phase of ambient sound, privacy and intrusive outdoor noise relative to allowable criteria or performance validation testing after construction. This case study discusses the required acoustical criteria for IEQ Credits 1 and 2. Floor plans showing patient, procedure, consultation and meeting rooms are presented and discussed with regard to the criteria. Design phase calculation procedures undertaken to document conformance are presented with results. Because conflicts between operational requirements and acoustical criteria create design challenges, commentary is offered about design alternatives that aided or inhibited rating success. Standards and Criteria covered include: Leadership in Energy and Environmental Design (LEED) for Healthcare 2009, a third-party certification and benchmark system created by U.S. Green Building Council (USGBC),Guidelines for Design and Construction of Health Care Facilities, Facility Guidelines Institute (FGI), 2010, referenced in LEED HC 2009 “Sound and Vibration Control,” ASHRAE Handbook of HVAC Applications, 2007 American Society of Heating Refrigerating and Air-Conditioning Engineers, Inc.
