Inquiry

Our system currently relies on an engineered natural ventilation system to provide outside air to the apartment units, a design permitted by EQ-PR1 which states "Naturally ventilated buildings shall comply with ASHRAE 62.1-2004, paragraph 5.1." Although we do not meet the basic requirements of ASHRAE 62-2004, the standard incorporates an exemption allowing the "authority having jurisdiction" to approve engineered systems other than those explicitly described in the Standard. Our natural ventilation system has been designed in accordance with the City of St. Louis requirements, and as such is in compliance with paragraph 5.1 of 62.1-2004. Therefore, we believe our design meets the requirements of LEED EQ-PR1. Can this project satisfy IEQ prerequisite 1 through the use of an engineered natural ventilation system approved by the authority having jurisdiction?
