This project is a laboratory building being constructed in an existing building. As part of the design process, the Labs21 EPC and the LEED Draft Application Guide for Labs were used as a guideline for sustainable design features of the labs. Towards that end, we are proposign the following for ID Credit 1.1: ID CR 1: Laboratory Safety: Intent: Insure the health and safety of laboratory employees Requirements: Design laboratories to ensure contaminants are contained and workers are protected (relates to AGL EQ Pre-Requisite 3 and Credits 9.1 and 9.2) 1. Ensure minimum requirements for safety and worker protection are met through compliance with ANSI / AIHA Z9.5 latest version. 2. Conduct Fume Hood commissioning including ASHRAE-110 method for testing performance of Laboratory Fume Hoods (latest version). This includes field testing each of the new fume hoods as well as each of the existing fume hoods scheduled to remain in the new construction. 3. Design all alarm systems in the laboratory to be inherently self-identifying and fail-safe Submittals will be 1. Letter certifying ventilation design is in compliance with ANSI / AIHA Z9.5 latest version 2. Specifications and Fume Hood Commissioning report 3. Fume hood controls and alarm system diagrams and schematics from design documents Please advise if this suggested point will meet the requirements of the Innovation in Design Credit 1 and will be likely to be awarded to this project.
ASHRAE 110 commissioning of fume hoods is acceptable for an ID credit on your project. To meet the requirement, ALL fume hoods on the project must be commissioned, and commissioning must occur with permanent HVAC systems in place and operating. Your team should be aware that ASHRAE 110 commissioning requires tracer gas testing, which may require the discharge of relatively large quantities of Sulfa Hexafluoride, a climate change gas. Teams using ASHRAE 110 are encouraged to seek alternative testing methods involving other gases, or the use of higher sensitivity sensors so that lower quantities of gases can be used. *Please note a previous ruling to this CIR was posted and has since been revised by the IEQ TAG.* Applicable Internationally.
