Labs21 Environmental Performance Criteria | Version 2.2 | August 2008
The Labs21 Environmental Performance Criteria (EPC) is a rating system for use by laboratory building project stakeholders to assess the environmental performance of laboratory facilities. The EPC leverages and builds on the U.S. Green Building Council's widely used LEED Rating System, extending it to set appropriate and specific requirements for laboratories.
The EPC leverages and builds on the U.S. Green Building Council's widely used Leadership in Energy and Environmental Design (LEED) Green Building Rating System for New Construction (LEED-NC) Rating System (available at: http://www.usgbc.org/), extending it to set appropriate and specific requirements for laboratories. The EPC is a public domain document that is available for anyone to use as they see fit. Labs21 does not provide a project certification process for the EPC. However, many of the EPC credits may be pursued as innovation points under LEED-NC.
The Labs21 EPC Version 2.2 follows the format of LEED-NC Version 2.2. When not mentioned, LEED-NC credits and requirements are assumed to remain the same. This document only contains additional credits (over and above LEED-NC credits) as well as modifications to LEED-NC credits. For example, in the Sustainable Sites (SS) category the LEED-NC prerequisite and credits SS-1 through SS-8 remain unchanged. Labs21 EPC proposes an additional credit (SS-9), Safety and Risk Management with a potential two-point credit. Therefore, the Labs21EPC must be considered in conjunction with LEED-NC Version 2.2.
Note that the EPC increases the number of possible points from 69 to 85. The EPC does not specify threshold values for the ratings of silver, gold and platinum because Labs21 does not provide a certification process.
Changes from EPC 2.1
EPC Version 2.2 is primarily an administrative update to align with the evolution of LEED-NC and ASHRAE Standard 90.1, and involved the following changes from the prior version:
- Energy & Atmosphere (EA) Prerequisite 2 and Credit 1 now reference ASHRAE Standard 90.1-2007 Appendix G. The thresholds for minimum compliance and improved performance have been changed to reflect the changes in LEED-NC that require a minimum percentage improvement.
- The percentage thresholds for EA Credit 2 have been modified to reflect the changes in LEED-NC that now include all energy loads (not just regulated loads) in the calculation.
- Water Efficiency (WE) Prerequisite 1 now exempts equipment that has a flow rate lower than 2 gallons per minute.
- Indoor Environmental Quality (EQ) Credit 6 no longer has any modifications to the LEED-NC credit, as LEED-NC Version 2.2 removed the specific requirement for operable windows.
