7group has released an updated version of its well-known (at least within the energy modeling community) ASHRAE 90.1 Appendix G Fan Power Calculator. This tool has been used by countless energy modelers to aid in the development of their Baseline energy models, often for projects pursuing LEED certification. The original calculator included the Baseline model fan power calculations for the 2004 and 2007 versions of ASHRAE 90.1, which were referenced by LEED v2 and LEED v3, respectively. The updated version incorporates changes made in each subsequent version of ASHRAE 90.1, including 2010, 2013 and 2016 in order to continue as a valuable resource for projects pursuing LEED v4 and beyond.
