I am working on a project in the UK and the client wants to know what the alternatives are to ASHRAE 90.1 for energy modelling to demonstrate compliance with EAp2 and EAc1. The document "LEED Reference Guide for Green Building Design and Construction with Global ACPs" says that projects can use USGBC approved equivalent standards to ASHRAE 90.1 but I can't find what these are.
Does anyone know if there is a list of "USGBC approved equivalent"?
Has anyone had any experience in demonstrating complaince using a "USGBC approved equivalent" standard?
Are the requirements for EAp2/EAc1 any different in terms of the potential to use alternative local standards?
Many thanks!

There has been some equivalency work inside the US but not outside that I am aware of. There is no list.
Equivalency in this case is a rather significant research project. It is typically conducted with energy models evaluating many different building types in all potential climate zones. This would be done for 90.1 and then the other standard you wish to determine is equivalent.
More information and a complete list of accepted ACPs can be found here - http://www.usgbc.org/sites/default/files/LEED%202009%20RG%20BD+C-Supplem...
