LEED CI v3 in a central London building 3 out of 40 floors

Are you using LEED in London and no BREEAM ? Kind of reversed role if LEED goes to UK. The LEED system originated in the early nineties from the UK accreditation system BREEAM

Vivian, You're correct in thinking that you only need to deal with your scope of work. However, for your scope of work, it will be evaluated against ASHRAE 90.1-2007. You will need to provide the detailed calculations necessary for a reviewer to sign off on your project. Paul

So the LEED building is in London and it is for an US client that is part of the Team?

Viv, you just need to look at what is in the tenant scope, but be careful with one important thing - if you have no scope in the project for a credit, then you either have to look at the landlord's provision or the credit is not available. For example, if the toilets are not in the tenant's scope, then you have a number of options: 1) if they are good enough to comply with WEp1 and WEc1, then include them in the calculations. 2) if they are not good enough to comply, you have two options - 2a) you get the landlord to replace them (good luck!) or 2b) you exclude them from your calculations. In the latter case, you can get the pre-requisitem, but not the credits for WE, because you're not including all the fixtures that will be used by the building users. Hope this helps, Eszter
