CS-2009 EAp2:Minimum Energy Performance

Option 1: Without tenant, does not meet pre-requisite.

The client is developing without a tenant and is deferring major HVAC components to the tenant build-out (air handlers.) Without air handlers, the energy model does not meet pre-requisite with option 1. Project is too large to use other options. With no tenant in place, the client is not able to provide signed lease with language specific to performance. What are other options to acheive pre-requisite? This tenant signed lease does not seem to be in favor of developer clients, which was the purpose of CS to begin with?

I am not sure it needs to be a signed lease. Basically the developer needs to have in place a set of tenant guidelines that will be enforced once you have signed a lease. So for example, limit the tenants to something less than the 90.1 lighting power densities and you can claim credit for those savings.

You might also look at the adjustments you can make to the modeling results explained in this document -http://www.usgbc.org/ShowFile.aspx?DocumentID=10130
