CS-2009 EAp2: Minimum Energy Performance
Hi,
Is it required that the Tenants comply in their lighting designs with the Lighting Power Density requirement of ASHRAE 90.1 2007?
Or is it just for energy modeling purposes that the lighting power allowances for each tenant
space is assumed as indicated in Section
9.6.1.?
Thanks

A portion of our building envelope is historic. Can we exclude it from our model?
For an existing building, do I need to rotate the model?
Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?
Can mezzanines open to floors below be excluded from the energy model?

Our project has a diesel backup generator. Should we include it in our energy model?
Can SHGC be higher in the proposed than in the baseline model?

Only the CS scope of work is covered by a CS submission. So no the tenants are not required to do anything unless required to do so by a provision in the tenant lease agreement. Because it is outside the scope of work we keep this parameter neutral in the models. In the US this is also the code minimum in most places so there would be little danger of the tenant going over this allowance. In other countries this may not be the case.
That said, sorry but I need to lament about the regulatory mindset in the world today. So if you are building a green building what is the right thing to do in this situation? Why is the owner pursuing LEED? Is it to skirt the edge of the rules and get a plaque or to produce an affect?
