How commonly are the 90.1 mandatory compliance forms submitted as part of EAp2/EAc1?

The Section 9 space-by-space method does not include residential space types. What should I use?

Can the Passive House Planning Package (PHPP) be used to energy model for LEED?

Is it acceptable to model a split-type AC with inverter technology compressor as a heat pump, like modeling VRF?

A portion of our building envelope is historic. Can we exclude it from our model?

Which baseline HVAC system do I use if my building has no heating or air conditioning?

For an existing building, do I need to rotate the model?

Our project has a diesel backup generator. Should we include it in our energy model?

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Can SHGC be higher in the proposed than in the baseline model?

Our process load is higher than 25%. Do we have to justify that?

Do I need to justify the electrical and fuel rates I am using in my model?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Is this new compliance path likely to have any effect, direct or indirect, on prereq/credit documentation?

I think it will eventually. This is a new compliance path for demonstrating code compliance with 90.1 so it will eventually bring together code compliance and LEED documentation within the same methodology. That probably won't happen until states start to adopt 90.1-2016 which is not yet out. It will be a year or two at least and then only in the very few states that automatically adopt the latest version of the standard. Most states don't do so. In order to work for LEED documentation the USGBC would need to develop the appropriate thresholds for percent savings relative to this new baseline. This also fixes a firm baseline so LEED 2009 projects, v4 projects and future LEED projects will be comparable to this baseline. It will also hopefully get net zero on the scale for awarding points within LEED so that they can be appropriately awarded. Right now something like 50% better than 90.1-2007 earns all the EAc1 points available. If you get to 100% there is no additional reward within the point system. This is a good step in the right direction.
