FAQs about EAp2:
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?
How do I provide a zip code for an international location?
For a project outside the U.S., how do I determine the climate zone?
For a project outside the U.S., how do I determine the Target Finder score?
Do hotel rooms need automatic light shut-off control?
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?
Which baseline HVAC system do I use if my building has no heating or air conditioning?
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?

Do you mean an instantaneous water heater? If so that is covered by 90.1.

thanks Marcus, somehow over here, we unable to get any instantaneous water heater aka home electrical heater with Energy Star label (whom i believe , tested under DOE 10CFR 430).
we might able to find electrical heater with local energy efficient rated product. do you think this gbci will accept this?
Commercially is expensive to ship few units of such from US to here, and yet to mention, local has it own energy efficient product too. Thought?

The water heater you use does not have to be Energy Star. It does need to meet the minimum efficiency from Table 7.8 but it does not appear that an electric instantaneous is covered in this table so it would be exempt from any minimum efficiency.
