FAQs about EAp2 :

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?

Can I claim exterior lighting savings for canopy lighting even though a baseline model cannot include shading elements?

The project is built on a site with existing exterior lighting installed. How should this be accounted for?

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?

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

Can the Trace 700 'LEED Energy Performance Summary Report' by uploaded to LEED Online in lieu of the Section 1.4 tables spreadsheet?

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?

CS-2009 EAp2:Minimum Energy Performance

heat recovery in baseline

I'm using v2009_Minimum Energy Performance Calculator_v09.xlsm

In the tab "Air-Side HVAC" it specifies that energy recovery is required "For Baseline, any individual systems where supply airflow rate exceeds value in Table 6.5.6.1". It seems that it is reffering to addendum e, since according to the original version of ASHRAE 90.1-2007 as for baseline model energy recovery is modelled when the system has both a design supply air capacity of 2400 L/s or greater and a minimum OA of 70% or greater of the design supply air quantity.

Is the use of addendum e mandatory or can I consider the original version of ASHARE 90.1-2007?

I know that addeneda are not mandatory generally, but I'm wondering whether a LEED interpretation about this particular issue exists.

Best Regards

It is not mandatory. The MEPC was originally created for LEED v4/90.1-2010. It was then modified back to 90.1-2007. I think some stuff was missed.

what version of ASHRAE 90.1 the eQuest 3.65 build 7175 creates the baseline building?

eQUEST does not automatically build the baseline building.
