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?

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?

CS-2009 EAp2:Minimum Energy Performance

Proof on Exceptional Calculations of Energy Modelling

Our LEED project has adopted lighting control as energy-saving strategy for parking garage and documented as exceptional calculation in EAp2 and EAc1. Soon we received USGBC's comment asking for project references to demonstrate that these are not standard practices.

Original texts are as below:

“...the Baseline case description should provide evidence that reduced lighting schedule is not standard practice for similar newly constructed facilities (three facilities built within the past five years of the project registration date) where the project is located.”

Since it's quite impossible for us to have information about buildings we did not build, are there any alternatives to address the problems? Have anyone encountered the same situation before?

Many thanks!

Kathy

One simple option is to show that local utilities provide incentives for the ECM. If the utility is paying people to do it, it's not standard practice.

Has anyone on the project team or anyone on the owner's side been involved with a project where a parking garage has been installed? These do not have to be from projects that you built. This experience can come from the company that designed the lighting system for the garage or designed the garage itself. Have they done any local projects? Can they write a letter to demonstrate that this is not standard practice? When preparing an exceptional calculation the project team is required to justify the baseline choice. In some areas this type of control is required by code. If no one has any local project experience then you will need to provide some other justification for the baseline choice that demonstrates that it is not standard practice in parking garages in this area.

Thanks Christopher. That sounds workable. We will try to see if there are any local incentives made for this strategy.

Thanks Marcus! We have project references on the country but not the exact city our project is built. That's why we are struggling to provide any references. Thanks for your suggestions! I guess we will look for other justifications as an evidence.
