FAQs about EAp2 :

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?

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?

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?

Dear All,

Good Day !

We have used agricultural waste - rice husk as biofuel in Steam boiler. We have enough documents to claim it in renewable energy such as Harvested with in 25 mile and 10 Yrs Contract, Pollution control norms compliance and the rice husk is burned / diverted to landfill if not used in here

We get the rice husk in free of cost so we have entered thermal energy consumption (Steam consumption / Rice Husk Energy ) in EA p2 and the rice husk cost as zero in both case.
However, We have natural gas backup, Can we document the cost of natural gas in baseline case and Ricehusk in Design case (Fuel Switching option)

Rice husk is a form of renewable energy (biofuel – agricultural waste) and we want to claim the advantage of renewable energy in EACR2.
Can we consider the cost per kWh of natural gas for rise husk while considering it in EACR2 and take the advantage accordingly?

Yes. You can model gas in the baseline system and account for the free biofuel in the proposed. I am not sure how you would model the rice husks in the proposed case? You could model gas in the proposed and then just zero out the cost in the renewables section of the prerequisite form.
