NC-2009 EAp2:Minimum Energy Performance

Energy source - pallets

Greetings

We have a project where the heating plant consists of boilers using wooden pallets as an energy source. They’ll serve Heating and DHW on 100%. The pallets will be purchased from somewhere off-side.

We’ve been checking the ACP EApc95 v3-LEED 2009 where it has been mentioned that there is a possibility to obtain up to 26 points.

We are in possession of the latest update of ISO Standard 16246:2013, which is now named as ISO 52000-1:2017.

We’ve also downloaded the spreadsheet EApc95 Energy Metric ACP.

The questions still are:

  1. Is there some explanations or instructions on how to fill-in this spreadsheet.

  2. How the possible points are to be evaluated, is there some table?

  3. Since the energy rates in Proposed and Baseline are supposed to be equal, how practically to get any advantages if the pallets appear cheaper than the diesel oil, which is the traditional energy source in this region.

Any advice/guidance in these directions will be highly appreciated.

Thanks

1. I don't know of any other instructions. It looks pretty self-explanatory to me. 2. You use the same percentage based table as you would use for cost under EAc1. 3. That comparison is not allowed in LEED under any scenario. Both the baseline and proposed need to use the same fuel. You may get a somewhat different percentage savings from some of the other metrics in EApc95. However, your reasoning for using a different metric than cost should not be solely based on the fact that you get a better percent savings than if you used cost.

Hi Marcus, Thanks for the reply. The reason for questioning about filling-in the EApc 95 calculator are:
  • Cost – it’s clear that the energy cost will be identical, but which one- the pellete’s cost or the diesel’s cost.
  • Source-to-site ratio – should we enter here the respective value for each separate energy source and if it should be entered identical – which one to enter
  • Greenhouse gas emission factors – again, should we enter here the respective value for each separate energy source and if it should be entered identical – which one to enter
Our question might appear kind of foolish, but we’d like to avoid any eventual misinterpretation while pursuing this ACP. Your opinion on the matter is highly appreciated. Thanks.

Pallet cost. This ratio varies from fuel source to fuel source. The one with the biggest disparity is electricity. Most other have little to no difference between the two. For each fuel source.

Thanks a lot, Now is clear
