Hello,
The HVAC system I'm modelling has two heat-pumps with a water side energy recovery device, so that it is possible to heat and cool (or dehumidify) the spaces simultaneously and recover energy from the condenser. However, I am unable to model this in the software, so I created a spreadsheet to estimate energy savings for space cooling and heating.
When filling out LEED v2009 template for EAp2 pre-requisit, should I fill Table EAp2-5 with wich values?
a) Should I enter values for space cooling and heating that appear in the simulation (without the effect of the energy recovery) and then I fill Table EAp2-10 under section 1.7 - Exceptional calculation measure summary with the energy savings?
b) Or should I enter in Table EAp2-5 directely the values that reflect energy consumption after the heat recovery and do nothing on Table EAp2-10?
Hope I made myself clear.
Thank you all in advance!

This is an exceptional calculation. You should do a.

How do we show exceptional calculations when the new template no longer has a place to input them directly?

You enter the exceptional calculation values in the Performance Output tab of the Minimum Energy Performance Calculator.
