Currently completing an SBEM with retail units that have a toilet, kitchen and eating area. Kitchen and Toilet area has no heating or cooling in it and the restaurant eating area has heat pumps so there should be a notional heating value within the compliance report?
Getting the Part L to Pass, however looking at the report there is no notional heating value but there is an actual heating value present. Cooling values also seem fine.
Tried it without Heat recovery and any ventilation and that seems to bring the heating value to a reasonable level, thought it could be the angle from north as to why there is no notional heat value. Is there an issue with my model?
Thanks
Josh
Hi Shane,
All the retail units are next to each other and require separate EPC's and all have the same mechanical/electrical input. Yes the value is currently being shown as zero except one retail unit for some reason.
And yes I am referring to the Energy Consumption by End Use kwh/m2 section of the Compliance report.
Hi Josh,
Just to check, are you running the calc on a zone by zone basis? I ask as quite a lot of them are designated as 'No heating or Cooling' in HVAC data.

I am selecting each individual in order to get an individual EPC for each unit and also selecting the units by 3 rooms each (Unit restaurant, Toilet & kitchen) in order to differentiate each zones heating or cooling system. I am selecting one retail unit at a time for example- Unit 7 WC/ Unit 7 Kitchen & Unit 7 so I can add hot water to the restaurant WC and kitchenette areas.
The WC & Kitchen areas have no heating or cooling but the unit restaurant area has heating and cooling only. So I'm not sure as to why there is zero notional heat load.
Thanks Josh,
You'll need to check these results with your accreditation scheme provider as I can't see anything untoward from a Hevacomp point of view - there are no errors and the software seems to be working fine. They will be much better placed to advise.
