auxiliary energy and heat pump and relation with Ap aux+DHW/solar heating pump energy.

Hi,
I do understand that the auxiliary energy is coming from the system chosen (AEV and SFP) assigned in auxiliary energy template. and I do understand that the auxiliary energy is related to the energy for pumps and fans of heating, cooling and ventilation systems in the building.
What I dont get ...

breakdown of energy results

Hi,
I am reaching the energy model that I needed as for energy consumption versus internal comfort. I have a question though, when looking at the results in Vistapro, I have the following:
I have heat pump with high efficiency system used and heat recovery ventilation. the breakdown of energy ...

Re: Energy efficient LPD

thanks a lot, that is helpful.
so, do you think I can consider auditorium living quartier as residential dynamic with LPD =5.8w/m2?
any idea of case study maybe for the benchmarking for electric consumption per m2 monthly or yearly in residential?
thanks a lot

Re: Energy efficient LPD

Thank you for the feed back,
I found some data showing LED to be much less LPD yet I cant find a standard to defend my values. I wouldn't mind any standard that would benchmark any area of residential(dining, k*****n, others)
I found ashrae values to be high?
will keep looking
thanx

Energy efficient LPD

Hi,
as per Ashrae 90.1-2010 the lighting power density was 9.7 W/m2
then I found that in another table in Ashrae 90.1-2010 it was 6.9 W/m2
As per Ashrae 90.1-2016 it was 8.3 W/m2

Can somebody tell me what is the value of lighting power density for residential living room , energy efficient house by ...

Re: lighting load

Yes I know there isn't presence detector in IES. I was wondering if there is a factor that I should include value to work as a presence detector function. for example I saw Diversity factor. in the hours that the couple are at home and the control profile set the lighting on (for example at night ...
