Re: [TRNSYS-users] Light power requirement estimation



Dear Arnaud,

I think the best way to do that is to estimate lighting power you need with another soft and try to put value you find in your thermal simulation as internal gains.

Good evening everyone,

I would like to know how I should I simulate the lighting power required in
my building.

1/ Can I say that the artificial light will be needed when the total
irradiance is below a certain value? 100W/m2, 200W/m2?

2/ The building is a big house (350m2) but most of the year there is only
one occupant. Can I say that:
Power = ( Number of occupant at t=to * Total area/max number of occupant)*
average light /m2

If yes, does anybody know a ball park for the average light in W needed for
one m2?

Thank you!
