[TRNSYS-users] Artificial lighting

[hotline]

Hi Maurizo,
 
the confusing part is that there are not only several ways to define it but also different control strategies possible.
 
You may select the following:
 
Related floor area:     1 m²
Total heat gain:         100 W/m²  
convective part:         10 %
control strategie:         Define e.g. an input or schedule when the light is on  (e.g. depending on the horizontal radiation outside)
scale:                         1*SCHEDULE USE  (schedule use defines when the room is used an the light might be on e.g. workday 8 am to 8 pm)
 
The resulting heat gain is:
 
"convective resulating heat gain" = "Related floor area" * "Total heat gain" * "convective part" * "control strategie" * "scale"
 
"radiative resulating heat gain" = "Related floor area" * "Total heat gain" * (1- "convective part") * "control strategie" * "scale"
 
If "scale" and "control strategie" is set 1 you a thermal load of 100 W for your room.
 
Sincerely,

	Dear all,
	 
	I have a problem with the definition of TRNBUILD internal gain "artificial light". 
	I don't understand the meaning of the required inputs&parameters.. So if I have, for example, the simple situation of an a incandescent lamp of 100 W in a room of 9 sqm I don't know how I have to set the different fields. 
	 
	Can anyone give me some advices on how to solve this problem?
	 
	Thanks,
	 
	Maurizio
