2363 Level 3 Design Homework Question..

[InconspicuousAC]

Hey guys!

We've been given a list of mock questions to do as homework for the level 3 design section, and i've come across one i just can't get my head around. Any help would be amazing. I've been at it for hours and sums and formulas are now just all blending together to create one big notepad of nonsense.

Q: A Drawing office measures 50m x 40m and is to be illuminated with 20, 1000W high pressure murcury vapour luminairs each having an efficacy of 59 lm/W. If the utilisation factor is 0.6 and the light loss factor is 0.8, calculate the illuminance. Show how you might fit them in the room. If the Space-to-height ratio is 1.25:1 determine the mounting height.

It's become my nemesis. Please help showing working out so i can make sense of it.

Many thanks in advance for anyone taking the time to assist!

Cheers,
Andy

Can you show your workings out and then we might be able to see were you are going wrong.

For the spacing I would do 4 rows of 5 fittings spaced 10M apart in both directions and a 5M space between the last fitting and the outer wall.

do you mean 2365 assessment 615? the hotel and pool/cafe?

if so, is the homework for that or the other exam that goes with it? i've just been given a date of 2weeks time to do the exam, but have no idea what this exam is or consists of.
although thats no surprise with my training provider!
