Great to see some AS1158 tutorials going up-nice work on the clip! There are a few areas you could refine to improve it further. Here’s some feedback to consider: AS1158.2 outlines the methodology for computer-aided calculations, so here are a few key aspects you missed that can significantly impact establishing compliant values, particularly for vertical illuminance: Vertical Illuminance: The measuring plane is valid up to 7 metres from the extremities of the area under consideration. Horizontal Illuminance: The measuring plane is valid up to 2.5 metres from the extremities of the area under consideration. Maintenance Factor: Include details on how to establish this, factoring in Luminaire Dirt Depreciation (LDD) and Light Source Lumen Depreciation (LLD). Control of Glare and Upward Waste Light: This is addressed in section 3.7 of AS1158.3.1 and includes the Discomfort Glare Index, Limitation of Luminous Intensity (LLI), and Upward Waste Light Ratio (UWLR). The standard doesn’t communicate this well, but these are as relevant to compliance as the illuminance levels. The standard assumes that asymmetric lighting is installed as photometered and without tilt, which is reflected in the equations governing discomfort glare and luminous intensity. Tilting luminaires alters the range of vertical candela angles, shifting peak intensities relative to the observer. For example, with asymmetric lighting, its good practice to specify the luminaire based on the direction and angle required for peak intensity without the need for tilt. Tilting changes this peak, often exceeding the thresholds set by the Discomfort Glare Index and Limitation of Luminous Intensity. In your example, a 10-degree tilt would almost certaintly push intensities above the fixed 65-degree observer angle, exceeding both DGIP and LLI thresholds. To avoid this, a good approach is to reference the 2D polar diagram and adjust the tilt to keep peak intensities as close to the 65-degree line as possible without exceeding it. In my experience, asymmetric fittings leave only 3-5 degrees of flexibility before becoming non-compliant. When i teach this stuff, I i teach tilt at the same time I teach about luminous intensity and in almost all cases, the luminare is designed to be specified as its photometerd, unless its aimable. It’s also worth noting that glare and obtrusive light mitigation are often not well understood but are key to meeting compliance and environmental considerations. Educating others on these aspects-particularly the Discomfort Glare Index, Limitation of Luminous Intensity, and UWLR-can help bridge this gap. If you’d like, I’m happy to walk you through the clacs and methodologies in more detail over a Zoom session-just inbox me. Keep up the good work on these videos!

Sir mujhe class join krna hai

please make one video on panel & DB costing & estimation

Sir i want to join this course

Can i get a link to the course

very fast explanation 🙄

That's why we appreciate Indian engineers they shared everything they know.in Ethiopia no one can share what he knows

THANKYOU SO MUCH!

Hindi me bolo na

Nice🎉

Sir cable size bhi bata dete

IS THERE ANY INSTALLMENT AVAILLABLE FOR THIS COURSE

Is it according to Uae standard or indian standard

Thanks Sir... Its really very Elegant Video and yours presentation as well...

How can we change the Boom length in this area calculations?.

Sir i have seen your G+5 video but you didn't tought about ACCL (changeover) in that video. I want a video on it,when will you make your next video ?

may you please provide the pdf of electrical design data , where you have written the sizes

Good work

Time 06:17 where this 1.4, 1.9 and 1.5 came from ?

I have sent an email to the given email address. till now , no response.

Is there a certificate awarded?

how do I get this course?

Thanks a lot for making a video of full knowledge, easy explaination, simple method.. it helps us a lot to perform best in company and to face the interviews. Tons of thanks to you❤

really helpful amir need a small help is it possible to get in touch with you that will be your most kindness

bhk mean

I am an electrical student i learn AutoCAD electrical and what i learn still

bhai v is not same for both bulb buddy

apfc panel dont work ,when DG is on operation or otherwise only for transformer EB loads only apfc works..pls comments when utility eb power failed & DG is on & powering condition ...apfc works or not

Well explained sir but want Telugu language

Well explained sir

Good Information sir

Sir give a link for , workout screen calculation...give a new video also sir

can somebody explain me that why are we multiplying the no of cores with the diameter to find the final diameter of cable??

2 incomer is coming from feeder. One for power. One for lights. Why?. Even lights can be connected to the single incomer

Good. Man.

Hi how to get this course

😍

❤

Informative..! Which notepad are you using..?

Sir can you please tell me why are we multiplying KW with Ampere for Circuit breaker sizing?can you please explain the formula or logic behind this ......

At 11:00 how did you get those MCCB values? Why is it almost doubled when you already multiplied them by 2?

It would be great to explain this slowly. Kind of confusing and some details were not explained properly. Why did you use 400A in 9:52?

Thanks brother..it's a very helpful video.❤

Please i want your eamil please

Great, haven't found any video on any platform like this. Glad if add cable sizing calculation grounding and lightning protection system.

Sir can you share the notes??

1 KVA = 1.9 anybody explain please in my calculation its is 1.39 something

Thanks for sharing

Informative

very nice Explanation sir thank you so much sir
