Thanks for your comment. The table is something I created in excel and took a screen shot to explain the internal loads. Unfortunately it is not part of the program. Every home builder has their own tables and requirement for internal loads. However most of them refer to Manual J guidelines.
I know I'm late but I'm learning Wrightsoft right now and I appreciate these videos, thank you for your work. I have a question how do you get your internal loads? Is it from the customer or was it in the program?
Thanks for your kind comment! For internal loads you have different options: 1. If it is a new construction the home builder usually provides their own requirements. Among them are the heat loads 2. If you don’t have the home builder requirements you can rely on what Manual J recommends or wrightsoft (Which is based on Manual J anyway) 3. You can take my internal loads table that summarizes the heat loads and they are taken from Manual J. This is the easiest way. Usually when I don’t have that information I just use the table I show in the video.
Thanks for your kind comment! To reference the Loads it is a great resource to check on the RIGHT-J WORKSHEET in wrightsoft. This is pretty much the ACCA Manual J Worksheet which doesn't account for lights in residential. In commercial projects (ACCA Manual N), lighting is very important measured in W/SF depending on the location. Refer for example to the Table C405.3.2.1 from the IECC-2018 to find LPD values (lighting power density) codes.iccsafe.org/s/IECC2018P5/chapter-4-ce-commercial-energy-efficiency/IECC2018P5-CE-Ch04-SecC405.3.2 Hope this helps.
Awesome video !! A thank you from Vietnam
Thanks for your kind words!!
I didn't see how you opened the internal loads table (Black colored). I check the 3rd video and didn't see it there... Could you please explain?

@@hvaceasymath Does this mean that light loads just don't really matter in residential loads mostly?
Yup, not so much. Mainly in semi commercial and definitely in commercial building.
i dont understand where you are getting the loads for the chart "internal Loads.jpg"? 683 btu's but where do i get that information?
nevermind i see this question has been asked.
No worries. Thanks you 👍
would you be opposed to me sending you my project? im pretty sure i have some problems.
I am currently out of the USA, but I’ll be back by next week. We can chat through my email hvaceasymath@gmail.com
