Hey Everyone!
As of tonight, I have graded all of your Revit Assignments and have a few comments to make. First, there was a lot less information missing on this assignment, so it shows you guys have read the rubric and attended to that specifically. So thanks for that! There were a couple of common things that were missed on this assignment. The first is that a lot of you had floor plans without measurements on them. It says on the assignment page to provide a measurement, so I can check to see if the wall length requirement was met. I only took off a point for this, since I could generally tell that most of the buildings were long enough. Additionally, if you were among the first few students to submit your assignment and checked your grades last night, I had taken off 2 points for missing a shaded view in perspective. To clarify, a "shaded view" in Revit is not a perspective with shadows, it is actually a simplified view of the building in color. After discussing with Professor Mitchell, I have given any points taken for this back, since you all did provide a rendering, which was the most important part. Just keep that in mind, since "Shaded" and "Realistic" views provide nice renderings for presentations (you can make good use of this in AE391). To toggle the view, go to the bottom ribbon in Revit and find the Cube picture, which allows you to switch between wireframe, shaded, realistic, and hidden line views. The only other major mistake was not including "Family Information" on the door schedule. This is an option when selecting what to include in the schedule, and it information about the component itself. Overall, I was really impressed with some of your models. A lot of them were better than anything I had seen an AE student in my class produce.
If you wish to resubmit your Revit, please email me your sheet in PDF and the write up to amm543@drexel.edu. With your email, you should include a few sentences on what you have addressed in your resubmission. These will be due next Thursday, October 6th at midnight.
Hope you all have a fantastic week! :)

Assignment 1 Grades and Common Mistakes
Hi Everyone!
I will be using this blog to post common mistakes on each of the assignments throughout the quarter. I have graded all of the first assignments and have noticed a few common problems. I think there was a lot of confusion with the rubric. In order to get full credit, you must complete all requirements in the "Average" column and the "Average +" column. This was the biggest source of errors. The best way to prevent lost points is to explicitly address all the rubric concerns i.e. "The most difficult aspects of this course are..." I read all of your text and look for requirements that were addressed, but I am less likely to accidentally gloss over something if it is called out in this way. If I have taken off points for something that you think you addressed, please bring it to my attention and I would be happy to look at it again! Also, all of your images in these assignments should have captions that describe why you have included them. There weren't any points associated with it, but please be sure to cite all your sources. I tried to be pretty lenient on the use of web capabilities since this was a lot of student's first website, but please make sure you proofread your work. Spelling and grammar errors will result in lost points. If English is not your first language, have someone read over your website before you submit. If anything is unclear, it is best to bring it to our attention. That way you can address all the requirements accurately, and we can update the assignment requirements so they don't confuse future students.
If you decide to resubmit this assignment, you have one week from today. Resubmissions for 2/3 of the points lost are due on September 29th at midnight. Please email them to me at amm543@drexel.edu and DESCRIBE WHAT YOU HAVE CHANGED. As always, if you have any questions, feel free to email me or come find me in the Cadlab!
Have a Good Week Everyone!

URL for RMI Video on High Performance Design
Question:
I know we have to comment on the video we watched in class for assignment 1 but the link that is provided in the overview is not the same video we watched. Is there another location for this link?Response:
Hmm - Here's the YouTube address - it's in the "General Resources" section of the website. I guess RMI changed the link.

Building Systems – Rules of Thumb
Site
- Site - to Consider
- Zoning
- Setback
- Parking Requirements
- Height limitations
- Relationship to other buildings
- Shading issues
- More in other countries than US at the moment
Architecture
- SF/ Person - 200-400
- Circulation % of building 15%-50%
- Exiting requirements
- 2 separate exit paths (protected) with 20' of exit from room or suite
- Floor to Floor
- 9' in apartments/hotels
- 12-14+ in commercial
Structure
- Depth of Beam in 1/12 of Length
- Ie. Depth in inches = Length in Ft
- This is conservative - often 2/3 to 3/4 of this
- Studio Companion is great Resource
- Design Loads
- Live Loads
- Gravity
- 40#/SF residential
- 80-100#/SF commercial
- 250#/SF+ for storage and other special conditions
- Snow - up to 30#/SF
- Dead Loads
- Self-weight
- Lateral Loads
- Live
- Wind - 90mph ~ 28#/SF
- Seismic
- Blast
HVAC
- Duct velocity - 800FPM to 3,000FPM
- Chiller Sizing - 200-400 SF/Ton
- Ventilations - 10-40 CFM/person - depending on activity
- Equest is great resource for first approximation
- Design Temperatures
- Indoor
- 72-78 DegF depending on age, season, culture
- Outdoor
- 14 DegF Winter
- 90 DegF Summer
Electrical
- Typical feeds (in Philadelphia) 13.2KV 3-phase
- Typical in-Bldg voltages
- 480/277 - motors and lights
- 208/120 - Convenience, portable appliances, some lights
- Emergency System
- Range from corridor lights only (2fc -> battery packs)
- 100% backup
- Duplicate feeds from separate substations
- Emergency Generator
- Depends on purpose of building, client desires
- Increasingly will see tied to alternative energy &/or electrical storage (batteries mostly)
Other Systems – Non-Exhaustive list
- Geotech
- Fire Protection
- Stormwater
- Lighting
- Circulation
- Transportation
- Plumbing
- Security
- Telecom
