A2 - Generating Floor Plan Assumptions

Question:

I am finishing up Assignment 2 for AE 390, and haven't had any luck finding the first floor plan for xxxxxx. I know the rubric says to show the first floor plan, but would it be acceptable to show the floor plans for the other floors I found?

Response

I urge you to create a rough floor plan even if you don’t know the details.  You can start from an upper floor plan.  Particularly for office buildings you can guess that they will probably have:

• Lobby opening on at least one main street
• Loading/Service area
• Parking garage entry if there is a garage below
• Retail stores along a significant portion of the main streets
• Elevators – obtainable from upper floors
• Exit stairways – obtainable from upper floors

A2–Energy Flow

Question

In your suggested assumptions for assignment two you list energy flow for South and East/West facing surfaces. Are these for windows & translucent surfaces only or for the entire façade? Thanks for your help.

Response

Normally one would mean the entire surface area.  You may well want to calculate the flow for each surface type and then add them.

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

A1a–Revit Assignment Questions

Question 1

I am using the 2015 version of Revit Architecture. Will this be acceptable to upload when I am finished with my model or do I need to save it as an earlier version?

Response

Yes, you may upload any version of the Revit model.  For grading purposes the PDF and the word document are critical – the Revit model is primarily backup.

 

Question 2

Also for clarification, there is no website associated with this assignment correct?

Response

Correct – No website.
