Family Focused Dense Development | Check-In #4

Over the last week I have completed the structural design and made some changes to the building to improve daylighting.  On the structural side I have implemented a timber structural system with concrete footers and slab.  The structural elements will be exposedto the interior creating an industrial loft feel that is perfect for young families looking for a more stylish alternative to suburban track housing.  

I have also improved the daylighting system by stepping back the appartments on the south side of the atrium.  While this required significant design work, it also significantly improves the usefulness of the atrium and the daylighting to the apartments on the north end.  

The A360 link shows the structural design.  The preview images show the Revit Structural Model and the Robot Structural Analysis tool.  The Robot tool was used to analyze the north portion of the structure to size columns and beams for the entire structure.

Final Design Entry - Jasper Ridge Living Lab

CEE220B | ROMMY JOYCE

Living Lab

This is the final BIM design of my Jasper Ridge Living Lab.  When I started this project, I created these shapes by using Fibonacci spirals, which were overlapped in order to create organic forms to promote harmony between the building and the surroundings.  The entire building tries to showcase systems used to improve natural lighting and ventilation.  For instance, the stairs in the main building promote stack ventilation.  Another example are the shading features used in the building such as overhangs, light shelves, fins, trellis, etc.  Also, some parts of the buildings are earth sheltered to reduce heat loss.  To improve daylight the rooms that are earth sheltered, skylights and light wells were also used.  Below you can find my final design in A360 and here are some renderings:

Final Design Journal

Final Design Journal

Well…my last design journal can dated back to floor plan… So in this one, I would try to cover all the design path of my project.

Floor Plan:

In my first floor plan, the café was in the west part of the building, and one of the conference room was in the east part. But after the first live check in, I followed Glenn’s advice that my functional zoning should be clearer. So in my final floor plan, the café was moved to the southeast corner of the building, and both the two conference rooms are now in the west wing.

Designing Features:

  1. Suspended Corridor

This is the suggestion from Glenn that I love most. In the initial design, if the visitors want to move to the auditorium from the class room, they have to go downstairs, cross the yard and then go upstairs again, which is quite inconvenient. What I have done is to add a U-shaped suspended corridor that extends the second floor into the center. For now, people have a much shorter path from west to east. Moreover, as the corridor goes in front of the large glass mass in the center of the exhibition part, it provides the visitors a great view of the whole building as well as the landscape in front of it.

  1. Slope Roof

In the first journal, I mentioned that I will use the slope roof to collect rain water and provide proper angle for solar panels. But now I have a new idea. Since natural ventilation and daylighting is quite popular in the energy efficient buildings, why can’t we make the room exposed to the outdoor environment directly? With such a concern, I removed the ceiling of the second floor, and made the roof operable. So if the outdoor weather condition is pretty good for natural ventilation, the roof can be opened to let in outdoor air, and get some daylight. When the outdoor environment gets tough, the roof will be closed and mechanical system will be turned on. Also, by left the roof over the building body, a greater visual impact can be achieved.

  1. Surface Material

The surface material is wood texture. Since the building is located in Stanford, it has to fit in the surround building style. Wood surface would add more classical visual effect to the building.

Energy Saving Strategies:

  1. Roof

The picture below shows the light analysis of the two classrooms with operable roofs. Compared to the middle part where the operable roof is not installed, light is more evenly distributed, and only small part of areas would get direct solar beam.

  1. Water Floor

Thermal mass is widely used in “green buildings” to the solar energy during the daytime and avoid overheating. In my building, since I already have a large pond of water, I want it to be more than just landscape. In the reception areas, I used glass floor over a layer of gravels. In between, the water get pumped through to act as thermal mass. Then the water will be collected in front of the building to form another waterscape.

  1. Shadings

Solar shade are employed in different forms to avoid direct solar radiation.

  1. Solar Panel

Solar panels are install on the top of the roofs. Since the roofs are movable, the energy generation can be guaranteed by always having a proper angle. I did not do precise calculation of how much solar panels I need, but based on the energy analysis of Revit, the potential energy generation is larger than the energy in need, which means that the building can be net zero energy.

Energy Performance

I tried to simulate the building’s energy performance. Although the energy in net zero in total, the Energy Utility Intensity (EUI) is 44 kBtu/sf/yr, which is unacceptable for an energy efficient building. I made a lot of attempt to reduce EUI, but no matter how large the R-value I used, the simulation result never change.   The thing happens in lighting analysis. The “bug” is every likely due to my “tricky” roof. In the Revit model, the roof is in open status, which is quite confusing to the software. I got warned a couple of time that an effective roof is not existing. So after a series of adjustment, I personally believe that my building is quite energy efficient, or can be more efficient.

Structural Design

I did not spend a lot of time in structural design, because I seldom know anything about structural design. The design is only based on common sense…

HVAC

The HVAC system is tricky in that I do not have ceiling in the second floor, and I do not want to have ducts blocking the light. After discussing with Glenn, I decided to supply the air from sidewall, and return the air in the areas that do not have operable roofs.  Another difficulties of the design is to make proper connection within very limited space. I spent quite a lot of time in arranging duct path and the system is now twisted together. I have not got time for other mechanical systems…

One note though, for some reason, the grids on my structural file are no longer aligned to the structure. When I tried to re-align them, my model went from this

to this

Tracy6b

I wasn’t able to figure out why it’s doing this, so I left them unaligned.

Anyways, thanks everyone for a great quarter!

Design Journal 7 - Final Project

CEE 220B | Tyler Scharar

My BIM design for a Stanford Sustainability Center grew and adapted throughout the quarter.  What started as a demostration of a multitude of energy-conscious design decisions evolved to meet the expanding and iterative needs of space planning, structural solvency, and mechanical system operations.  The initial concept and final design are below.

    

The final design stays true to its initial inspirations, providing long, narrow, open spaces that take full advantage of natural sunlight, solar passive heating, and naural ventilation.  The lofted ceilings enable these spaces to not have a confining feel.

Visitors are funneled towards and attracted to the lobby, where they can experience the visible grey-water loop that incorporates a 3-story water wall and water fall.  Access through the remainder of the builiding is then possible only by experiencing the living/learning center: outdoor (i.e. roof) and indoor (i..e walkable exhibition spaces).

   

North and South wings hold seminar and conference rooms, offices, and children learning areas with vaulted beam ceilings and ample natural light.  A building "core" near the lobby and in each N/S wing allows a hub of transit/egress, communication, and mechanical systems in each wing, much as a vertical builidng may do per floor.

Water is efficiently used throughout the building.  Potable water (after use) and rain water is funneled into the grey water loop.  This system may be heated via the sun (i..e water wall) or a ground source heat pump to provide efficient water reuse to landscaping, radiant floors, and restrooms.  Throughout the building, this efficient water reuse system is visibly highlighted.

The biggest challenge was accurately assessing structural sufficiency of complex members via Autodesk Robot add-in.  The correct system had to be isolated and then the correct loads applied at the right locations.  Also, utilizing 3 different linked projects (architectural, structural, and mechanical) is challenging even with one designer.  This coordination and sharing of model components would be extremely challenging with several model conlicts if different teams were responsible for each part of the design.  I look foward to applying these lessons learned, as well as innumerable others regarding architectural trade-offs, civil engineering, and modeling.

Design Journal 5 - Structure

CEE 220B | Tracy

Tracy5a

Tracy5b

Tracy5c

Tracy5d

Since I’m not too familiar with how concrete structures work, I went with a steel structure for the building. Most of the structure will be steel, and there would be shear walls around the stairwell, mechanical shaft, and elevator.

I modeled the entire building as two separate buildings, as seen above. Since my building shape is pretty simple, and most walls are aligned one on top of the other, it wasn’t too hard for me to model — creating the grids and members were pretty straightforward, and I could pretty much copy-paste the members.

Left Wing:

The section has an overhang of 5-ft on the southern and western end (the bottom and left of the third picture). I did this because these sides are primarily glazing and I didn’t want columns to be sticking around near the edge.

Right Wing:

The right section’s going to be the exhibition space and I’d prefer to have a large open space here. Initially, I had a column that goes in the middle of the exhibition area that I was planning to cover with a giant wall. I did this so the span of the beams wouldn’t be too long. But after talking to Glenn, we changed the beams to trusses so I could get rid of the column in the center of the room. For some reason, the members around the center of the truss didn't show up on the model.

Note: I’m still not too sure how deep foundations should go — I’ll go ask Glenn about this and see what he thinks.

Design Journal 3 and 4 - Building Envelope and Architectural Features

CEE 220B | Tracy

This is what I have so far in terms of architecture. 

Tracy3a

The floors are made of concrete. I wanted the floors to be thicker to emphasize the ‘folded concrete’ look. I have all the floors as 1’ thick concrete right now. I have yet to specify floor finishes for the different rooms — I’ll do that next. 

In case anyone was wondering, the right wing of the building will be at ground level — it’s not going to be cantilevered out like the picture. Also, the first floor will be partially underground.

I have three primary wall materials: wood siding, curtain wall, and concrete. The wood siding would go around the first floor and the exhibition spaces — I’ll include some windows later on. Also, since curtain wall goes around some of the more private spaces (conference rooms, offices, etc), they will be equipped with cellular shades of sorts.

I tried to align rooms on the different floors as much as possible in hopes of making the structure a lot more straightforward. 

 

Southern Face

Tracy3b

The southern side of the building will the the side facing the lake, so this face will be primarily curtain wall to take advantage of the view, as well as to maximize daylighting. Floor slabs from the upper floors will overhang a little bit to offer some shading. 

The door on the first floor will allow for direct access to the lake from the main section of the building. However, there won’t be any entrances or exits around the exhibition space.

The door on the second floor will open up to a terrace, although I haven’t added some sort of barrier/railing around it.

 

Western Face

Tracy3c

The main entrance to the building will be on the second floor, and opens up directly to the lobby.

The third floor will be covered in concrete wall, with the exception of the back corner, which would be the play area.

 

Northern Face

Tracy3d

On the northern side of the building, the 1st floor would be completely underground. The only point of entrance on this side would then be from the stairs area on the 2nd floor. 

This side of of the building will be primarily concrete since this side of the building will be where the elevator and restrooms are.

 

Eastern Face

Design Journal 2 - Building Form and Overall Layout

CEE 220B | Tracy

This is my preliminary design:

Tracy2a

Tracy2b

Tracy2c

The ‘front’ of the building will be facing the south, and will overlook the lake — naturally, this side would have lots of window. 

LAYOUT

Left Wing

Functions of each floor are listed in the diagram above.

Stairwell, elevator and restrooms will be at the northern side of the building and will be at the same position in all four floors.

1st Floor (Green) will be partially underground and the 2nd Floor (Purple) will be at ground level. 

Right Wing

The first two floors of the right wing would be exhibition spaces. The two levels will be connected  by a flight of stairs located at the north-eastern corner of the area. 

Top floor of the right wing will be a roof garden. 

First, I created a large masses for each floor (see above). The total floor area of these masses ended up at about 15,000 SF, give or take.  Then I went on to create separate masses for each room and color-coded them to distinguish between the different functions. Finally, I tried to make sure that all the rooms fit within the large mass.

Below are the room masses and my floor plan.

Design Journal - Entry 7

Evening, everyone!

Finished up my mechanical systems since the last check in. Glenn was certainly right when it came to Revit and it's auto-routing features. I think I spent more time trying to figure out what revit was trying to do than actually laying out my duct. All of my mechanical systems are shown in the cover photo, which appear pretty clean right now! (And for those of you who will see my final presentation, we'll see why in reality they aren't as clean as they look.)

The first picture below shows the exhaust system. I started here because I figured it'd be the easiest to do, due to the fact that the only rooms needing exhaust were the restrooms. Furthermore, all the restrooms are in the same location floor-to-floor, so I could copy/paste the majority of my layout. The complication was in attaching a riser to the actual exhaust fan, but in the end some section views and alignment got it sorted out. 

Next I moved on to the rest of the HVAC. The idea I have is that each floor has its own air handler, which is located next to the elevator shaft. I didn't get the chance to show it in as much detail as I would have liked, but the idea is to have outdoor air intake louvers in the mechanical room that would be ducted to the air handler so they could supply fresh air to the spaces. 

The final step was the plumbing. This I think I had the most difficulties with. If I had to do it again, I would have made a larger wall cavity between the back to back plumbing fixtures to give some room for forgiveness. 

 

Finally, I've put my files up on Autodesk360 and shared a link!

Design Journal 1 - Ideas

CEE 220B | Tracy

I've had difficulties posting my entries in the past, so here we go...

 

Some of my inspirations are:

Natural History Museum of Utah 

The museum features one of the largest solar panel installation in the state — more than 25% of the energy needed to power the building are produced by PV panels on-site. Other sustainability features for the building include extensive use of recycled materials for construction and having large rainwater collection systems to irrigate the site.

Tracy 220B 1A NatlHistoryMuseumOfUtah

California Academy of Sciences 

The CA Academy of Sciences also adopted a myriad of techniques to reduce energy and water usage. To reduce energy usage for heating and cooling, the building is equipped with heat recovery systems to capture heat produced by HVAC equipments, radiant floor heating, as well as skylights that can open to remove warm air, among others. Also, efforts to minimize use of artificial light include having floor-to-ceiling window to maximize natural daylighting, and installing photosensors to dim artificial lights depending on the amount of daylight penetration.

Tracy 220B 1B CAAcademyOfScience

Museum of Liverpool 

The museum features state-of-the-art technologies to reduce carbon footprint, such as adopting a ‘trigeneration’ technology for highly efficient heating, cooling, and electricity generation. This technology also reduces carbon emissions by 884 tonnes annually — “ equivalent to the environmental benefit of taking  295 cars off the road”.

Tracy 220B 1B MuseumOfLiverpool

Main sustainable design features:

maximize daylighting: south-facing windows, skylights

low-e, double-glazed windows, with sunshades/fins

PV transparent glass

using concrete — thermal mass

greywater reuse, rainwater collection and reuse

green roof

efficient HVAC systems

As for the look of the building, I’m going for a more minimalist design, similar to modern Scandinavian architecture. A few things I’d like to do are:

using basic shapes, clean lines, and solid colors to achieve a simple and clean design

having lots of large-pane windows to maximize daylighting and and view

using light colors for the exterior and interior

extended roof panes — doubles as a canopy for shading too

Some examples of buildings I like are:  Tracy 220B 1D Example

Design Journal - Entry 6

CEE220B | Charles White

Hello!

After Glenn and I met last time I had my work cut out for me, but I’ve finally gotten my structure to the point that I’m done working it. The main feature, structurally, is the large cantilevers that will support the exhibition space hovering out over the slope. 

On the back side of the building I’ve used walls that are intended to handle both static and shear loads. I used these walls because they’re the most consistent for each floor, as they surround the stair cases, restrooms, and mechanical and elevator spaces. The walls that reside underground or act as a berm I’ve also made structural, as they need to be able to support the earth above them and hold the earth back from caving in the sides. I also had fun playing with the different sloped roof. Figuring out the reference plane was certainly interesting.

Since then I’ve been trying to bring my architectural model up to speed by putting the walls where they’re supposed to be, making my wall types the kind that I want, and adding architectural components to make the space look like it’s actually usable.

Design Journal Seven (Part 2)

CEE 220B | DIANNA BARBA

When analyzing a portion of my structure to size the members, I ended up analyzing the pedestrian walkway in my building since that was one of the features I liked the most in my building and I thought it would have a large load because it is kind of like a hallway. I also wanted to see how my braces, which were incorporated for both lateral loads and architectural effect, would perform against the loads imposed on it. I ended up putting 100 psf for the live load, even though online I saw that it should be 85 psf for a pedestrian walkway. I wanted to make sure my walkway was pretty strong just in case anything occurred. I put a structural floor on just that section and added a hosted area load of 100 psf. I also added the boundary conditions (fixed at each column to reduce deflections). I then selected only the parts I wanted to analyze and exported it to Robot Structural. On Robot Structural, I realized that all of my braces caused my walkway to be unstable. This made sense because the members are too small to sustain the load imposed on it and I had just added any random members. When choosing my members, I went ahead and changed them multiple times to find a member that had the lowest weight and worked. I prioritized reducing the weight of the member over member depth since member weight can have significant effects on the building both structurally and cost-wise, though cost is not a factor in our project. And since my structural members are supposed to be celebrated in my building, I had no problem in making them deeper and more pronounced. My initial members can be seen below, as well as the designation of unstable members versus ok members.

BarbaRobot5

BarbaRobot4

I not only prioritized weight reduction for the braces in my building, but I also went through and changed the other members in my building to do the same thing. I did not want my members to be too over-designed because that is unnecessary for a building. The capacity meeting the demand fairly closely is all that is needed. What I struggled with was actually using load combinations in Robot Structural. I went ahead and tried adding both the dead load and the live load in the top drop down menu, but when doing the analysis and steel member design, as seen below,it seems like only case 2LL1 was used, or governed. However, I want 1.2*D +1.6*L to be used to size my members, and I am not sure how Robot Structural works with this. It says it is analyzing according to the code, however the size of my members (they seem too small) makes me doubt this as well. Since I had spent a lot of time trying to figure out what was wrong, I figured that I should just go with what I have. From there, I imported my new members into Revit so that my structure can be updated with my new members.

Final members imported back into Revit from Robot Structural:

Design Journal 6 - (in person) Lighting/Structural Analysis

CEE 220B | Tyler Scharar

Check-in was completed in person.  This is just an update to document progress.

STRUCTURAL

The structural systems are essentially complete.  I've had some difficulty with the linked projects (structural and architectural).  Basement concrete walls are structural walls, and I've copied/monitored them to the architectural model, so that the rooms in the architectural model have boundaries.  When copied, the walls turn into curtain walls (not sure why), so I have to manually revert the copied walls back to match the structural walls (concrete retaining wall).

I have made initial attempts to analyze a cantilever patio deck for structural soundness.  This elevated platform is made of structural steel.

NATURAL LIGHTING

In the basement walls, exposed upper portion of the wall has windows in them.  During lighting analysis, the program does not recognize these windows at all, causing the entire basement to have zero natural light (which is obviously incorrect).  I will need to find and correct the disconnect between these walls in the linked models.  Other spaces seem to have sufficient natural light.

UPDATE 5/31: Unlinking the structural model allows the structural walls copied to the Architectural project (with windows added) to accurately reflect results of a Natural Lighting analysis.  Some window types do not let any light in (i.e. transom), so testing window types in a simple, new project allows quick analysis and testing of various windows.

GRAND ENTRANCE

We discussed the approach from the parking lot to the main lobby.  Adjacent features will be subdued to focus attention on the main entrance and stairway.  The elevator shaft provides a nice distinct feature that helps to focus this attention, standing out from its surroundings by use of its protruding shape and different building materials.
