Summary of final journal entry:

Highlight local sustainability innovations
Key design features
1. Use of shipping containers
2. Use of natural daylighting

Big successes
1. I’m really proud of my architectural design.
2. I’m happy with the integration I achieved between the architectural and structural models.

Big challenges
1. HVAC system, had to correct and redo that a couple of times
2. A lack of confidence in modelling shipping containers and natural ventilation in Revit

Lessons learnt:
1. With Revit, anything is possible, it is a really powerful modelling tool. Don’t be afraid to find ways to hack through a problem if the conventional way is not working.
2. Its difficult to think big picture in the middle of modelling, its much easier to go back and do corrections.

Next steps:
1. Run clash detection
2. Model natural ventilation
3. Explore the use of butterfly roof design as used in the Namibian desert

Unique Features Explored
- Passive lighting
- Passive ventilation
- Reflective paint
- Masonry use

Big Successes
- Passive lighting of the second floor by use of skylights and light shelves
- Traditional Zimbabwe architectural look
- Minimal energy use
- Economic thermal properties

Big Challenges
- HVAC implementation. I would have increased my story height for easier implementation and sought help from Glenn sooner. But honestly why I couldn't size my HVAC system is still a mystery even after totally redrawing it multiple times but I finally got it to work!

Lessons Learned
- Use at least 12 ft story height
- Size duct segments one at a time or add a stem on main duct before attaching flex duct but be careful because when you add a flex duct to the stem, it adds an additional stem so you have to remove one of them (at least it did for me) before you size the entire duct line
- Don't be scared to experiment and explore cool options. I was definitely scared to mess with my roof, for example, to increase natural ventilation because I was afraid I'd totally screw it up. Similarly for a grey water system.
- Make sure you make room for all potential features, even if you don't end up implementing them (i.e. additional mechanical or plumbing room)
- Make use of recorded lectures

Honestly I wish I would have put more effort into the passive lighting of the first floor and natural ventilation through the roof. But overall I thought the project turned out well. I tried to keep the project realistic while still meeting class requirements because I'd like to submit my findings to Hippo Valley.

Thanks for a great class, Glenn!

Here is my building fly-thru:

Final Design Journal Entry

Key Design Features –
Atrium – The building’s most dramatic architectural feature is a three story atrium with a South facing glass wall.

Open Office plan – Most of the building’s office area is configured as open offices to provide maximum flexibility.

Cafeteria / Ceremonial Area – the first floor has a large multifunction open area that serves as a ceremonial area for the Headquarters staff and also a café.

Steel Structure – The building’s structure consists of a steel frame, designed to support gravity loads. Columns and beams consist of W12x24 steel members.
VAV Terminals – The building’s HVAC distribution system uses two rooftop AHU’s and a network of VAV terminals to provide heating, cooling and ventilation.


Daylighting – By using the Revit’s lighting analysis tools I was able to provide adequate daylighting for most of the building’s working areas. Revit also allowed me to determine which areas needed more lighting. The building’s North-South orientation helped with daylighting.

HVAC System – laying out ventilation, VAV terminals and AHU’s was easier than I anticipated (I thought it would be impossibly complicated!). Modeling air flows and heating and cooling loads within Revit was reasonably straightforward. Revit has the potential to be a very powerful tool for designing HVAC systems.

Structural analysis – The structural analysis portion of this design was beyond my abilities. Lacking a background in structural engineering and familiarity with Robot and eTabs made structural analysis very mysterious to me. It was valuable to see some of the software and techniques that are used, but I doubt I will ever attempt to do any structural analysis on my own!

More detail on HVAC system – If I had the time, I would have included some more detail and interesting features in the HVAC system. A radiant floor system, for instance, would have complemented the VAV distribution well. Also, I would have liked to spend more time optimizing the placement of diffusers and layout of the system.

Greywater system – One of the features I would like to have included (but didn’t have time for) was a greywater system.
Natural Ventilation – The building’s atrium would be ideal for a natural ventilation system. The glass curtain wall system could be designed with openings to catch the site’s South winds and louvers in the roof to allow air to exit.

Lessons Learned -

Elevator and stairway in central core – The building has a central core with an elevator, a mechanical room and a stairway. Consolidating all of these elements in a core in the center of the building made sense from a fire safety and building layout perspective. The central core wall is modeled as structural concrete which will provide the building with additional strength.

Building Integration – The project was integrated using BIM360 Glue. This seems like a pretty effective way to administer a project and perform clash detection. File management and administration for BIM360 seems to have a bit of a learning curve.

Design Journal 8

Traditional plumbing system. Wall mounted sinks, toilets, and urinals appropriately placed. All piping is copper with the following diameters:
Domestic System: 2" pipe ; Sanitary System: 4" pipe. All fixtures properly connected to the piping systems.

Plumbing for the bathroom can be seen in the image below. I had a problem copying the plumbing to the other restroom for unknown reasons.

Errors were found in my HVAC system. However, I have been unsuccessful at solving the problems and now the HVAC system looks worse than it originally did. Ducts will not size for unknown reasons and connections between the diffusers and ducts seem odd. I have become very frustrated and will look into the problem further this weekend.

Design Journal Entry 8
Mechanical Model:
I upgraded my architectural model, placing bathroom fixtures and a ceiling in it.
In the mechanical model, I added MEP fixtures and connected them to the sanitary, hot and cold water lines.
A sprinkler water system was created and routed such that it did not interfere with the skylights and openings for the stairways.

Further improvements to the model would include modelling the fixtures as low flow fixtures and time allowing, differentiating the systems such that the grey water is separated from the black water.

Design Journal Entry #8:

This design entry focused on plumbing fixtures

Domestic Hot and Cold Water Systems
-Main Trunk Lines and Branches
-1 ½ “ Copper Hot and Cold water distribution lines run through the “wet wall” between the men’s and women’s bathrooms on all three floors.
-Connections to Fixtures
-Copper branch lines connect all lavatories, toilets and urinals.

Sanitary Systems
-Main Trunk Lines and Branches
-A 4” sanitary line runs through the wet walls on all three building levels. The line has a ¼” / 1 ft slope.
-Connections to Fixtures
-The Sanitary line collects waste from all six bathrooms and directs to a vertical riser which exits the building and connects to the municipal sewer main.
