Week 9

This week was spent preparing for the presentation and making several revisions to the paper based on instructor feedback. The new prototype was also modified and assembled. At this point most of the work was just in wrapping up the final aspects of the design and paper and making sure that our presentation made sense. Not too much work was required other than practicing our sections of the speech and proofreading the paper.

Above are images of the simple prototype which was made to show the movement of the facade's pieces.

Week 8

This week the group concentrated on finalizing the prototype as well as correcting any problems in the final report and preparing for the final presentation. The draft of the final draft had at this point already been submitted, so the group worked to fix any errors or omissions which the grader had noticed. We also had a practice presentation in Week Nine, so at this point we had to put together our slideshow and decide who would talk about which sections. This week the group also concentrated on adding a more exact description of the design to the final report. This description will be added to the Project Overview and the Design Description tabs when complete. The design is still in concept stages, as the main focus of this project was in research, rather than development.

One problem encountered when building a prototype was that the size we tried to make was much too large. The prototype was very unwieldy and small errors in the angles of the arms meant that the points did not actually meet at the center. Because of this the group decided to make a smaller, easier to handle prototype which would look less impressive, but which would work better and be easier to make.

Week 7

Much of the time spent on week this week outside of class was focused on writing the rough draft of the final report. This included the developments mentioned up to this point as well as our purpose for the project, our finding on the various methods which exist which we have combined in order to make this new design and our predictions on what still needs to be done before the design can be finalized. Overviews of this information can be found under the "Information/Resources" tab.

At this point research regarding the light shelf aspect of the design was also done and added to the paper, though these benefits were now considered more a pleasant coincidence than a real goal for the design.

Research was also done regarding the improvements in morale and productivity which daylighting can achieve. In this research, which can be seen in our paper and found in the Information/Resources tab, we found that humans often experience better mood in daylight, due to our adaptation to its spectral distribution and its changes throughout the day. In one study of 13 schools, children taking a standardized test in more daylight worked up to 25% faster and scored up to 18% better than students with less daylight.

Week 6

The group finished designing a computer model of the "pods" of the THMF in SketchUp.The rough draft of the final design report was started and plans to begin construction of a prototype were drawn up; after it was realized that the group was falling behind in the production of a prototype, as seen above. The group also realized that more research needs to be done with respect to placing a double facade on a building, in retrospect to how efficient a double facade would be.

This week was mainly spent doing research, which can be found in the Information/Resources tab as well as in the papers linked to in that section. Further detail was added to the design ideas, which can be found in the Design Description tab.

Week 5

The group looked over the various simulations made. They also added in a model of the Amtrak Cira Center as the building to which the facade will be added. At this point the group was still considering a double layered glass facade, placing the flowers inside the "chimney" of the facade. This facade could then be used to help cool or heat the building through convection. At first they thought that the convection current between the two panes of glass would allow the façade to remain in a more "open" position in hotter conditions. The cooling effects of the convection would allow light to enter to building yet filter the heat of solar radiation. However, they later reconsidered and decided to place the pieces on the outside of this double-skin facade. Doing this would allow the design, now called the Transformative Heat Monitoring Facade (THMF) to monitor the heat, rather than the amount of light. The facade would close when the facade was too hot and allow the convection current to recover.

Here is another piece partly opened:

 This is another view of a section of the facade almost completely open.

This is an image of the facade pieces at various stages behind the outer layer of glass and affixed a certain distance from the existing windows, made before considering the benefits of monitoring heat instead of light.
