Building managers got the hint and within a year blinds were installed. Morphosis has used the double-skin system since then. Other American architects pursuing large-scale sustainability are more likely to use conventional sunshades — or, if their client is willing to spend the extra money, glass developed the past few years that repels heat all on its own.
Along with the push for sustainability came the idea that the federal workplace could be revolutionized. The atriums are almost always vacant, if several visits to the tower during the past few weeks are any indication. The skygarden is filled with employees at lunch, but empty at other times. Ciprazo loves the complex, despite her disappointment in the plaza. But she also says that it has taught her the limits of thinking that architecture can inspire people to alter their daily lives.
Because of that, you are bound to fall short sometimes. Ultimately, in terms of lasting impact, the real value of the San Francisco Federal Building may have been as a rhetorical tool.
The design argued that eye-catching architecture can be coupled with environmental values. The plaza, for all its problems, suggests that government and diverse communities can co-exist. Large-scale urban buildings often debut with high hopes. This one was no exception. The real test comes as they settle into the city. And as the mixed results at Seventh and Mission streets show, that is no easy task. It is the first naturally ventilated office building on the west coast since the advent of air conditioning.
Upon reading the descriptions above and seeing the building on pictures. I recall our peer lecture last Thursday about Thom Mayne.
I listen carefully on what is his philosophy and also his working concepts. It is something that will be always there and no matter what you do you need to respect it. Also, I recall about his working concept. So, this are the things that I learned from our lecture last Thursday. He used juxtaposing gray concrete walls with custom zig-zagged 9 walls wood.
For the design response of the people around it. Some may think that this an excellent building it fits perfectly for this urbanized city. Here is a responses or I should say a criticized statement towards the building. Workers seek to relieve the heat by opening windows, which not only sends papers flying, but, depending on their proximity to the opening, makes creating a stable temperature for all workers near impossible… some employees must use umbrellas to keep the sun out of their cubicles.
By just looking at the photographs of the building, for me, it seems like Mayne did a technological approach in designing this structure. He displayed honesty in the building. He showed the gray concrete , the glass and also the steel railings. The gray concrete when looked from a far showed vertical and horizontal patterns that looked like small cubes perched on the structure.
The slightly distortion of the supports on the lower side of the structure made a dramatic effect in the sunlight when it is hit. The light was emphasizing some of the edges of the building. Also, his philosophy was there. He blended in to the culture of this urban city. Architecture also must not be complicated. It needs to be human friendly. His concepts is also in his building. I mean, it may be simple at least it is very useful to a lot of people. Also it enhanced the life of the people who use it.
Also, the structure helps the environment too! San Francisco is generally dry during summer and moist cool winters. The city is surrounded by three bodies of water which are all cold Pacific water from the ocean currents.
This creates a very constant temperature swing throughout the year creating a year round climate that has little variation.
The large lobby space utilizes an unusually tall angled facade and skylight to bring in light while evenly diffusing light with fluorescent lighting where needed.
The higher floors have two very different facades that are both designed to bring in as much light as possible, while blocking excessive heat gains from direct sun. The southern side uses hundreds of vertical glass sunshades to block the direct sun from the morning, while the northern side uses a permeable metal panel system to shade the interior.
The concrete ceilings bottom left are designed to use less concrete than a solid slab while giving more curtain wall exposure for more day light. Prevailing winds coming from the northwest, penetrating the facade of the building and channeling the warm air out of the building through the porch landings that protrude out every three floors.
Cross Ventilation The winds circulation pattern through three floors of connected office spaces and conference rooms. The federal building is almost completely covered by a draped metal facade that shades the building from sun and rain.
The enclosed curtain walled building is incased in either a perforated metal panel system or a structural system that holds up the vertical sunshades. This unitized system was fabricated off site, then transported to the site and hung on the buildings concrete and steel structural system. The four diagrams are showing the different sections of the perforated rain screen that covers the majority of the building.
Rain Screen Enclosure The detail shows the complexity of these systems. Their sole purpose is to insulate and separate inside from outside.
