-How would you feel about being an occupant in the San Francisco after reading the article?


I think I would have a great level of respect and appreciation for the building to be in it now. I would have been especially interested if I had lived in close proximity to the building and aware of what was taking place during the construction. As such a large focus is currently placed on sustainable and green design, this building bucks that trend. I do not necessarily think this is a bad thing, and would be curious to see the metrics of how ‘bad for the environment’ this renovation really was, considering attention was paid solely to the accuracy and honesty of the materials vs. a green objective.


– What types of lighting was discussed? How could these fixtures be used for Chatham County?


Basically every type of lighting, on the market that is currently used in the building industry today was discussed. Fluorescent, LED, and daylighting were included, among others. I think we have the opportunity to use any all types of lighting in the City Hall design. My choices will be driven by how my concept fits with my application. I’m guessing I’ll be using a bit of every type, with an emphasis on playing up the day light.


– Is the Chatham County Courthouse appropriate for a dominant day-lighting system?


I would say a definite yes. While there are some very permanent structural restrictions with this design, especially on the first floor, they actually play into the favor or the daylight in the office spaces. The challenge of  day light entering the space will be the greatest in the navigational paths on the main level. For this reason specifically, I will be incorporating a central skylight to the space.


– What are the benefits of day lighting?


Proven benefits of day light within an office environment are many, and include positive effects on circadian rythyms, vitamin d intake among others. Clear lines of site will also play an important role on the user’s navigation of the building, way finding, and general level of comfort while in the building.


– Do codes matter for lighting design? Explain.


Yes, codes always matter for lighting design. There are specified limits for the minimum levels of light needed for specific spaces and tasks. That said, how much or how little, and how light is controlled is up to the discretion of the designer, and will very depending on personal opinion.


– Is lighting subjective or objective?


I would argue that lighting is subjective. Considering that it is proven that levels of lighting tested to be way less significant to a user’s mood in the space than did the proximity to windows. Based on the readings, and my personal experience, I believe that lighting levels can ultimately become a conditioned response.


– How does the info from the articles apply to the programming document?


The info for the articles will help with support the decisions made for the users needs in the programming document. As vision is the primary sense used by humans to understand the space their in, lighting plays a crucial role in our designs. Knowing more about lighting, and its influences, we will be able to make informed decisions.
