During Week 4 the group presented and shared their research. We created a collaborative document with Google Docs in order to effectively categorize our research and outline our essay. The document allowed all the research collected to be categorized by subject. This week we received dozens files of the architectural and building system diagrams. The drawings available were extensive; there were plans of the building's HVAC, structural, and mechanical systems. We lowered the number to about four that are relevant to our project, including the roof layout, stairs and elevators, and plumbing system. A basic model of Hagerty Library was found to be available on Google Sketchup. A Revitt model of the library was started this week.
In line with thinking about building systems, the addition of a green roof can significantly impact the microclimate of the building. It is essentially adding an additional layer of insulation to the roof. It is estimated that the green roof influences the temperature of the building by up to a 25 degrees Celsius temperature difference in a regularly irrigated five story building. Adding many living roofs to a city could help mitigate the urban heat island effect, by decreasing the amount of heated surfaces. An urban heat island is a urban area, significantly warmer than its surroundings. When comparing the area of a green roof to that of a gravel roof, the temperature difference can be as radical as 30 degrees Celsius.
