Passing Permanence: Reversible Building Practices in the U.S.

M.ARCH Thesis

The construction and demolition industries generate abhorrent amounts of waste through the inefficient generation and unplanned removal of permanently intentioned buildings that cannot last forever. Current strategies of material construction often consume, permanently alter, or degrade materials being used, resulting in the inability to wholly reuse valuable building components. As a result, existing unused structures will often become waste, or require resource intensive recycling or remanufacturing to salvage portions of material (USEPA 2018).

Buildings are not permanent. The current lack of life-cycle design and expectation for buildings to last indefinitely leads to a loss of “technical nutrient” potential (Braungart 2002). The reduction of waste, the continued reuse of materials and designing for component longevity can achieve a fundamental level of sustainability, as the concept of waste is antithetical to ability to maintain a process over time. To recapture the potential of a building and remove the ecologically harmful effects of permanence that occur after the building is no longer needed, the production, construction, use and demolition of architecture should ‘leave minimal trace’ on its building materials and site.

A current lack of reversible and circular practice in the US exists due to many existing social, cultural and economic factors. The focus on tradition, risk aversion, and bountiful space for new development allows the country to remain stagnant and reliant on existing building methodologies without the push for change. Initial reversible architecture located in the US will not be made out of newly developed components, but primarily of existing standardized materials joined in newly reversible methods.

Architecture should not be destructive. An architecture that leaves minimal trace does not have to employ highly engineered componentry and new modular solutions that restrict design outcomes, but rather can modify existing techniques and tectonic understandings to remove wasteful practices that intentionally degrade or destroy material resources. Minimal trace architecture simultaneously upholds the health of its materiality through the redefinition of connection types while supporting its site and larger context through the removal of systemic inefficiencies and unnecessary permanently-intended change.

Use Your Cell Phone as a Document Camera in Zoom

  • What you will need to have and do
  • Download the mobile Zoom app (either App Store or Google Play)
  • Have your phone plugged in
  • Set up video stand phone holder

From Computer

Log in and start your Zoom session with participants

From Phone

  • Start the Zoom session on your phone app (suggest setting your phone to “Do not disturb” since your phone screen will be seen in Zoom)
  • Type in the Meeting ID and Join
  • Do not use phone audio option to avoid feedback
  • Select “share content” and “screen” to share your cell phone’s screen in your Zoom session
  • Select “start broadcast” from Zoom app. The home screen of your cell phone is now being shared with your participants.

To use your cell phone as a makeshift document camera

  • Open (swipe to switch apps) and select the camera app on your phone
  • Start in photo mode and aim the camera at whatever materials you would like to share
  • This is where you will have to position what you want to share to get the best view – but you will see ‘how you are doing’ in the main Zoom session.
