DUPLICABLE CITY CENTER
STRUCTURAL ENGINEERING DETAILS

Details coming…

One Community is designing an open source and free-shared Duplicable City Center® to help model a redefinition of how people choose to live, save resources, and function as a revenue generator and starting point for DIY and replicable sustainable city construction. It will open source 15 different templates and function as a recreation center, large-scale dining hall, large-scale laundry facility, and alternative for visitors that might not (at first) be comfortable staying in the Earthbag Village or Straw Bale Village.

1.1. What is a Duplicable City Center?

Once complete, the Duplicable City Center will be the largest open source/DIY structure in the world. As part of One Community, it will be a diversely functional, ultra-eco-friendly (LEED Platinum Certifiable), space and resource saving community center designed to be replicated. It is meant to be (but doesn’t need to be) built as the central and/or starting point of any one of the seven (7) One Community sustainable village models. Its purpose is to support a redefinition of how people live by providing a space more beautiful than most people’s homes that replaces the need for individual kitchens, living rooms, laundry rooms, and other in-home recreation spaces. It is also purposed to function in conjunction with One Community’s open source nonprofit and for-profit business models as both a non-profit teacher/demonstration community, village, or city center and/or the central structure of an eco-tourism destination. To our knowledge, it will also be the first open source and DIY commercial building ever to be built.

1.2. Why Create an Open Source Duplicable City Center?

Building a duplicable city center is an opportunity for people to improve their way of living through investing resources in shared space. As part of One Community’s 4-phase global change strategy, we will demonstrate building a city center like this as providing five (5) primary benefits:

  1. It saves huge amounts of money and resources
  2. It builds Community and supports a sharing and cooperative mentality
  3. It is an excellent launch point for teacher/demonstration hubs to be built around the world
  4. It is an ultra-sustainable and modern option that will appeal to many people who might not otherwise consider joining the self-replicating teacher/demonstration community, village, and city movement. It is also brandable for people who want to make eco-tourism a revenue producing component of their off-grid strategy
  5. Increased affordability through our open source do-it-yourself plans and provides 15 templates for replicating all the components including complete DIY structure assembly, hydronic systems setup, the natural pool and eco hot tub, eco-laundry for 300+ people, eco-kitchen for 400+ people, DIY pallet furniture, climate battery design and implementation, advanced control and automation, sustainable energy infrastructure, LEED Platinum lighting design, LEED Platinum HVAC design, LEED Platinum materials selection and acquisition, and eco-tourism revenue generation for community construction and expansion using this structure and the other 7 villages models

In traditional society, each family home contains space for socializing with friends, preparing and eating meals, and doing laundry. We believe that we will save significant space and resources by providing shared access to a high-quality environment for these activities within our City Center instead. This, in accordance with our global change methodology, creates another path to the One Community global-change model spreading on its own. Here’s a video tour of the structure and why we think people will be happy for this alternative to traditional housing models:

Q: Why geodesic domes?

Geodesic domes were chosen for a broad diversity of reasons. First, we wanted a structure that could be purchased and shipped anywhere in the world, were uniquely attractive, and provided large open spaces that big groups of people would feel really comfortable in. Domes are beautiful, purchased as kits, and the curved walls and ceiling (in this case 35 feet or 10.7 meters high in the center) use approximately a third less surface area to enclose the same volume as a traditional box home. Geodesic domes also perform well as passively heated and cooled structures because the aerodynamics of the rounded walls encourage air to travel efficiently around inside the building. The geodesic design is also especially beneficial structurally in that the larger the building, the stronger the dome. The round structures also weather hurricanes and tornados significantly better than box structures.

Q: How does this structure fit into the global transformation and open source goals of One Community?

As this page states, the Duplicable City Center sets an example of how to save money and resources through cooperative and shared laundry, dining and food preparation, and recreation space for over 300 people. It will also produce significant revenue through its rental rooms. In addition to this, the Duplicable City Center is meant to provide a high-end and profitable option for people who either:

With our Highest Good of All philosophy being to provide something for everyone, the above three benefits of this structure specifically hold value for a higher-end and investment-focused demographic. As part of One Community’s global transformation methodology, we see this as an opportunity for corporations and other private investors to start sustainable and self-sufficient teacher/demonstration communities, villages, and cities with a traditional, contractor-buildable, and profitable building like this and then use our same community membership model to provide people with free housing or a potential revenue stream (see “Community Sponsored Business” example) in return for free labor to help build one of the 7 village models.

Investors save money and members have the potential to build themselves a house and/or a revenue stream in return for investing their time (no financial investment). On top of this, both investors and members are contributing to further spreading and sharing teacher/demonstration communities, villages, and cities.

Q: How do you expect to achieve near-100% passive cooling for this structure?

The Duplicable City Center has been designed to meet its cooling needs through exceptional venting combined with the 35-foot high dome ceilings, outstanding insulation (40+ R-value), window and structure positioning to maximize the benefits of property-specific wind patterns, and the ability to shade or cover all South-facing windows during the hottest months. The elevation of our property is also high enough to provide weather that will generally fluctuate between 30-80 Fahrenheit (0  to 25 C). For these reasons, the only non-passive cooling designed into this structure are the large-scale refrigerator and freezer and 2 swamp coolers for cooling the kitchen cooking and cutting/canning/preserving/dishwashing areas.

Q: Why are you designing this structure to be 100% off-grid? 

We feel it is important to demonstrate the Duplicable City Center and village models as options that can be constructed in locations without the availability of a connect to the power grid. For this reason, we are first designing the complete One Community energy infrastructure to supply all One Community village and City Center needs without a grid connection. Once these details have been completed and open source shared, we will also conduct and open source share the cost analysis comparison for connecting to the energy grid for backup power in the winter months when solar would normally require generator backup. After this analysis, we will update our plan if on-grid development is determined to be a more sustainable and cost effective option than generators and the additional batteries and solar infrastructure we’d need to function 100% off-grid in the winter months.
