The Buckminster Fuller Challenge invites today’s practitioners to answer his call "to make the world work for 100% of humanity, in the shortest possible time, through spontaneous cooperation, without ecological offense or the disadvantage of anyone.” What would Bucky do? Buckminster Fuller’s legacy is alive.

Over 150 villages in Germany produce all of the electricity and most of the heat they consume.  In these so-called "bioenergy villages," renewable energy systems are driving economic growth.   This session will provide an overview of the growing movement in Germany toward communally-developed and owned energy systems, focusing particularly on two villages in northern Germany.  The development process for these villages will be explored, as will the factors contributing to their success.

Session two will dig deeper into two solutions – both fresher paths forward than the expensive model of centralized-systems solutions. First is a look into cities such as Atlanta, where the cost of water and wastewater have soared but the system and the treatment technologies are working. Second is the promising practice of source-separating urine for fertilizer production—a pilot in Falmouth, MA is demonstrating cost-effective alternative to building a new treatment plant.

This session is in two parts.Water is scarcer. Systems for both fresh and waste water are vulnerable. Water standards are increasingly stringent to protect ecosystems and public health. Since water and energy are so inextricably intertwined, the term, “water grid" provides a unique frame for exploring how to operate a more closed-loop system of water production and use. As architects, engineers, builders and municipal planners, what will we have to rethink and re-do about processing fresh and waste water in developing the next generation of the built environment?

This session will showcase a range of ZNE district- and community-scale projects, including residential and mixed uses. The presenters will discuss the roles and relative importance of team, process, design, and technology in achieving their results. They will also present energy use data. An additional focus of this session will be the ways in which project scale influenced the project’s development and its performance.

Most of us take the electrical grid for granted. But it is perhaps the most complex technological achievement in human history. After more than a century of relative stability, the grid is changing fast. Our conference plenary will explore the technology and policy solutions evolving to enable a more reliable, resilient, environmentally responsible and affordable electricity grid.

As architects, engineers, and municipal planners, how can we rethink the built environment to install more urban food production and distribution in the city? An urban permaculture will frame the session, discussing practices such as: green roofs, pink houses, vertical growing walls, a farm-in-a-box and vertical farms. We will mix short presentations with facilitated conversation about how we, as urban practitioners, can shape the built environment to include urban food.

In 2011, Somerville launched a city-wide residential energy efficiency program aimed at a difficult-to reach demographic: middle income rental properties. Efforts to reduce residential energy consumption with its dense population required numerous alliances: utility leaders, a banking institution, and consultants worked closely together. Over 60% of Somerville households are occupied by tenants; renter/owner roadblocks were addressed. This presentation will examine municipality, utility and resident collaborations necessary to make such a program succeed.

In the face of extreme weather conditions, the practice of Building Energy must undergo two transformations: (1) What we do differently to alter the built environment;(2)how we better connect people living in a neighborhood. We have learned in the past 2 years of delivering BE 13 and 14 in resilient cities is this: community resilience is as important as resilience of the built environment. For example, creating a network of neighborhood businesses to stay open in a disaster. Developing a public community connectivity rating or altruism index.
