CSCR Government #4: Climate Showcase Communities. Ed Marx, TCPD.
The document presents a project aimed at building sustainable communities, focusing on green building, energy efficiency, and social support systems. It highlights ten key principles for sustainable living, emphasizing density, local food production, and preserving open space. Success stories from the Ecovillage at Ithaca and other neighborhoods illustrate practical implementations of these principles.

Editor's Notes
- #3 Kick off message.: We want to demonstrate how governments, developers, and consumers can all be part of building a sustainable community that works. We are aiming for a high quality of life w/ extremely efficient resource use There is a model that includes all of these features and we have it now. Through 20 years of experience at EVI, the community has developed core principles that can be adopted in any community. There are two storylines - Tompkins County (government planning) and EVI (a sustainable community) coming together for a shared vision.
- #4 This is where we are today. The paradigm is shifting. Can we continue to live in the state of isolation and insatiable - desire for MORE - that we have fostered? “ Green costs too much” “ I want my privacy and control” These disconnected perceptions and desires drive our unsustainable lifestyles devoid of community. Following the path of where we stand now is fundamentally unsustainable for the planet and the people.
- #5 People Planet Profit OR Economy Equity Ecology OR Economy Health Environment – different ways of saying the same thing…SUSTAINABILITY! We are choosing the terms Economy Health and Environment to keep the message simple and mainstream. How do these principles, demonstrated at EVI, affect our economic bottom line, our physical and mental health, and our local environment. This Welcome Home project started thinking about some of the core ideas surrounding the sustainability movement. We are brining together the key stakeholders to invest in the process of developing actionable steps toward building a community that works.
- #6 What is the model and How does it work? The model we are promoting is based largely on the research that has come out of 20 years of studying EcoVillage at Ithaca. Let’s discover the lessons learned and then try to distill those into the core principles of creating a Community That Works! These are folks from FROG, the original neighborhood at EVI. Since that time the community has grown with the addition of a second neighborhood and now a third which is under construction.
- #18 Verbally describe some of the features of TREE.
- #21 Philosophical framework If a person experiences a built environment as a coherent whole, then the sense of place, feeling of belonging and experience of community is enhanced. Zoning is one major obstacle – our laws mandate some of the ugly and inefficient housing we have today. We are writing new policies which can be adopted by local municipalities These policies include a new pedestrian neighborhood zoning overlay and enhanced energy code which will allow developers to build sustainably.
- #22 The PNZ supports the emergence of Communities that Work by offering municipalities a zoning structure that promotes: Increasing density in urban areas so as to support transit and walkable communities Focusing density in rural/sub-urban areas so as to preserve land and promote closer social ties
- #23 Key strategies: Defined, yet permeable built perimeter that reinforces a welcoming sense of place but does not encourage sprawl A PNZ begins with planning around the 5 minute walk or approximately a ¼ mile distance. Most of our existing neighborhoods (in the Northeast) were planned around this concept and these are typically our most vibrant neighborhoods today. Human scaled walking distances, lot sizes and building sizes Shared outdoor space that is not disrupted by vehicles (pedestrian oriented space slide) Parking at the perimeter (on-street in urban locations) Resident governance and/or some kind of creative control Overall goal as a result of using these strategies: The goal is to promote higher density, energy-conscious, people-centered developments within the existing framework of predominantly automobile-centered zoning. The PNZ is a “floating zone” to be overlaid onto parcels within existing zones where focused density is deemed appropriate by a municipality The PNZ covers core principles, key definitions and standards. If a PNZ is applied we can achieve results like the ones demonstrated today and shown here. All of which would be illegal under our current zoning.
- #24 Our buildings use about 41% of all energy in the US. Residential buildings account for 22% plus a significant portion of the energy used for transportation. How can we take the principles of EVI and develop an energy code that takes us beyond minimum state building code requirements?
- #25 What are the impacts of existing codes on the physical infrastructure of communities? Mixed Use Neighborhoods: If all the needs of daily life are accessible within a 10 minute walk, vehicle use will further diminish. It is recommended that all neighborhoods be zoned so as to encourage the development of mixed uses. What are the impacts of existing codes on behavior choices that are available to us? Food not Lawns: EVI and APN best practices include provisions for on-site food production. This saves energy involved in agriculture and food distribution, and makes households more resilient. However, many communities restrict vegetable gardening to rear yards and mandate lawns and certain styles of landscaping in front yards
- #26 What are the code impacts on our building envelopes? Infiltration Rates: Current code allows 7 air changes per hour at a pressure of 50 Pascals (7ACH50). Climate Showcase homes are striving for the Passivhaus target of .6ACH50, and APN homes have reached .41ACH50, though at a cost that may be prohibitive for the mainstream. INHS uses more mainstream construction techniques and regularly achieves an infiltration rate of 2ACH50, which seems like a reasonable compromise. It is recommended that the maximum air infiltration rate be set at 2ACH50 for new construction. Thermal Bridging: Climate Showcase homes pay close attention to thermal bridging within the wall. Because of the wide variety of materials and wall systems available to builders, it is difficult to make a specific recommendation, other than that guidelines similar to those proposed for windows be introduced. What are the code impacts on the mechanical systems of our built homes? Air quality & ventilation: making our buildings too tight requires mechanical ventilation but this must be done carefully in order to be energy efficient. Desired outcome: Overall Efficiency: Though this requires actual testing which can increase cost, it could be a recommendation that new buildings achieve a HERS rating of 55 or less. INHS construction regularly tests at 50-52, so this is achievable at reasonable cost.
