Meeting the Moment
The 2025 Super Summit marked a series of firsts:
“Our intention was to lean into the challenges of this moment, to give each network space to connect internally AND to connect with the other networks. Despite a few hiccups along the way — including an extended power outage that validated our commitment to natural light — we achieved all those goals. The sharing was rich and meaningful, driven as always by the passion and generosity of this community. Thank you all for coming, and for all that you do to keep moving us forward.”

Pre-Summit Workshop:
From Transactional to Transformative: Building Relationships for Change
David Jay, author of Relationality, led a practical, interactive session exploring how grassroots organizing can inform purposeful relationship-building in the field of sustainability. Participants used reflection and roleplay to craft personal stories that connect around shared purpose, then strategized ways to build trust and generate buy-in for change.
The transactional versus the transformational awareness. I hadn't thought about it in that way, but it makes a lot of sense. I'm aware of it now, and that's the first step. The next step is understanding how to engage in the transformational.
…this workshop was a god-
send for engagement tactics and leading in a contentious topic area.

Redefining Collective Goals
2030 Challenge was a jumping-off point, but between DDx and Materials Pledge it’s too much reporting! Too onerous.
Beyond 2030, what are we talking about? Operational carbon was clear, fossil fuel-free was clear under the challenge, but there’s lots more in the bucket…

Architects + Engineers Setting Scope and Fee
75% of success comes from setting the right scope.
Consider a template based on ASHRAE 209.
Architecture firms can have a roster of prequalified engineers already on IDIQ contract.
25% of success comes from schedule, so can meet goals and mitigate risk of non-compliance.

29
Leveraging Design-Build for High Performance
Establish sustainability goals from the beginning, with everyone on the team.
Keep re-establishing the goals (“those people don’t work here anymore…”)
Project delivery model really matters. Success is easier with some. Have to bring entire team along the whole way.
Relationship-building is key. After doing it once with a partner, it’s easier the second time.

Firm Structures to Support Sustainability Outcomes
Who’s responsible for building relationships?
How do we think about accountability?
Start by understanding how decisions get made at the firm.
Then work to to structure sustainability within decision making, bringing clarity to how it happens.
Don’t conflate day-to-day tactics with strategic decisions.
Embed sustainability into strategic plans, visions, and mission statements.

How to create life over time? Look for the healthy situation; grab that rudder and guide it.
Applies to any stage of staff development: owners, but also subject matter experts, other staff.
What are we teaching?

Inspirations in Our World
What We’re Taking With Us
2025 Super Summit
65
Connecting with people who get it and who are willing to collaborate to move the needle.
Renewal. The summits are a reminder that we are not alone. This is just a few months from
our firm's strategic planning efforts, so re-energizing was important. It was a very timely dialogue.
Keep on working towards the goals, even if it seems like we are working against the current.
Progress is being made. We can learn how to make it meaningful to others by finding different
ways to connect.
The succession planning, mentorship discussions made me start to think more intentionally about my role. I'm in position of influence with a set of unique skills, but it's more like a stewardship role than a temporal position. There are those who came before and will come after. We are participating in a continuum of action. Consciously engaging in a continuum is very different than limiting your perspective to your role in the present and the immediate future.
I learned where my firm sits among this peer group on many topics. In some areas we are
doing great, are further along a change management spectrum, and are making a real impact in areas others are struggling. And in other areas I can look to some of my peers as examples as I try to accelerate my firm's progress.
Some great thoughts on storytelling and ideas on how to approach pitching the "why" to folks that may not share my passion.
We are in this together - the grief, the challenge, AND the adventure.
Closing Reflections
2025 Super Summit
66
It felt both completely wild and appropriate to spend a whole morning talking about the Moment we are in. I'm so accustomed to these Summits being focused exclusively on the technical - and yet, what holds us back right now is not the technique, tools, or technology, but the political willpower (or motivation? energy? strength?).
To share knowledge and motivation from others across the industry — the opportunity to connect across the peer networks made it impossible to pass up.
It is always a balance between sharing and actionable outcomes. I default to action. I would have liked more of that. There are a range of participants. Technical project focused folks and those more focused on firm change and culture. It might be useful to think about how to meet the needs of these differently.
Having so many different conversations and the ability to connect with so many different people. It was logistically difficult, I know, but it was worth it.
Chance to connect with others, share ideas, and find positive ways to stay engaged in current political climate.
Best event of the year! Would hate to miss it!
The people! Met some really wonderful new people. And had space to spend quality time with
new and old.
This is a great environment to continuing growing my leadership capacity.
This convening was a powerful cross-section of generations, disciplines, regions, and perspectives.

DRAFT Mission Statement:
The Sages share experience, capacity, and knowledge, to propel our peers (Peer Network members, firms, and communities) beyond where we’re at today.

73
How to Help Everyone See/Expand Discussions on Shared Concerns?
Sages can be a sounding board for the Peer Networks to test ideas/let them bounce ideas off us/to reframe ideas.
Sages can be connective tissue - collectively we have a big rolodex (once we explain what a rolodex is) … both within our network and beyond.
