our being state

7group is a collaboration between close friends which happens to be a business. We share a vocation – using our experience with green building as an instrument for developing the capacity of people to affect how humans regenerate life through building. We have worked on some of the “greenest” building projects in the world, but this alone is not enough. We seek to use each unique project’s design and construction process as an instrument for affecting the larger living systems in which that project is nested. As such, we work on developing each unique human’s capacity to play their role (and manifest their essence) in service to the vitality and viability of all life in that particular place. We see this as a process of reciprocity that seeks to grow and develop potential in each and all entities nested within the whole. We have found that the most effective nodal point for actualizing such systemic transformation is working on how we, as humans, are thinking about our role on the planet.

Our Essence

The Essence of 7group

“Humans are a part of nature, not apart from nature.” -Marc Beckoff

We believe that all of us want to make an positive impact on the world. In all humility all we can generally expect is to make a small dent. At our core 7group has been working together for over 20 years to use the “process of building” as an instrument for empowering systemic change in how humans live and inhabit our world. While our focus has expanded from technical systems to living systems, our aim remains the same. We explore connections, and develop interrelationships, that promote holistic affects. The trajectory of our thinking has led us to the obvious conclusion that humans need to re-member our contributory role as co-evolutionary participants in the council of beings, nurturing and contributing to the health of all life.

Our Beliefs, Philosophy and Principles


“Humans are nature”

Processes for developing how humans create and inhabit built environments can regenerate life.

  • Human world views evolve through processes of exchange.
  • The built environment has the potential for regenerating life.
  • All life is sacred.


“Everyone plays a valuable role”

Use every project and interaction as an instrument for developing our own and others’ capacity to engage regenerative thinking/doing/being with caring and compassion.


“The built environment serves as an instrument for regenerating life”

  • Develop regenerative thinking . . . by engaging people in regenerative processes that builds their capacities and capabilities. Everyone in the organization engages regenerative thinking in everything we do.
  • Make it real . . . regenerative frameworks must be grounded in reality to come alive.
  • Image potential . . . which emerges when seeing wholes, not working with fragments.
  • Everything is connected . . . and contributes to the whole through reciprocal interrelationships.
  • Be of service . . . to our clients and that which they seek to transform. Build systemic affectiveness in the way that we interact with everyone.
  • Give it time . . . to evolve and develop. Slowing the process regenerates the exchanges necessary for growth.
  • Beyond ourselves . . . people come alive and regenerate energy when contributing to the greater good by working on what they really care about.
  • Give it away . . . by sharing freely what we know and do not hold anything as proprietary. Give more than we take.
  • Manifest Essence . . . in our work. Each person and place is entirely unique.
Our Process

The process is the journey, it’s all about the journey.

Integrative Design

Our journey began more than 20 years ago with a focus on system thinking and an integrative process. We wrote a book on the subject with Bill Reed in 2009 that has become the definitive guide to the integrative design process as applied to green building projects.

A successful sustainable, or green, project is a solution that is greater than the sum of its parts. By intentionally building connections and cross-linked support between the engineered, cultural and natural systems present in all building projects, significant efficiencies, as well as natural system regeneration, can be achieved. Project and operating costs can also be reduced. Simply adding or overlaying individual “environmental” systems in isolation will not allow buildings and communities to benefit from the available connections and interdependencies that can be identified in an integrated, or whole system, design approach. This is the fundamental challenge of sustainable design.

The core concept of integrative design is simple – most everything in a building project affects everything else. Consequently, we examine how to integrate site parameters, solar orientation, water, stormwater systems, thermal envelope, lighting, window performance, heating and cooling supply systems, ventilation, and air distribution in a way that all of these systems are working together, much like those within an organism.

This design methodology constantly examines the tradeoffs between the up-front costs for pursuing the project goals and the benefits that are derived from achieving them. Design decisions are based upon analyzing, quantifying, and evaluating the synergistic interactions between building systems. Unlike conventional design, though, integrative design mandates closer interaction among the owner’s representatives, architects, engineers, and operations staff while they work together from the earliest pre-design phase to evaluate measures that can produce overall project savings, higher performance, and environmental benefits. We will initiate this interaction at the very beginning of this project by convening a goal-setting session with all stakeholders, followed by a focused and collaborative design charrette with all team members.

All projects have great potential for incorporating the most advanced green building design techniques and systems. However, there can a cost to pay in terms of budget as well as untested techniques; technically feasible solutions may not be right for operational simplicity and budget. Part of our job is to help find an optimal balance between the economic, cultural, and ecological areas of sustainability that will meet the objectives of our clients, yet allow for future adaptation of new technologies and interactions with the community. Our approach is one of common sense application of thoughtful and integrated solutions.

While we still apply an integrative process to all of our work, the epilogue to the book, Evolving the Field, foreshadowed when we were headed. The book ends with the question, “Where do we stop integrating?”. While working this way we discovered that applying an integrative process to technical systems was not enough. Our focus needed to shift from seeing buildings as the outcome, to buildings as a developmental instrument to achieve a larger purpose. The process requires an aim or direction toward regenerative, living systems.

Regenerative Whole-Systems Approach

Each particular place is alive, unique and evolving.  If we want to flourish over time, we must understand that we are in mutually beneficial relationship with each particular place and that humans play a participatory role in the vitality of the living systems in which we are nested.

The basis of regenerative whole-systems approach lies in understanding that role through understanding the uniqueness of each place we live and work – and what created and continues to create that unique identity. The cultural environment we call a community is a living system composed of many complex cultural and natural systems that form a web of mutual support. The health of cultural (and economic) systems is ultimately dependent on the health of natural – or living – systems.

Regeneration is rooted in the belief that healthy living systems have an inherent capacity to continually generate new sources of life for and within themselves and their environment – i.e., to re-generate. This work is grounded in a philosophy that humans (and human activities) are not apart from the development and ongoing evolution of such healthy living systems; rather, humans serve a participatory role in their continuing viability and vitality. Through the practice of developing how we are thinking in this way about whole living systems, any project can be leveraged as a highly effective acupuncture point for helping transform community vitality and regenerating life.

There are two interrelated dimensions in this regenerative planning work:

  • At its entry level, Regenerative Design is a practice for reversing the systemic decline in living systems and creating the basis for self-renewing socio-ecological vitality.
  • Regenerative Development is a continual process that builds the capacity, capability, and will of stakeholders to serve as co-designers and active participants in the continual evolutionary transformation of their unique place.

Regenerative Development and Design comprises a meta-discipline that combines the pattern thinking and practices of Ecological Design, Permaculture, Biophilia, Organizational Psychology, Neuroscience, and Integrative Design.

The purpose of regenerative development and design is to facilitate and guide the evolution of a place toward its highest creative and productive potential in a way that explores its unique nature and capacities (essence), so that planning and design efforts improve the capability of all living systems (including the larger whole-system in which each place is nested) to evolve towards higher levels of vitality and viability indefinitely. Through a series of workshops, participants experience this work through highly interactive engagement and discussion around how building and development can be seen as an instrument for healing, sustaining, and regenerating the community of life in each unique place by re-membering that we play a participatory role in the vitality of the living systems in which we are nested.

The process of working on projects from this whole living-systems perspective shifts the focus of everyone’s attention from simply solving problems and working only on “things” (such as buildings) to seeing any such project as an instrument for working on realizing the highest creative potential of the larger systems in which the project is nested (and inter-dependent). This shift in focus builds an understanding of the particular nature of each unique community/place and the particular reciprocal interrelationships (between human and “natural” systems) that create that uniqueness.

Working in this way awakens a deep and caring sense of place and meaning that becomes transformational by serving as the source of new community spirit and individual Will grounded in what people really care about. Communities all over the world currently engaged in this process are reconciling longstanding deep divisions, improving the quality of life for all inhabitants (all species), and delivering real value to all stakeholders by collaboratively co-creating processes of reciprocal exchange aimed at the health of the whole, not just the pieces.

The journey continues . . .

Our Roots
Origins of 7group

The original seven partners were:

Front L to R – Brian and Alan. Back L to R – Marcus, John, Andy, Scot, and Tom

Alan Barak, lawyer and social fundraiser

John Boecker, architect

Scot Horst, materials expert

Tom Keiter, filmmaker

Andy Lau, engineer, professor and modeling expert

Marcus Sheffer, energy expert

Brian Toevs, HVAC designer

Prior to forming 7group the original partners brought divergent but complimentary skills and experiences to the partnership.

Alan – was a lawyer by training.  He has an amazing ability to be a catalyst and convener to jumpstart worthwhile enterprises. He was actively involved in the central Pennsylvania region in assisting non-profits and institutions by bringing consultants and funding together to promote greener buildings. P.S. – Alan left 7group to become the Assistant Attorney General in Saipan and is currently Assistant General Counsel at the Washington, DC Department of Energy & Environment.

John – had worked in Connecticut, LA, Pittsburgh, and the Harrisburg area (for 14 years at the time of 7group’s founding) as an award-winning design architect focused on aesthetics and beauty. P.S. He experienced a bit of an epiphany in 1996 when he realized that focusing primarily on the aesthetics of building was leading to making decisions that deeply affected our environment in multiple negative ways . . . and that by expanding his and his teams’ focus and attention to addressing our larger ecology, even more beauty emerges.

Scot – was a classically trained opera performer. He also had been designing and making custom furniture for clients in New York City. He formed his own company in 1992 making VegTables and establishing his knowledge of green materials. P.S. – Scot later became the Senior Vice President at USGBC in charge of the LEED Green Building Rating System and is now the CEO of ARC Skoru.

Tom – was a Professor at Penn State who had founded and owned an award-winning film making company in State College, working for a wide range of national and international clients. P.S. – Tom worked at Penn State Public Broadcasting and continues to make films as a collaborator in storyshop films.

Marcus – has an environmental studies degree and a passion for developing solutions to environmental issues.  For 12 years he had worked for the Pennsylvania Energy Office (PEO) and had formed his own energy consulting firm, Energy Opportunities (EO) in 1993. Marcus and Andy had been working together on solar energy and energy efficient buildings since 1984. P.S. – more of the same with a deeper environmental focus.

Andy – had been working on solar energy and energy efficient buildings since 1977. Andy was a professor of engineering at Penn State Harrisburg and worked on projects with the PEO and on energy modeling of several buildings with EO. P.S. – Andy is an engineering professor at Penn State University Park teaching first-year design and sustainability.

Brian – a former student of Andy’s, began his career in HVAC design in 1987 and was always interested in “sustainability”. Brian had started his own mechanical engineering and design firm, BETA Engineers in 1997. P.S. – Brian’s firm transitioned their work into the then emerging field of building commissioning.

 7group Creation Story

On December 12, 1996 a meeting was convened to discuss the possibility of greening the upcoming Pennsylvania Department of Environmental Protection’s (DEP) South Central Regional Office Building (SCROB) in Harrisburg. Alan Barak was promoting green building in the Commonwealth under a grant from the Heinz Endowments.  He had a personal connection with the sister of the developer charged with building the project, so he was able to arrange the meeting. He then contacted Steve Lee, an architectural professor from Carnegie Mellon University, and Marcus Sheffer, an energy/environmental consultant, to arrange for them to assist him in pitching this new idea to the project team. John Boecker as the project architect, was also in attendance. The outcome ostensibly appeared somewhat predictable, since greening the project seemed to align with DEP’s mission, but Jim Toothaker, DEP’s Director of Building Systems and the person in charge of the project for DEP, responded by crossing his arms during most of the meeting clearly expressing his skepticism. However, Jim knew common sense when he heard it, and so he made the visionary call to “go green” . . . and 7group was born. The project ended up being one of the first 12 LEED Certified projects in the world.

From this origin, additional future partners in 7group worked on the SCROB project including Scot Horst, joined the team as the “green materials guy”; his research and skill resulted in his installation of green materials materials primarily in the lobby. Tom Keiter joined the team and was charged with producing a video about the project entitled Pennsylvania’s First Green Building.  The SCROB project was followed in succession by the PA DEP Cambria Office Building project in Ebensburg, PA. John was once again the project architect, Scot served as the green materials consultant, Tom made another series of videos, Marcus served as the energy consultant and brought in Andy Lau to do the project energy modeling. Andy in turn introduced us to Brian Toevs, who did the building commissioning.

More DEP projects followed and the future 7group partners began working together more and more frequently. Business relationships soon became personal friendships.  Once again serving as a catalyst and convener, Alan brought us together (over a beer at the picnic table in his backyard) and suggested we form a business partnership.

We all said “Of course, why not?”.
