The Integrative Design Guide to Green Building: Redefining the Practice of Sustainability
About this book
The Integrative Design Guide to Green Building: Redefining the Practice of Sustainability 7group and Bill Reed Wiley, 2009 Since the early 1990s, the green building movement has made extraordinary progress in changing the way buildings are designed and constructed. Rating systems such as LEED have driven widespread adoption of energy efficiency measures, water conservation strategies, improved indoor air quality, and the use of materials with reduced environmental impact. Yet for all this progress, the authors of this landmark book argue, conventional green building practice remains fundamentally limited by a conceptual framework that addresses sustainability as a checklist of individual optimizations rather than as a property of the building as a whole living system embedded within larger living systems.
A building can earn points for efficient lighting, water-saving fixtures, and recycled content materials while still being, in its totality, a net drain on the ecological systems that sustain it. The Integrative Design Guide to Green Building proposes a fundamentally different approach — one grounded in systems thinking, whole-building analysis, and a conception of design as an ongoing, open-ended process of discovery rather than a linear sequence of decisions. The book is the collaborative product of two remarkable practitioners. 7group, based in Kutztown, Pennsylvania, is a firm whose principals — including John Boecker, Scot Horst, Tom Keiter, Andrew Lau, Marcus Sheffer, and Brian Toevs — have been involved in the development and implementation of the LEED Green Building Rating System since its inception, with direct experience on more than one hundred LEED projects.
Bill Reed is an architect, educator, and internationally recognized pioneer of integrative and regenerative design, a co-founder of LEED's technical framework, and a principal at the Regenesis Group, where his work has pushed beyond conventional sustainability toward what he calls regenerative development — design that restores and enhances the living systems within which buildings and communities are embedded. The book's first section establishes the philosophical and theoretical foundation for everything that follows. Reed and 7group draw on systems ecology, complexity theory, and the science of living systems to argue that buildings are not isolated machines but participants in the metabolic cycles of the places they inhabit.
Every building affects the hydrology of its site, the movement of air, the absorption and reflection of solar energy, the habitats of other species, and the social and economic patterns of the community around it. Conventional design treats these effects as externalities to be mitigated; integrative design treats them as opportunities to be shaped. The distinction is between a practice that asks 'how do we do less harm?' and one that asks 'how do we contribute positively to the systems we are part of?' Central to the authors' framework is the concept of 'whole-building' and 'whole-systems' thinking.
Where conventional building design proceeds by optimizing individual components — the mechanical system, the envelope, the lighting, the plumbing — in relative isolation from one another, integrative design insists on analyzing and resolving the interactions between systems from the earliest stages of the design process. The canonical example is the interaction between envelope performance, internal heat loads, and mechanical system sizing: a highly insulated, carefully designed envelope dramatically reduces the heating and cooling load, which in turn allows the mechanical system to be sized much smaller — potentially eliminating entire categories of equipment — which reduces the structural load from heavy mechanical infrastructure, which affects structural design, which affects material quantities and costs. This cascade of interactions, when recognized and leveraged from the outset, can produce buildings that are not merely more efficient but qualitatively different in their relationship to energy, water, and materials.
The discovery process — the structured investigation that precedes and informs design — is given particular emphasis. Rather than beginning with preconceived solutions or standard typologies, integrative design starts with a deep reading of the specific place: its climate, its ecology, its hydrology, its cultural history, and its aspirations. This place-based discovery phase surfaces the particular opportunities and constraints of the site and grounds all subsequent design decisions in a coherent understanding of context.
The authors describe how a thorough analysis of a building's solar exposure, prevailing winds, and thermal mass potential can lead to passive design strategies that dramatically reduce energy demand before any mechanical system has been specified. The book's manual section — comprising roughly half of the total volume — is organized around thirteen explicit stages of the integrative design process, from pre-design discovery through schematic design, design development, construction documents, construction phase, and occupancy. Each stage is described with process outlines, specific tasks, and questions the design team should be asking at that point.
The book emphasizes that the integrative process is not simply a matter of scheduling more meetings or adding more consultants; it requires a different kind of conversation, one in which specialists from different disciplines genuinely engage with each other's domains rather than exchanging information across disciplinary boundaries. Case studies from real projects illustrate how the integrative approach plays out in practice across a range of building types, scales, and climatic contexts. These examples are notable for their candor — the authors do not present only successes but also describe projects where the integrative process was imperfectly implemented and what was lost as a result.
A recurring theme is the relationship between integrative design and widely used rating systems, particularly LEED. The authors are deeply familiar with LEED — indeed, they helped create it — and they argue that while it has been tremendously valuable as a market transformation tool, its checklist structure can actually work against integrative thinking by encouraging project teams to optimize individual credits rather than pursuing the whole-systems interactions that could yield far greater performance. The book is therefore both a complement to and a gentle critique of prevailing green building practice.
In its concluding sections, the book gestures toward the horizon of regenerative design — a practice that goes beyond sustainability (maintaining current conditions) toward restoration and enhancement of the living systems upon which all human activity depends. This dimension of the book, particularly associated with Bill Reed's contributions, points toward a more ambitious vision of what the built environment could be: not merely less damaging, but actively life-giving. This book is essential for architects, engineers, interior designers, landscape architects, developers, owners, and anyone seeking to move beyond the checklist approach to sustainability and engage with building design as a whole-systems practice.
