'Net positive', from Positive Development (PD) theory, is a paradigm in sustainable development and design. PD theory (taught and published from 2003)Birkeland, J.

Net positive sustainability
According to PD, the original precepts of sustainability (nature preservation and equity among current/future generations)These principles are common to most early definitions of sustainability and were endorsed at a national level as early as 1969 in the preamble to the National Environmental Policy Act (NEPA) in the United States. Among the first international documents to define sustainability was the IUCN/UNEP/WWF (1980) World Conservation Strategy, re-published in 1991 as Caring for the Earth: A Strategy for Sustainable Living, The World Conservation Union, United Nations Environment Program and World Wide Fund for Nature, Earthscan, London, UK. Here it meant improving life quality within the earth's ecological carrying capacity. See also COAG (1992) The National Strategy for Ecologically Sustainable Development (NSESD), Council of Australian Governments, Canberra, Australia. For historical context, see Commoner, B. (1971) The Closing Circle: Nature, Man And Technology, Knopf, New York and Porritt, J. (1985) Seeing Green: The Politics of Ecology Explained, Blackwell Publishers, UK. require increasing future options.Social options do not mean more consumer products but rather substantive and positive life choices which requires increasing the ecological base and public estate. This, in turn, requires that development increase the social and natural life support systems.The idea that sustainability requires maintaining or increasing future option was discussed in Birkeland, J. (1993) Planning for a Sustainable Society: Institutional Reform and Social Transformation, University of Tasmania, Hobart, Tasmania. See also Norton, B.G. (2005) Sustainability: A Philosophy of Adaptive Ecosystem Management, University of Chicago Press, Chicago, Illinois for a comprehensive discussion on this point. Green design always aimed for ecological restoration, social regeneration and economic revitalization.For a typology of green building design, see Birkeland, J. (2013) 'Business Opportunities through Positive Development', in A New Dynamic: Effective Business in a Circular Economy, in K. Webster, J. Bleriot, and C. Johnston (Eds), Ellen MacArthur Foundation Publishing, Isle of Wight, UK, pp. 87-110. However, these essentially only 'add value' relative to current sites, buildings or practices.For a discussion of contemporary sustainable building design approaches, see Hes, D. and du Plessus, D. (2015) Designing for Hope: Pathways to Regenerative Sustainability, Taylor & Francis, New York. USA. Green buildings are generally assessed as 'sustainable' if they improve upon best practices. They do not yet aim to increase nature, environmental security or justice in absolute (global) terms. Positive Development, in contrast, is defined as structures that increase universal life quality and future options by expanding the 'ecological base' (ecosystems, ecological carrying capacity, biodiversity) and the 'public estate' (universal access to means of survival/well-being and social capital).Birkeland, J. (2007) 'GEN 4: 'Positive Development', BEDP (Built Environment Design Professions) Environmental Design Guide of the Australian Institute of Architects, ACT, Australia. http://www.environmentdesignguide.com.au/ Assessed June 2008. Sustainable design does not yet aim to increase overall natural and social life support systems and generally limits its focus to the health and environmental quality within the project's system boundaries. The mainstream perspective is probably because it is assumed that this is not possible. To address this, a PD [http://netpositivedesign.org website] provides examples of how the built environment can address 30 crucial sustainability issues.
Terminology
The term net positive is increasingly used by green designers,The term also appears as 'net-positive' or 'netpositive'. A special issue was dedicated to net-positive design. See Cole, R. (2015) 'Net-zero and Net-positive Design: a question of value', in Building Research & Information 43(1), pp. 1-6. developers and businesses.For example, see Forum for the Future, WWF, and The Climate Group (2015) Net Positive: A New Way of Doing Business. Available at http://www.theclimategroup.org/what-we-do/publications/net-positive-a-new-way-of-doing-business/ Accessed June 2015. However, they often apply it from a different perspective: 'giving back more good than bad'. That is, relative to current conditions, not to sustainability.Benchmarks are relative to the present, so eco-restoration is seen by some as net positive, yet this does not account for past biodiversity losses and increased human consumption. In effect, this mean optimizing material resources, energy and stakeholder benefits, etc., or efficiency, not an overall (global) gain. This 'reductionist' approach was the aim of 20th-century green building design.There are a wide range of 20th Century green design books, including: Papanek, V. (1971) Design for the Real World: human ecology and social change, Pantheon Books, New York; Johnson, R. (1979) The Green City, MacMillan: S. Melbourne, Australia; Todd, N. and J. Todd (1994) From Eco-Cities to Living Machines, N. Atlantic Books, Berkeley, CA.; Vale, B. and R. Vale (1975) The Autonomous House: Design and Planning for self-sufficiency, Thames and Hudson Ltd, London; Wann, D. (1996) Deep Design: Pathways to a Liveable Future, Island Press, Washington, DC.; Lyle, J.T. (1994) Regenerative Design for Sustainable Development, Wiley & Sons, New York; van der Ryn, S, and Cowan, D. (1996) Ecological Design, Island Press, Washington, DC. Mackenzie, D. (1991), Green Design: Design for the Environment, Lawrence King, London; Girardet, H. (1992), The Gaia Atlas of Cities: New Directions for Sustainable Urban Living, Gaia books Ltd, London; and Yeang, K. (1999) The Green Skyscraper: The Basis for Designing Sustainable Intensive Buildings, Prestel Verlag, Munich, Germany [Yeang has written numerous books on green design]. PD emphasized the need for development to be net nature positive, since nature had been largely ignored in sustainable or regenerative design until recently.
A key feature that distinguishes the term net positive in PD from misinterpretations of the original usage is that PD separates nature restoration from nature net positive. This is because reductions in negative impacts are not net gains. Calling buildings net positive if they have more positive than negative impacts is a basic misunderstanding of PD accounting.{{Cite web |title=Buildings Alone Will Never Be 'Regenerative' – Architecture . Construction . Engineering . Property |url=https://sourceable.net/buildings-alone-will-never-be-regenerative/ |access-date=2024-05-06 |website=sourceable.net}} Often, in conventional building assessment, reductions in negative impacts are sometimes called 'positive', many kinds of negative impacts are omitted, and negative impacts as judged to be somehow erased by adding positive impacts. The word 'net' in sustainability assessment necessarily means net in a whole-system sense. In PD, 'net' means public benefits beyond neutral impacts - not just reductions in the total negative impacts to zero by, for example, counting offsets or making tradeoffs.For an overview of zero-energy building, see Kibert, C.J. and Fard, M.M. (2012) Differentiating among Low-energy, Low-carbon and Net Zero-energy Building Strategies for Policy Formulation, Building Research & Information, 40(5), pp. 625-637.
Theory origins
PD theory built on eco-philosophies that emerged in the 1980s.See for example, Merchant, C. (1980) The Death of Nature: Women, ecology, and the scientific revolution, HarperCollins, New York; Warren, K. (1997), Ecofeminism: Women, Culture, Nature, Indiana University Press, Bloomington, Indiana; Naess, A. (1989) Ecology, community, and lifestyle, Cambridge, Cambridge University Press, UK; Warren, K. and Wells-Howe, B. (1994) Ecological Feminism, Routledge, New York; Salleh, A. (1997) Ecofeminism as Politics: Nature, Marx and the Postmodern, Zed Books, London; Shiva, V. (1988) Staying Alive: Women, Ecology and Development, Zed Books, London. Calling for social transformation, they deconstructed the hierarchical cultures, dualistic thought patterns and linear-reductionist analyses of modernity. PD added a positive/negative overlay to explain why these theories did not contemplate increasing nature to offset consumption. Later, sustainability was absorbed into the dominant paradigm (DP) which assumed that current institutions could resolve the problems they fostered.See WCED (1987) Our Common Future, Report of the World Commission on Environment and Development. Oxford University Press, Oxford, UK. This seminal report couched sustainability within the dominant economic and policy making frameworks and did not engage with the sustainability literature critical of the dominant paradigm. According to PD, existing institutional and physical structures reduce future options and are thus terminal.Planning for Sustainability, Ibid. Birkeland, J. (2008) Positive Development, Ibid. The hypothesis was that, by converting negative systems into positive ones, genuinely sustainable planning, decision and design frameworks would materialize.
= Design-decision distinction =
The distinction between decision-making and design is central to PD.{{Cite journal |last=Birkeland |first=Janis |author-link=Janis Birkeland |date=May 2012 |title=Design Blindness in Sustainable Development: From Closed to Open Systems Design Thinking |url=http://www.tandfonline.com/doi/abs/10.1080/13574809.2012.666209 |journal=Journal of Urban Design |language=en |volume=17 |issue=2 |pages=163–187 |doi=10.1080/13574809.2012.666209 |issn=1357-4809|url-access=subscription }} Decision-making processes/tools divide, compare and choose. They use bounded or 'closed system' thinking which excludes considerations that are difficult to quantify. Essentially, decision methods simplify issues and options to facilitate finding the best path from the present position or desired future. Back-casting and scenario planning, while powerful tools, presume the future can be predicted and selected.Positive Development, Ibid, pp. 165-179 Such methods decide now how future citizens must live. They also reduce future options by narrowing resources, adaptability, space and biodiversity over time.
= Decision-making =
The reduction of the ecological base and public estate continues, PD argues, because new sustainability goals were spliced onto the old (anti-ecological) closed system models, methods and metrics of the DP.Positive Development, Ibid. Given escalating human consumption, even global depopulation and ecological regeneration would not counterbalance total negative resource flows and ecological impacts. PD maintains that closed system models created and institutionalized zero-sum decision and measurement frameworks such as cost-benefit/risk-benefit analyses.Positive Development, Ibid, pp. 117-130. It identifies and 'reverses' over a hundred systemic biases in governance, planning, decision and design frameworks by converting them into open system and design-based frameworks to facilitate eco-positive planning and design.{{Cite web |title=Net-Positive Design and Sustainable Urban Development |url=https://www.routledge.com/Net-Positive-Design-and-Sustainable-Urban-Development/Birkeland/p/book/9780367258566 |access-date=2024-05-08 |website=Routledge & CRC Press |language=en}}
Whereas the internal logic of decision frameworks tend to diminish ecosystems and land eco-productivity, eco-logical design (creating) can multiply functions and public benefits synergistically. Eco-positive design involves open systems thinking (i.e. with transparent/permeable boundaries). For example, building rating tools are based on limits or thresholds (borders) and do not contemplate net public gains. Perhaps because of the deeply-embedded historic elevation of rationalist decision-making over design, green building design templates and rating tools are decision-based. Being reductionist, they encourage tradeoffs between costs and benefits or nature and society in physical development. Hence, they tend to reduce adaptability, diversity and reversibility.There are many critiques of green building rating tools. Brandon, P.S., and Lombardi, P.L. (2011) Evaluating Sustainable Development in the Built Environment (2nd ed.) Chichester, West Sussex, Ames, Iowa, Wiley-Blackwell; Gu, Z., Wennersten, R., and Assefa, G. (2006) 'Analysis of the Most Widely Used Building Environmental Assessment Methods', Environmental Sciences, 3(3), pp. 175-192; Birkeland, J. (2004) 'Building Assessment Systems: Reversing Environmental Impacts', Nature and Society Forum, ACT, Australia http://www.naf.org.au/naf-forum/birkeland (accessed 2005).
Governance
Decision systems in governance (i.e., legislative, executive and judicial) resolve conflict by allocating rights and resources—not by increasing the ecological base and/or public estate. Hence PD suggests different frameworks for environmental governance.Birkeland, J. (1996) 'The Case for a New Public Forum', in Furnass, B., Whyte, J., Harris, J., and Baker, A. (Eds), Survival, Health and Wellbeing into the 21st Century, Nature and Society Forum, pp. 111-114. Birkeland, J. (1995) 'Ethics-Based Planning', Australian Planner 33(1), pp. 47-49. These include a modified constitution with a new decision sphere to deal with the unique ethical dimensions of biophysical development, planning and design.Birkeland, J. (1993) 'Towards a New System of Environmental Governance', in The Environmentalist, 13(1), pp. 19-32; Birkeland, J. (1993) Planning for a Sustainable Society, Ibid; Birkeland, J. (2008) Positive Development, Ibid, pp. 220-233. Given real-world political barriers to change, PD also suggests default strategies to enable incremental reform by changing institutions from within. PD contends that gaps can be avoided in new governance and planning systems by simply reversing each ecologically terminal convention into eco-positive ones.
Design and planning
While improved systems of governance, decision-making and planning can assist, biophysical sustainability is ultimately a design problem. To compensate for past system design errors, fundamental reforms of design methods and processes are required. PD proposes means to reduce material flows without tradeoffs by, for example, creating mutual gains and 'low-impact luxury' environments. PD contends that eco-positive design is already possible, partly through the integration of natural systems with building structures, spaces and surfaces (e.g. 'living machines', mycology, or 'algaetecture'). PD contributes other design concepts (e.g. 'design for eco-services', 'green scaffolding' 'green space walls', 'solar core' and 'piggyback roof, or 'playgardens').Digital sustainability can stimulate empirical advances in entrepreneurship, innovation and strategy and has the potential to have a positive impact on society.
SMARTmode (systems mapping and redesign thinking) is a PD planning processPositive Development, Ibid, pp. 251-173. that includes two dozen environment gap analyses to highlight sustainability issues that are almost never assessed in planning or design.Birkeland, J. (2015) 'Planning for Positive Development', in J. Byrne, J. Dodson and N. Sipe (Eds), Australian Environmental Planning: Challenges and Future Prospects, Routledge, pp. 246-257. Some of these are forensic 'flows analyses' that identify (local/regional) social and ecological deficits that developments could ameliorate by design. They can be undertaken scientifically using emerging multi-dimensional digital mapping tools,Jackson, D. and Simpson, R., eds. (2012) D_City: Digital Earth, Virtual Nations, Data Cities, D_City, Sydney, Australia. more pragmatically by design teams,Birkeland, J. (1996) 'Improving the Design Review Process', CIB Commission Conference Proceedings, RMIT, Melbourne, pp. 150-155; Birkeland, J. (2014) 'Systems and Social Change for Sustainable and Resilient Cities', L. Pearson, P. Newton and P. Roberts (Eds), Resilient Sustainable Cities, Routledge, UK, pp. 66-82. or more subjectively in community 'charrettes' (aka working bees) for workshopping planning criteria and design briefs.Sarkissian, W. (2002) 'Pros and cons of design charrettes', in J. Birkeland (Ed) Design for Sustainability: A Sourcebook of Integrated Eco-logical Solutions, Earthscan, London, p. 113. Until planners perform these analyses routinely, therefore, they can serve as design thinking exercises, guidelines and/or criteria.
Eco-positive retrofitting is a priority PD strategy.Birkeland, J. (2009) 'Eco-Retrofitting with Building Integrated Living', in Smart and Sustainable Built Environment Conference Proceedings. Delft, Netherlands. www.sasbe2009.com/ accessed May 2011; Positive Development, Ibid, pp. 23-41. Due to the massive ongoing impacts of buildings, biophysical sustainability is impossible without retrofitting cities.UNEP (2013) Buildings and Climate Change: Summary for Decision Makers, United Nations Environment Programme (UNEP), Nairobi (by United Nations organizations and national building institutes). UN-HABITAT (2011) Cities and Climate Change: Global Report on Human Settlements. http://www.unhabitat.org/downloads/docs/GRHS2011_Full.pdf/ accessed July 2012 Replacing buildings with greener ones costs too much in materials, money, energy and time, as new buildings represent only 1–3% of the building stock.Romm, J.

= Eco-services design =
The term 'ecosystem services' generally applies only to human benefits, which are usually valued by units (e.g. money, carbon or energy.Costanza, R. et al. (1997) 'The Value of the World'sEcosystem Services and Natural Capital', Nature, vol 387, pp. 253–260; Heal, G. (2000) Nature and the Marketplace: Capturing the Value of Ecosystem Services, Island Press, Washington, DC; Folke, C. Jansson, Å., Larsson, J. and Costanza, R. (1997) 'Ecosystem Appropriation by Cities, Ambio Vol 26, pp. 167-172; Daily, G. and K. Ellison (2002) The New Economy of Nature, Island Press, Washington, DC. PD uses the term 'eco-services' to include not only nature's instrumental (pragmatic) values like ecosystem goods and services, but its intrinsic (priceless) and 'biophilic' values.Wilson, E.O. (1993) The Biophilia Hypothesis, in S. Kellert (Ed) Island Press, Washington DC. PD considers the value of nature to be 'infinite' as it is not only the basis of the economy, but essential to human existence itself. To counteract the ecological footprint of existing development,Wackernagel, M. and Rees W. E. (1996) Our Ecological Footprint: Reducing the Human Impact on the Earth, New Society Publishers, Gabriola Island, British Columbia. 'surplus' natural and social capitalSurplus in PD means 'giving back more than it takes' from a life cycle and whole system perspective, not sending energy or water back to the grid or mains.—assessed from fixed biophysical baselines—must be created both off-site and on-site by design.
= Carbon-neutral design =
Net positive energy is barred by the laws of physics. Calculations of 'net energy' seldom include the embodied energy and the ecological impacts incurred during resource extraction, production and transportation. A case study showed that a building sequestering more carbon than it emits over its life cycle with building-integrated vegetation using PD design principles is possible within under twelve years.Renger, C., Birkeland, J. and Midmore, D. (2015) 'Net Positive Building Carbon Sequestration: A Case Study in Brisbane', in Building Research and Information: Special issue on net positive design 43(1), pp. 11-24. See also Birkeland, J.L. (2008) 'Space Frame Walls: Facilitating Positive Development', in Proceedings of the 2008 World Sustainable Building Conference. Melbourne, Australia, September 22–25, http://trove.nla.gov.au/ accessed June 2009.
= Design reporting =
The PD eco-positive design reporting process (EDR)Birkeland, J. (1996) 'Improving the Design Review Process', CIB Commission Conference Proceedings, RMIT, Melbourne, pp. 150-155; Birkeland, J. (2014) 'Systems and Social Change for Sustainable and resilient Cities', L. Pearson, P. Newton and P. Roberts (Eds), Resilient Sustainable Cities, Routledge, UK, pp. 66-82. aims to avoid many shortcomings of decision-based approaches to design.Birkeland, J. (2008) Positive Development, Ibid, pp. 83-96. Rating tools often give credits for things that have financial gains like energy and water savings or worker health and productivity but do not increase the ecology, let alone offset biodiversity impacts. They do not credit actual net positive impacts. In contrast to green building rating tools, the EDR aims to uncover opportunities to create net public gains. Design teams answer questions based on PD design criteriaPositive Development, Ibid, pp. 257-258. and SMARTmode analyses.Birkeland, J. (2015) 'Planning for Positive Development', in J. Byrne, J. Dodson and N. Sipe (Eds), Australian Environmental Planning: Challenges and Future Prospects, Routledge, pp. 246-257; Positive Development, Ibid, pp. 251-273. This forces education, collaboration and 'frontloading' design (i.e. investing more in preliminary design stages).See Weizacker, E. van, Lovins, A. and Lovins, H. (1997) Factor 4: Doubling Wealth – Halving Resource Use, Earthscan, London, UK. Hawken, P., Lovins, A and Lovins, H. (1999) Natural Capitalism: Creating the Next Industrial Revolution, Earthscan, London, UK. It is a widely cited claim that design is only about one percent of the total cost of the building, yet can save fifty to ninety percent of the total operating cost of a building. Exposing the research and reasoning behind decision and design concepts facilitates input from community, assessors and independent experts, and should therefore occur be undertaken in development project.An example EDR process was created for Bogota based on a study of cultural, economic, social, ecological and other special needs. This is not yet published.
= Assessment =
Most rating tools prioritize resource efficiency and treat 'reductions in negative impacts' as if positive. Their baselines and benchmarks preclude net-positive impacts. Some provisions consider respective rights/responsibilities, but not broader ethical issues like improving human-nature relationships, reducing total resource flows or increasing social capital in the vicinity. Also, innovation is often valued for its own sake, not outcomes, and eco-efficiency saves owners money anyway. PD's 'hierarchy of eco-innovation' analysis instead prioritizes positive system-wide outcomes and net public benefits.The PD 'hierarchy of eco-innovation' is summarized in Birkeland, J. (2008) Positive Development, Ibid, pp. 240-242. Being non-numerical, it allows self-assessment during design when scientific data is unavailable, time and ego has vested or irreversible decisions are made.
== PD Starfish ==
The PD Starfish design and rating tool enables quantification while assisting designers to consider more dimensions of sustainability.Birkeland, J. (2010) 'Starfish Tool for Net Positive Design', Presentation at Positive Communities, DEEDI (Queensland Government), Brisbane; Birkeland, J. (2012) 'Design blindness in Sustainable Development: From Closed to Open Systems Design Thinking', in The Journal of Urban Design, 17(2), 163-187. (Note the tool is elaborated in a forthcoming book). It is a modified radar diagram with added layers and satellite diagrams.Radar diagrams are standard spreadsheet tools. Since most life-cycle assessment tools estimate impacts between '-1' (bad) to '0' (best) or zero impact, eco-positive public benefits are excluded. Unlike rating tools, benchmarks for different sustainability factors are based on fixed biophysical conditions—not typical buildings, sites or practices.Jackson, D and R. Simpson (2012) D_City: Digital Earth/Virtual Nations/Data Cities - Connecting Global Futures for Environmental Planning, D. Jackson and R. Simpson, E-book, http://dcitynetwork.net/manifesto/; Birkeland, J. (2012) 'The Eco-Positive Design Tool', in Solar Progress, Journal of the Australian Solar Energy Society. The starfish uses one scale to assess impacts in relation to fixed benchmarks (from '-1' to '+1') and a linear scale on another layer for scoring/comparison purposes.
