This article introduces BioZero, a nature-inspired near-zero building proposed for Quay St, Brooklyn, New York. The building is designed for the maximum use of daylight and natural ventilation. This is the result of its shallow plan depth and the inner light wells/ventilation stacks, which also serve the inner circulation space. The light wells/ventilation stacks are created as a result of the organic shape of the internal partitions. The building is constructed from a steel frame and hemp-lime bio-composite material (hempcrete), which smooths out the fluctuations of internal air temperature and relative humidity. The south facing façade is fitted with the Cadmium Telluride (CdTe) photovoltaic array that covers 90% of the opaque surface area of the façade. The design was based on nature-inspired computation, with sustainability principles as guiding constraints. The main findings are that the building achieves −227 tonnes of negative embodied carbon due to sequestration of CO2 in the hemp plant from which the material was harvested, and a net-zero operation. The main conclusions are that in the context of climate emergency, nature inspired design leads to energy efficient buildings with a high level of thermal comfort, which are buildable and sustainable.

Traditionally, the uniform application of thermal insulation is practised within the built environment sector to achieve desired building regulation standards for energy efficiency. However, that approach does not follow the building heat loss field, and it is therefore poorly matched to the actual heat loss from the building, thus achieving sub-optimum energy performance. This research aims to visualise building heat loss field in three dimensions and to create self-organised thermal insulation patterns that are proportional in thickness to the intensity of heat loss. This is achieved using a 3D agent-based model, in which each agent that represents a miniature object of thermal insulation moves up the gradient of the heat loss representation and competes for its position with the neighbouring thermal insulation components, depending upon the gradient intensity. This creates a self-organised thermal insulation pattern through the competition between the thermal insulation components and through overcrowding in the areas with higher heat loss intensity. This helps to visualise the heat loss field and create a representation of thermal insulation that is ideally matched to it. The result is assessed for its energy performance using a conventional energy performance analysis. That analysis shows that this approach leads to reductions in energy consumption and carbon emissions in comparison with the conventional approach that uses the same amount of thermal insulation material. The overall result increases our understanding of 3D heat loss and introduces a new approach for designing building thermal insulation.

The ultimate aim of sustainability in buildings gained an additional new dimension as the start of the year 2020 saw a rapid worldwide spread of the infectious disease caused by a coronavirus named COVID-19. There is evidence that, in addition to person to person contact, the disease transmission occurs through airborne droplets/aerosols generated by breathing, speaking, coughing or sneezing. For that reason, building heating, ventilating and air conditioning systems can play an important role, as they may both contribute as well as reduce the transmission risk. However, there is insufficient understanding of the movement of infectious aerosols in buildings. This article introduces a method of bottom-up emergent modelling of the movement of infectious aerosols in internal space using a physics engine, and reports on simple simulation experiments. The results show that the smallest droplets that are large enough to contain the virus can be suspended in the air for an extended period of time; that turbulent air flow can contribute to the infectious aerosols remaining in the room; and that unidirectional air flow can contribute to purging the room of the infectious aerosols. The model introduced in this article is a starting point for further development and for increasing our understanding of the movement of infectious aerosols in buildings, and thus for increased sustainability of building design.

The staggering complexity of urban environment and long timescales in the causal mechanisms prevent designers to fully understand the implications of their design interventions. In order to investigate these causal mechanisms and provide measurable trends, a model that partially replicates urban complexity has been developed. Using a cellular automata approach to model land use types and markets for products, services, labour and property, the model has enabled numerical experiments to be carried out. The results revealed causal mechanisms and performance metrics obtained in a much shorter timescale than the real-life processes, pointing to a number of design implications for urban environments.

Financing building retrofit projects that contribute to climate change mitigation has always represented a significant barrier. With 28% of global emissions coming from existing buildings, it is of paramount importance to carry out retrofit measures that lead to significant reduction of these emissions. Whilst this is perfectly possible to achieve with current methods and current technology, there is no sufficient conventional finance to carry out zero carbon retrofit at scale required for climate change mitigation. The article introduces an alternative and sustainable business model that creates new opportunities for financing zero carbon retrofit of buildings. It demonstrates that the value of solar energy falling on roofs of buildings can become a driver for new local economic systems, and discusses the requirements for practical application.

Buildings contribute to nearly 30% of global carbon dioxide emissions, making a significant impact on climate change. Despite advanced design methods, such as those based on dynamic simulation tools, a significant discrepancy exists between designed and actual performance. This so-called performance gap occurs as a result of many factors, including the discrepancies between theoretical properties of building materials and properties of the same materials in buildings in use, reflected in the physics properties of the entire building. There are several different ways in which building physics properties and the underlying properties of materials can be established: a co-heating test, which measures the overall heat loss coefficient of the building; a dynamic heating test, which, in addition to the overall heat loss coefficient, also measures the effective thermal capacitance and the time constant of the building; and a simulation of the dynamic heating test with a calibrated simulation model, which establishes the same three properties in a non-disruptive way in comparison with the actual physical tests. This article introduces a method of measuring building physics properties through actual and simulated dynamic heating tests. It gives insights into the properties of building materials in use and it documents significant discrepancies between theoretical and measured properties. It introduces a quality assurance method for building construction and retrofit projects, and it explains the application of results on energy efficiency improvements in building design and control. It calls for re-examination of material properties data and for increased safety margins in order to make significant improvements in building energy efficiency.

The article introduces the process of deep energy retrofit carried out on a residential building in the UK, using a ‘TCosy’ approach in which the existing building is completely surrounded by a new thermal envelope. It reports on the entire process, from establishing the characteristics of the existing building, carrying out design simulations, documenting the off- site manufacture and on-site installation, and carrying out instrumental monitoring, occupant studies and performance evaluation. Multi-objective optimisation is used throughout the process, for establishing the characteristics of the building before the retrofit, conducting the design simulations, and evaluating the success of the completed retrofit. Building physics parameters before and after retrofit are evaluated in an innovative way through simulation of dynamic heating tests with calibrated models, and the method can be used as quality control measure in future retrofit programmes. New insights are provided into retrofit economics in the context of occupants’ health and wellbeing improvements. The wide scope of the lessons learnt can be instrumental in the creation of continuing professional development programmes, university courses, and public education that raises awareness and demand. These lessons can also be valuable for development of new funding schemes that address the outstanding challenges and the need for updating technical reference material, informing policy and building regulations.

Built environment comprises of a multitude of complex networks of buildings and processes in and between buildings. The paper looks at resilience design on three different levels: the building, the site, and the region. The building resilience design is studied using multi-objective optimization of a recently completed Passivhaus retrofit, under four different climate years: current, 2030, 2050, and 2080. The site resilience design is studied on the basis of a balance between incoming solar radiation and evaporative cooling from transpiration of plants to mitigate heat island effect. The regional resilience design is studied using a network model, taking into account connectivity, information capacity, and the ability to reconfigure. A common denominator found between these three aspects is a degree of system redundancy. Thus, a provision for adaptable building thermal insulation, a provision for adaptable green areas, and a provision for adaptable connectivity are the ingredients for resilient designs on these three respective levels. The findings increase our understanding of practical issues and implications for the resilience design of the built environment under extreme weather events. A combination of qualitative and quantitative approaches discussed in the paper provides practical guidance for designers and policy makers.

Mainstream dynamic simulation tools used by designers do not have a built-in capability to accurately simulate the effect of hemp-lime on building temperature and relative humidity. Due to the specific structure of hemp-lime, heat travels via a maze of solid branches whilst the capillary tubes absorb and release moisture. The resultant heat and moisture transfer cannot be fully represented in mainstream simulation tools, causing a significant performance gap between the simulation and the actual performance. The author has developed an analysis method, based on a numerical procedure for digital signal filtering using Fourier series. The paper develops and experimentally validates transfer functions that enhance simulation results and enable accurate representation of behaviour of buildings built from hemp-lime material using the results of a post-occupancy research project. As a performance gap between design simulation and actual buildings occurs in relation to all buildings, this method has a wider scope of application in reducing the performance gap.

This paper uses two diverging interpretations of resilience to review and assess current UK policies and guidelines for urban resilience, a term generally associated with the strength of key systems and cities and their capability to maintain functionality in the face of external shocks. Both developed in scientific studies, the first interpretation (engineering resilience) is based on a mechanistic model of systems that can recover their original state aftershocks, and the second (ecological resilience) is based on an evolutionary model enabling adaptation to disturbances. Through a literature review, practical applications to planning are discussed for each model in terms of long-term efficacy. The contribution of this paper to an understanding of urban resilience is therefore twofold. First, an identification of the long-term consequences on the built environment of the policies associated with each model is provided, with the mechanical model ultimately hindering, and the ecological model favouring, adaptation. Second, some approaches to generate effective responses to environmental and societal change are identified, together with enabling tools. Ultimately, this paper emphasizes that the idea of a resilient city is fit for this age characterized by uncertainty, although it requires the recognition within planning practice that urban adaptation cannot be attained with current methodologies, and that much can be learned from theories on the resilience of ecosystems.

Inherent to the sustainability discourse is concern about the long-term future. If sustainable, cities must deliver positive benefits over their possibly long lifetime. Yet in formulating guidance and negotiating design choices for urban development, the consideration of uncertainty and potential future adverse conditions leading to failure is difficult to deal with. In this paper an approach to this issue that can inform the planning and/or urban design process is presented. It is based on a scenario analysis methodology (futures analysis), which herein is used to appraise the energy-efficiency strategies currently recommended in the UK planning system and best practice. The built environment is one of the major consumers of energy, and its energy efficiency is thereby central to any attempt to reduce carbon dioxide emissions. Through the analysis, some important factors that could undermine good energy performance emerge. Such findings can lead to the making of decisions that can enhance urban resilience. The first part of the paper provides an overview of the energy-efficient strategies examined, as well as current approaches for considering the evolution of present conditions when planning. The second part presents the futures analysis and its significance is demonstrated through a case study. Inherent to the sustainability discourse is concern about the long-term future.

As we increasingly become aware of the causes and consequences of the climate change, there is a sense that we are dealing with an almost impossible problem to solve; that our targets for zero carbon buildings are far in the future; and that our targets are hard to achieve. This book develops a structured method for zero carbon design and demonstrates that it is perfectly possible to design new or retrofit zero carbon buildings today, using existing technologies. Dynamic simulation is an essential ingredient of this method and a pre-requisite for the level of analysis and optimization that is needed in order to achieve zero carbon design. The second essential ingredient is the economic analysis, and the book demonstrates how zero carbon designs can be optimised to result in lucrative rates of return on investment. The third essential ingredient is the achievement of thermal comfort. The book argues that zero carbon living is not about a considerable change of behaviour, but that it is about design that works with climate rather than against it, that uses predominantly passive rather than active means for achieving thermal comfort, and that is well tested, integrated and optimised using dynamic simulation. Using this method, designers can start making a difference today. This book therefore makes a case for change: a change of our perceptions that we are dealing with an impossible problem to solve, a change of our business and economic models, and a change of our attitudes towards zero carbon design and zero carbon living.

Development of the human society and its technological, economic and financial systems, coupled with the population growth, has resulted in high interconnectivity between individual and corporate entities. These entities form networks of co-dependent agents which operate under critical connectivity. Climate change has brought about an increased frequency of extreme events, such as heat waves, droughts, floods and hurricanes, which can easily set off event avalanches that propagate throughout these networks. This paper looks into event propagation characteristics of production and consumption networks and into how these characteristics can be designed and managed so as to prevent such extreme events from becoming event avalanches that sweep through the network and result in considerable human and material costs. It draws conclusions on how sustainability of an urban environment can be maintained at the time of occurrence of extreme events.

The approach to systems thinking in design in this paper is based on the concept of emergence. Historically, emergence has been at the heart of nature's designs, producing living organisms on earth for several billion years. Emergence as a process occurs in systems with a multiple number of components, in which the components follow simple individual rules, as well as interact with other components. In this paper, well-established models of design thinking will be analysed and their limitations in terms of a variety of resultant designs will be demonstrated. Subsequently, it will be demonstrated how emergence-based systems thinking opens up the scope for exploration and a range of resultant design possibilities. The current design practice explores a small number of design options for making an optimum design solution, resulting in a large number of design possibilities unexplored and in opportunities missed. The approach based on emergence integrates the systems approach into design thinking, extending the boundaries of current design practice.

Future scenarios provide challenging, plausible and relevant stories about how the future could unfold. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenarios published over the period 1997–2011 and within this research, a sub-set of >160 scenarios has been identified (and categorized) based on their narratives according to the structure first proposed by the Global Scenario Group (GSG) in 1997; three world types (Business as Usual, Barbarization, and Great Transitions) and six scenarios, two for each world type (Policy Reform—PR, Market Forces—MF, Breakdown—B, Fortress World—FW, Eco-Communalism—EC and New Sustainability Paradigm—NSP). It is suggested that four of these scenario archetypes (MF, PR, NSP and FW) are sufficiently distinct to facilitate active stakeholder engagement in futures thinking. Moreover they are accompanied by a well-established, internally consistent set of narratives that provide a deeper understanding of the key fundamental drivers (e.g., STEEP—Social, Technological, Economic, Environmental and Political) that could bring about realistic world changes through a push or a pull effect. This is testament to the original concept of the GSG scenarios and their development and refinement over a 16 year period.

The development process at the site or building scale is a multiobjective process requiring the cooperation of many professions and other stakeholders. The addition of multiple sustainability objectives, often seemingly unrelated (economic versus environmental versus social) in a rapidly changing global urban context, further constrains and complicates the process. The MODESTT mapping approach was developed to elucidate the interdependencies, tensions, and trade-offs between different sustainability objectives for a given development, and to make explicit the points at which a single design decision may ‘lock-in’ or ‘lock-out’ various possible outcomes. In this article, we review and analyse existing models of the development process, illustrate the decisions and activities inherent in delivering a single element of a development (illustrated in this paper with the example of a roof); then apply the MODESTT analysis to three sustainability objectives. The analysis makes explicit the critical importance of sequencing of actions and decisions, and interdependencies between specific objectives that lead to tensions and trade-offs between the multiple sustainability objectives. We conclude by making recommendations for the generic application of the MODESTT approach to improve sustainability throughout the site development process. Regardless of the tools that are available in the UK or elsewhere for the development process and for sustainability proxies, it is the timing and sequencing of decisions (when data are collected or the tools are applied) that are important in delivering effective solutions.
