Special Issue Information

Dear Colleagues,

Buildings are massively complex systems, and their operation contributes to nearly 30% of carbon dioxide emissions worldwide. They are designed using dynamic simulation tools, which are in the background, typically based on top-down systems of equations that need to be simplified in order to be solved. This causes significant discrepancies between the designed and actual performance, a so called “performance gap”, leading to sub-optimum solutions. In these traditional approaches to building simulation, the problem is brought closer to the solution method, instead of the solution method being brought closer to the problem. We therefore may be partially “blinded” by these traditional approaches, which stand as an artificial interface between nature and our understanding of nature. But as buildings do not solve systems of equations in order to “know” how to transfer heat within them, why would we? Heat transfer occurs through proximity interaction between molecules, leading to self-organised behaviour that is much faster and more complex than the behaviour modelled by the top-down systems of equations. This Special Issue of Sustainability seeks to consolidate the alternative bottom-up self-organised simulation methods that are more direct representations of the actual physical processes, rather than the indirect mathematical descriptions of these processes that partially remove certain aspects of the natural behaviour. Articles on emergence-based approaches to the self-organised simulation of heat and moisture transfer, air flow, energy performance, carbon emissions, building form creation, and other relevant processes for sustainable building design are invited for consideration and peer-review for this Special Issue.

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. Full article

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.

This paper presents and discusses an optimisation approach applied to spatial layouts in care home building design. With this study, we introduce a method for increasing the floor plan efficiency using a self-organising genetic algorithm, thus reducing energy consumption, improving the wellbeing of residents and having an implicit impact on the costs of energy and health care. In order to find an optimal spatial configuration, we elaborated and tested a number of design criteria based on existing literature reviews and interpreted through initial considerations of care home layouts. These are used as objectives in a Genetic Algorithm (GA) to evaluate the best design solution. The self-organised floor plan is then used to run a final simulation to observe how residents could use the optimised spaces and to measure the improved efficiency of the new plans. The paper concludes with the discussion of the results and some considerations for future studies and experiments using emergence behaviour models to improve sustainable development in design.
