Dr Marco Macagnano is Associate Director and Head of Sustainability at Bentel Associates International, Director at the Green Building Council of South Africa, and a member of the Advisory Board to the Department of Architecture at the University of Pretoria. His doctoral thesis is titled: “An integrated systems-design methodology and revised model for sustainable development for the built environment in the Information Age” 18 A building is an asset into which tremendous time and money is allocated in order that it fulfil an operational mandate that is enriching to the quality of life of its occupants and users, symbiotic with its environment (urban and natural), and financially viable to its owner. The question is: how do we do this? This requires a re-think of the goal, and of the process. Firstly, the goal of sustainable development is still a relevant one. It forces us to consider the long term implications of what we do on a multi-criteria basis. However, the triple bottom line is incomplete. Not only are the criteria too broad for adequate implementation and measurement, these were considered in an era pre- dating the Information Age. The most notable revolution of our generation that has shaped entire knowledge-based economies and societies is, as yet, under-represented in architectural and sustainable design. For this reason, the Smart City conversation has drifted away from urban planning and architecture towards the Internet of Things (IoT) retrofit to augment and enhance the redundant physical city. Architecture needs to embrace the needs of knowledge-based development as a critical criterion if our buildings are to last for generations that follow. Are our urban environments enabling knowledge-sharing (between users, between buildings, and between users and buildings) to create responsive and adaptable environments? If we begin to ask this question we find ourselves transitioning from think about buildings as products, to buildings as systems. We no longer ask ourselves if buildings are functional, but if buildings are usable. And by recognising that architecture is human- centric we begin to query the significance of an intervention on later generations. We are therefore also primed to provide our clients not only with physical assets, but information assets that are participant to the future’s Smart Cities. Secondly, an evolution of architectural process is required. As an industry that is notoriously slow to adapt (after all, BIM is already a decades-old technology) this is truly the greatest challenge. Within this evolution of process it becomes clear that an integrated approach towards systems- design is required. This achieves a number of things: a framework for rigorous testing and simulation (enabled through computational design and Artificial Intelligence), knowledge feedback loops and, importantly, the integration of various tools and ratings systems to interrogate the architectural solution according to multiple criteria. Is sustainable development still relevant? I think it is. However it could be that our predisposition to simplify it or even venture into the discovery of alternatives resulted from the fact that we haven’t taken the time to recognise it as a concept that requires industry focus and customisation. Ultimately, this remains in the aim of realising architectural solutions that meet the needs of future generations within ecological constraints. Sustainable Development in Architecture
