A “Well & Green” Approach to A Sustainable and Resilient Educational Campus
The 2020 Global Status Report for Buildings and Construction by the GABC, launched in December of 2020, noted that “While the total final energy consumption of the global buildings sector remained at the same level in 2019 compared to the previous year, CO2 emissions from the operation of buildings have increased to their highest level yet at around 10 GtCO2, or 28% of total global energy-related CO2 emissions. With the inclusion of emissions from the buildings construction industry, this share increases to 38% of total global energy-related CO2 emissions”.
This statistic reveals to us that the marginal incremental gains made through so-called green building design are totally offset by building operation, most likely from a growing plethora of technologies that we introduce into our new buildings, as well as the constantly decreasing operational efficiency of our existing and aging building stock.
This lecture will attempt to address these challenges and offer some insights into practical implementation of effective design solutions using the School of Design and Environment academic buildings as demonstrative case studies. Two key takeaways to note are: (1) we need to be much more aggressive in targeting for net-zero energy buildings at scale (2) we have to genuinely embrace a people-centric approach and sustaining a symbiotic relationship between the natural and the built environment to enhance their well-being and overall quality of life.

Quo Vadis Building Simulation – New Generation Computational Tools that Integrate Design and Operation
Due to demands caused by climate change, the energy sector is undergoing a rapid transition. Energy systems for buildings and communities need to become decarbonized, grid-responsive, resilient, and adaptive to changes in usage, technology options, and markets. This leads to increased complexity in their design and operation. Fortunately, new energy systems provide an opportunity to integrate and optimize renewables and storage across multiple prosumers and energy carriers. New system architectures and control challenges emerge, as do new requirements on design flows that can manage the increased complexity. After laying out these challenges, we will present recent progress on new generation computational tools for building and district energy and control systems. We will also present new tool chains that allow for rapid system-level prototyping, model-based design flow and digitization, ranging from design to installation and operation. We will close with a discussion about what foundation our community should build to meet design and operation challenges of new energy systems.

Radiant Indoors – Bridging Research and Practice
Natural light greatly impacts how a building is experienced by its occupants. It affects their well-being, notably from their health and biological clock perspectives, but also their perceived visual and thermal comfort, or their emotional response. If we want to support the design of places of delightful – and daylightful – living, we must bring these multifaceted considerations to become integral drivers of the creative process.
This lecture will explore current research efforts aiming towards a deeper integration of daylighting performance and indoor comfort in design, by reaching out to various fields of science, from chronobiology and neuroscience to psychophysics and computer graphics. It will also provide an example of how human-centered daylighting design can be supported by research outcomes to build a well-informed, evidence-based dialogue between specialists and practitioners.
Anne Beim on “Real Possibilities and Possible Realities: Absolute Sustainable Architecture, Materials and Tectonics”
April 22, 2021 at 12:00 pm ET | Zoom
Anne Beim is a Professor of Architecture at the Royal Danish Academy School of Architecture. She holds a MArch and a PhD in architecture from the Royal Danish Academy School of Architecture. Since 2004, she has been Chair of CINARK – Centre for Industrialized Architecture – a research center that works across the gap between architectural education, the construction industry, and the architectural profession. Since 2014, she has co-chaired the graduate program SET – Settlement, Ecology and Tectonics. From 2013 -2019, Professor Beim was chairman of the Danish Architectural Association’s Admissions Council, and from 2008-2010 she chaired the Architectural Committee for the Danish Art Foundation. Presently, she is a member of the Executive Council of the International Association of Structures and Architecture (IASA). She has also authored/co-authored multiple books: Circular Construction: Materials, Architecture & Tectonics (2019), Sustainability in Scandinavia: Architectural Design and Planning (2018), Towards an Ecology of Tectonics – The Need for Rethinking Construction in Architecture (2015), Building with an eye for the Future: Visions in Industrial Housing 1970 – 2011 (2012), Three Ways to Assembling a House (2009), Tectonic Visions in Architecture (2004), and Ecology & Architecture Quality (2002).
Real Possibilities and Possible Realities: Absolute Sustainable Architecture, Materials and Tectonics
The latest reports from UNEP, IEA and WWF point out that Man’s exploitation of nature’s resources, high emissions of greenhouse gases (GHG) into the atmosphere and worldwide waste streams have resulted in ecological systems out of balance when looking at the carrying capacity of the Earth. In this context, buildings and the construction sector are responsible for almost 40% of energy- and process-related emissions as well as the consumption of 40% of material resources (UNEP et al., 2019).
Thus, the ecological crisis calls for self-examination in the professional part of the construction sector, but also in academia amongst researchers and educators of architecture, planning and engineering. We are in a state of emergency and a growing number of experts proclaim that we have to act now, that we have to consider all potential solutions, and that the most effective ones must be implemented. This situation opens up new ways of conceiving architecture and tectonic building cultures that contain radically different solutions than those applied in present-day architecture and construction. In this talk, Professor Anne Beim will present a series of physical prototypes where absolute sustainable scenarios have been tested, resulting in new approaches to materials, construction techniques and how buildings are conceived and designed from a lifecycle perspective.
Darren Robinson on “Multiscale Simulation of Buildings as Complex Sociotechnical Systems“
April 1, 2021 at 1:00 pm | Zoom
Professor Darren Robinson is Chair in Architectural and Urban Sciences at the Sheffield School of Architecture, where he is Director of Research. His personal research activities lie at the intersection between social physics (people), building physics (buildings), and urban physics (city). Professor Robinson is particularly known for his work on the stochastic modeling of building occupants’ activities, their dependent behaviors and the impacts of these behaviors on their comfort, the integration of these models in a multi-agent stochastic simulation (MASS) platform, and on urban energy microsimulation (CitySim and SUNtool). Darren has recently worked on the convergence of these interests through co-simulation (FMI) and distributed simulation (HLA) and on the upscaling of building simulation to investigate national building stock decarbonization strategies (EnHub). He has over 100 refereed scientific publications to his credit, including the book “Computer modeling for sustainable urban design.” He is a recipient of the CIBSE Napier-Shaw Medal (2007), the FWO King Albert 1st Medal (2020), the JPBS Best Paper Prize (2010/11), the BAE Best Paper Award (2009, 2010), and the Sustainability Science Most Outstanding Article Award (2019).
Multiscale Simulation of Buildings as Complex Sociotechnical Systems
Over the past half a century, researchers have been working to improve the scope and rigor with which building performance is simulated. There are now highly sophisticated single-building simulators and increasingly sophisticated ecosystems of simulator that support urban-scale energy and environmental simulation. Efforts are also underway to dynamically simulate the energy performance of regional and national building stocks. But as the climate emergency becomes ever more pressing, so too does the need to include people in the loop; not just to consider their dynamic operational behaviors – how they interact with the building envelope and systems – but also, indeed much more importantly, to represent their decisions to invest in decarbonization investments. This is mission-critical if we are to develop robust policy measures to decarbonize our building stocks, which are responsible for around two-fifths of global CO2 emissions. In this talk, Professor Robinson will describe recent progress that has been made to increase the scope and scale of building energy simulation, with a particular emphasis on putting people in the loop to improve simulation rigor and support evidence-based decarbonization policy formulation.
