“…Given the prevalence of energy use intensity, smaller spaces are penalized because of a higher "equipment" per floor area ratios. Contrary to current energy codes that specify performance requirements our results show great potential in savings through spatial efficiency measures, the thoughtful planning and design of buildings and with it the possibility to include spatial metric for designing of building energy sufficiency [33]. While the paper shows substantial promise for using automated floor plans for lowering building energy use, the authors acknowledge that there are important questions of ownership when using an automated procedure that is based on precedent designs.…”

Humans spend over 90% of their time in buildings which account for 40% of anthropogenic greenhouse gas (GHG) emissions, making buildings the leading cause of climate change. To incentivize more sustainable construction, building codes are used to enforce indoor comfort standards and maximum energy use. However, they currently only reward energy efficiency measures such as equipment or envelope upgrades and disregard the actual spatial configuration and usage. Using a new hypergraph model that encodes building floorplan organization and facilitates automatic geometry creation, we demonstrate that space efficiency outperforms envelope upgrades in terms of operational carbon emissions in 72%, 61% and 33% of surveyed buildings in Zurich, New York, and Singapore. Automatically generated floorplans for a case study in Zurich further increase access to daylight by up to 24%, revealing that auto-generated floorplans have the potential to improve the quality of residential spaces in terms of environmental performance and access to daylight.

“…In turn, energy demand varies based on various factors. As indicated in Guo et al (2023), the key determinants behind the building energy service demand vary on different trends in the socio-economic system, technological factors, behavioral aspects, and climate issues (Harvey, 2014;Scott et al, 2015;Scott et al, 2014;Zhou et al, 2014) and numerous electrification pathways. One key issue for limiting energy consumption regarding demand reduction concerns improving building stocks (Clift, 2007).…”

“…Given the multiple outstanding studies concerning sufficiency, efficiency, and renewables for attaining goals for reducing GHGs and energy demand, Hu et al (2023) identified a gap in achieving the Building Energy Sufficiency (BES) in the building operational phase, considering not only energy or emissions requirements but also addressing occupant demand as well. It would be useful to mention that the definition of BES varies in the relevant literature, while in the building sector, occupant demands are categorized into four categories: time and space, quality and quantity, control and adjustment, and flexibility, matching human well-being with building energy sufficiency.…”

Energy keeps the global economy alive, whereas it is extensively exposed to various climate change impacts. In this context, severe business competition (e.g., the building sector) and the unwise use of natural resources and ecosystem services (e.g., fossil fuel energy sources) seem to sharpen the relevant effects of climate change. Indicatively, contemporary issues at the interface of building energy performance and environmental quality levels include consequences from global warming, increasing releases of carbon dioxide to peak electrical loads, power grid and building planning, and energy demand and supply issues. In light of such concerns, the present review paper attempts to disclose the multifaceted and multidisciplinary character of building energy use at the interface of the economy, the environment, and society against climate change. This review highlights energy efficiency concepts, production, distribution, consumption patterns, and relevant technological improvements. Interestingly, the reviewed contributions in relevant literature reveal the need and necessity to alter the energy mix used and relevant energy use issues. These include developments in climate-proof and effective systems regarding climate change impacts and shocks. Practical implications indicate that the sustainable development goals for clean energy and climate action should be followed if we wish to bring a sustainable future closer and faster to our reality.
