Global warming means that heatwaves are becoming ever-more frequent. Now, we are in a global race against the clock to reduce the energy use and carbon footprint of buildings by 2050. This has highlighted the importance of making the thermal comfort of buildings a strategic and economic priority, the EPFL<\/a> writes. Personalized thermal air conditioning is the focus of Dolaana Khovalyg’s research. She is a tenure track assistant professor at EPFL\u2019s School of Architecture, Civil and Environmental Engineering (ENAC)<\/a> and head of the Laboratory of Integrated Comfort Engineering<\/a> (ICE). <\/p>\n\n\n\n

Khovalyg highlights the advantages of providing personalized thermal air conditioning and heating for each office desk, as opposed to maintaining a standard temperature throughout an open space. Her team came to this conclusion after the human thermo-physiological data that they collected showed that individuals display very different levels of thermal comfort under normal office conditions. The researchers took a cross-disciplinary approach. They combined applied engineering know-how and knowledge of human physiology in the study of the interaction between humans and buildings.<\/p>\n\n\n

France revives itself through hydrogen and less impactful buildings<\/div>

\nOver half of the \u20ac40 billion cake France is receiving from the European Commission is for climate targets. The energy efficiency of buildings, hydrogen, and green mobility are the leading priorities being subsidized through this budget.<\/div><\/div><\/div>\n\n\n

Major variations in energy expenditure<\/h2>\n\n\n\n

The researchers analyzed the energy expenditure of six individuals, comprising a non-biased sample of ordinary people that could be sharing the same office space. Over three months, this group participated in a series of experiments in a special climate-controlled chamber at ICE\u2019s lab in Fribourg in Switzerland. They carried out everyday activities such as sitting, standing and eating meals. <\/p>\n\n\n\n

Studies that measure people\u2019s energy expenditure tend to usually focus on extreme situations; they look at athletes and military staff, for instance. The energy expenditure of the average office worker is rarely studied. The researchers found significant differences between individuals, including between two men of similar build doing exactly the same office tasks. <\/p>\n\n\n\n

An ethical challenge<\/h2>\n\n\n\n

The ability to accurately measure an individual\u2019s energy expenditure paves the way for a new type of technology. The collected data are fed into the central heating and cooling systems. This enables them to adjust the temperature in a given area in real-time, and to optimize a building\u2019s power consumption. For now, heated and cooled office setups usually have a limited range of temperature settings. But this technology will make it possible to customize the temperature for each office worker.<\/p>\n\n\n\n

Ethics is amongst the main challenges with this kind of research, and issues \u2013 such as how to handle personal data \u2013 still need to be resolved. One option currently is to use non-invasive measuring devices that do not actually store any personal data.<\/p>\n\n\n

Start-up creates digital infrastructure for heating networks of the future<\/div>
In a decentralized energy market, individuals themselves produce the energy they need. The start-up Arteria Technologies is pushing for this development by providing the digital infrastructure for the heating networks of the future.<\/div><\/div><\/div>","protected":false},"author":2490,"featured_media":516277,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[42],"tags":[37531,28966,79827,128176],"location":[52892],"internal_archives":[],"class_list":["post-387975","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-sustainability-nl","tag-airconditioning","tag-climate","tag-heatwaves","tag-personalized-thermal-conditioning","location-switzerland"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/05\/vlad-b-NG9fKn8I6rc-unsplash-scaled.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/polya-plamenova-pencheva\/","display_name":"Polya Pencheva"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on July 22, 2022","modified":"Updated on July 22, 2022"},"absolute_dates_time":{"created":"Posted on July 22, 2022 1:27 pm","modified":"Updated on July 22, 2022 1:27 pm"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Sustainability<\/a>"],"unlinked":["Sustainability<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["airconditioning<\/a>","climate<\/a>","heatwaves<\/a>","personalized thermal conditioning<\/a>"],"unlinked":["airconditioning<\/span>","climate<\/span>","heatwaves<\/span>","personalized thermal conditioning<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_62d94017337c2<\/a>"],"unlinked":["pll_62d94017337c2<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Switzerland<\/a>"],"unlinked":["Switzerland<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/387975","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2490"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/516277"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=387975"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=387975"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=387975"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=387975"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=387975"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
