But Estonian company <a href=\"https:\/\/r8tech.io\/\" target=\"_blank\" rel=\"noopener\">R8 Technologies<\/a> has taken a different path. Their virtual assistant Jenny autonomously manages the indoor climate of office buildings around the clock \u2013 saving energy and preventing system failures in the process.<\/p>\r\n<p class=\"\" data-start=\"391\" data-end=\"714\">According to Siim T\u00e4kker, founder of R8 Technologies and an alumnus of TalTech, the solution is based on machine learning that adapts to a building\u2019s behavior and the surrounding environment. Jenny continuously collects data from thousands of points \u2013 from temperature and humidity to electricity prices and human movement.<\/p>\r\n<p class=\"\" data-start=\"716\" data-end=\"1086\">T\u00e4kker explained that the workload involved in managing building climates has exceeded human capabilities: \u201cIn the past, you\u2019d look at a few dozen sensor points and decide what to change in the system. Now, the number of data points reaches into the hundreds of thousands.

For many, the idea of a virtual assistant seemed far-fetched, and the company often had to explain why such a solution was even needed.<\/p>\r\n<p class=\"\" data-start=\"1403\" data-end=\"1663\">Today, R8 Technologies operates in 23 countries, and its system has been translated into more than fifteen languages \u2013 a reflection of Estonia\u2019s flexibility and adaptability despite its small size. Still, international expansion hasn\u2019t come without challenges.<\/p>\r\n<p class=\"\" data-start=\"1665\" data-end=\"1992\">T\u00e4kker recalls that after Russia launched its full-scale war, working with partners outside Eastern Europe became more difficult. \u201cI remember when the war started, we hit a kind of wall \u2013 an Estonian company, close to the border. People asked whether we could be trusted, whether we\u2019d even still exist tomorrow,\u201d he recalled.<\/p>\r\n<p class=\"\" data-start=\"1994\" data-end=\"2313\">He added that such moments require the ability to speak the local language and explain that Tallinn is a safe, modern, and rapidly developing city, where technologies used across Europe are born. \u201cWe also made technical upgrades, obtained various certifications, and set up a data center in Western Europe,\u201d he added.<\/p>\r\n<p class=\"\" data-start=\"2315\" data-end=\"2446\">Knowing the local language also helps, especially when technical details need to be explained to earn clients\u2019 and partners\u2019 trust.<\/p>","image":null,"align":""},{"acf_fc_layout":"image","image":12819},{"acf_fc_layout":"text","type":"text","text":"<h4 data-start=\"61\" data-end=\"106\">R8 Jenny \u2013 the colleague who never sleeps<\/h4>\r\n<p class=\"\" data-start=\"108\" data-end=\"531\">The virtual assistant Jenny is more than just software \u2013 she\u2019s like a member of the team. She understands the logic of the building, adapts to usage patterns, and can anticipate problems before they affect users. \u201cThe worst situations are when both heating and cooling are running in the same room at the same time, and ventilation adds to the chaos,\u201d said T\u00e4kker, describing the kind of scenarios Jenny helps to prevent.<\/p>\r\n\r\n<blockquote>\r\n<p class=\"\" style=\"text-align: center;\" data-start=\"533\" data-end=\"673\">\"The worst situations are when both heating and cooling are running in the same room at the same time, and ventilation adds to the chaos.\"<\/p>\r\n<\/blockquote>\r\n<p class=\"\" data-start=\"675\" data-end=\"900\">The system takes into account dozens of variables: electricity prices, sunlight, weather conditions, the nature of workdays, past usage patterns, and much more. Decisions are made transparently and rationally \u2013 not at random.<\/p>\r\n<p class=\"\" data-start=\"902\" data-end=\"1050\">According to T\u00e4kker, Jenny makes considered decisions based on knowledge of the building\u2019s behavior and domain expertise \u2013 not on vague assumptions.<\/p>\r\n<p class=\"\" data-start=\"1052\" data-end=\"1516\">Human habits also play a significant role in indoor climate. T\u00e4kker notes that the problem often lies not in the technical systems but in the expectations of the room\u2019s occupants. If someone wants to wear a T-shirt in the office during winter, the room temperature is set too high, leading to increased energy consumption. A smarter choice would be to wear a sweater and maintain a temperature of around 21\u201322 degrees Celsius, which is also in line with standards.<\/p>\r\n<p class=\"\" data-start=\"1518\" data-end=\"1841\">The system can take subjective preferences into account. If one team prefers cooler air and another prefers it warmer, Jenny adjusts accordingly. When the occupants change or the weather shifts, the operating mode changes as well. The system also detects if devices are out of sync and provides maintenance recommendations.<\/p>","image":null,"align":""},{"acf_fc_layout":"image","image":12817},{"acf_fc_layout":"text","type":"text","text":"<h4 data-start=\"71\" data-end=\"130\">A look into the future: more transparency, more purpose<\/h4>\r\n<p class=\"\" data-start=\"132\" data-end=\"576\">According to T\u00e4kker, Estonia is technologically strong, though not necessarily ahead of other countries. Our competitive edge lies more in flexibility and the ability to quickly test and implement science-based ideas in real business environments. In his view, it\u2019s the practical collaboration between researchers and entrepreneurs that enables Estonia to develop solutions that don\u2019t remain theoretical but make it to real life and the market.<\/p>\r\n<p class=\"\" data-start=\"578\" data-end=\"1056\">That\u2019s why R8 Technologies works closely with TalTech. Joint projects involve, for instance, evaluating the efficiency of ventilation systems or optimizing fan operations. Many PhD and master\u2019s students who started with research projects have later joined the company as full-time employees. T\u00e4kker highlights TalTech senior researcher <a href=\"https:\/\/trialoog.taltech.ee\/taltechi-teadur-tuule-mall-parts-palvis-noore-inseneri-preemia\/\" target=\"_blank\" rel=\"noopener\">Tuule Mall Parts<\/a> as one example \u2013 she received the Young Engineer Award from President Karis and now contributes directly to R8\u2019s development.<\/p>\r\n<p class=\"\" data-start=\"1058\" data-end=\"1345\">T\u00e4kker sees the future direction as multi-layered. On the one hand, building management is clearly moving toward greater integration of data systems \u2013 different data sources that currently operate in parallel or with partial overlap will increasingly interact and complement one another.<\/p>\r\n<p class=\"\" data-start=\"1347\" data-end=\"1722\">On the other hand, it is becoming crucial that all automated decisions are understandable to both technical staff and everyday building users. \u201cIf the system makes a decision but no one understands why that decision was made, then trust cannot develop,\u201d said T\u00e4kker. That\u2019s why it's not enough for AI to efficiently manage a building \u2013 its actions must also be explainable.<\/p>\r\n\r\n<blockquote>\r\n<p class=\"\" style=\"text-align: center;\" data-start=\"1724\" data-end=\"1836\">\"If the system makes a decision but no one understands why that decision was made, then trust cannot develop.\"<\/p>\r\n<\/blockquote>\r\n<p class=\"\" data-start=\"1838\" data-end=\"2192\">In a broader perspective, T\u00e4kker sees AI moving increasingly toward hybrid solutions, where automation and human oversight don\u2019t exclude but rather support one another. AI doesn\u2019t need to replace humans \u2013 it should relieve them of routine burdens and allow them to focus on tasks that require human judgment, ethical consideration, or strategic thinking.<\/p>\r\n<p class=\"\" data-start=\"2194\" data-end=\"2602\">T\u00e4kker also believes that AI\u2019s role goes beyond optimization and control \u2013 its ability to support decision-making in complex and rapidly changing environments is becoming more important. For example, in the face of energy price volatility or disruptions in supply chains, smart systems capable of rapid adaptation will, in his view, shape the future of building management \u2013 and even urban planning at large.<\/p>\r\n<p data-start=\"2194\" data-end=\"2602\">**<\/p>\r\n<p class=\"\" data-start=\"2609\" data-end=\"2854\"><em>R8 Technologies received recognition at <a href=\"https:\/\/trialoog.taltech.ee\/365-paeva-355-lugu-trialoog-tahistas-esimest-sunnipaeva\/\" target=\"_blank\" rel=\"noopener\">Trialoog\u2019s first anniversary event<\/a> in the category \u201cRole Model of the Year\u201d \u2013 an award highlighting outstanding examples of scientific collaboration and the promotion of science-based entrepreneurship.<\/em><\/p>","image":null,"align":""}],"related_authors":[{"author":7990,"position":"Trialoog editor"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) -
