Meet CosyOS:
The First Nervous System for Buildings

We spend our whole lives in buildings, and they are broken. Think about the last heatwave. The office, the restaurant, the hotel room: all of them freezing. You complained, and nothing changed, because an operator was chasing faulty equipment they could not even find. Meanwhile, the building wasted energy and emitted carbon while the grid struggled with air conditioners and data centres. Buildings account for 30% of global energy consumption.

These situations make no sense. They come from a lack of information, digitalisation, and automation. Buildings are like old computers: under-digitised, frozen in a pre-API era, locked behind closed protocols.

Our latest innovation is a hardware-agnostic autonomous nervous system for buildings. It took two years of R&D and five PhDs to bring frontier physical AI into action. We call it CosyOS, and we gave it a voice:

Memory: CosyOS remembers how every piece of equipment actually behaves, and keeps maintenance and compliance records in order. Intelligence: it decides what should happen next. Control: it acts on its own, in real time. When it cannot act, it calls an operator by text or phone.

Installation takes less than a day, with no disruption. It plugs into any BMS-connected equipment or stranded asset. No rip-and-replace, no rewiring. It feels like installing a new operating system on a laptop, because CosyOS combines a universal knowledge graph with countless closed-protocol drivers.

The knowledge graph is how it understands a building: layout, equipment, full history. It finds compliance records and answers any question about them. We are now beta testing live calls to contractors, guiding them to the equipment that needs repair with natural speech, verifying the work and updating the records. All autonomously.

The drivers are how it acts. CosyOS already adjusts HVAC, chillers, boilers, lighting and other electrical equipment across client sites. It acts directly on stranded assets or by writing changes to BMS points. Compliance guardrails, occupant needs, and efficiency are always taken into account before any parameter changes. Legacy equipment is no barrier: specialised controllers digitalise its signals, existing sensors do the rest. If required, wireless sensors fill the gaps.

CosyOS was born to make building operations autonomous. Where there is a facility management team, it augments them. For mid-sized buildings, it becomes the first-aid digital facility manager a regional manager never had. Our automated IPMVP module has verified 27-38% savings on HVAC across clients and we are now expanding CosyOS capabilities to the next level so it can take care of one whole building or a whole portfolio, spotting patterns no site manager could ever see alone.

Cars were manual, then automatic, and now they drive themselves. The built environment is next. CosyOS is now live to make this a reality in your building.

Energy Efficiency Is a Cost and Compliance Mandate.
Why Energy Management Systems Are Now Essential

Heating, ventilation and air conditioning (HVAC) is the largest operating expense in most commercial buildings, yet many assets still rely on outdated controls. Bill Gates has warned that cooling demand could increase tenfold by 2050. Corporate buildings face a costly scenario unless they hear PWC: energy demand is profitable now, a compliance requirement, and supports climate goals. The question is no longer whether to optimise energy use, but how quickly organisations act to protect margins and remain compliant.

The most cost-effective and scalable solution for reducing emissions from buildings is not to replace HVAC systems. It’s to make their operation smarter. That’s exactly what Energy Management Systems (EMS) do—and they’re no longer optional.

In the UK, by 2030 all leased commercial buildings must achieve at least an EPC B rating under the Minimum Energy Efficiency Standards (MEES), and TM44 inspections for HVAC efficiency are tightening. In the EU, the updated Energy Performance of Buildings Directive (EPBD) will require automation and control systems in non-residential buildings with HVAC outputs above 290kW by 2025. In short, buildings that don’t manage energy actively will no longer be legally lettable.

Yet most of the UK’s 2 million non-domestic buildings still rely on outdated or minimal controls. Many buildings already have a Building Management System (BMS), but this is not enough because their primary concern is monitoring, basic control, and integration as per ISO 16484 standard. Once they are commissioned, they are rarely re-optimised and run on fixed schedules and static setpoints. In other words, they are not responsible for optimising building operations.

An Energy Management System (EMS) focuses on data-driven automation, predictive analytics, and dynamic control to cut energy use, emissions, and costs in real time. An EMS constantly improves building performance, delivering 20-40% savings. It can support fault detection and diagnostics, and it is an integral part of a continuous improvement strategy. Where a BMS is the reactive control infrastructure, an EMS is a strategic and predictive intelligence layer.

According to ISO 52120 and the latest BCIA report, EMS systems are ranked from Class D (manual or no control) to Class A (fully automated, optimised, and interconnected). A Class A EMS includes:

Compared to technologies like heat pumps or solar PV, Class A EMS offers superior carbon reduction potential per pound invested—cutting emissions at just £224/tonne of CO₂.Many traditional EMS products on the market today only meet basic or Class C requirements, typically offering:

These features are helpful—but insufficient for compliance, let alone deep decarbonisation. In contrast, advanced EMS platforms like Cosysense, can exceed Class A performance while delivering far more value.

Cosysense is the first EMS to combine Class A automation with human-centric analytics with early fault detection. While most systems respond to presence, we go further—monitoring comfort and air quality levels combined with usage patterns. Moreover, Cosysense keeps on extending its features and has a very exciting tech roadmap ahead. This matters because it unlocks deeper energy savings with better user experience:

For asset owners and occupiers, that means lower operating costs, better compliance scores, and more satisfied tenants. A building that doesn’t comply with MEES, TM44, or EPC B won’t be lettable. And a building that isn’t smart enough to adapt to climate change will be expensive to operate. EMS is no longer a nice-to-have. It’s an essential infrastructure required for compliance.

Zoning explained: Cosysense value beyond it

Zoning boosts heating, ventilation, and cooling systems (HVACs) efficiency. It's not a new trick, but it sure cuts down on your bills and gives you more control over your indoor climate. Discover why zoning matters and when it's best to use it. Moreover, we'll show how Cosysense ramps up your HVAC's efficiency, with or without zoning.

Zoning is important for multi-level buildings, spaces with high ceilings or multiple windows with uneven sun exposure. You should consider zoning if you consistently find that the temperature in your space varies greatly or if you constantly have unoccupied areas. Smart Zoning brings the traditional concept to a new era. A control board is responsible for synchronising smart thermostats that define indoor conditions in each zone. They use dampers to control the airflow throughout the building’s ductwork (i.e., tubes that distribute the air). Smart venting works similarly but uses different software and hardware. It also creates zones, but instead of using dampers inside ducts, the airflow is controlled by supply vents. The advantage of smart vents is that they typically reduce installation costs and time, and no changes in the existing ductwork are typically required.Although smart zoning and venting boost efficiency, you should also consider their potential disadvantages. Your HVAC needs to be dual-stage or modulating for zoning, or you may need a new one. HomeAdvisor says you are looking at ~$3,000 for mini-splits and up to $7,000 for more complex HVACs. Even if you have the right HVAC, the upfront cost of smart zoning or venting is between $1,700 and $4,500 without considering the new HVAC components you may need. In addition, your ductwork size, configuration, and connections should allow optimal airflow variation. Otherwise, you may be facing considerably high retrofit costs. According to the US Department of Energy, HVAC zoning/venting can reduce by 30% energy costs and take over 5 years to pay itself, depending on the increased complexity and costs of the HVAC maintenance.How is Cosysense different?
With smart zoning or vents, occupants can control the temperature in each zone better. This saves energy, but it does not assure occupants’ comfort. We all have different comfort levels, and finding that sweet comfort spot in communal spaces is hard. Think about your office: How often have you participated in or witnessed a fight over an HVAC remote control in the workplace? The result is that common spaces are typically overcooled or overheated, wasting energy owing to discomfort.
Cosysense is a simple add-on for comfort and energy savings with no installation costs. We differ from zoning or smart venting because we optimise comfort in communal spaces to generate energy savings. Our system works in each zone independently and can be coupled with smart zoning, smart vents, central air conditioning, heat pump or ductless systems. We can also install our system in single spaces, so there is no need for complex HVACs for our solution to work. Moreover, our human-centred efficiency solution quantifies your scope 2 emissions. Do you want to test it? Cosysense is free to install and will only cost you a fraction of your savings.

Cutting costs and emissions:
A dive into HVAC efficiency

Heating, ventilation, and air conditioning systems (HVACs) account for 38 to 40% of electricity consumption in office buildings, representing 70% of base building landlord costs. With increasing electricity prices and greenhouse emissions regulations, HVAC energy efficiency matters more than ever for commercial buildings. What can you do about it?HVACs' most important function is to promote indoor comfort and well-being. Many businesses use smart thermostats like Nest, Ecobee, and Pelican to control and manage HVACs more efficiently. These thermostats adjust your HVAC’s temperature by learning about your behaviours, preferences, weather data, and your space’s characteristics. They also adapt temperature settings when there are no occupants and can optimise compressor and ventilation settings to minimise power consumption. They can also provide reminders to change filters and integrate them into other smart systems.The issue with smart thermostats is that they are limited to certain types of HVACs, require WiFi, and often need a retrofit for installation quote. In addition, they were developed to cater for homes with few occupants. This means they estimate comfort rather than quantify it.

Occupants too hot or too cold due to wrongly set HVACs in the workplace affect more than half of the US and UK occupants. It leads to an astonishing 2% to 15% energy waste per degree of discomfort energy waste per degree of discomfort, reduced productivity, and increased complaint rates.Cosysense is unique because we monitor occupants' comfort (among other variables) to leverage the latest AI for HVAC energy efficiency. Thanks to our solution, comfort goes hand in hand with efficiency. We are also different because our solution has no upfront cost. We are committed to reducing your consumption, so we only charge a fraction of your realised savings.The critical role of HVACs on buildings’ comfort and well-being will only increase due to extreme weather conditions caused by climate change. They are the largest source of energy consumption and emissions of buildings, so every efficiency effort matters. We can support you in transforming your space into a more efficient, sustainable and comfortable venue without any hassles, changes to your existing systems or cost.

Chill out, but not too much:
health impacts of air conditioning

Have you ever felt sick after spending time in an air-conditioned space? Have you blamed the air conditioner for your sickness? You are not alone. ACs are key for a healthy and cosy indoor environment, but overcooling impacts our health and well-being. Here is how.Maintaining a comfortable temperature and the right humidity is key for promoting a healthy environment in offices and other indoor spaces. Low temperatures can reduce the growth of bacteria and other potential allergens. However, we are we are overcooling shared spaces. Exposure to cold air for extended periods can lead to breathing discomfort due to irritation and inflammation of the airways. The respiratory system constricts, making individuals more prone to respiratory infections and can provoke asthma in susceptible individuals.

The right humidity levels also matter for a healthy environment. Mould forms at a relative humidity of more than 70% and once it forms, it costs a lot of money to retrofit buildings to remove it. Mould can lead to allergic reactions such as sneezing, running nose, red eyes and skin rash. It can also cause asthma attacks. Air conditioning systems deplete humidity levels in indoor environments, leading to dry air which is needed to avoid mold formation. However, overusing the AC means the air is dehumidified to an extent that can cause skin dryness, itching, and irritation. As with temperature, balance is critical to keep humidity at healthy levels between 40% and 60%.Indoor life without air conditioning is unimaginable. With climate change and rising heat waves, we will only depend more on ACs for healthy and cosy indoors. The key is to find the right balance on how to use it, which needs monitoring technology. That is why Cosysense exists. We are creating smart, healthy, and comfortable commercial spaces for everyone, which also brings a reduced carbon footprint. We use state-of-the-art sensors and artificial intelligence technology to make it happen. Would you like to learn more about our technology? Reach out. You can test our technology for free and keep it by paying only a fraction of your monthly energy savings.

Thermal inequality: millions of women and our planet suffer from it every day

How often have you been freezing in an overly air-conditioned office during summer or boiling during winter? If your answer is 'countless', then you're not alone. Most females and other temperature-sensitive individuals depending on age, metabolic rate, and ethnicity, suffer from thermal discomfort. This is likely the largest gender inequality you have never heard of. Addressing this issue is crucial for creating more inclusive commercial buildings, boosting company productivity, and promoting sustainability.The uncomfortable reality is that 4 to 8 out of ten people today suffer from thermal discomfort. An occupant survey conducted in over 400 offices revealed that overcooling was 1.8 times more likely to affect women than men, which is aligned to complaints about cold offices shared more often by women on social media.

Two main approaches determine AC settings. The first relies on international standards or government recommendations designed primarily with male comfort parameters in mind. These standards often overestimate women's metabolic rates, incorrectly assuming that women will be comfortable at lower temperatures than is actually the case. The second approach depends on the individual manager's temperature preference, with AC settings based on personal comfort. Considering that most leadership positions today are occupied by men, gender thermal discrimination is perpetuated.Thermal discomfort significantly impacts companies’ productivity. For instance, a 10-degree temperature change decreases women's scores in verbal and math tests by 27%. Addressing gender thermal discomfort is also crucial for sustainability. Air conditioning will contribute to 18% of greenhouse gas emissions by 2050. Every degree of overcooling or overheating means an excess energy consumption of 2 to 15%, leading to increased emissions. Hence, adjusting the AC settings to cater to all genders can significantly reduce energy usage and greenhouse emissions.Gender thermal discomfort is a prevalent issue with far-reaching implications. It not only perpetuates gender bias but also impacts productivity and pollutes. Addressing this issue calls for re-evaluating existing standards and new user-centred solutions that consider all genders for determining wellbeing. Indeed, this is exactly what we do in Cosysense because we care about all genders’ wellbeing and the environment. With our smart sensors and AI technology, commercial buildings become more inclusive for everyone. They improve people’s productivity, cut energy bills and reduce their emissions. It is time for comfort to meet sustainability.

Cosysense: making shared spaces
pleasant and energy efficient

Who hasn't lived or seen the typical arguments over cold or hot offices? We all know it. For buildings, discomfort means up to 15% excess energy consumption and greenhouse gas emissions for each degree outside optimal heating or cooling systems. The boom in heating, ventilation, and air conditioning (HVAC) will result in 18% of global greenhouse emissions by 2050. The changing climate is accelerating this trend at the moment with a boom of installations in workplace, retail, and hospitality buildings. Are we making good use of AC that justifies paying high electricity bills and greenhouse gas emissions? The answer is no.Most shared spaces set a constant AC temperature of 18 or 21 ºC regardless of who is inside, the outside weather, or the current electricity rate. Interestingly, we found that over 54% of people in shared spaces freeze. You might have been feeling cold yourself sometimes. Check #coldoffice on X or TikTok to learn about the magnitude of this problem.

Our approach to HVAC is revolutionary. We prioritise comfort and health in communal spaces of commercial buildings to enhance people's well-being and productivity. Our plug-and-play sensors collect user comfort data, indoor environment, and HVAC power that we transform into real-time CO2e emissions. Our AI model uses the data for dynamic comfort and energy optimisation. By making occupants comfortable, we cut 15% to 30% of electricity costs and emissions for buildings. For example, in a London coworking space, we generated 897kWh savings (~£296 and 201kgCO2e) for one HVAC in 30 days. We are a cleantech company, so we align our revenue with our promise. Clients have zero installation costs. They subscribe to our solution with a guarantee: they only pay if we generate larger savings than our fee.We are the first human-centred energy efficiency company in the world. We will transform 1 million buildings by making people comfortable, cutting the equivalent greenhouse gas emissions as if we were creating a new forest as big as London every single once reaching scale.

Our customers are businesses, such as multi-site restaurant, hospitality, and commercial property operators.In order to provide our services, to manage our relationships with customers, suppliers and partners, to recruit, and to generally run our business, we need to process personal data. When we do so, we act as a controller of that personal data, which means we are responsible for processing it in compliance with UK data protection laws: the UK GDPR and the Data Protection Act 2018 (together, the "Data Protection Legislation").We act as a controller when we collect personal data belonging to: visitors to our website; prospective customers; individuals who work for our customers, suppliers and business partners; job candidates; and individual contacts we engage with in the course of business.Cosysense Ltd is registered in England and Wales under company number Cosysense Ltd, with its registered office at 5 Brayford Square, E1 0SG London. We are registered with the Information Commissioner's Office (ICO) under registration number C2007325.Building occupants: where our systems process data collected by sensors installed in our customers' buildings (see section 7), we generally act as a processor on behalf of the relevant building operator, who remains the controller of any personal data involved. If you are an occupant or visitor of a building where our technology is deployed, and you have questions about how your data is handled, please contact the building operator in the first instance, or contact us using the details in section 14, and we will direct your query appropriately.If you are unsure whether we act as a controller of your personal data, please contact us at any time using the details in the "Contacting us" section (section 14).

3. ABOUT OUR SERVICES AND THE DATA THEY USE

Our services work primarily with building and equipment data rather than personal data. To optimise a building, we collect telemetry from Internet of Things (IoT) sensors and controllers that we install, and from existing building systems (such as building management systems, HVAC units, electrical equipment, and energy meters). This includes measurements such as temperature, humidity, CO2 levels, energy consumption and equipment status, together with contextual data such as weather, tariffs, and grid signals.Some of this data may constitute or contain personal data in limited circumstances. For example, aggregate occupancy or presence signals used to adapt comfort settings, comfort feedback, and anonymous sex or gender estimations. We design our systems to use anonymised or aggregated data wherever possible, and we do not use image processing through cameras, audio recording or technologies that identify individual occupants as part of our standard service.

8. AUTOMATED DECISIONS AND PROFILING

8.1. Our technology makes automated decisions about buildings and equipment — for example, adjusting HVAC setpoints and schedules — not about individuals. These decisions are based on environmental, operational and contextual data as described in section 7.8.2. We do not make decisions based solely on automated processing that produce legal or similarly significant effects for individuals. If this ever changes, we will update this notice and ensure appropriate safeguards are in place, including the right to obtain human intervention, to express your point of view and to contest the decision.

9. DATA TRANSFERS

9.1. The personal data we collect may be transferred to and processed in a destination outside the UK and the European Economic Area ("EEA"), for example where we use cloud hosting or software providers that operate internationally, or where we engage with customers, partners or team members located abroad (including in Latin America).9.2. Where personal data is transferred outside the UK and EEA, we take steps to ensure it is adequately protected and processed in compliance with the Data Protection Legislation, such as:
- transferring personal data to a country or jurisdiction that has been deemed "adequate" by the UK government;
- entering into the UK Addendum to the EU Standard Contractual Clauses or the UK's International Data Transfer Agreement with the recipient; or
- relying on the recipient's certification under the UK–US Data Bridge extension to the EU–US Data Privacy Framework, where applicable.9.3. To find out more about how your personal data is protected when transferred outside the UK and EEA (or to obtain a copy of the applicable safeguards), please contact us using the details in section 14.

10. HOW DO WE PROTECT YOUR INFORMATION?

We take the protection of your personal data seriously. We implement a range of technical, physical and organisational measures to keep personal data confidential and secure, including:
- access controls so that personal data is restricted to those who need it for the purposes set out in this notice;
- internal data protection and information security policies governing the use, storage and processing of personal data;
- encryption in transit and at rest, firewalls and password protections, including for data transmitted from devices installed in buildings; and
- regular data protection and security training for our team.Where we have provided you with, or you have created, credentials to access any of our systems or dashboards, you are responsible for keeping them safe and confidential.

11. HOW LONG DO WE RETAIN YOUR INFORMATION FOR?

11.1. We only keep your personal data for as long as is necessary to fulfil the purposes set out in this notice and to comply with our legal, regulatory, accounting and contractual obligations.11.2. The retention period will depend on your relationship with us and the type of personal data. For example, records relating to a contract will generally be retained for the duration of the contract and for a period afterwards consistent with limitation periods; unsuccessful candidate records are retained for a shorter period following the conclusion of recruitment.11.3. If you have any questions about retention, please contact us using the details in section 14.

12. YOUR RIGHTS

12.1. It is important that any personal data we hold about you is accurate and up to date. Please keep us informed if your personal data changes.12.2. The Data Protection Legislation gives you a number of rights, which you can exercise at any time by contacting us using the details in section 14:
- the right to access your personal data: you are entitled to a copy of the personal data we hold about you and certain details of how we use it;
- the right to rectification: you can ask us to correct information that is out of date, incorrect or incomplete;
- the right to restrict processing: in certain circumstances, you can ask us to stop using your personal data, for example where you think it is inaccurate or no longer needed;
- the right to erasure: you can ask us to erase your personal data in certain circumstances, although this must be balanced against other factors, such as legal obligations that require us to retain it;
- the right to data portability: in certain circumstances, you can ask us to transfer personal data you have provided to us to a third party of your choice;
- the right to object to marketing: you can ask us to stop sending you marketing at any time;
- the right to object to processing: where we process your personal data based on our legitimate interests, you can object, and we will consider whether our interests are overridden by your rights;
- the right to withdraw consent: where we rely on your consent, you can withdraw it at any time;
- rights related to automated decision-making: you can ask us to review any solely automated decision that significantly affects you (see section 8);
- and the right to lodge a complaint with the Information Commissioner's Office (https://ico.org.uk/). Lodging a complaint does not affect any other legal rights or remedies you have.12.3. Not all of these rights are absolute, and there may be circumstances where we cannot comply with your request (for example, where it conflicts with our legal or regulatory obligations). If we cannot comply, we will tell you the reason, and we will always respond to any request you make.

13. ARTIFICIAL INTELLIGENCE

13.1. Artificial intelligence ("AI") refers to a range of technologies that use computer systems to perform tasks that would usually be carried out by humans. AI is central to our services: we use machine learning models to control and optimise buildings, as described in sections 7 and 8. We may also use AI tools to assist with capturing and summarising information during our communications and operations, for record-keeping, service delivery and complaint-handling purposes.13.2. We may use data to train and improve our AI systems. Wherever possible, we anonymise or aggregate data used for these purposes so that no individual can be identified.13.3. The following principles guide our use of AI:
a) Responsible use: AI is used in a way that is safe, fair and equitable.
b) Confidentiality: your confidentiality is protected at all times.
c) Compliance: we use AI in compliance with all applicable laws and regulations, including the Data Protection Legislation.
d) Training: we provide information, training and support to all staff who use AI to ensure they do so responsibly.
