Construction managers, investors, and job site contractors have a lot on their plate. Between organizing workers and keeping projects on track, job site security is a totally separate headache, but it’s still incredibly important. Managed video surveillance is one of the best ways to secure your job site against unwanted loss or damages, and yet, not a lot of people even know that live video monitoring services are a thing. Today, we’re going to define managed video surveillance and look at how it helps you protect your assets and mitigate risk on the job site. If you’re interested in how live video monitoring services stack up against other security assets, we talk more about that here. What is Managed Surveillance? Managed Surveillance is a more advanced version of live video monitoring. For standard surveillance systems, you rely on something like CCTV and recorded footage, or a small on premises security detail watching a limited number of feeds from around your construction site. With managed surveillance, you can expand the network of cameras, employ more advanced technology, and rely on a centralized team of trained security personnel keeping watch over your assets on a 24/7 basis. Usually, this is accomplished by hiring in a third-party security company that specifically offers managed video surveillance services. This helps you mitigate the cost of expensive surveillance tech, while also giving you access to a fully trained, contract based surveillance security team. Why Managed Surveillance Over Other Surveillance Setups? There are two main reasons to invest in managed surveillance: Compared to the equivalent level of security, training, and equipment in-house, it’s significantly more cost effective It’s one of the most effective security measures available in terms of broad coverage security You can essentially sidestep the expense associated with setting up your own security system and personnel with all the associated training, salaries, cost of equipment and so on. This makes managed surveillance one of the most cost effective forms of security available based on resource commitment alone. Managed surveillance is also particularly effective because it combines several elements from other security solutions in a more successful capacity. Think of managed surveillance as CCTV on steroids, with a whole trained security team watching the feed around the clock, ready to respond to threats, alert on site personnel, or contact authorities as soon as any kind of suspicious activity is detected. Utilize Managed Surveillance in Construction Site Security Now, let’s dig into what makes managed surveillance such a successful security solution. In most cases, it’s still best to use a variety of security measures to better defend your property against risk or accidental damages, but we’ll look at how surveillance works to enhance every aspect of security. Better cameras and surveillance equipment Compared to CCTV or localized live feeds, most managed surveillance services incorporate newer technologies that do more than simply provide and record a video feed. In some cases, a surveillance team might employ thermal imaging technology to counteract bad lighting or inclement weather, and many services are moving towards solar-hybrid camera power backups to provide consistent uptime. In both cases, this helps site managers be more aware of what’s going on at their job site, even when nobody is there in the middle of the night. The increased surveillance capacity also helps mitigate on the job risks, catching accidents and preventing additional damage by immediately alerting someone when accidents do happen. More strategic application of surveillance tools One of the major benefits for managed surveillance service is the training and security expertise of the team providing the service. In order to provide the best surveillance, a security team needs to develop a solid understanding of your job site. That means highlighting vulnerable or high value areas, recommending additional security measures as needed, and setting up the surveillance system to maximize coverage. This process of strategic security planning can make surveillance even more effective, by predicting where incidents are more likely to occur, and setting up cameras and potentially supplementary security measures to prevent or discourage those incidents. Always on, always staffed monitoring component Finally, the real major difference that sets monitored surveillance apart is the fact that it’s an always-on, 24/7 process staffed by professional and experienced security personnel. For example, there may be a centralized hub where personnel are constantly monitoring live feeds for your property. This security team is trained to recognize and respond to threats appropriately, and some services may even offer forensic video evidence collection and review to further protect your assets. As a single package, this always-on human element combined with improved camera and surveillance tech is what makes managed video surveillance such an effective security measure. Of course mixing in additional measures, like on-site guards or physical barriers can only improve the safety of your property. Why is Managed Surveillance Perfect for Construction Job Site Security While managed surveillance is a great asset for any kind of property or security application, it’s particularly well suited for construction sites and industrial areas because it affords a high level of coverage alongside flexible use cases. Construction sites suffer from a number of specific issues that can make security a difficult task: Limited access to power supplies Huge square footage that needs to be secured A variety of high value areas that need protection Complicated schedules and interaction by workers Limited Access to Power Many construction sites aren’t fully outfitted with access to a power supply, which can make other forms of security difficult. For example, alarms, lighting, and CCTV all need a reliable power source, otherwise they’re essentially just plastic stapled to the wall. Managed surveillance, and more specifically, the investment in solar powered cameras and tech means that you don’t have to worry about power issues. Your property will be safe and secure, even if the power goes down. Huge Square Footage A lot of construction sites are big. That means you’re stretched thin relying on security guards, physical barriers, or motion triggered alarms. With surveillance cameras, it’s much
The Building Engineering Services Association (BESA) has put its weight behind a call from six trade unions to take urgent action over ventilation in schools. In a letter to the Education Secretary, the unions have warned that there will be a steep rise in Covid-19 cases when children return to school next month without improvements to airflows and filtration in classrooms and communal areas. They say there should be government funding for carbon dioxide monitors to measure the effectiveness of ventilation, and filtration to remove harmful airborne particles. “The benefits of ventilation in the control of airborne diseases are already well understood and accepted,” their letter said. The National Education Union (NEU), NASUWT, the Association of School and College Leaders (ASCL), the National Association of Head Teachers (NAHT), GMB, Unison and Unite have joined forces to push for a more strategic approach to school ventilation. “Government action on ventilation in schools and colleges amounts to little more than recommending that windows are kept open,” said ASCL general secretary Geoff Barton. “This is not sustainable in providing a comfortable learning environment in the depths of a British winter. “If the government is serious about bringing to an end the educational disruption of the past 18 months, then it must provide funding for high-quality ventilation systems as a matter of urgency.” The unions also pointed out that many school windows were painted shut and could not be opened. Threats BESA has produced two pieces of guidance this year to help building managers set up indoor air quality (IAQ) strategies and identify the main threats to health and well-being from airborne pollutants. Using mechanical ventilation systems and targeted filtration is recognised as the most effective way to reduce the risk of disease transmission, but no specific government funding has been allocated to help schools address this issue. The CEO of a primary school trust told a recent BESA webinar that lack of funding prevented schools from addressing the problem. Garry Ratcliffe said that despite greater awareness of the risk of transmitting airborne infections during the pandemic, mechanical ventilation remained a low priority for most headteachers. Ratcliffe, who is CEO of Kent-based Galaxy Trust, said current Department for Education (DfE) guidance was inadequate. “Would it be acceptable advice to tell people in a workplace to open their windows and wear warmer clothes?” he asked. He also said he was concerned that opening windows could be “doing more harm than good” because many schools were close to busy roads, so the children were being exposed to high levels of traffic pollution and noise. He said his three schools had already spent over £325,000 on Covid mitigation measures but had only been able to reclaim £57,000 from the government. Each has an annual capital budget of just £7,000, which is primarily to ensure buildings remain safe and to fix leaking roofs and heating. “If we wanted to free up money to spend on a new ventilation system, we would have to make cuts elsewhere. However, we are judged on the quality of the education we provide…not on the quality of the air.” The BESA guides highlight the fact that opening windows does not provide controlled ventilation. It is not an effective method of managing the direction of airflows to provide the air change rates needed to dilute airborne contaminants and viruses in every part of a room. NEU joint general secretary Kevin Courtney said: “It is shocking that, rather than taking concrete steps now to improve the situation, the Department for Education has only just announced a pilot scheme, involving 30 schools in Bradford, to trial the use of air purifiers, with results not due until the end of the year. “18 months into the pandemic, and given the accumulated knowledge about ventilation, kicking the issue into the long grass in this way is simply not good enough.” BESA’s guidance calls for a mixed approach to ventilation using both mechanical and ‘natural’ systems that can minimise costs for schools, but greatly improve airflows and give teaching staff more control over their indoor environments. “The ventilation industry has a wide range of solutions – many of which can be tailored to schools,” said the Association’s head of technical Graeme Fox. “They are relatively low cost, but they are not free. The government does need to put some level of investment into this and not just to deal with the immediate Covid issue, but to improve indoor conditions for the long-term health and well-being of pupils and staff.” He said BESA members had been flagging up the problems caused by air pollution inside school buildings for many years. “There is a powerful body of evidence linking poor IAQ to rising numbers of children suffering from asthma and other respiratory conditions that have serious long-term implications. BESA applauds the stance taken by the education unions and our industry is standing ready with the solutions they demand,” added Fox.www.theBESA.com/iaq
Gas safety campaigners are warning that a boom in home moving and improving, combined with a pandemic-squeeze on people’s finances and a lack of understanding about insurance policies, risks jeopardising health and wealth in 2021. With many entering 2021 suffering from the negative economic impacts of the Covid-19, pandemic, cutting costs this Winter is a priority. New research from the Gas Safe Register – the UK’s official registration body for gas engineers and gas businesses – shows that just under half of householders (49%) say the pandemic has made them thriftier, prompting 45% to try ‘doing it themselves’ rather than relying on qualified, legally registered professionals for improvements and renovations. However, these efforts to save could actually prove more costly – almost 90% of the 2,000 householders surveyed did not realise home renovations can impact their home insurance cover and large numbers can’t identify some of the most common things that could invalidate policies, leading to future claims being rejected. These include: Using faulty home appliances (61% were unaware) DIY damage caused by improvements such as such as re-locating a gas boiler, building a conservatory, or similar (50%) Not using a certified tradesperson for carrying out gas and electrical work or repairs in your home (48%) Accidentally invalidating your home insurance policy can be distressing, both emotionally and financially – but over half (51%) of Brits admit to never having read their home insurance policy in full. However, for safety reasons, gas, electrical and plumbing works must be carried out by a registered professional. Tackling these types of job unqualified can invalidate home insurance and warranties, leaving people significantly out of pocket if something goes wrong. In fact, according to data from the Association of British Insurers (ABI), 82.2 per cent of claims are accepted, while the average cash amount people claim for on their home insurance is £2,627*. The pandemic has sparked a sharp rise in people in wanting to relocate and change their housing situations, with a near two-fold increase in volume of agreed UK sales by last autumn alone*. This booming property market is set to see last year’s trend for renovations and DIY continue, as over a quarter (26%) of Brits plan to carry out major improvements in their homes over this coming year. To help these millions of movers and improvers stay safe and save money, Gas Safe Register has teamed up with TV personality and DIY expert, Jo Behari as part of its Safety Starts at Home public awareness campaign. Behari says: “When moving home or deciding to make big home improvements, it’s easy to get caught up in the aesthetics or keeping costs down and let home safety take a back seat. Before deciding to embark on any work, I urge all homeowners to ensure that the tradespeople they hire are properly qualified to safely and legally carry out the work. “Worryingly, two thirds of gas work carried out illegally – by people not registered with the Gas Safe Register – is found to be unsafe. At worst, the consequences can be devastating, but it can also invalidate your home insurance. People need to check their home insurance policies so they’re clear on how work might impact their ability to make a claim. Always make sure you use a Gas Safe Registered engineer for gas work, checking they’re certified and on the register. Like with our health, prevention is better than cure when it comes to gas safety and keeping you covered for the unexpected. Having your gas appliances checked annually by a registered engineer means you won’t risk invalidating your insurance by continuing to use appliances that have developed faults.” Jonathan Samuel, chief executive at Gas Safe Register says: “We’ve spent so much more time in our homes recently it’s natural people have looked to move and improve. We’re stressing the importance of not cutting corners when gas is involved, even when finances are squeezed. “While DIY-ing directly with gas appliances is the most obvious way to cause a gas emergency, there are other projects that can indirectly put you at risk. For example, accidentally drilling a hole through a gas pipe while attempting to put up shelving. “Whether it’s gas emergency, planned maintenance or improvements, it’s vital you seek the help of a registered expert. Gas engineers are listed as key workers and as such, are still conducting home visits, with the necessary precautions in place, during this period of social distancing and staying at home.” Kate Devine, insurance expert at MoneySuperMarket said: “Attempting home improvements yourself which involve significant building work, or even gas and electrical work, rather than using a legally registered professional can seem like a great way to save money. However, doing so, can easily leave you exposed to having a claim refused and significantly out of pocket, should you need to call upon your home insurance policy and you have unwittingly invalidated it. “My advice is to always be clear on what your policy covers you for and what it doesn’t. Read the Ts&Cs and make sure you enter your own details correctly.” Download the Gas Safe Register’s free winter guide for useful information on how to stay gas safe during the colder months of the year.
A report commissioned by the government’s chief scientific adviser Sir Patrick Vallance has highlighted the crucial role played by building ventilation in reducing the risk of Covid-19 and other infections, but it misses some crucial practicalities, according to the Building Engineering Services Association (BESA). The report, which was produced by the National Engineering Policy Centre (NEPC) – a group of 43 professional engineering organisations led by the Royal Academy of Engineering – revealed flaws in the design, management, and operation of buildings. It advised Sir Patrick that, unless these flaws were addressed, they could disrupt the management of this and future pandemics, impose high financial and health costs on society, and constrain the UK’s ability to address other challenges including climate change. However, BESA said the problem was that many buildings were designed in a way that made it very difficult and sometimes cost prohibitive to fit the systems needed to achieve adequate ventilation. It said the government should link its ambitions for climate change mitigation and sustainability to work on ventilation and overheating in buildings and consult with all parts of the engineering and construction sectors to get a joined-up solution. “It is very positive that the government’s top scientist recognises the importance of raising standards of building ventilation to deal with this and future pandemics, but he is only getting part of the picture,” said the Association’s head of technical Graeme Fox. Solutions “The knowledge of professional institutions is hugely valuable, but unless they align their theoretical expertise and design philosophies with industry practitioners who operate at the sharp end and know what it is achievable, we will not be able to deliver the solutions the country needs,” he added. BESA said building designers needed to consider practical measures like allowing enough space in ceiling voids to add or improve mechanical ventilation systems. Enabling access for maintenance purposes, cleaning ventilation ductwork and fitting or renewing air filters were other crucial factors often overlooked during design and fit-out phases. The Association also highlighted the recent report from the Climate Change Committee (CCC), which warned that many new buildings were being developed without adequate adaption measures, which means they would be prone to overheating as our climate warms up. The CCC identified overheating in buildings as a major climate change risk and health emergency in 2016, but since then 570,000 new homes had been built without climate adaption measures and a further 1.5 million were due to be built in the next five years. Fox said there were more than 2,500 heat-related deaths during the 2020 heatwave in England, which was higher than at any time since records began, and that the CCC expected heat related deaths to treble by 2050. “The government needs to understand the concept of a sustainable built environment in the widest sense,” he said. “Sustainability is not just about carbon and energy saving, it is also about ensuring that the facilities we build and refurbish are able to sustain human activity in the long-term while also safeguarding health, well-being, and productivity. “It is highly possible that a huge proportion of the homes and commercial buildings being designed now will no longer be inhabitable in a few years’ time because they are too difficult to cool and ventilate.” BESA has recently released new technical guidance to help contractors deliver indoor air quality (IAQ) solutions to transform existing buildings into ‘safe havens’ for people including how to minimise the risk of transmitting diseases via airborne particulates. “The vast majority of the work needed to create safe and healthy indoor spaces will be retrofit and so we need a strong focus on low cost, practical measures that can actually make a difference to people’s lives,” said Fox. “Professional institutions should not be expected to provide that kind of work on their own. This requires a joined-up approach from the whole construction and building engineering supply chain.” Consistency The RAE report: ‘Infection Resilient Environments: Buildings that keep us healthy and safe’ called for the plugging of skills and knowledge gaps and criticised the lack of building management consistency in healthcare settings. It added that investment in research and development was needed to clarify acceptable minimum standards for ventilation to support regulation by Local Authorities and others. “We welcome the report and agree with many of its findings, but it only goes so far,” said Fox. “We have a big job to do in defining what we mean by the skills required to tackle the major health threat to people posed by buildings that have been designed to trap heat in order to minimise energy use. “If you design tight you have to ventilate right and, unfortunately, our members come across buildings that have locked in air quality and overheating problems on a daily basis. This also needs to be explained to government at the highest level so that investment can be targeted in the right areas.” www.theBESA.com/iaq
When news that confirmed COVID-19 being airborne broke out, everyone understandably got more cautious. By that time, it’d been almost a year since initial evidence suggested that the virus could spread within one meter of an infected person. More people have either fallen ill or succumbed to the disease over that timeframe. As the United States and most parts of the world slowly regain some normalcy, various industries aren’t leaving anything to chance. Offices and stores will be reopening, and adequate ventilation—reorienting vents, installing high-efficiency filtration systems—and adopting new workplace safety protocols can’t be stressed enough. In other words, the new status quo demands rethinking the way air flows within a building. While such changes are no substitute for health protocols (i.e., physical distancing, wearing face masks, etc.), an efficient ventilation system can contribute to a safer workplace. With that said, in this post, you’ll get to know some ways offices and stores can safeguard the well-being of their customers and employees. Displacement ventilation Proper building ventilation warrants deriving more air from outdoors. While the downside is an increase in energy consumption, this system will expel airborne pathogens and other particulates more often. You might have to shell out few extra dollars in utility costs, but that’s a small price to pay for keeping everyone safe. (1) If a higher energy bill is out of the question, consider refitting the facility with a displacement ventilation (DV) system. First implemented in Northern Europe, DV relies on fluid dynamics—namely, how cold and warm air move. (2) Cold air enters the room through vents placed close to the floor, where it gets heated and rises to the ceiling. The warm air then exits the building through vents in the ceiling. Unlike traditional ventilation systems, DV only requires less velocity in taking outdoor air in, meaning the fans can run more slowly and for a more extended period. (2) However, DV works best under the following conditions: Contaminants are light enough to move with the rising warm air Incoming outdoor air is much cooler than the air inside the room Minimal disturbance to the room’s airflow The minimum advisable ceiling height is nine feet Noise should be as low as possible (2) Layered approach Since COVID-19 made landfall in the United States, the Centers for Disease Control and Prevention (CDC) have introduced guidelines in minimizing its spread. While most of these are related to personal hygiene, there are also guidelines on proper ventilation. The CDC COVID ventilation requirements include taking a layered approach to reduce the risk of spreading the virus. Aside from increasing outdoor air intake, the requirements justify adding new exhaust fans, repositioning existing exhaust fans closer to windows, and installing air filters in high-risk areas. Improving ventilation is just one layer in this multifaceted method. The office management also plays a role, keeping a skeletal force as much as possible, rearranging office cubicles and rooms, and regularly disinfecting surfaces. The more safety protocols offices and stores introduce, the lower the risk of COVID-19. (3) Filtration and ionization Just as in overall COVID-19 risk reduction, the ventilation system should also have multiple layers. Every part, from intaking and removing air, must be active in ensuring everyone in the office or store breathes safe air. At the heart of this system is the air filter. Commercial spaces should employ high-efficiency particulate air (HEPA) filtration systems designed to capture particles as small as 0.01 microns. The COVID-19 virus is estimated to be around 0.125 microns (contrary to popular belief that it’s 0.3 microns small)—well within a HEPA filter’s capture range. (4) Augmenting the filtration system with standalone air cleaners can add an extra protective layer. However, be aware that some portable air cleaners in the market generate ozone, which can be harmful at high levels. The jury is still out on the effectiveness of bipolar ionization against harmful pathogens and particulates, but it’s better not to rely on them too much. (5) Regular maintenance No amount of advanced ventilation technology will reduce a commercial space’s risk of COVID-19 if it doesn’t work as intended. Ventilation systems should undergo systematic maintenance every three to five years to clear out the buildup of particulates in the ducts. Even as ducts, filters, and fans grow more reliable, maintenance shouldn’t still be taken lightly. Conclusion It’s unlikely COVID-19 will go away anytime soon, especially with its more contagious variants still running rampant. While waiting for more people to be immunized from the disease, preparing safe spaces for customers and employees should be a priority for reopening offices and stores. Updating or overhauling ventilation systems will go a long way in doing so.

The removal of most Covid restrictions in the UK has increased calls for clearer practical guidance and the setting of specific indoor air quality (IAQ) contaminant targets to support the health and wellbeing of building occupants. The Building Engineering Services Association (BESA) has, therefore, produced a concise guide to good practice: ‘Indoor Air Quality for Health & Well-Being’, which is designed to help building owners, managers and engineers interpret IAQ data and turn it into useful strategies for improving the indoor environment. The UK’s chief scientific officer Sir Patrick Vallance and the British Medical Association (BMA) have emphasised the role of building ventilation and IAQ in helping the country navigate the next stage of the pandemic. The BSI is also fast-tracking a new British Standard that will help to define the UK’s future approach to IAQ. The BMA, which represents all UK doctors, says setting legal standards for ventilation, should be part of the government’s strategy for dealing with the next stage of the pandemic. It added that financial support for businesses and educational settings should be made available “to implement these requirements ahead of the autumn and winter period, when respiratory viruses spread more easily and buildings must be kept warm, limiting options for natural ventilation”. The new BESA guidance, which is part of the Association’s wider Buildings as Safe Havens (BASH) campaign, sets out target limits for a range of airborne contaminants in a variety of indoor spaces. It explains how air quality data gathered during specialist surveys or from the wide range of low cost real-time and continuous IAQ monitoring devices, can be interpreted and acted upon. Achievable The advice it provides is also based on the experience of practitioners in the field who see what is possible and achievable in the real world. It is designed as a follow-up to the BESA publication H&W001: A Beginners Guide to Indoor Air Quality published in March in collaboration with Mitsubishi Electric. Public Health England estimates the annual death toll in the UK from air pollution at between 24,000 and 36,000 with associated healthcare costs as high as £20bn. The role played by indoor air both in transmission of disease and the general health and wellbeing of building occupants became headline news during the pandemic and has prompted unprecedented interest in how buildings are ventilated. The BESA Guide has also been produced in the wake of a report commissioned by the government’s chief scientific adviser Sir Patrick Vallance, which highlighted the importance of building ventilation in reducing the risk of Covid-19 and other infections. The report was published by the National Engineering Policy Centre (NEPC), which is a group of 43 professional engineering organisations representing 450,000 engineers. It found that ventilation was often neglected, and that the Covid-19 crisis had revealed flaws in the design, management, and operation of buildings. It advised Sir Patrick that, unless these flaws were addressed, they could disrupt the management of this and future pandemics and impose high financial and health costs on society. Nathan Wood, chair of the BESA Health & Wellbeing in Buildings group, said this was a significant moment for anyone working to improve the indoor environment. “The very fact that such a senior adviser is taking a close interest in how the engineering profession can be deployed to tackle a health and wellbeing issue shows just how high this has risen up the political agenda,” he said. “People now need reassurance that buildings are being adequately ventilated, and the air monitored to minimise the threat from contaminants and viruses. This new BESA Guide aims to do just that, but it also goes further. “Rather than purely focusing on preventing infection and death, which is often the approach of academic and regulatory work, it also promotes a positive approach to setting IAQ standards that will give people a healthier, more comfortable, and more productive experience inside buildings.” He pointed to research carried out by Harvard University in the US that showed a 61% improvement in cognitive function for students in a well-ventilated, clean environment. “The outdoor, ambient air pollution guidance levels adopted by governments are usually based on mortality and morbidity, tempered by what is regarded as economically feasible. That compromise reduces investment in the health and wellbeing benefits,” added Wood. Enjoyment “By contrast, a health and wellbeing approach considers how good IAQ can improve productivity and enjoyment of a space and supports the principle that people should be able to inhabit ‘safe havens’ where the indoor air is better than the polluted outdoors. Unfortunately, in too many cases, the opposite is currently true.” The BESA Guide refers to established guidelines including those provided by the World Health Organisation (WHO), which are due to be updated later this year. It also signposts other sources of authoritative advice on volatile organic compounds, formaldehyde, nitrogen dioxide/oxides, ozone, radon, and airborne micro-organisms. It also recommends monitoring CO2 and a range of IAQ factors to balance good air quality with reduction of internally and externally sourced contaminants. Its guidance will also be offered to the BSI to help shape the draft BS40101 ‘Building performance evaluation of occupied and operational buildings’, which is due to be published in November and is currently the subject of a public consultation. “I would like to thank the amazing people who contributed so much of their time and expertise to the preparation of this guidance, particularly Douglas Booker, Craig Booth, Peter Dyment, and Shaun Hill; supported by the wider membership and staff of BESA,” said Wood.

It is common that one of the main concerns to take into account when travelling is the hotel where you are going to stay, especially if you are going to stay for a long period of time. Clients tend to look for a hotel in accordance with their economic possibilities and always taking into account their needs. It is true that the design of the hotel, the construction of the building, the reception area and the lounge/dining room for meals are one of the main attractions before deciding to stay in a specific hotel. But what really pleases a client the most and what he/she will notice the most is the room where he/she is going to stay and feel comfortable after a whole day working or sightseeing. That is why every detail counts, from a comfortable bed to a warm and pleasant light. So, what about the security in a room? Can we guarantee the safety of our most precious valuables or the money we want to keep in the room? In this sense, it is important to have an electronic lock with an attractive design and which, of course, fulfils its main function: guaranteeing security through state-of-the-art opening systems such as Bluetooth, numerical code or proximity cards. A good combination of design and functionality will make the customer feel in his comfort zone and give the hotel in question a good appearance and care for its guests. In the following, you will find two types of electronic locks chosen for their design and minimalism and which can be found for sale at Omnitec Systems, a company with more than 25 years of experience in the development, manufacturing and marketing of locks, minibars, access controls and safes. Therefore, it is a company that manufactures and offers solutions for hotels, always focusing on the most appropriate and minimalist design possible that enhances the guest experience and the feeling of luxury. The EVO electronic lock This first type of electronic lock, noted for its minimalism and subtlety, is often one of the best and most common choices for hotels looking for high technological features combined with a minimalist, attractive and user-friendly design. What is most striking about this electronic lock is its mechanism, as it is fully integrated into the door. The only thing that is visible is the doorknob, the keyhole and the reader that works via Bluetooth and Smartphone or with a MiFare proximity card. Depending on the preferred configuration, no electronic mechanisms will be visible, thus fully respecting the decorative concept of the hotel and the interior of the room. It is a very discreet, elegant electronic lock that fits both classic and more modern styles. In addition, this type of lock guarantees maximum security for guests and their belongings, as the system used to open and close the door can always be synchronised with the hotel’s reception computers, and you can alway opt for remote opening and management. OS-SLIM Secondly, there is the OS-SLIM option, an electronic lock with a high technological level in a sleek profile design. As mentioned in the previous case, this lock is also a very elegant option and stands out for its modern anddetailed technological configuration system. This model offers a clean, modern and innovative feel to the door and the surrounding space, both to the guests in the room and to anyone passing by.

In short, this type of electronic security system is becoming more and more common in the hotel sector, which is why it is recommended that you contact the Omnitec team if you have any doubts about this type of electronic lock, as they will be fully prepared to help you and provide your hotel’s security system with modernity and comfort.
Two tech companies have joined forces to create a new turnstile with an in-built software system to improve safety and security on construction sites across the UK and Ireland. Security technology company Envision Intelligent Solutions, which also has offices in Northern Ireland, England and the USA, teamed up with software development firm NTD (North Time and Data) to launch the latest development of their bespoke security turnstile that uses facial recognition technology and records temperatures to help ensure a Covid-free workspace. The Gateway Turnstile, which is manufactured by Envision, incorporates a new cloud-based software system that links directly to the company’s payroll and HR systems. The first turnstile with the new cloud-based software has rolled off the production line and has been shipped to a large building site in Chepstow in Wales for construction fit-out company Beacons Business Interiors (Bbi Group). Philip Murdock, Envision IS Managing Director said: “Our clients in the construction industry asked for a bespoke security system that incorporated facial and thermal access readers with a time and attendance system, which is completely cloud networked. During the pandemic, they needed a contactless product that could link back to their head office and provide the data in real time.” Amanda Campbell Envision IS Commercial Director added: “Envision moved quickly to get contactless turnstiles to the marketplace to support construction companies to keep sites open and personnel safe.” Envision partnered with NTD to create the cloud software for the new turnstiles that gave construction companies improved security and communications between the sites and their head offices. NTD adapted its successful NT Pro Workforce Management System to the requirements of the construction industry. NTD Managing Director Stephen Brown explained: “The Biometric Facial Recognition Terminals and NT Pro Software not only record the time and date of an employee coming onto a construction site, but it also takes their temperature and alerts management if an employee has a high temperature. We believe that with this partnership, there will be a well-structured and user-friendly system that makes it easy for smooth operations and overall profit maximization.” The software comes with modules that are particularly useful to construction site security. For example, it allows companies to upload CSR/CSCS qualifications and gives access to personnel training files that can all be viewed from the live dashboard ensuring health and safety qualifications are up to date. Additionally, the software provides full job costing, financial reporting and statistics. The first turnstile was shipped to commercial fit-out specialists Bbi Group, which design, fit-out and refurbish commercial premises across the UK. The company has secured a contract to completely refurbish a 20,000m2 storage warehouse in Chepstow and will have approximately 100 people working on site over the 13-month period. Dave Bastier from Bbi said the company chose the Envision Gateway turnstile as it needed an efficient means to control access to and from site that would not cause an issue with social distancing and contamination of touch surfaces. He said: “The Envision Gateway has been positioned between the car park and the principal entrance to site and provided the perfect solution to that need. Training and backup for our site administrator has also been excellent.” For more information on the Gateway Turnstile go to www.envision-is.co.uk
The popularity of indirect free cooling of data centres in the Nordics region could place facilities at risk of corrosion if conditions are not correctly controlled this summer, according to temporary solutions specialists Aggreko. According to a recent market report by Arizton, the Nordic region can facilitate up to 8,400 hours of data centre free cooling annually due to its colder climate. Though incoming ambient air is filtered before entering the controlled data centre environment, this process can result in temperature rises of two to four degrees. When combined with rising summer temperatures, data centre sites may experience higher moisture levels that could lead to condensation forming and rising water temperatures. Keeping key data centre components like electrical distribution systems dry and within a certain temperature band phase is crucial to ensuring its continued running. According to Aggreko, not taking steps to account for changing temperatures during the construction phase could lead to long-term damage that could impair functionality and void warranties. “The ability to use the climate as a resource to help free-cool facilities is one of many reasons the Nordics region appeals to organisations looking to construct data centres,” says Greger Ruud, Sector Development Manager – Nordic Datacenters at Aggreko. “However, it must be noted that like any other region, there are fluctuations in temperature depending on geography and the seasons, so conditions will occur that make free cooling more challenging. “Site managers must therefore be aware that a rise in ambient air temperature will be reflected in the data centre environment, especially with filtration processes generating added heat. As such, plans should be put in place to cool facilities and maintain controlled conditions during the upcoming warmer months.” Additional cooling solutions like chillers and dry coolers may be used to ensure controlled temperatures during warmer periods. But with this further cooling capacity only required for a short but critical time period, expensive new equipment bought for this purpose will likely be redundant for long stretches. An innovative strategic hire approach may therefore represent the best way of alleviating both financial and humidity risks. “Optimum conditions for free cooling occur in the Nordics for the majority of the time, but crucially, not all of the time,” Greger concludes. “These temporary conditions require a temporary response, so hiring data centre cooling equipment like chillers and dry chillers may appeal. “Taking this approach can help site managers to alleviate damage risks without being shackled to expensive, permanent equipment that will not require year-round use. With COVID continuing to constrain budgets in all sectors, this freedom can allow contractors to be more dynamic as pandemic-enforced social restrictions are loosened and demand rises further.” For more information on chiller and dry cooler solutions for your data centre site, visit www.aggreko.com/datacentre.
A leading independent lighting manufacturer says retrofitting outdated lighting systems will be key to improving energy use across the public sector, as more local authorities commit to beefing up their net zero plans. UK100, a network for UK locally elected leaders, recently announced that nearly 60 local authorities, representing 35% of the UK population, had committed to meeting net zero at least five years earlier than central government1. Tamlite’s Head of Market Intelligence Colin Lawson says that whilst innovative technologies are quite rightly at the forefront of plans to achieve these ambitious targets, with 404 local authorities in the UK, more can be done, and there are simple and cost-effective measures that can be introduced by public sector organisations. Indeed, he believes many have forgotten the impact lighting can have on reducing carbon emissions and cutting energy bills. By replacing outdated lighting systems, coupled with intelligent control systems, it will help the public sector make their buildings more efficient. He comments: “Local authority leaders are showing real commitment to achieving net zero targets ahead of 2050. And whilst many are looking towards new technologies as the core of their decarbonisation plans, we cannot forget the simple steps that can be taken to make sure carbon reduction targets are met. “Lighting is a huge source of energy consumption in the public sector, and small changes can make a big difference. Replacing outdated lighting with modern LED systems can effectively reduce energy use and carbon emissions. Such retrofitting upgrades are easy to do and should be seen as the key component of the Government’s green strategy allowing public sector organisations to make a long-term commitment to net zero carbon emissions.”
