Rugby High School enjoys ‘significantly improved’ illumination from energy saving LED upgrade

The comprehensive LED-based lighting upgrade is expected to deliver annual savings of £12.5K and a return on investment of only 4.5 years.

Increasing instances of lamp failure, a recognition that the quality of the illumination could be better, and a desire to take advantage of energy savings accruing from the latest LED technology informed a recent upgrade at Rugby High School in Warwickshire. The major, site-wide overhaul was undertaken by Energys Group and funded by Utility Rentals’ operational lease scheme.

As the school’s Business Manager, Allan Kerr, explains, “it had been clear for a while that the old lighting was nearing the end of its useful life. Lamps were beginning to fail on a more regular basis, meaning that we were spending more money on replacements and maintenance. In addition, we were working on plans for a new sports hall, and if we had kept with the existing lighting we would have had to increase our electricity supply.”

Having engaged the services of energy efficiency technology specialist Energys Group to advise on the project, it quickly became clear that a comprehensive LED lighting upgrade would both reduce demand on supply and enable substantial energy savings. Consequently, the two parties began work on a lighting overhaul to encompass the main hall, music theatre, classrooms, science labs, gym, sports hall, corridors, staircases, communal areas and the languages block.

‘Dramatic improvement’

The resulting installation draws on LED products from across the Energys Group range, and includes tubes, panels, down-lighters, spotlights, wall-lights, outdoor fittings and flood-lights. Mere weeks after the project was completed – with a minimum of disruption to the operational practices of the school – it was evident to school management and personnel quite how much of an improvement the new systems had delivered.

“For the first few weeks after the deployment staff kept coming up to me to remark upon the new lighting. In particular, the increased standard of illumination in the main hall, gym and science labs was singled out for specific praise,” recalls Kerr.

Whilst the quality of the lighting was immediately apparent, its benefits in terms of energy savings will become more evident over the medium to long-term. As a result of the massive upgrade – which ran to 712 new LED lamps and 575 LED fittings – Energys predicts a return on investment of just 4.5 years. Annual energy savings are expected to total £12.5K and approximately 104,985 kWh’s, with a reduction in CO2 emissions of 55.84 tonnes per year.

Raj Gunasekaran, Business Development Manager at Energys Group, says that “the improvement in lighting conditions across the entire site is very discernible, and of course the energy savings are also going to be very welcome – particularly in the current challenging economic climate for the education sector. But it’s also important to highlight that improved lighting often translates to happier pupils and staff, meaning increased productivity and quality of work.”

‘Brilliant scheme’

However, there is another important element in the mix here and that is the funding provided by Utility Rentals. Having investigated some other schemes but concluded that they were unlikely to deliver the finance in the necessary time-frame, Kerr instead applied to the Utility Rentals operational lease initiative, with Energys Group providing guidance and assistance throughout the process.

As Utility Rentals director Steve Mattey explains, the scheme is fast, guaranteed and “available for any school in the country – no matter what size or establishment type. The rental scheme is cash-positive from day one, with repayments covered by the energy costs saved. The repayments are also fixed and won’t go up year on year, and can even be deferred until 12 months after the lighting has been installed.”

The Rugby High School application was successful, and Kerr reports that he was struck by “how straightforward the process proved to be. I am also pleased with the fact that if any failures occur, replacements will be provided at no cost. It really does take the risk element out of what has been a substantial undertaking.”

Reflecting on the completion of another comprehensive lighting upgrade in the education sector, Gunasekaran says that “the benefits Rugby High School is now experiencing as a result of implementing the latest LED lighting technology are now increasingly commonplace throughout this market. At Energys we are able to support this transition with a comprehensive range of LED solutions, so it’s no surprise that we have many comparable projects on the agenda for the rest of 2017.”

Energy bureaus can reduce energy consumption of HVAC systems

Brin Sheridan, Chief Operating Officer at Utilitywise PLC, one of the UK’s largest and leading independent utility cost management companies; comments on how modern day intelligent energy bureaus can reduce energy consumption of HVAC systems.

Historically standard bureaus would review utilities metering data to assess and identify inefficiencies in building and equipment performance and consumption. This data analysis allows the bureau team to deliver insights, allowing businesses to make changes to the way in which they operate or manage their buildings/equipment with the aim of reducing utilities costs and consumption.

This facility identifies and manages inefficiencies such as out of hour’s consumption, high base loads or peaks in consumption. UK businesses are becoming more aware of the ability to map and interpret utilities metering data against building and equipment performance to identify inefficiencies in consumption and wasted costs.

Today’s intelligent energy bureau provides all this and much more. Inefficiencies in equipment and building performance can be identified and delivered as actionable insights to the maintenance teams. The Intelligent bureau, like the one from Utilitywise, brings utilities market intelligence as well as experience around procurement contracts. This additional service enables businesses to reap further savings not only from the improved performance of their buildings but also from their utility bills.

At Utilitywise, we embrace the opportunities for our clients in delivering this intelligent bureau.  We believe bureaus that bring together maintenance efficiencies, consumption monitoring, market intelligence and procurement contract expertise deliver more savings and benefits for business owners.

Our market intelligence teams, data scientists and building optimisation engineer’s work together as part of this intelligent bureau to provide customers with the best solution.

This collaborative approach helps reduce utility costs, while ensuring building and equipment efficiency. The aim of this way of working is to deliver actionable insights to educate and quantify the business benefits through a number of media, from apps and cloud based software platforms. This is particularly advantageous with Smartdash, our analytical Report Builder platform and central engineering portal.

Intelligent energy bureaus:

  • We bring in our extended knowledge of the energy markets and trends as well as procurement contracts to work with our customers to reap greater savings from their utilities bills.
  • We look at utilities data to improve building and equipment performance, feed maintenance teams information to aid in proactive preventative maintenance programmes and provide the case for BeMS/controls.
  • We can identify inefficiencies in consumption, quantify their effect on the utilities bill and validate the improvements achieved through controls and changes in equipment operations.
  • We also consider the make up of the procurement contracts to allow our customers to benefit from time of day tariffs. This is done by shifting and shedding load when utilities consumption per kWh is greatest (known as DUoS and TRiAD avoidance).
  • We can seek out maintenance issues and also respond to any fault alerts, twenty-four hours a day and analyse reasons for the fault and either fix the issue remotely or arrange for an engineer to resolve the issue.
  • We help provide reports and visibility that businesses need for internal presentation and evaluation.
  • We offer an all-encompassing solution that provides services both sides of the meter, from procurement contracts to find the best deal for our customers through to analytics and controls to effectively and proactively reduce consumption costs.

The intelligent bureau should offer building owners and occupiers the ability to reduce inefficiencies in performance, manage out of hours’ consumption but also shift or shed consumption when prices at that time of the day are greatest.  Forward thinking and intelligent energy bureaus like ours, can also control consumption and cost while looking forward to market changes. With our ability to undertake long term forecasting, we can also predict future utilities bills for our customers and when we factor in their controls around time of day tariffs and against TRiAD alerts and the forthcoming changes to capacity markets there is more opportunity for business owners in their efforts to reduce costs. Last year, we saved our customers over 25% off their TRiAD bills thanks to our alerts and automation into our controls devices.

There are a number of drivers for these forward thinking, intelligent modern day bureaus but the most recent and current would be the forthcoming P272 legislation, which comes into force in 2017.  This year businesses with meters in class 05-08 will have their usage settled on a half-hourly basis thereby paying more or less depending on the time of day in which they use energy.

Knowledge of the key components of an energy bill (commodity and non-commodity costs) coupled with knowledge of building and equipment performance and controls is imperative if businesses are going to optimise when they use energy to reduce a growing energy bill.

Intelligent bureau teams, like Utilitywise, work with businesses to move energy consumption when non-commodity costs are higher (DUoS/ TRiAD) and take advantage of lower tariff periods thereby reducing not only kWh consumption each day but valuable £s/pence.

The Climate Change Levy (CCL) further enhances the need for this type of intelligent bureau offering, this tax on energy consumption will be increased from 2019, making the currently higher tariff periods even more costly to businesses.

Incorporating information on procurement, energy markets, legislation and tariff rates, the Intelligent energy bureau team can use its expertise and knowledge to help clients not only use less energy but use less at key times of the day making an average 15-20% reduction in consumption which results in greater savings from the bill.

Intelligent bureaus benefit business three-fold, from cost savings to energy consumption reduction and legislation compliance. The days of energy bureaus not being relevant are over – make way for the intelligent bureaus of the future.

Energy Assets Gets Tactical to Tackle Energy Waste

Energy Assets, one of Britain’s leading multi-utility networks, metering services and control companies, has launched a tactical tool to help industrial and commercial organisations identify energy waste that could potentially be costing them millions of pounds each year.

The analytical tool, developed to complement the company’s AMRdna service, powered by kWIQly, crunches half-hourly metered gas and electricity data to measure actual performance against what is verified to be the best possible consumption profile. This allows multi-site operators to see energy waste issues as soon as they emerge.

“Energy waste results from things as simple as not adjusting building heating or cooling systems to take account of changes in Daylight Saving Time, outside weather conditions and leaving lighting on overnight,” says George Catto, Client Services Director at AMRdna. “Our algorithm uses detailed consumption data to ‘learn’ what optimal performance should look like within individual buildings and across portfolios – and when exceptions occur, for example when equipment is left on accidentally, the system flags a deviation.”

Energy managers have historically used automatic monitoring and targeting systems to benchmark performance, but this does not offer true insight into optimal energy performance, only variation over manually set metrics. AMRdna’s software automatically remodels energy parameters on a daily basis, using half hourly gas and electricity data to spot unusual patterns of consumption.

“When it comes to energy efficiency, energy managers have exhausted most of the easy wins, such as LED lighting, and now what they need is a simple, fast and remote way of identifying energy waste hidden within their portfolio,” says George. AMRdna provides this information through automatic reporting or interactive web pages.

The insight provided by AMRdna is now being augmented by Energy Assets through the company’s Lynkswitch system, which provides energy managers with the ability to remotely control electrical loads, including switching off electrical loads should an unusual consumption pattern be identified.

Says George: “In one instance, our data showed a spike in energy usage in a retail outlet, which turned out to be an extractor fan running continuously. So we fitted a Lynkswitch module – and now the energy manager has remote control over the device if it needs to be switched off. When data-driven control such as this is replicated across entire building portfolios, the savings can be huge.”
Strategic analysis of energy consumption within buildings undertaken using the AMRdna tool has to date revealed potential savings of up to 15% for electricity and 30% for gas.

“Our forensic approach to energy waste is certainly gaining traction in the retail sector and is also creating a lot of interest in the public sector, where energy managers can be responsible for a portfolio of hundreds of buildings. For them, the analysis of existing consumption data provides a very effective and economical way of identifying opportunities for eradicating energy waste.”

Site surveys could lead to significant energy savings

Energy savings of up to 40 percent can be made, starting when a company agrees to a site survey, it has been revealed by pump specialist, Dura Pump.

Pump systems used in commercial environments often waste a huge amount of energy, through common issues such as incorrect specification, or running constantly at full power when such capacity is rarely needed.

Dura Pump visits thousands of sites each year and at a majority of them, regardless of sector, there are opportunities to create significant energy savings. After improvement works are specified and carried out, the payback in reduced energy costs can be achieved in as little as six months.

A spokesperson at Dura Pump said “Most facility or site managers are unaware of the huge opportunities to save resources. On the few occasions where they are aware, they can be unsure of how to go about making improvements.”

To improve awareness of energy-saving opportunities, and as an incentive to save energy, the firm has announced it is offering a free luxury hamper with every quotation that ensues from a site visit, until the end of October 2016.

Dura Pump’s team of friendly experts have been helping companies with their pumping systems for 10 years, and take pride in being able to support their customers at the same time as honouring their commitment to the environment.

Minimise Energy helps London university cut carbon emissions by 47%

Minimise Energy has installed new LED lights at London Metropolitan University’s Holloway Road campus, reducing the building’s lighting energy consumption costs by £55,000 a year and cutting annual carbon emissions by 225 tonnes.

The university’s ambitious sustainability programme has resulted in it being named the number one university in England for carbon reduction. The lighting upgrade is the latest part of this programme.

The programme required an eight-strong team from Minimise to replace outdated and inefficient T8 lamps and panels throughout the Victorian blocks which make up the Holloway Road Campus.

“The campus comprises a mix of classrooms, lecture theatres, offices, a gym, dance studios and ancillary spaces,” explained John Hatt, Contracts Director, Minimise Energy.

“Most of the buildings are more than 100 years old and have been subjected to an ongoing refurbishment programme. As a result, the lighting and control infrastructure is complex.”

The LED upgrade was completed during term time, with most work carried out between 7pm and 4am to keep student disruption to a minimum.

“The campus is a 24/7 environment. Meticulous planning and attention to health, safety and on-site security was essential at all times,” said John Hatt.

The LED lighting upgrade forms part of a wider sustainability programme completed by the university under The Mayor of London’s RE:FIT framework.

“The programme was developed to help the university meet the targets set out in its carbon management plan, enhance the student experience, and reduce energy costs,” said Rachel Ward, Sustainability Manager, London Metropolitan University.

The programme also included the installation of photovoltaics (the university’s first renewable energy), energy efficient fans and air conditioning controls. The lighting upgrade was the largest part of the programme.

“This combined approach has been incredibly important,” said Rachel Ward. “We were named as the number one university in England for carbon reduction and have cut carbon emissions by 47%, putting us on track to achieve our 2020 target of 50%.

“The lighting alone is saving us around £55,000 per annum on electricity costs and has reduced our carbon footprint by 225 tonnes of carbon. The lighting has also made an improvement to the feel of the university, making it a bright and welcoming space for students,” she said.

The university is now focusing on ongoing student energy efficiency education, and also plans to instigate further sustainability upgrades in 2017 when it consolidates its three campuses into one.

Reduce energy costs with a holistic approach to energy management

With the climate discussions in Paris at the end of 2015, energy efficiency and usage reduction is understandably a hot topic. However, what does this really mean from an energy management perspective for facilities management?

You may well be happy with your current energy supply, usage and back-up support, but how do you really know that this is operating as efficiently as it can be? With energy costs likely to form a huge proportion of complete operating costs, the central task of energy management is to reduce cost for energy provision without compromising on the work processes. The only way of truly identifying this is by conducting a survey out, at the outset, to ensure all relevant information and system characteristics are gathered. Without a detailed understanding of an entire environment and what it is trying to achieve, it is very difficult to identify if a supply, with its associated load types, is even viable for power quality improvements. 

An effective survey will explore energy efficiency, conduct load or harmonic surveys and complete power quality investigations to give a complete picture. For example, what are the types of loads and what percentage do they represent? This could include heating, ventilation and air conditioning (HVAC) requirements, determining transformer type and what the tap setting are, right the way through to the levels of harmonic current and voltage distortion and how they are impacting on energy costs. The list goes on, but only then with the right information in place, can the right type of action or equipment be identified to ensure it will give the best return, while also allowing for redundancy and built in headroom.

Ultimately, an effective energy management approach needs to be an integral part of facilities management and in fact an essential part of a company’s overall strategy. It needs to encompass critical decisions on energy investments, while avoiding energy risks. Whilst also being transparent about the total cost of ownership (TCO) of equipment and maximising operating efficiencies, energy usage and running costs.

As Martin Pearce, Sales Director at Critical Power says, “Practically for facilities management, effective energy management is about adopting a holistic approach using a combination of tactics. This includes; market analysis of current energy supply, combined with site surveys to determine inefficiencies (and potentially efficiencies!), while adopting a turnkey approach for any installation changes required, so the headache is taken away.  However, it does not stop there, as it is important to minimise any downtime in the future by ensuring business continuity, through remote monitoring and regular service maintenance support.”

The likelihood is that energy management and efficiency issues will continue to proliferate as power demands increase and change. This is why it is so important that whatever the output from the climate conference in Paris, that businesses, particularly facilities management continue and in fact increase their focus on energy management. The pressure to address this will continue to be principally from a financial cost-saving perspective, however there is now likely to also be a shift in focus to it becoming more of an environmental one too.

Biomass specialists raising the bar with new training for firms

Ben Tansey, co-founder of re:heat

 BIOMASS heating pioneers re:heat are using their expertise to raise professional standards in the wood heat industry.

The North East team are being called upon for specialist training as more schools, hospitals and major businesses move away from traditional fossil-fuelled systems towards biomass.

Whilst there’s a rise in the number of firms installing and running the systems nationally, there are currently few relevant standards to help regulate the industry.

Yet despite the lack of standards, employers have an obligation to ensure operators of the specialist equipment are fully trained and understand the risks, benefits and maintenance requirements linked to biomass boilers.

Ben Tansey, co-founder of re:heat, said: “Whether it’s health and safety, risk assessment or refreshing the basics, employers have an obligation to make sure operators are competent when maintaining these innovative and large pieces of equipment.

“It is also key for staff to fully understand how to operate the systems effectively in order to secure the Renewable Heat Incentive (RHI) and avoid cost implications for businesses.”

With re:heat co-founder Neil Harrison elected to the board of directors for the Wood Heat Association (WHA) at the start of 2015, the business has increasingly been called upon to develop training packages to ensure operator competency.

Mr Tansey added: “We recently completed a successful operator competency review and delivered a bespoke training programme with Robertson Facilities Management who are responsible for the operation of multiple biomass boilers at sites across Newcastle upon Tyne.

“Following one-to-one reviews with each of their operators we were able to identify areas where we could offer support and guidance. We then developed a set of training courses to ensure a consistent standard and compliance with manufacturers’ requirements.

“Since launching re:heat in 2011 we have been aware of a real demand for training across the whole sector. The marketplace is increasingly crowded as companies from all manner of other industries, many without a solid grounding in biomass, move in.

“What we are delivering in the North East is a huge step forward in raising professional standards in the industry, contributing to the reputation of biomass heating as an option that is a sound choice for businesses and the public sector.

“With the RHI providing financial incentives for running biomass boilers, it’s vital that caretakers, operators and front-line engineering staff appreciate why biomass boilers need to run, what the possible risks are if they are not operated correctly and how to perform basic but essential maintenance.

“There are a limited number of relevant training courses in the biomass sector which is why we approached the Robertson Facilities Management team with a bespoke package of skills evaluations. As a result the biomass boilers they installed are being properly maintained and are therefore running more efficiently.”

Allan Dryden, regional manager for Robertson Facilities Management, added: “As a responsible employer we need to ensure that all of the operators of our biomass boilers understand why we use the boilers, how the technology works and what we need to do to look after them. The team at re:heat has delivered a great package of review, evaluation and subsequent delivery of an operator-friendly training package.”

Founded in 2011, re:heat’s innovation in the field of biomass sees the team informing Government reports and transforming heating systems in schools, hospitals and businesses across the UK.

Fit EC when replacing fans and gain more than just energy saving

A recent replacement of old failing fans in Fan Coil Units with high efficiency EC fans has shown that the return on investment is beyond just the energy saving. The facility management company has found that the simple control and monitoring offered by EC fan technology is a simple gain on the back of the financial benefit of upgrading to EC.

Until ten years ago all fans in Fan Coil Units were driven by AC induction motors. The fan speed was set by using a transformer to reduce the applied voltage to lower the speed. This method of speed control is not efficient and also limited to a few different voltage tapings on the transformer. In addition, when changing the speed someone had to get a ladder to remove ceiling tiles to then change a position of a switch.

Ten years ago ebm-papst introduced EC motor technology to Fan Coil Units. Not a new technology at the time as it was already utilised by the refrigeration companies in Food Display Cases and other industries such as Clean Rooms. It took a little longer for the HVAC market to pick up the energy saving benefits of EC technology. Ten years later EC technology is now an established technology and since the introduction of the 2013 building regulations is the main way to meet the more demanding specific fan power limit.

ebm-papst is still promoting EC in Fan Coil Units, not in new build but to replace failed and ailing AC fans in old installed fan coil units. A recent upgrade in the headquarters of a leading accountancy and auditing firm has shown that the benefit of EC technology is not just the energy reduction. When ebm-papst visited to discuss the potential savings versus the investment to change, the facility management company realised that there were other benefits too.

The facility management company commented that they never knew when a fan had failed in a Fan Coil Unit (FCU) until they had complaints. Also they could not adjust the speed of the unit due to changes in occupancy without disrupting the office staff or working out of hours. Despite these challenges, the solution was simple; use the speed control and monitoring features of the EC fans. If the return on investment is accepted to upgrade to EC fans then why not also fit simple monitoring and control using ModBus communication.

When the fans were upgraded on the first of the ten floors the control and monitoring arrangement was also fitted, as shown by the diagram. This included a control unit on each FCU to monitor the operation and control the speed of each fan. Two zone controllers across the floor link the FCUs to a central monitoring point on each floor. This unit monitor is the easily accessible point to remotely set fan speeds and monitor the floor. If a fault occurs then this is communicated by BMS to facilitate a controlled maintenance before the occupants notice a change.

What of the energy saving? The second floor of the east wing was changed first to prove the energy savings and benefits of the monitoring and control. Fans in 49 Fan Coil Units were upgraded to EC fans and the end result is a 75 per cent reduction in power consumption, some 24,000 kWh per year saved.

The end client is convinced and has now started the process to upgrade the remaining 1,200 Fan Coil Units as well as the more convenient monitoring and control system on the back of the investment.

Powerstar to exhibit new energy storage solution at Sustainability Live 2015

Powerstar will be showcasing their market-leading voltage optimisation solutions, including the newly launched pioneering energy storage system Powerstar Virtue on stand L20 at Sustainability Live at the NEC on the 21st – 23rd April 2015.

Since the turn of the century the patented Powerstar voltage optimisation solutions have been not only saving private and public sector organisations money on their electricity bills but cutting carbon emissions as well.

The UK brand has grown into a world-leader in its field and now its research and development team have pushed the boundaries even further with Powerstar Virtue.

Like all Powerstar solutions the system is guaranteed to save money, but it does much more than this and since its recent launch Powerstar Virtue has already attracted huge interest.

How does Powerstar Virtue work?

In simple terms, Powerstar Virtue uses the patented Powerstar voltage optimisation technology and harnesses the induced negative power feedback to divert the energy saved from the installation of a voltage optimisation system to a storage medium. The system allows for savings in electricity costs by enabling users to come off-grid during times of high tariffs, diverting to the energy stored during times of low demand.

The solution can also be integrated with on-site renewable energy generation to combine the energy saved from the voltage optimisation system with that generated from the renewable energy source. As a result, renewable energy can be made more reliable.

Powerstar Virtue’s load controller dictates the amount of power required and the master controller manages the output of power to the storage medium, and communicates with the Powerstar voltage optimisation system to charge the batteries efficiently, diverting any excess current during charging back to the grid.

Powerstar Virtue also allows users to become a VPS (virtual power station) reliably forecasting how much power will be available at all times so informed decisions can be made on when stored energy should be used, which will lead to significant savings on electricity and take advantage of National Grid led initiatives such as FDR, STOR and EDR.

Unique and patented – induced negative power feedback

Between 70% and 80% of the savings achieved through Powerstar voltage optimisation are through the induced negative power feedback – generated as a result of the unique, patented design of the technology, and a key component for the Powerstar Virtue system. The remaining 20% to 30% savings are gained from the improvement in equipment efficiencies due to appliances operating at a voltage more suited to their operating requirements.

Integrated with long established successful technologies

Powerstar Virtue is integrated with either a Powerstar MAX or Powerstar HV MAX voltage optimisation system, both established technologies.

Powerstar MAX is an electronic-dynamic, variable voltage optimisation system that provides a stable voltage output by automatically adjusting and maintaining voltage at the optimum level. Powerstar MAX is ideal for sites with fluctuating voltage, high night loads or critical equipment requiring additional security.

Powerstar HV MAX provides a combined solution to common problems, combining a super low-loss amorphous core HV/LV transformer with integrated variable voltage optimisation technology, allowing for 11,000V input (other inputs available) and regulated 380V or user defined output.

The super-low loss amorphous core transformer used in Powerstar HV MAX will provide 3% to 10% savings on traditional HV/LV transformers. It is ideal for larger facilities and manufacturing sites with their own transformers.

Energy Storage – the way forward

Energy storage has emerged as one of the best solutions to address the fact that energy grids around the world are struggling to cope with the surge in demand for electricity, which continues to accelerate – in the UK peak demand on the grid is expected to increase six-fold by 2050 – and Imperial College London’s Energy Futures Lab has estimated that energy storage technologies could generate savings of £10bn a year by 2050 in the UK.

Storing energy for use at a time when tariffs are high is a natural and obvious progression. Storage is also crucial if we want a significant part of our energy to come from renewable sources. This new system makes a ‘virtue’ out of that necessity, providing the energy user with greater control and flexibility over their energy supply to avoid energy wastage and maximise savings.

Powerstar awards

Not surprisingly a host of awards and accreditations have been bestowed on Powerstar solutions, recognising the huge strides the solutions have made in the energy management market, cutting costs, carbon footprints, and CO2 emissions, while at the same time protecting customers’ corporate social responsibility and reputations.

Email info@powerstar.com to arrange a meeting and a full demonstration of Powerstar Virtue with a Powerstar team member at Sustainability Live.
