EIC explores the benefits that firms can reap from conducting an energy audit and how to maximise the value of its findings.
Information is power
Energy audits provide firms with a clearer picture of their energy consumption patterns. Also, they can highlight existing points of weakness where wastage may be occurring as well as provide a foundation of knowledge for negotiating new energy procurement contracts.
As we approach the 2050 net-zero deadline, clarity surrounding energy usage – the major driver behind office-based carbon emissions – will become increasingly valuable.
Small to medium enterprises in particular stand to benefit greatly from the help audits can provide. Especially in navigating information barriers that conceal opportunities to improve their energy efficiency.
While a review of an organisations energy portfolio can seem daunting, technology can help lighten the load. Smart meters can keep an ongoing, up-to-date record of energy usage across an entire site.
Employing one of these devices essentially automates the local data-finding necessary to perform an effective audit. Given how vulnerable long-term metering is to human error, this makes their installation a wise first step in the process.
Metering alone can provide average energy savings of 10% and comprehensive sub-metering can raise these savings by a further 30% according to the Carbon Trust.
An on-site walk around compliments the auditing process since it can identify sources of inefficiency missed by meter readings. Old equipment in need of replacement is one common example. Another being wholesale temperature regulation of buildings since this often does not reflect actual occupancy levels in individual rooms.
The fruits of an energy audit
With the audit complete, realistic energy efficiency targets become foreseeable and have a baseline for comparison of progress. Such a foundation is crucial for effective engagement with carbon compliance schemes like SECR and CCA.
Firms might follow up by installing site-wide building management systems that can provide further clarity on utility consumption.
Such a system can remotely govern space occupancy, dynamic temperature regulation and air quality from a single platform. The latter of these also affects the health and productivity of those within. Thus, intelligent air quality management can represent a twofold investment.
EIC understands the potential of informed utility management, hence why it provides all these services under a single banner.
Whether it be by supporting data collation with expert metering guidance or exploiting the discoveries that an audit yields with a single-platform building management system, EIC can provide the technical expertise needed for enterprises to maximise the benefit of an energy audit.
EIC explores the carbon-negative office spaces that are emerging, their role in the green recovery and the technology that make them possible.
Favour the bold
The path to net zero is fraught with obstacles and among these is the carbon intensive nature of the mainstream construction sector. Materials like concrete are extremely resource intensive to produce.
While often offset on a citywide scale, some firms are beginning to focus on the buildings themselves and work sustainability into their initial designs.
Blazing the smoke-free trail are Norwegian architects Snøhetta, who will design exclusively carbon-neutral buildings over the next decade.
The aim is then that from 2030 onwards, Snøhetta will focus on creating carbon-negative designs.
Carbon negative structures either generate more energy than they consume, or sequester more carbon than they produce. The figure includes expenses from initial construction and materials, as well as operation and decommissioning.
Elusive costs like these are problematic, with 85% of building emissions generated by materials and construction, before the structure is ever used.
“For the next 10 years, we have the ambition of having projects on the table that will become CO2 negative in the cradle-to-cradle definition… This means we have to understand the embodied energies and all the materials used.”
-Snøhetta co-founder Kjetil Thorsen
Balancing the books
Since less intensive materials suited to large scale construction are not yet widely available, balancing through generation will be key. Solar is central to Snøhettas plans, with structures taking about 60 years to hit carbon negative with embedded generation. The architect recently completed its Powerhouse Brattørkaia project, which boasts an identical timeline for net negative. The Powerhouse also sports a cutting edge ‘wedge’ shape designed to maximise exposure to the sun’s rays.
While this may seem like a life sentence for business leaders, it is refreshing that groups like Snøhetta are beginning to think in terms of multi-generational gains.
Bywater Properties are leading a similar development project aimed to create the lowest-carbon workplace in London. The office, named ‘Paradise’ for the road it occupies: Old Paradise Street. Supermarket, Iceland has already secured the majority of this space, planting a green flag for the brand in the minds of its customers.
It is no secret that the attraction of short-term gains have significantly contributed to the environmental challenges we now face.
However, vision extending beyond the next board meeting can help transform the UK and global economy to reach net zero. Carbon negative buildings are a part of that vision.
Unfortunately, that can feel exclusionary to firms that have already established their sites and do not have the luxury of completely retrofitting them.
The complex, modular nature of structures does mean that while carbon negative may not be feasible, ‘carbon-light’ might be possible.
Intelligent building control is one of the most effective ways to improve your carbon profile. Primarily because it streamlines the carbon-producing elements of a building, mainly utility consumption, and shrinks carbon footprint as a result.
A holistic ally in carbon reduction is the addition of green spaces to working environments, since these also sequester carbon.
On-site generation further reduces your reliance on the grid and the subsequent sequestered carbon in meeting demand – particularly across long distances.
Other benefits include improved energy supply security, added leverage in procurement talks and a better carbon profile for crucial legislation.
EIC understands that intelligent building design and frugality around resource-use work in hand in glove. As such, EIC offers a comprehensive carbon service combining building management, intelligent procure and compliance acumen.
Marriage of these three pillars means unlocking the full potential of sites, and leveraging for the benefit of all. EIC’s full offering is on its services page.
EIC explores the potential benefits to productivity that can be generated by effective and responsive environmental control, as well as the boon to cost saving and compliance processes it can provide.
Setting the scene
The percentage of the labour market now working from home (WFH), due to the lockdown imposed to fight the spread of COVID-19, is unprecedented with Finder estimating that 60% of the UK’s 33.7 million labourers are now working remotely.
Most commercial enterprises are being forced to reevaluate the way their staff perform their roles and the limitations imposed by location and direct proximity to colleagues and management.
While WFH has demonstrated some obvious benefits, time saved by cutting out commutes for example, there are still many roles that require working from site.
Additionally, many employers will choose to return to a state of normality for logistical reasons like communication and conferencing that suffer novel limitations when used remotely.
One of the upsides of COVID-19 will be an increased awareness and respect for the effect of working environment on productivity as well as on employee health.
Making informed decisions
Air quality, temperature and humidity are fluctuating qualities of an internal environment while lighting is more static. However, they can each be directed according to need, tracked for data analysis and there is evidence that all of them affect productivity in the workplace.
“System design and the deployment of correctly implemented controls are the single biggest components to ensuring environmental conditions are correctly maintained.”
-Mark Longley, Head of Operations Solutions, t-mac
The widespread attraction of commercial air conditioning is that it can provide a stable and consistent utility cost to weigh against air quality control, meaning that windows can be ‘sealed’ to prevent costly and unpredictable heat loss.
Unfortunately, a lack of CO2 monitoring can lead to saturation in the internal environment which, in turn, can impair the cognitive functions of your team and lead to a drop in productivity.
A 2015 report from Harvard University, titled “Economic, Environmental, and Health Implications of Enhanced Ventilation in Office Buildings”, demonstrated that:
“The public health benefits of enhanced ventilation far exceed the per occupant economic costs… Even with conservative estimates, the increased productivity of an employee is over 150 times greater than the resulting energy costs.”
Ironically too much CO2 can often trick the brain into thinking that temperatures are uncomfortably high-meaning that air conditioning can actually be counterproductive to its original purpose if it is unable to respond dynamically to your needs.
“I don’t think our field has done a good job of reaching out to the real estate developers, managers, and owners of businesses that can make this change… I don’t think it’s acknowledged that changing these factors can make a difference.”
-Piers MacNaughton, Harvard
A discussion on air quality control necessitates one on temperature regulation since the two are often confused with one another. System-wide temperature control has been a standard in modern work and living space for decades, however its adaptability leaves something to be desired.
The current fluctuations in British weather are an expected side effect of climate change however the thermal regulation of most offices isn’t equipped to respond to wide swings in temperature or humidity ranges-both of which affect our perception of temperature.
Additionally, recent reports have demonstrated human productivity is extremely sensitive to changes in temperature:
“The results show that performance increases with temperature up to 21-22 o C, and decreases with temperature above 23-24 o C. The highest productivity is at temperature of around 22 o C. For example, at the temperature of 30 o C the performance is only 91.1% of the maximum”
A collaboration between the Lawrence Berkeley National Laboratory and Helsinki University of technology, the report also stated:
“There is an obvious need to develop tools so that economic outcomes of health and productivity can be integrated into cost-benefit calculations with initial, energy and maintenance costs.”
Finally, the internal lighting systems a business utilises can have a dramatic affect on productivity since they have a direct relationship with their staff’s circadian rhythms, the aspect of our biology that tells us when it is time to be engaged and time to rest.
Psychological studies have also shown that people’s mood and productivity can be affected by the ‘temperature’ of light as well i.e. whether light feels warm or cold to look at.
“There is growing evidence for a link between lighting conditions, shift-work and biological health conditions: an area likely to receive more attention from researchers in future.”
–Lighting, Well-being and Performance at Work, by Professor Jo Silvester and Dr Efrosyni Konstantinou
All that being said, the key question is how to obtain the data and control necessary to make these systems work for you rather than just being extra columns on the expense report.
Considering these elements as potential assets rather than liabilities might seem counter-intuitive but when the application of something has the power to affect productivity this dramatically, it is only a liability while it is not under our control.
As Jones Lang LaSalle’s 3-30-300 rule posits, for every dollar or pound spent on utilities like lighting and heat, you are likely to spend a hundred on people so why not make those costs go further by making what you spend on utilities count towards your people too.?
The recent SECR deadline also served as a sobering reminder of the importance of effective utilities management and regular reappraisal of existing practices.
Intelligent building management will continue to grow more and more sophisticated, allowing greater adaptability to the needs of clients, staff and business owners, and EIC can help you to leverage this technology to increase both your staff’s productivity and your bottom line.

This weekend will see the official start of British Summer Time (BST), as clocks will spring forward one hour on Sunday 29 March 2020. How can IoT controls help you adapt to the clock change?
The clock change accelerates the seasonal trends towards lower demand during the warmer, lighter summer months.
Historically, the scale of peak power reduction following the clock change has been around 10%. However, early forecasts show an expected 5% drop in average demand for the week following the change. An unseasonably mild winter has kept demand levels depressed in general this year.
The advent of demand management and significant developments in energy efficiency and IoT controls have made the UK consumer more proactive when it comes to when and how they use electricity. It can be seen in the graph that overall demand, before and after the clock change, is trending downwards.
The role of renewables
The increase in wind and solar capacity in recent years has contributed to the overall demand reductions. Higher volumes of on-site renewable capacity allow more generation to be provided off-grid as homes and businesses generate their own electricity supply during windy or sunny spells. This reduces demand on the national transmission system. The high levels of solar availability during the summer season were a particularly strong influence on demand levels this year as on-site solar panels increased embedded generation, reducing demand requirements for the transmission network.
Renewables continue to deliver a growing percentage of the UK electricity mix. The 2019 share for wind, solar, hydro and bioenergy electricity sources was 31.8%, up from 27.5% in 2018.
How clock change impacts behaviour
The graph above shows how the peak demand changes before and after the clock change. The earlier evenings cause an increase in electricity demand as consumers use more sources of light and heat. Post-change, a longer day-time means that less lighting is used through the day and also has the effect of pushing daily peak demand to later in the evening.
The graph shows that over the last five years before the clock change, peak demand occurs at around 6.30pm in the weeks leading up. However, once the hour is gained peak demand occurs later in the day, at around 8.00pm on average.
The impact of coronavirus
As the COVID-19 situation has developed it has become increasingly clear that there will be an impact to demand levels. The graph below shows the effect of the temporary closure of schools and some businesses, with peak demand forecast to fall around 1GW on average week-on-week. The combination of the further closure of offices and the clock change will likely see demand drop heavily over the coming week.
React to changes in real-time
How can you best react to changing demand patterns and sources of generation? How can you ensure time-consuming but critical processes affected by the clock change are carried out efficiently?
With IoT-enabled controls, your business can access all the key information about your sites usage on a single platform. This allows you to make instantaneous changes to multiple sites at the touch of a button.
One of our multi-site clients previously spent three weeks making adjustments ahead of the clock changes. This involved engineers attending each site and changing multiple systems. With our system we could make the same changes in a matter of seconds.
Our sister company t-mac Technologies Limited (t-mac) has re-launched into the metering and controls marketplace. The energy and building insight specialist is a brand in its own right once more.

The seasonal trend towards higher demand during the colder, darker winter months will accelerate as a result of the clock change. This will place pressure on power margins and could lead to spikes in electricity prices, should supplies struggle to meet the higher demand.
Energy demand will jump but the downward trend continues
Current forecasts indicate the peak demand for the week following the clock change will be 9% higher than the previous week. Consumption is set to increase by nearly 4GW to more than 45GW overall as an earlier sunset (around 4:30pm) increases lighting requirements during the traditionally higher post-work demand period. If so, this would be the highest percentage change on record, with the 3.8GW rise nearly three times larger than the demand bump seen in 2015 or 2014.
However, the ongoing trend in reduced energy consumption has continued, meaning that demand is rising from a far lower base. Expected demand before this month’s clock change is 6GW lower than the most recent peak in 2015.
Furthermore, the expected post-clock change peak is the lowest on record.
Weekday Peak Demand for October
Demand – Week before Clock Change (GW)
Demand – Week After Clock Change (GW)
Improvements in energy efficiency have been reducing electricity use for the last 10 years. A large part of the reduction in peak demand has been the use of new smart technology, resulting in more efficient appliances that are able to do more with less. A switch away from incandescent light bulbs is also a contributing factor, particularly during the winter months, when lighting demand plays a far increased role in consumption.
Aside from a well-documented cold snap in February and March (remember the Beast from the East?) peak demand during 2018 has been largely below that of previous years, continuing a consistent year-on-year reduction in consumption overall.
React to changes in real-time with smart building controls
How can you ensure time-consuming but critical processes affected by the clock change are carried out efficiently?
IoT controls can help you alter site settings remotely, so you’re in full control when the clocks change. There’s no need to make arduous manual changes – with IoT, you can make the necessary changes at the touch of a button.
With our Building Energy Management solution, we’re introducing the next generation of smart building controls. Our innovative solution brings together the required technologies to integrate all your critical energy systems. This enables your business to access real-time insights on key energy and building systems via single, remotely-managed platform.

Each year from November to the end of February, National Grid use peak demand data to calculate how much energy users should pay in electricity transmission charges as part of the Transmission Network Use of System (TNUoS) scheme. To avoid higher costs you can undertake Triad avoidance.
What are Triads?
Triads are the three half-hour periods with the highest demand between 1 November and the end of February, identified by National Grid. Each Triad must be separated by at least 10 days. This means consecutive days of high demand won’t result in multiple Triads. Businesses that reduce their usage during these high demand points will lower their future electricity transmission costs.
You can find out if your business is affected by Triads here.
How will you know when to act?
Our Triad Alert Service monitors different influencers to predict the likelihood of any particular day being a Triad and automatically sends that information promptly to our clients. You can then take informed action to avoid high usage during these more costly half-hour periods, while minimising disruption to your everyday activity. Our daily report can help you plan ahead with an overview of the next 14 days alongside a long-term winter outlook.
Predicting Triads is very challenging; falling demand and changing usage patterns mean Triads are no longer guaranteed to occur at the height of winter. Season 2017/18 included the latest Triad on record and weakest demand levels since the early 1990s.
We’ve helped hundreds of clients avoid these transmission costs by providing them with the tools needed, giving EIC an enviable track record in Triad prediction. Previously, one client saved £800,000 by acting on insight from our Triad Alert service.
Last season we hit all three Triad periods, issuing just nine red alerts, lower than any other TPI or supplier – a testament to our in-house technology, analytics, and expertise. Of course, calling an alert every weekday would generate a 100% success rate but we recognise the negative impact this would have. Businesses could incur major damage to their revenues if required to turn down production each day for a quarter of the year ‘just in case’.
By issuing fewer alerts we ensure our clients are not unnecessarily disrupted from their day-to-day activities. Those that took action in response to our alerts last season cut demand by an average of 15% compared to standard peak-period half-hour consumption.
Intelligent buildings, smarter business
By forecasting when Triads will occur, we empower our clients to take control of their consumption to reduce their energy use and lower their bills. Businesses can react to our Alerts simply by cutting demand during suspected Triad times or by load-shifting.
Load-shifting involves moving the most energy-intensive tasks of the day to a time when it’s less likely that a Triad will occur, for example early in the morning. This enables you to avoid Triads without reducing your overall daily energy use. Building controls make this easier. With our IoT-enabled Building Energy Management solution, we’re introducing the next generation of smart building controls. Our innovative solution brings together the required technologies to integrate your critical energy systems with a single, remotely-managed platform. This means you can manage your buildings in real-time.
The changes have come from an evolution in how energy is being used, and those who successfully manage these demand patterns, particularly if combined with Demand Side Response (DSR), could see significant cost savings.
Analysis from EIC has shown that maximum summer demand (seen between May and August) has fallen 17% in the last decade. From a peak of 44GW in 2012, maximum consumption for the current summer has fallen to just 35GW.
This near 10GW loss in demand is similar to the reduction seen during the winter. Furthermore, it’s not only peak consumption that’s been reduced but baseload generation. Minimum summer demand has fallen by 19% since 2009. How much of this is down to efficiency improvements or consumption moving behind the meter is unclear. However, the change does mean National Grid has nearly 10GW less electricity demand to manage on its transmission network.
The trend can be seen more clearly when broken down by month. Average peak demand during May 2012 was over 39GW. This year that figure was just 31.5GW, a reduction of over 7GW in only six years.
Improving energy efficiency
The cost of LED lighting halved between 2011 and 2013. During this time, consumers switching towards the more efficient bulbs helped facilitate a strong drop in demand. This could be helped further with news that the EU will ban the use of halogen lightbulbs from 1 September 2018.
Another major explanation for the demand drop, aside from efficiency improvements in appliances and lighting, is the significant growth in small-scale on-site solar capacity over the same period. Small-scale distribution connected solar has a capacity of under 4KW but the number of installations has grown from under 30,000 in 2010 to nearly 900,000 in 2018. An increase of almost 2,900%.
The total capacity of the small-scale solar now available is over 2.5GW, which is not far off the total capacity for the new Hinkley Point C nuclear power station.
As the use of small-scale solar (the type typically installed on housing or commercial property) has grown demand has fallen. More and more of within-day demand is being met by onsite generation. Consumers can take advantage of the bright and warm summer weather conditions to generate their own solar power, thus reducing the call for demand from the transmission network.
The solar impact
The introduction of high volumes of solar generation to the grid – total capacity across all PV sites is over 13GW – has also significantly altered the shape of demand. Consumption across a 24 hour period has flattened in recent years.
The traditional three demand peaks (morning, early afternoon, and evening) have shifted closer to the two peak morning and early evening winter pattern. The ability to generate high levels of embedded – behind the meter – generation during the day in the summer has flattened and at times inverted the typical middle peak. This has left the load shape peaking in early morning (as people wake up) and later in the evening, as people return home from work.
The absolute peak of the day has also shifted in time, moving from early afternoon to the typical early evening peak of 5-5:30pm, again similar to the winter season.
The below graph shows the change over time of the July load shape, which highlights both the reduction in demand and the change in shape, with consumption flattening during daylight hours as a result of behind the meter solar generation dampening network demand. With electricity costs – both wholesale and system – reflecting supply and demand, if consumption is being changed, then it also has an impact on these costs.
Stay informed with EIC
Our in-house analysis highlights the impact of onsite generation on load patterns and the extent to which demand can be changed by taking action, and subsequently how behaviours can alter a business’ energy costs.
If you can shift demand away from historical high consumption periods, you can cut your energy costs and make significant savings. One such way to do this is by using smart building controls, such as our IoT-enabled Building Energy Management solution.
