Here comes the Sun

EIC explores the benefits and future of on-site solar generation for businesses, how COVID-19 has highlighted and bolstered the strengths of solar power and how EIC can help businesses engage with the technology.

The wild blue yonder

Lockdown, while effective, has been a source of ongoing financial and emotional strain for many in the UK and businesses are no exception. However, there have been a number of benefits to this economic slowing that perhaps are going overlooked.

Chiefly, air pollution, in proportion with industrial energy demand, has dropped significantly. Combined with the severe oversupply of Oil and faltering resilience of fossil fuels generally, this has given solar generation the opportunity to enjoy a moment in the sun. 

However, solar is not a recent arrival to the energy scene, existing theoretically since at least 1839 thanks to French scientist Edmund Bacquerel. Bacquerel’s work was groundbreaking because it was the first time that solid material with no moving parts had been used to convert sunlight directly into electrical energy.

A guiding light

Since 1839, we’ve come a long way and furthest perhaps in the last five years, during which time the costs of solar have halved while storage options have improved consistently with the introduction of graphene and vanadium technology.

The conditions of lockdown have demonstrated that renewable energy sources are likely to be the most resilient to the supply chain disruptions that a major crisis can create. 

In fact, EU solar generation jumped by 28% year-on-year, between March 28th and April 26th of this year compared to 2019, breaking generation records while doing so. 

Energy security is a basic necessity for the survival of any business and, as such, will be a subject of great scrutiny throughout lockdown and in its aftermath. Novel technologies like on-site generation will become more attractive, not only for their resilience but for the savings that their flexibility offers. 

The use of on-site photovoltaics can also improve a company’s carbon profile while providing a measure of protection against supply failure. 

EIC manages around 12TWH each year and with over 40 years industry experience, we are able to create bespoke energy solutions for your needs. We can help you engage with on-site generation, saving you as much as 20% on your energy usage or 40% when combined with on-site battery storage. Better still, in times of plenty, you’ll be able to sell excess energy back to the grid and further offset energy costs. 

Our solutions page contains full details of our on-site generation and storage offerings, as well as further information on the compliance service we provide that can be bolstered by such technology.

 

Clarity of vision: Intelligent buildings

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

Air quality

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

Temperature control

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.”

Lighting

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

Closing thoughts

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.
